Samsung details the 108MP camera sensor tech packed in the Galaxy S20 Ultra smartphone

15 Feb

Samsung has published technical details on the 108MP ISOCELL Bright HM1 ‘Nonacell’ image sensor found in its newly launched Galaxy S20 Ultra smartphone. The image sensor features 108-million 0.8?m pixels and a 1/1.33in size, as well as Smart-ISO and Nonacell technologies to produce what Samsung claims are ‘crystal-clear’ and ‘vivid’ 8K videos and high-resolution images.

Nonacell builds upon the Tetracell technology Samsung unveiled in 2017; rather than featuring a 2×2 array like the older tech, the Nonacell features a 3×3 arrays of the same color filter. This allows chunks of nine 0.8?m pixels to be merged into what is essentially a single 2.4?m pixel. This results in more than double the light absorption offered by the Tetracell tech, according to the company.

The downside is that there is a larger gap between pixels recording different colors, meaning that the ‘re-mosaic’ algorithm, that tries to reconstruct what a conventional 1×1 Bayer sensor would have captured, faces a more difficult challenge. So you won’t ever get the lever of color resolution that a conventional 108MP sensor would give.

Other ‘advanced pixel technologies’ like Smart-ISO help produce what Samsung calls ‘ultimate results under any lighting condition,’ including particularly challenging mixed-light environments. The camera’s HDR tech involves assigning exposure lengths to each and every pixel for multiple simultaneous exposures, enabling real-time HDR previews.

Rather than using a mobile processor, Samsung says its sensor directly converts pixels via ‘an embedded hardware IP.’ Other features include electronic image stabilization that uses gyroscope hardware, Super-PD phase-detection tech and up to 3x lossless 12MP zoom that doesn’t require upscaling.

The use of ISOCELL Plus tech, meanwhile, deals with the color interference that would otherwise arise from the Nonacell system, according to Samsung:

As the number of adjoined cells increase, so does color interference, making pixel-binning technologies more challenging, While such difficulties had limited Nonacell to a theory, the HM1 was able to realize the method by adopting Samsung’s ISOCELL Plus technology, which dramatically reduces crosstalk and minimizes optical loss as well as light reflection.

In addition to the 108MP sensor, the Galaxy S20 Ultra model features a 12MP wide-angle camera and a 48MP telephoto camera, 10x Hybrid Optic Zoom and ‘Super Resolution Zoom’ that uses AI for up to 100x zoom. The model’s ‘selfie’ camera, meanwhile, features a 40MP sensor with the ability to ‘shift’ to 10MP with larger pixels for higher quality images captured in low-light settings.

The S20 and S20+ models feature lesser specs with 12MP wide-angle and telephoto cameras, as well as a 64MP telephoto camera. A full breakdown of the camera hardware found in these three smartphone models is available on Samsung’s website.

Sony packed serious phase detect AF into these new 4K palm-style camcorders

16 Sep

If you’ve used a palm-style camcorder to try and film action at any point over the past several years, you’ve probably noticed an issue: most of these camcorders are god awful at finding and holding focus, usually relying exclusively on contrast detect AF or simply the deep depth-of-field their small sensors made requisite. Well, not anymore.

Sony has just debuted three new 4K camcorders with advanced, relatively large sensors aimed at three different tiers of users. But all of them have one thing in common: blazing fast, 273-point phase detect autofocus systems similar to (and, in fact, a bit more advanced than) the system found in Sony’s new RX10 IV. More advanced because the camera allows you to further customize features like AF Drive Speed, Tracking Depth Range and Subject Switching Sensitivity to make sure you nail every shot. We’re also told the focus ramping is more sophisticated, if you ask the autofocus to rack between two subjects. The hi-res touchscreen LCD should make focus easy and intuitive as well.

All three palm-style camcorders feature this same autofocus system, a 1-inch type stacked Exmor RS CMOS image sensor, and support 4K ‘Instant HDR’ recording using Hybrid Log Gamma (HLG) technology. However, not all three are meant for the same user. The AX700 is for serious amateurs, the NX80 for semi-pro video shooters, and the Z90V packs in some interesting broadcast capabilities such as XAVC L format recording, 3G SDI connectivity, and other features the support news reporting.

Of course, at $ 1,900 for the ‘cheapest’ model, it was obvious from the get-go that Sony wan’t aiming for the entry-level crowd with this release.

The most beginner-friendly model, the FDR-AX700, arrives in October for the aforementioned price of $ 1,900. The two higher-end models, the HXR-NX80 and PXW-Z90V, both arrive in December for $ 2,300 and $ 2,800 respectively. To find out more about any of these camcorders, read the press release below or visit the Sony 4K Palm website.

Press Release

Sony Unveils First Camcorders with Phase-detection AF

Sony’s newest camcorders are its first to feature phase detection Auto Focus (AF), and expand its line of 4K and HDR-capable tools for shooting applications ranging from video enthusiasts to corporate and events to broadcast news and TV production.

The three new palm-style models are the XDCAM PXW-Z90, the NXCAM HXR-NX80 and the Handycam FDR-AX700. The camcorders’ Fast Hybrid AF system ensures highly accurate focusing and tracking — especially useful during 4K shooting — delivered by 273 phase-detection AF points that cover approximately 84% of the shooting area, high-density placement of autofocus points and a newly developed AF algorithm. In movie recording mode, the appearance of phase-detection AF frames indicates the focused area and easily allows users to monitor a subject that is in focus.

Each camcorder combines fast and reliable AF adapted for video shooting with a 1.0-type stacked Exmor RS CMOS image sensor. The new camcorders support 4K HDR recording with Hybrid Log-Gamma (HLG) offering an Instant HDR workflow to produce high-quality HDR content smoothly. The Instant HDR Workflow enables simple shooting, editing and viewing of HDR content in HLG, without the need for color grading during post production.

The new camcorders feature a high-resolution OLED viewfinder (0.39-type OLED, 2,359k dots) and advanced touch screen operation, on the 3.5-type large LCD screen (1,555k dots), to allow users to quickly switch focus from one subject to another, while the AF Drive Speed, Tracking Depth Range and Subject Switching Sensitivity can all be configured as required for different subjects and content styles.

Simple, multi-camera live production

The PXW-Z90, HXR-NX80 and FDR-AX700 camcorders all work seamlessly with Sony’s MCX-500 live producer, a compact, cost-effective switcher that makes it easy for one operator to run a multi-camera live event. With the switcher and Sony’s RM-30BP controller, a Tally icon appears on each camera’s LCD panel and viewfinder. A red icon indicates when the shot is live (PGM) while Green indicates preview mode (NEXT).

The MCX-500 supports mixing between eight video sources, four stereo embedded audio channels plus two XLR Inputs, and a dedicated Title Input, up to nine video inputs, and five stereo inputs including XLR. Internal recording and live streaming is also possible via Ustream, Facebook Live and YouTube Live.

Users can also synchronize timecode among multiple camcorders using Sony’s free Content Browser Mobile 3.0 app with optional CBKZ-WTCL upgrade and devices running iOS® (9.0 – 10.3) or Android® (4.4 – 7.1) operating systems.

Versatile Shooting Capabilities

The new camcorders enable the following key technology and features to support versatile shooting, including:

  • 4K full-pixel readout without pixel binning using an enhanced BIONZ X™ image processing engine
  • Super Slow Motion recording up to 960fps, which is industry leading among palm categories and Slow & Quick Motion Full HD recording up to 120fps.
  • S-Log3/S-Gamut3 capabilities for users to create and work with images as they desire.
  • 29mm wide-angle ZEISS® Vario-Sonnar T* 12x optical zoom lens and 18x Clear Image Zoom
  • Less image distortion (rolling shutter phenomenon), in comparison to conventional models, when shooting moving subjects in motion

Workflow efficiency benefits such as proxy recording, relay recording and simultaneous backup recording are also delivered thanks to the new camcorders’ dual memory card slots and multi-camera operation capabilities supported by TC (time code)/UB (user bit). The new camcorders also have REMOTE terminals, Multi-Interface Shoe™, and HDMI Type A for enhanced operability.

The new models also feature dual XLR audio input, a detachable handle, and access to Content Browser Mobile a supporting smartphone application to enable Wi-Fi® monitoring, Camcorder remote control and wireless timecode sync between multiple cameras.

The PXW-Z90 also includes several features to suit broadcast-specific production requirements: XAVC L format recording, which provides high-quality images at 4:2:2 10 bit (HD) and 4:2:0 8 bit (QFHD) in addition to conventional broadcasting MPEG2HD format recording; 3G SDI connectivity for compatibility with existing broadcasting equipment; and networking functions to support news reporting, such as compatibility with XDCAM® air, Sony’s cloud-based ENG subscription service. The HXR-NX80 and FDR-AX700 adopt XAVC S, an extended format of XAVC for consumer use.

The following is planned availability and suggested list pricing for the new models:

  • FDR-AX700 – October 2017, $ 1,899 USD
  • HXR-NX80 – December 2017, $ 2,299 USD
  • PXW-Z90V – December 2017, $ 2,799 USD

Transformers: 2 Beijing Houses Packed Full of Space-Maximizing Tricks

08 Dec

[ By SA Rogers in Architecture & Houses & Residential. ]

blue-architecture-studio-narrow-5

Think you’ve seen it all when it comes to ideas for saving space in small houses and apartments? Beijing’s B.L.U.E. Architecture Studio is here to prove you wrong in the most delightful way, with a series of transforming elements and incredibly clever layouts in two tiny ‘hutong’ alley houses. Working with lots as small as 258 square feet that are squashed between existing buildings, the architects managed to produce functional, comfortable, private residences full of natural daylight and enough space for multi-generational families.

blue-architecture-studio-narrow-1

Both homes butt up against other structures, making it impossible to incorporate windows into the design. B.L.U.E. added skylights to both, utilizing open-plan lofted layouts inside to encourage a bright and cheerful atmosphere. The first home is on a narrow L-shaped lot and features a cool glass-filled rear wall that opens all the way up to the courtyard.

blue-architecture-studio-narrow-2

blue-architecture-studio-narrow-4

blue-architecture-studio-narrow-6

Inside, beds and children’s play areas are lofted above a pale wooden built-in full of sliding elements, fold-down tables, transforming stairs, beds that instantly double in size, retractible walls and a modest-sized table that expands to seat six diners.

blue-architecture-studio-narrow-7

blue-architecture-studio-narrow-3

The second house is even smaller, with a nearly-identical arrangement of skylights and cabinet-packed walls revealing an array of unexpected features when opened. Extra countertops and work surfaces pop out of the wall facing the galley kitchen, and storage space stretches from the floor to the ceiling.

blue-architecture-studio-hutong-2

blue-architecture-studio-hutong-3

Beneath the lofted bedrooms for the owners and their kids, a third bedroom area doubles as an extra dining space. Remove the mattress to reveal a pop-up table and cushioned bench seating that you climb into like a retro conversation pit, or lay it back down and pull down the blinds for privacy. A second table folds down from the adjacent wall in seconds, with storage cubes doubling as stools.

blue-architecture-studio-hutong-1

blue-architecture-studio-hutong-4

From the pictures, it looks like there are even more built-in elements that aren’t demonstrated in GIF form, like a mysterious hatch in the dining room floor. The whole setup is clean, modern and uncluttered enough for a minimalist’s sensibilities despite so many people living in such a small space – an inspiration for all the tricks and hacks we’re going to have to come up with to boost housing density in cities with burgeoning populations.

30 Action Packed Panning Images

09 Apr

Adding a feeling of motion to your images by using a slow shutter speed can be very effective. One technique to do that is panning, where you move the camera to match the subject and it blurs the background and keeps the subject relatively sharp.

You can pan just about anything that’s moving. Let’s see what these photographers found that they could pan:

Action packed: Shooting the Sony a6300 in Miami

09 Mar

Sony a6300 shooting experience

by Dan Bracaglia

Shot during an 8 fps burst. Check out the video below for a view through the electronic viewfinder of this burst being captured. Note: image has been cropped in to taste. ISO 250, 1/1250 sec at F5.6. Shot using the Sony FE 70-200mm F4 G OSS at 200mm.

Sony invited us to come out to Miami and field test the company’s new a6300 mirrorless camera. With 4K video capabilities, an overhauled AF system and a new 24MP APS-C sensor, I was more than eager to put the a6300 to the test.

The release of the Sony a6300 further chips away at the advantages DSLRs hold over mirrorless cameras. New sensor and AF system aside, one of the camera’s most noteworthy features is the ability to shoot an 8 fps burst with a live feed of what you are shooting (as opposed to the stop-motion playback of images typically associated with fast burst rates on mirrorless cameras). This live feed during continuous shooting, and the relatively short associated blackouts, are mirrorless firsts and should make it easier to follow the action while you shoot.

As I packed for Miami, I couldn’t help but wonder just how easy it would be to shoot a burst with the a6300 compared to say, a Canon EOS 7D (which also uses an APS-C sensor and can fire 8 fps bursts). If the image above is any indication, my experience shooting bursts with the a6300 were largely quite positive!

First night in Miami, First Impressions

The Sony a6000 was a massive hit. Not only is it the best selling mirrorless camera of all time, but also the best selling digital interchangeable lens camera of all time. These two bits of information were presented to a group of about 30 journalists (including myself) at the start of our first evening in Miami. And regardless of what parameters were considered when the above conclusions were drawn, one thing is clear: Sony anticipates the a6300 to be another top seller.

In terms of design, the body of the a6300 looks nearly identical to its predecessor. But there are several small, yet important changes to the construction. What was previously an assignable AE-Lock button on the back of the a6000 is now a button/toggle combination, allowing for twice the amount of customization. By default, the two positions are AF/MF and EA-Lock. The first thing I did when handed the camera was reassign these two positions to be ‘AF On’ and ‘Eye AF’ (more on that later). 

The other notable change is in the material which the a6300 is constructed. Sony moved away from the shiny plastic of the a6000 to magnesium alloy on the a6300, with a finish reminiscent of the a7R II’s construction. The new material certainly adds a more robust-feeling quality to the camera. That said, I suspect it still wouldn’t handle a fall from several feet with much grace.

The a6300 features a new JPEG engine compared to the a6000. ISO 100, 1/320 sec at F5.6. Shot using the Sony FE 70-200mm F4 G OSS at 101mm.

One easily overlooked improvement on the a6300 is the ease of selecting one’s AF point. I like to shoot using the flexible spot. Previously, on the a6000, to move my spot around I needed to first hit the center button on the back click wheel, before hitting any of the direction keys. On the a6300, the center button functions as a toggle. By default a press of one of the direction keys brings up its assigned function. But hit the center button once and the direction keys function as your AF point selector. Whichever function you have the direction keys set to, your choice is sticky (unlike on the a6000), so even if you turn off the camera or pop into the menu, it will default to the last function set (unless you change the mode).

Shooting bursts

The a6300 can shoot bursts as fast as 11 fps with AF or 8 fps with both AF and a live feed. As I mentioned, going into this shooting excursion, what I was most curious about was how easy it would be to follow very fast moving action with the a6300 while firing a burst at 8 fps. I’ve shot sports, both extreme and team, on DSLRs over the years. And while I thoroughly embrace mirrorless cameras and the benefits they offer over DSLRs, I’ve found them difficult to use for sports photography.

Fortunately, the very first shooting event in Miami was at a wakeboard park, the perfect place to put burst shooting and the a6300’s 425-point on-sensor phase-detection AF system to the test.

In the video below, I rigged a Sony RX100 IV up to shoot 120 fps video through the EVF of the Sony a6300 while I fired several series of bursts (incidentally, the a6300 can refresh the EVF at 120 fps as well, bringing it closer to an OVF experience). This should give you an idea of just how easy it was to follow the action, especially considering the fact that I was framing the subject using the RX100 IV’s LCD as I rolled video.

The above video demonstrates the a6300’s live feed during 8 fps shooting, shot through the EVF.

Of course, once I ditched the RX100 IV rig and used the a6300 with the EVF to my eye, I found following the action to be even easier. Nearly as easy as following action with a DSLR, except for the fact that in bright daylight, as a glasses-wearer, even the nicest EVF’s can be difficult for me to keep an eye to for an extended period of time (as is often necessary when shooting sports or action).

Still, the a6300’s live feed during burst shooting is a massive improvement over every other mirrrorless camera I’ve ever used.

Autofocus

Though it took some time to figure out the best AF settings for wakeboarding, I was largely impressed with the a6300’s hit rate of in-focus images at 8 fps. Sony’s subject tracking system (‘Zone’ in the video above) also meant I didn’t need to keep a tight AF point precisely over my subject: the camera automatically chose appropriate points to maintain focus on my subject.

I found keeping my focus area set to either the ‘Flexible Spot’ (Medium or Large) or ‘Zone’ gave me the best results. With the camera set to Continuous AF, I simply panned and kept my AF point or cluster of points over the subject. The larger AF areas gave me some room for error in placement, and the camera took care of the rest by automatically picking appropriate AF points within my selected region to stay on the subject.

Assuming I locked focus at the beginning of the burst, which the a6300 often did, my hit rate was good. I also briefly tried using lock-on AF, where the camera uses a more sophisticated pattern matching system to identify and track a subject around the frame. In my few attempts, the a6300 did a decent job maintaining focus while also tracking wakeboarders through a relatively simple scene (though I wonder whether the a6300’s pattern matching system is specific enough for more complicated scenarios, a problem we’ve encountered before).

Eye AF is very useful for portraiture. This image was shot the second day of the press excursion, when I was concentrated on field testing the G Master 85mm F1.4 and 24-70mm F2.8 lens. ISO 400, 1/50 sec at F2.8. Shot using the Sony FE 24-70mm F2.8 G Master lens at 24mm.

As I mentioned earlier, one of the very first things I did when handed the camera was re-assign the AF/MF button to ‘Eye AF’ and the ‘AEL’ button to ‘AF On’. A small toggle on the back of the camera lets you choose which of the two functions the button executes. So when I had a human subject, like in the portrait above, I simply flipped the toggle to ‘Eye AF’ and held the button down until the a6300 locked focus on the model’s eyes (Eye AF – and the camera in general – is far more useful in AF-C, by the way). For non-human subjects, I flipped the switch back to ‘AF On’ and went back to shooting with my selected AF point or area.

When using E-mount lenses, Eye AF performed extremely well, on par with the excellent performance we observed from the Sony a7R II. And like the a7R II, in scenes with multiple faces, you can simply hold down the Eye AF button while placing your selected AF point over your desired subject to prioritize that person (you can even recompose freely if you’re in AF-C). However it is worth noting that Eye AF performance (ability to find an eye) and accuracy on the a6300 seemed to drop slightly when I tested it using the 85mm F1.4 G Master lens.

Low light frustrations (saved by the G Master)

 G Master flex: ISO 1000, 1/400 sec at F1.8. Shot using the Sony FE 85mm F1.4 G Master lens.

Our second stop on the shooting excursion was an indoor parkour park. Parkour, for those who do not know, is in a sense, urban acrobatics — it requires an incredible amount of gymnastic ability and physical strength and has a dare-devil, DIY-like culture surrounding it.

The park consisted of all sorts of colorful obstacles, foam pits, ramps and gymnastic bars. Unfortunately, being indoors, I had to crank my ISO very high to have a fast enough shutter to capture the action. And because the only E-Mount (non-FE) lens Sony issued each journalist was a 16-70mm F4, shooting wide open still was not all that fast.

Most of what I shot using the 16-70mm was up at ISO 6400 or beyond and frankly, looked pretty noisy and unappealing. Also a problem: Despite cranking the ISO, I still was not quite getting shutter speeds fast enough to freeze the action. So about half way through the shoot, I switched out the 16-70mm for the much faster 85mm F1.4 G Master (which is an FE mount lens). This not only gave me the ability to bring my ISO back down (by opening the lens up), but allowed me to change my perspective on what was happening in front of me. Instead of shooting wide shots of peak action, I instead looked for details.

In retrospect, I wish I had pushed my ISO just a bit further when shooting with the 85mm G Master and stopped down the lens just a little more (especially in the image above). But had it not been for the fast aperture of the G Master 85mm F1.4, I’m not sure I would have gotten any usable action shots at the parkour park.

As an everyday shooter

Tilt and shoot: I much prefer tilting LCD’s to fully articulating ones. It’s a matter of personal taste and one that video shooter may disagree with. But as a primarily stills-shooter, tilting LCD’s are far more unobtrusive as they don’t flip out to the side, doubling the camera width and potentially drawing attention. ISO 6400, 1/160 sec at F2. Shot using the Sony Carl Zeiss Sonnar T* E 24mm F1.8 ZA lens.

As day turned to night, I swapped out the the 16-70mm F4 for a 24mm F1.8 (which I forgot to bring to the parkour park). Our final destination for the evening: Miami’s Little Haiti.

Here I wandered around using the a6300 as I would a personal camera, and by that I mean: not trying to test features, but simply looking for interesting compositions and using the camera to the best of my abilities). With the 24mm affixed, the a6300 is a rather nice size, and weighs a mere 626 grams, which is about the same as an a7R II, body only. 

While the Sony a6300 is not nearly as lovely to look at or hold as an Olympus PEN-F or Fujifilm X-E2S, it easily out specs both those cameras in every capacity. And honestly, I’ve been hard on Sony design in the past, but the a6300 is no slouch. Between the new customizable toggle on back, the function menu and ample additional customizable buttons, it’s pretty easy to set up the a6300 exactly to your liking. And frankly, having a camera that people aren’t going to “oooh and ahhh” at might mean an easier time getting the shot.

Of course, a front-facing control dial would make a world of difference (the a6300, like the a6000, has a rear control dial as well as a control wheel on the back of the body, but no control dial on front). Furthermore, especially considering the camera’s video-centric features, a touchscreen would be hugely useful. As would the ability to customize buttons for stills vs. video shooting (certain stills functions, like Eye AF or E-Shutter or Drive, are unavailable when shooting movies, so if you’ve assigned buttons to such functions, they all become literally useless in video).

Still, it didn’t take me long to completely forget about what camera I was shooting, and just take pictures. I think this fact is more telling than anything else I experienced in regard to the a6300. Too often cameras can overwhelm a user with options and settings. But a day of shooting with the a6300 got me comfortable enough with the camera, that by evening, we were humming along in unison, each doing our part to make the best image possible, without stepping on each others’ toes. 

As a video shooter

Video quality from the Sony a6300 looks quite good. I’m especially eager to further try out the camera’s continuous AF during video capture (be sure to select ‘4K’ quality in YouTube for best viewing).

I didn’t shoot a ton of video over the course of my time in Miami, but I did shoot a few low light clips in Little Haiti. After all, the a6300 can shoot 4K video with full pixel readout and no binning. What does that mean exactly? Good quality, very good quality.

Furthermore, the a6300 offers ample tools to assist in video-making. Like recent a7 cameras, the a6300 offers three AF Drive speed options (slow to fast), and a toggle to adjust AF tracking sensitivity during video shooting. While I did not mess around with subject tracking during video, which still requires you use the antiquated ‘Center Lock-on AF’ function (seriously, c’mon Sony), I did try using face detect during video capture, as well as continuous AF. In both cases, I had the AF Drive speed set to normal, and found the a6300 able to lock focus in a smooth manner, without hunting.

Final thoughts

It’s pretty clear that Sony set out to create a future-proof camera in the a6300, one who’s specs will likely look impressive, even two years down the road. The camera has a lot of fire power, both in the AF and video departments, and initial impressions indicate that everything works as it should. Which is to say, the a6300 is a really impressive little camera.

It’s certainly not going to turn any heads with it looks, but it should give you everything you need to instead turn heads with your images. Which for most, is a much more worthwhile goal.

Making a splash:  ISO 320, 1/12500 sec, F5.6. Shot using the Sony FE 70-200mm F4 G OSS at 200mm.

Density Sensor: Real-Time Data Shows Which Places are Packed

10 Aug

[ By WebUrbanist in Gadgets & Geekery & Technology. ]

density location sensor

Online reviews indicate how popular your favorite place is in general, but cannot tell you whether now is a good time to drop by or if you may be stuck in a crowd or waiting in line – this is where the Density Sensor comes into play.

density sensor tracking

No need to resort to complex spatial mapping or real-time video sensors with this gadget, a people-counting device that simply tracks passages through doors (attached to the frame). Some more obvious applications include specific bars, restaurants, coffee shops and other businesses that have time-of-day and day-of-week cycles to contend with, but the same data can also help you pick the DMV or grocery store with the shortest line.

density incoming outgoing people

In turn, businesses can choose what data to share with customers and what to keep for optimization purposes, offering discounts during less busy times or adjusting when to open and close. Compared to non-networked break-beam technology or real-time surveillance cameras, there is no need to wait for data or face privacy concerns.

density sensor box

Of course, up-to-the-minute incoming and outgoing traffic are just a starting point – architecture firms, for instance, could use extended datasets to anonymously track customer or employee flows through a building and use that data to optimize going forward, shaping extensions or remodels. Ultimately, one could imagine this system being replaced by more detailed heat-mapped trackers keeping tabs on entire spaces, but for now this is a cheap solution to a long-standing problem.
