A 12 volt battery pack with a built in switch was chosen to power both the camera and the infrared LED array. Having 12 series connected LEDs, each requiring 1.2 volts, made this battery pack the perfect choice, and the camera also require 12 volts DC to operate. You could probably hack into the camcorder and pull the needed power right from the built in rechargeable battery, but this might be difficult as the lithium pack will probably have a lower voltage than necessary to operate an external camera. The camera and infrared illuminator will run for hours off of this small 1 amp hour 12 volt battery pack.

To get the camcorder to accept the external camera as the default video input, I had to jump into the onscreen menu system (Figure 23) and choose "AV Input", which turned off the cameras built in color imaging system and replaced it with the signal coming from the black and white spy camera. Some cameras will automatically switch to the external input once a sync signal is detected, but you may have to play around in the menus to get your camera to switch to the external camera. Oddly, my camera only records the external source when in "playback mode", which makes it act like a mini VCR.
