Night Vision CCTV
Criminals love the dark and approximately two-thirds (63.2 percent) of rapes/sexual assaults and 71.7 percent of motor vehicle thefts occur at night. Night vision CCTV surveillance cameras can protect your company, your home and your property in even the darkest of conditions. There are three types of night vision cameras to choose from – infrared, low light and thermal.
Infrared Night Vision Cameras
Infrared night vision cameras (sometime know as IR cameras) have sensors that can detect the faintest amount of reflected light in the infrared spectrum. They use these sensors to produce a black and white image, as you can see below. Most camera manufacturers offer infrared as standard with their IP cameras and they include Dahua, Axis, Avigilon and Hikvision.
Low Light Night Vision Cameras
Low light CCTV cameras can magnify the limited light available in semi-dark conditions and use it to produce a colour image. At Intellisec our most popular low light CCTV cameras are the Hikvision Darkfighter series (below left) and the Bosch Starlight series (below right).
Thermal cameras are the only type of CCTV cameras that can operate in complete darkness. They are most commonly used for perimeter security in business part and residential estates, usually equipped with analytical features e.g. line detection. They are also used in remote, isolated areas such as on mining sites and farms. There are several leading thermal camera manufacturers and they include Axis (below left) and Dahua (below right).
Hand Held Thermal Cameras / Imagers
Hand held thermal cameras (also known as hand held thermal imagers) are used to detect problems in machinery and wiring before serious damage happens. The type of problems they are most commonly used to detect includes:
- Overheating wiring caused by too much current
- Old electrical components on the verge of failure
- Worn and misaligned components e.g. bearings, wheels and other moving parts
The portable nature of the hand held thermal cameras also means they can be used in remote and hard to reach locations.
Thermal Vision Monocular
For low cost night vision solution, we recommend a Thermal Vision Monocular. Simply hold it up to your eye and you can see objects in low light. Recommended for home security or for patrolling night security guards.
