Consumer Webcams With High-Quality Sensors? 218
xmas2003 writes "Since 2005, I've had a live webcam watching my grass grow — another is currently watching a bird nest on my front door — five babies! While I appreciate the 802.11g wireless and Pan/Tilt/Zoom (10x optical) of the five-year-old D-Link DCS-6620g, it has issues, especially image quality. I've investigated getting a new webcam, but except for high-end/security-related gear from companies such as Axis, there doesn't seem to be much improvement in the consumer space, as most offerings are just cheaper and USB-connected for tethered video conferencing, etc." So where, the reader wants to know, are the high-quality, reasonably affordable webcams? (Read on below.)
"I have an 18 Megapixel Canon 7D DSLR that shoots gorgeous 1920x1080x30p hi-def video. While I don't expect that in a consumer webcam, their recently released T2i uses the same chip and sells for $800. And heck, point-n-shoots are a couple of hundred bucks, and now many cell phones have cameras built in, so there're plenty of low-power, speedy CPUs in small packages these days to handle the signal processing. So why hasn't someone taken a sensor with good image quality, downsized to around 1024x768, and put it in a PTZ webcam package with 802.11n wireless for around $500?" Even if it's not that exact combination, what are the best options going these days for high-resolution webcams?

Re:Great question (Score:5, Informative)
Having just had my house broken into ~2 weeks ago and spending most of the past two weeks researching good-but-affordable security cams as a result, here's a bit of what I learned (and bought):
The best-yet-cheap hi-res IP camera I've found is the Compro IP70 (available in the US from Directron, widely available elsewhere in the English-speaking world and a big chunk of Europe).
* The good: 1280x1024 resolution and 1/3" CMOS sensor, awesome low-light performance, onboard microSD card for persistent storage of snapshots triggered by motion or inputs. Dual codecs, so you can have it simultaneously grabbing 1280x1024@15fps for snapshots or web viewing, as well as 320x240 or 640x480 (among others) for viewing on your Android phone/iPhone/other phone. It explicitly supports MJPEG, h.264, and MPEG-4, plus 3GPP (apparently, this means it might work on Java ME MIDP phones and Symbian).
* The bad: mediocre room-light performance with color that's utterly dire if you have the IR activated, and once an event triggers a snapshot (that can be saved to SD, FTP'ed, and/or emailed), it can't take the next pic for ~4 seconds.
* The mitigating: telnet ${ip} to get a real, honest to god root shell complete with busybox. Very little public documentation, but looks almost shockingly straightforward to figure out what's going on, and maybe even replace the onboard apps with my own. According to 'top', the camera has at least 50-100mb free ram running normally, so implementing a burstmode that can grab a bunch of shots to ram once triggered, then upload/save them to persistent storage later shouldn't be too hard. One big tip if you get this cam: "low light" mode != "IR mode" -- low light mode cuts the framerate to interpolate more gray and average out the noise. The problem is, it utterly ruins the camera's ability to take meaningful event-triggered snapshots. So, if I could request just one improvement to it, it would be, "implement a burst mode whereby the camera will (optionally) take 1-4 pics immediately, turn off low-light mode, then take 1-N pics... saving them to a ramdrive, with another daemon pushing them to persistent storage in the background. If nothing else, this camera has serious potential as a fun embedded linux box with onboard USB (the optional wifi is USB), two isolated inputs, and one isolated output, plus 10/100 ethernet. I bought one so far.
* Other details: it's not PTZ, and it's not weatherproof. It's also pretty huge (~5" x 5" viewed head on), so think twice before planning to stick it somewhere aesthetically obvious in your house.
The IP70 has a baby brother with the same resolution, but without the IR called the IP60 for about $40 less (also available at Directron). I haven't used it, I'm just mentioning it to be complete. Officially it has no IR capabilities, but to some extent just about all CMOS cameras seem to be at least slightly IR-sensitive.
For cheap PTZ Linux-based fun, you can't beat the Foscam FI8908W. Their official US distributor is foscam.us, and they're readily available for less than a hundred bucks on eBay (a non-wireless variant exists; it's rare, but about $10 less). Just be careful and make sure the seller LITERALLY specifies "Foscam FI8908W", as opposed to "Foscam-Type" or just shows a pic. There are a LOT of fakes on eBay. I haven't seen them side by side, but from what I understand, the fakes are basically the same camera body and electronics, bought from the same ODM, but have different firmware, and apparently tend to ship with visibly lower-quality lenses. Apparently, some can be reflashed with Foscam firmware, some will get bricked if you do.
Foscam cameras only do 640x480@30fps with MJPEG, but they make up for it by being one of the only cheap IP cameras that doesn't need Internet Explorer to work. They're also very hackable, with several individuals who've made lots of public progress documenting their hardware, bootloaders, and onboard i/o ports (they support 1 in and 1 out, plus JTAG and a few other ports as well.

I forgot to mention -- don't put ANY of these cameras anyplace where you wouldn't mind being viewed by members of the internet-using public unless they're sitting behind a bastion-host firewall/proxy and/or you have a way to physically power them down when you're at home, because their security is largely ceremonial, and trivially easy to bypass if you know what you're doing.
My own setup: my new cameras sit on their own network. The cameras are all powered through X-10 appliance modules, and connect to their own wireless router/access point (itself plugged into an X-10 appliance module). When my security system (Elk M1G) goes into 'away' mode, it cycles through them all twice and sends their 'on' codes once per cycle. When my security system gets disarmed (and hasn't been set off), it sends the 'all off' code to power them down. For now, the second access point is connected via UTP to my main router, with the relevant ports forwarded and double NAT, but at some point over the next few weeks, I'm going to repurpose an old laptop with Debian and use it as both a persistent storage drive and bastion host firewall/proxy (so there will literally be no way to connect directly the cameras from the internet, and so I can use SSL). I'm not thrilled about the wifi security, but it's mitigated by the fact that they're only physically powered up when I'm not at home.

Foscam's CGI-based web API (for integrating its video into your own app). It's far from perfect, but it's several orders of magnitude better than anything I've seen from companies like D-Link, Linksys, etc. In any case, it beats trying to reverse-engineer what some buggy ActiveX plugin is doing by sniffing the traffic with Wireshark. For comparison, my old PTZ camera is a D-Link DCS5300-W. Its bundled software was quite dire compared to the software that came with my new Compro IP70 and my Foscam FI8988W cameras, and the only thing the D-Link camera has a straightforward means of doing is grabbing a single 320x240 pic (no way to grab 640x480 from it), and I spent HOURS hunting for the elusive URL online.

If you have an Android phone, there's one app I know of for viewing many IP cameras: IP Cam Viewer by Robert Chou. Search for it in Android Market (I think it can also be downloaded directly if you're in a country without access to Android Market).
There are also lots of low-cost thirdparty IP camera apps -- viewers, spoolers, etc. Don't be afraid to ditch the app(s) that came with your camera(s), especially if it has a known public API and/or implements known standards.
If you're planning more than a half-dozen cameras (especially if you can easily run new wires for them), you might be better off with a proper security DVR -- you'll be able to use smaller cameras, and pay about half as much for them.
The cheapest web-accessible host I've found is the Aviosys 9100A (roughly 85 bucks online, including from Amazon). It can host 4 cameras and one mic. HOWEVER, I believe it multiplexes them, so you can only watch one at a time. However, I think it can iterate through your cameras, capture a frame from each, and show them all at once in a single grid if you'd like. In any case, if you're looking for a quick & dirty way to get 4 conventional cameras online, this is probably your best bet. If it had an onboard (micro/mini)SD slot, I probably would have bought one of these, too.
Aviosys also has some interesting "Kameras" that do high-res (like the Compro IP60/IP70), but were more expensive and seemed to do a bit less than Compro's. Still, they might be worth investigating, too.
For small, cheap, and cute, the prize goes to the "IP510" camera (sold online under lots of different names and model numbers... IP-510 from buy.com, IP-400 from dealextreme.com). Alex Kuklin has some good info about it on his blog (kuklin.ru), including the

Get a generic UVC 2MP webcam and a long USB cord (Score:5, Informative)
Not completely appropo, but sometimes you can find what you're looking for by trying out the not-so-obvious solution.
First, go to your local computer store and get a few generic UVC webcams.
While you're there get a few long USB extension cords. You can get an active one that will let you put your camera a few hundred yards away if you like, or a passive one that will get you to thirty or forty feet.
Now go home and plug in all your cameras, one at a time. You can plug in as many as you have USB ports, and, don't worry, no drivers needed.
For Windows, visit this site to download the "MJPEG Surveillance" program: http://www.brooksyounce.com/ [brooksyounce.com]. Install it and run "MJPEG Recorder," click the right mouse button, and choose "Add New DirectX Camera." This program will let you adjust most of your camera's parameters including frame rate, and even motion detection and how long to record after motion stops. Jack up the resolution to the highest your camera will support since you're not going to want to record full-motion video in a surveillance situation. Be sure to set the JPEG quality to an acceptable level and put a time stamp in the corner, too, that you can read and won't get smudged by the JPEG compression.
A couple of gigabytes of free space is more than enough to record days of 1280x800 at 85% JPEG quality and 1 FPS. Experiment. The motion detection is key.
For example, at my local Micro Center, you can get a typical, generic UVC 1280x800 webcam for $25 or less. Try the WinBook WB-7144 HD Webcam 2-Pack for $40 or $25 for just one camera. In any case you should not pay more than $25 for a UVC webcam. These cheap units do 1280x800 at 30 frames per second and have autofocus, too, which is unbelievable at this price point. For discretion you may wish to disable the LEDs by disassembling the camera (they pop apart after unscrewing the base) and with a needle-nose pliers remove the two LEDs.
The quality is good for daylight, and rather grainy at nighttime. At these prices, experiment and have fun!!

In all seriousnessity, check out the Zonet ZVC7630W [google.com] if 640x480 meets your needs. It runs an embedded Linux kernel with Busybox, supports LAN/WiFi/USB sticks for recording, MJPEG streaming, and has some nifty motion trigger features.
I use a few of these for security cameras and they're pretty easy to weather proof with some caulk and tupperware. My one big complaint however (which might be a showstopper for many on ./) is the built in web features such as 2-way talk require Internet Exploder. It utilizes an ActiveX applet that I haven't been able to get around.
Mobotix over Axis (Score:4, Informative)
Mobotix is by far the most expensive, but Mobotix has been the most reliable for me. Axis was my 2nd favorite, but I have nothing but lockup problems with Axis cameras requiring the cameras be scripted to reboot every 24 hours.
Folks have touched on a few subjects--wireless is convenient, but such a bandwidth hog. Setup a small office with two wireless parking lot cams. The folks in the office used wireless laptops. None of the laptops could get better than 1.5mbps transfers when the wireless cameras were on. Wired the cameras and everyone was happy. The FPS on the cameras improved dramatically and the four or five folks in the office had speedy internet once again.
Another thing folks touched on--picture quality. Look for a camera with a changeable lens. If you want be able to read a license plate or recognize a face at 25' to 50'--you are going to need a nice lens. Even more so if you want to be able to read the license plate on a moving car at night.

Resolution != Quality (Score:3, Insightful)
The best sensor in the world won't do jack squat for you if you have crap-tastic optics. For pro-am digital photography the lenses are the limiting factor these days, the sensors are more than good enough. And it's not likely you're going to find a webcam with decent glass, sorry. For that form factor (teeny tiny camera) you're not going to get good quality or low light performance.

At least some of the Android phones do WiFi, so your "large monthly fee" doesn't have to be any larger than what you already pay for Internet (as long as you've got a WiFi router). Furthermore, you can get them on e-bay without a data plan for about half of what GPP claimed, so even the initial outlay isn't that bad (a coworker did that a few days after I bought my Hero).

> So why hasn't someone taken a sensor with good image quality, downsized to around 1024x768, and put it in a PTZ webcam package with 802.11n wireless for around $500?
They have. Compro (http://www.comprousa.com/en/product/ip540/ip540.html) makes a few, though they don't appear to have reached the US yet. I saw them for around AU$340 at Directron's Australian site.
However, there's a reason why resolution for IP webcams has been relatively slow to increase: light sensitivity and cost. If you stick with CMOS for cost-savings, as a general rule a 1/4" sensor that does 640x480 will output better-quality video in low light than a 1/4" sensor that's 1280x720/960/1024. Also, as the sensor size shrinks, the impact of lens quality and mechanical build increases. That's why 99% of cheap webcams and ip cameras use 1/4" and 1/3" CMOS. It's a sweet spot that's small enough to keep the chip cost down, but large enough to let them get away with sloppy build quality and less than ideal lens designs.
I own one of Compro's cameras (the IP70). It's nice, and it was dirt cheap all things considered ($120 for 1280x1024 resolution), but its "room light" sensitivity is piss poor unless I fall back on its infrared capabilities (which do nasty things to the colors, but work miracles on its ability to effectively produce video under low-light conditions). There's a good reason why all the low-cost cameras have suddenly discovered nightvision-religion: CMOS sensors are actually better at sensing IR than they are at sensing visible light. In fact, until recently, the biggest problem faced by designers of CMOS cameras was how to effectively block infrared light and keep it away from the sensor. It wasn't until someone, somewhere, got the bright idea of letting some of that IR through, and interpreting it as a luminance channel, in a way that was relatively compatible with color video, that it suddenly became useful.
IMHO, an ideal enhancement to the next generation of CMOS cameras would be the ability to sense visible light and near-IR, but keep the IR channel's data separate in the output file. That way, you could rely on the visible light when possible, but enhance it with data from the infrared channel after the fact when necessary, instead of having to make that decision beforehand and live with its consequences forever.
Actually, that reminds me of something else I learned over the weekend: CMOS cameras *LOVE* halogen lights. I had my stairs lit up like a stadium with compact fluorescent lights, and it barely made a difference to the image quality I got from my camera. Then, I read a suggestion from someone online to try replacing one of the 23-watt CFL bulbs with a 40-watt halogen bulb. Good god, it was literally a night and day difference. Reds are badly desaturated (things that reflect red light also tend to reflect near IR, and halogen bulbs emit half their energy as IR), but the detail is razor-sharp. Basically, halogen bulbs give IR-loving CMOS sensors more of the light they crave. Energy-efficient CFL bulbs emit almost no IR, so they starve its sensors. Even though the 40-watt halogen bulb is only about half as (visibly) bright as the 23-watt CFL, it's pumping out more IR than dozens and dozens of discrete camera-mounted IR LEDs.
