Surveillance System - Camera controller, TV set and VCR.
(click any image to enlarge)
The camera controller I adapted to work with the cameras I wanted, not the cheap cameras that were supposed to be bought with it. The TV was surplus from some previous project, the VCR I got off of Craigslist for $10.00. The whole system cost less than $400. It has three color cameras with motion detectors, records sound, has night vision and a PA system through each camera.
There are two cameras mounted above the garage door at the top of that half circle vent.
Protective box I built after cameras vandalized and cables were cut. I also mounted the next box and cameras way above "reach" height at about 9 feet.
This camera used to be outside in the eaves looking back at my front door. After it was vandalized and torn down I mounted it inside the security screen door.
I drilled a hole in the heavy steel screen just big enough for the camera lens and mounted it with restraining wire. That cable routes through the house via the cold air intake for the furnace, through the cold air side of the furnance and out to the camera controller in the garage.
That camera is nearly invisible.
The flash makes it look more visible because the paint around the hole is still new. People have stood at the door and not noticed it.
This project is still in progress as the infrared light sources in the cameras are too weak for adequate night time illumination. I may have to build those as what is on the market that I am aware of is generally pretty expensive.
