Alert Security Systems

Well, you could consider that Lenny's step 2a <g>  When you put the SD card in the PC, instead of formatting, you can check for what clips are on it...should tell you if recordings were made in the timeframe you are interested in.  Also, when the camera stops recording or communicating with Alert Commander, is there a status LED lit on the camera ?

The 12 hour thing is a bit suspicious...check your router log to see if any clue there...maybe it gives the camera a different IP after 12 hours or something like that.  If so, you should be able to reserve an IP for it in the router...making it a fixed/static thing.

Siriusly,

 The only way to check the cards would be manually. As UseLessS suggested you can do this with my 2nd step. So if you have a card reader with your computer you can actually pull out the micro SD card from the back of the camera (be sure to cut the power to the camera whenever removing/replacing SD cards) then pop it into your card reader on the computer. This is a good time to do a format as well because sometimes the format command from the program won't go through if the powerline performance is low.

 Secondly, your assumption might be correct. As the camera is literally using the exisiting power lines in your house to communitcate to the router (via the homeplug bricks), any change in current (eg, an eletrical device starting up) could kick a camera with a weak connection off the network.

 Try testing the powerline performance at different times during the day to see if there are major fluctuations.

 Also as UselessS suggested, there might be something going on with the router's end. Perhaps the router's leasing of IPs is set for 12 hours. Check the IP lease on your router.
