We did camera at the front/rear door entrance which turn on with motion/doorbell ringing. I have attic access to the sides of our house so I will run wire for cameras on each corner of the house and one for the little one's room as well. Cameras for indoors aren't bad and not that expensive to get a good image. You can pay decent money for a camera that you can see images on but if you want a camera that is detailed and per say can identify a burglar or what not they are very expensive and you will pay dearly. Exterior cameras are awhole different ball game and the high end cameras are definitely not be in the $1,600 price quote received.

Hope that helps!

I have a good bit of experience dealing with the security cameras for our gated community. DH is on the Board and has the program on his computer, so I'm the one that gets to update, etc. For you to be able to see details at night, you'll either need excellent lighting or an infrared camera. If you have one entrance/exit, you could zero in on the exit to catch car tags.

We opted for an 8 camera system with 8 channel DVR. The 8 cameras have 700 TVL Sony CCDs. The system has remote access, LCD monitor and additional runs to televisions in the family room and master BR. Total cost was $2500.
