2) What type of night vision capability becomes necessary? A normal packaged color security camera could have a night vision selection of between 15 and 50 feet. High powered night vision cameras can have a range of 150 feet. SeriousSecurity CCTV The main factor of determining the night time vision range is how many infrared LED's on the camera.
