As infrared LED array came up with technology and state of the art electronic and optical components that will bring us the ultimate in day and night vision efficiency and high power infrared output.
This can be started by calculating how much infrared radiation you will need in order to light your scene that would be the focal range of your camera since details are lost on most security cameras. With the use of Dremel tool or small bench top grinder, grind down one side of the LEDs slightly and then pack them down to a smaller area. The builder used 19 by 13 LEDs for a total of 247 LEDs, to fit into the inside of a halogen work light.
When the LED array is wired, simply run copper wire along the columns to create the parallel wiring connection for each series chain. The power adapter can be plugged into an AC socket just as it was before modification and cut the AC wiring inside the light enclosure and affixed it directly to the AC power adapter. Materials such as dark tinted glass will also work to conceal an LED array.
