Awesome stuff. I do wish they'd release a module without the bayer filter for monochrome imaging. Granted it is maybe quite a bit of work to rewrite parts of the ISP to suit a relatively niche market of monochrome sensor...

The color filter is much more closely integrated with the camera sensor than the IR filter was. I don't know for sure, but I suspect it can't be removed without risking damage to the sensor.

I've been looking into home security lately and with the more expensive camera-kits (say $2k+)... I've been wondering if a de-centralized raspberry-pi setup might be so much better. And with 8mp I think I should start a POC, right?

There's a lot of competition in this space. If you want to do DIY for kicks, then of course feel free to, but items like this are pretty tempting for those of us without much free time:

Siren, two way audio, camera, motion sensor, etc. I've been eyeballing this for some time. Might get it before I go on my next trip.

A pet door?

Cat-specific food bowls :-)

I was researching this a few months ago, but gave up upon the cat facial recognition. The best I could find for the raspberry pi was opencv haar filters for humans, and that was just detecting if a face was present in the video frame. I'm curious, how are you planning on doing cat facial detection for this?

maybe he has a white cat and a black cat... but I would probably use RFID chips in their collar.

There are a few projects out there [0][1] that make it fairly simple to set up a motion detection capable solution with a simple USB webcam. I'm currently waiting on a cheap infrared camera from China ($4!) for use with my Pi, but I've done testing with an older Logitech HD camera and have had excellent results.

If you don't mind, could you please post a link to the $4 IR camera?

I picked one up on eBay [0] that is currently in transit to my apartment. Manual focus, somewhat garish looking and with probably crummy resolution, but I'm willing to try it for $4.

There are a large number of similar cameras on the market that ship from China/Hong Kong on eBay. YMMV, but if you've got a few bucks and are willing to wait, it may be worthwhile (depending on your use).

I would like to see a round cable version. I know this may not fit the design ethos, but I've had projects that I really wanted to use the Pi+camera and couldn't because of camera positioning (a 1m round cable would have worked) .

The connection standard they used is really meant for use in a mobile phone, with a 3cm ribbon going from the board to the camera. I've seen CSI cables close to a meter for sale, but I'm not sure how reliably they work. The sibling post about the HDMI cable seems like your best bet.

The USB camera idea would work too, but it wouldn't have the same performance characteristics as the PiCam (The Pi's USB implementation is terrible, as far as throughput and CPU load).

That's what I'm trying first. RFID range is an issue, however. The electronics for this is easy, the problem is that I suck at carpentry.

The cats in question are pretty different (one black, one orange), so discrimination in visible light is easy. Not sure about IR yet.
