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 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.
