The Head of Overt CCTV Surveillance for this Police Force also said "Viseum's technical capability is unquestionable, but we will always remember Viseum above anyone else for their main strength of listening to us to develop their innovation."

Best Low Light Security Camera

“Our Best Low Light Camera”

World’s Best Low Light Security Camera

The visual appearance of Viseum’s Panoramic Low Light Security Camera operating automatically protecting all surroundings, displays to would-be criminals that the entire site is constantly watched by many surveillance experts.

This low light security camera uses Viseum’s Central intelligent Video Management System (CiVMS) and can operate over a low bandwidth 3G connection.

Best Low Light Security Camera and Outdoor Surveillance Camera 

 

Virtual Gigapixel Low Light Security Camera

The Viseum Panoramic Security Camera has a patented multi-camera system to support environments that suffer from low light. Its starlight fixed and moving camera lenses with auto-zoom are designed to optimise the available ambient light. Also, for ultra low light or where there is no light, the area covered by Viseum’s low light Panoramic Security Camera can be illuminated using infrared or white light devices, and can be wireless and battery powered if required.

Best Low Light CCTV Analytics Software

One of our main technology strengths is our advanced low light security 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 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:

 

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 has fixed contextual view starlight cameras using Sony’s ‘starvis’ sensors, providing extreme low light sensitivity of 0.001 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.

Example 2: Outdoor Surveillance Cameras – Low Light CCTV

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 or white light illumination, but for installations with varied low light challenges we specify suitable zoom levels of our PTZ camera model and/or directional illumination.

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

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:

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 or white light illumination for the site.
