If the CCTV cameras are going outside your home in Elk Grove CA – you do
Most security cameras without night vision can not see in low light conditions or in total darkness.
So if your security cameras are outside and the lighting conditions are not very good or there is no lighting at all and you want to see at night – you need night vision.
With the Infrared lighting in the cameras, the camera will light up the space with infrared and you can still see. when the IR comes on the image will go to black and white instead of color – but you will still be able to see. If the cameras are HD or better you will still be able to see clearly and identify people objects and cars. Night vision security cameras are a necessity and must have – if you are getting a security cameras system.
