Sadly my google-fu isn't good enough, and all I came across was references to the app. However 50$/camera and an NVR for 200$... might be good for indoors or some of the doorways inside.

Comments on cameras or experience?

@alastairstevenson , where would you recommend I start for this camera? Should I fire up a new thread?

I've got the thing gutted on the table. Interestingly it has a reset switch inside, and a CF solder tab but not attached. Appears to have a dedicated connector for Serial, too (not just pads).

Responds to tFTP on 192.0.0.64/128 as well, but I can't locate firmware from it. I was going to grab the chip off and dump it if I could, as well as attach serial consoles.

Binwalk is waiting...
