This mornings project is for those of you that are into night vision equipment and perimeter security issues. As some of you know I have IR camera's set up on all 4 sides of my house which are connected with all of the TVs in the rooms and bunker. Through a video sequencer unit that was wired in when we built the home, a multiplexed video feed can be set to manual or automatic, which then switches cameras every few seconds or so and give me a view of the outside even in the dark. One of the problems I have is to know if someone is in the perimeter beyond the 50' camera invisible IR light range. I have come up with a modified battery operated motion detector that can be located further out in the yard and will only come on when motion is detected.
