Types of CCTV Camera

 

Types of CCTV Camera

New technology is continuously being developed to launch cameras with enhanced features to improve the quality of imagery, range distance and the areas that can be scanned in order to will help to detect and identify.

Each manufacturer will have its own model range, but in essence the type of CCTV camera will fall under on the the following categories:

High-Definition (HD) CCTV Camera

High definition cameras have such a high resolution that they’re mainly used in high risk environments where highly valuable stock or confidential data is stored. They enable excellent quality images to be recorded of people entering and exiting, as well as the ability to zoom in for extra clarity.

Network/IP CCTV Camera

Whether hardwired or wireless, these cameras transmit images over the internet, often compressing the bandwidth so as not to overwhelm the web. Footage is often stored on network video recorders (NVRs) or accessed via secure software. IP cameras don’t require a separate cable to send images over longer distances so are easier to install.

Wireless CCTV Camera

Wireless cameras are exactly that – wireless. They allow greater flexibility in location and are much quicker and easier to install. They’re suited to most environments, but locations such as stately homes, museums, churches etc where the presence of wires would be unsightly.

Dome CCTV Camera

Dome CCTV cameras are one of the most common types of camera. Suitable for use both indoor and outdoor applications.  Named because of the dome-shaped housing within which the camera is mounted, these cameras are ideal for deterring crime as it is not easy for intruders to see which way the camera is facing and try to evade detection.

Speed dome cameras are also available. These cameras allow an operator to pan/tilt/zoom and spin quickly, giving them a greater ability to focus on specific events.

Bullet CCTV Camera

Bullet CCTV cameras are called so because of their long, cylindrical shape. These are often used where long-distance viewing is required, or in fixed locations, as they don’t typically come with a pan/tilt/zoom option. They can be wall or ceiling mounted and are suitable for both indoor and outdoor use. Protective casings are also available to make the camera waterproof and to protect the camera lens from dust and dirt in environments where these conditions a re likely to inhibit clear vision.

C-Mount CCTV Camera

C-mount CCTV cameras have detachable lenses which means they can be configured to fit different applications. Standard CCTV camera lenses can typically only cover distances of between 35 and 40ft. However, a C-mount CCTV camera can cover distances greater than 40ft by installing special lenses.

PTZ Pan Tilt & Zoom Camera

PTZ cameras allow the camera to be moved left or right (panning), up and down (tilting) and zoomed closer or farther. These cameras are used in situations where there an operating sitting in a control room who is manually operating and monitoring on-site security systems from a remote location.

Day/Night CCTV Camera

Day/night CCTV cameras are able to capture clear video images in varying light conditions and in the dark.

The day/night camera is most suited to outdoor applications, and can function with glare, direct sunlight, reflections and strong backlight.

Infrared/Night Vision CCTV Camera

Night-vision CCTV cameras can see images in pitch black conditions using infrared LEDs. They’re best suited to outdoor environments where the lighting is poor to zero.

Thermal CCTV Camera

Thermal cameras deliver images of objects emitting heat that the naked eye or conventional HD camera’s might not see such as intruders trying to hide behind foliage or obstructions. Faulty machinery, corroded electrics, and damaged components will often display abnormal temperatures prior to complete failure. The use of thermal cameras can help to detect these early signs and reduce fire risk. Thermal cameras can also detect human body temperature and their help identify people with a fever and help avoid the spread of infectious diseases.
