cheap "wildlife camera"
 

Is there a cheaper version of this?

Digital Motion Detection Camera - National Geographic Store

One of my 3 cats has taken to "missing" the litter box. I want to find out which one it is. I want the camera to take snaps or short vids whenever motion is sensed, either via PIR or digital video motion detection. I want it stored on a memory card. Or a version that transmits via WiFi.

missing or avoiding?

cat UTIs and insufficient quantity of litter boxes or just general cat stress can cause litter avoidance and random pee.

you can do this easily with a webcam and laptop...


sounds like someone has a UTI.

If a webcam is too suspicious, there might be #808 cameras with motion detection.

I say might, because I only see Alibaba.com as an indication what might be available on eBay.

Or this
Water"proof" and Night vision seems to be what you need around a litter box :)

You can DIY it.

It's #2 that misses the mark, not #1.......

Something is eating the bushes in the front of my house. I've thought about picking up something like this.

Wildgame Innovations Flash 4 4.0 Megapixel Digital Game Camera | Bass Pro Shops

That's exactly what I would get. That brand is kind of a benchmark budget manufacturer in the hunting world... cannot go wrong for indoor or light outdoor work.

OTOH... why not just get an IP cam... they all come with motion detection software and usually have an infrared LED setup for nitevision. You just plug it into the wall, hook it to your wifi, and set up the software on your PC... plus you can watch on your phone.

Everybody should have one of these up and running in their house day and night... just for the lolz:

But like Braineak said, ANY webcam already does this. I'm sure there's some free software from CNET you can download that's better than whatever proprietary crap came with your camera.
