[Sibtain]

Re: thermal imaging

A number of IR sensors are available in the market that can be used. I have used one such chinese made IR sensor, which uses 220V ac and gives out a 220V ac signal as output once some movement is detected. This signal can be used to activate any code sequence from the 89C51 that you wish to use..
I hope this would be of help to you.

Re: thermal imaging

One simple approach to this issue is to use two, or more, standard miniature security IR sensors, which are off-the-shelf items and therefore inexpensive, and position them in such a way that each covers certain section of room ..
Even if they overlap a little bit, the microcontroller can easily "decide" how to re-position your video camera ..
