The World’s Best Low Light CCTV Camera Performance
The Best Low Light CCTV Cameras with the Best Low Light Analytics Software
One of our main technology strengths is our advanced low light CCTV camera technology and our low light CCTV Video Content Analytics (VCA) software, called Viseum Intelligent Virtual Operator or Viseum iVOS CCTV monitoring software. This provides outdoor low light surveillance camera CCTV security and key to this is the use of an advanced algorithm which continuously measures and adapts to constantly varying ambient light. This is highly effective for low light security, when the naked eye finds it difficult to see. The examples that follow show how well activity is detected in such low light conditions:
This example uses a low bandwidth 3G connection and Viseum’s Central intelligent Video Management System (CiVMS).
Viseum Outdoor Surveillance Cameras for Advanced Low Light CCTV Security
Example 1: Outdoor Surveillance Cameras – Low Light CCTV
Our strength in automated open space surveillance is enhanced through a combination of superior camera hardware optics. A popular model of our PTZ camera array uses fixed contextual view cameras with a Sony Ex-View 1/3” CCD high resolution with 570+ TV lines and an extreme low light sensitivity of 0.005 lux. This example shows that although these fixed contextual view camera images look quite bright, the time stamp on the matching close-up PTZ image shows that these conditions were in fact on a November night under standard sodium street lighting.

The limiting factor on the quality of recorded close-up identification evidence in low light is of course the PTZ camera. For installations with zero lux we specify panoramic IR illumination, but for installations with varied low light challenges we specify suitable zoom levels of our PTZ camera model and/or directional IR.
This example shows similar activity detection as the previous example, but in even lower light and at a greater distance, which is why the PTZ switched to mono. Click on each image to expand:
Example 3: Outdoor Surveillance Cameras – Low Light CCTV Camera
This identification evidence is from a field installation in London. The area on and around these public benches had been given priority surveillance by the Viseum outdoor surveillance camera system because the end user needed to clamp down on illegal street drinking in the area . The evidence provided was subsequently used to identify illegally imported beer and prosecute a local shopkeeper for supplying it. News of the success of this installation was broadcast in a TV interview. Click on each image to expand:
Low Light CCTV Security and Surveillance Examples
Outdoor Surveillance Cameras – Low Light CCTV Camera Technical Requirements
The factor that limits the quality of low light outdoor surveillance cameras and their ability to record identification evidence in low light environments is the optical performance of the PTZ camera. Effectively, the level of light required depends on the zoom levels needed. For installations with varied low light challenges, we specify suitable PTZ models with various optical zoom levels. For installations with zero lux we specify suitable IR illumination for the site.
