With all of the components working together perfectly from the 6 volt battery pack, I found a suitable black box to create a self contained unit that could be sent into the battlezone. The motion sensor was glued to the top of the enclosure as shown in Figure 18, with a hold drilled out so that the PIR window could see the outside world. The Fresnel lens part would then be glued over the box lid to expand the field of view. The battery and relay board were also mounted into the small plastic box to that the unit would be a fully functioning motion trigger system that could be plugged into the hacked digital camera or any other device I felt like operating under motion detected control.

The completed motion activated camera is shown in Figure 19, waiting to capture in high detail the next person who dares to wander into my livingroom. As a security system, this project works very well, especially when a high level of detail is necessary. On a fresh charge, the camera can run for hours, snapping photos until the batteries are dead or until the memory card is full.



This system also works well in nature photography, where a stealthy setup is needed in order to capture some elusive creature or one that you don't want to be anywhere near due to danger. I also found this project useful when I wanted several group photos that I was supposed to be included in and did not feel like fiddling around with the single self timer on the camera. With this system, you just turn it on and the camera will keep on acting like your personal paparazzi as long as something is moving in its field of view!
