Night vision on CCTV can be a very powerful tool in monitoring after dark, and their technology is far more complex than most people give it credit for.
Two Main Night Vision Types
Infrared (IR) cameras use special LED’s to create a black and white image in complete darkness. Other Colour Night Vision Cameras use what is known as a “Starlight” image and have a very large sensor to collect as much ambient light (from the moon, stars and street lights) as possible, this creates a colour image.
What IR Range Figures Actually Mean
A typical driveway would be covered using an IR range of 30m, but open car parks would require an IR range of 50m or more. For more on this, take a look at //apmfireandsecurity.com/cctv-installation/cctv-installation-worcester/.
How Surfaces Affect Night Images
A camera positioned to avoid highly reflective surfaces such as white backgrounds or wet tarmac can help improve image quality by reducing the chance of IR washout. CCTV Worcester is worth getting right.
Positioning Cameras for Best Night Coverage
Make sure that the IR LEDs from your camera are not obstructed by branches, gutters, signs etc. overhanging roof edges and banks of walls and creating shadow.
Getting the right night vision specification for your CCTV cameras makes all the difference to how much you can see of what’s going on after dark.
