Types of CCTV Cameras in UK
There are many types of CCTV cameras used in UK based companies. CCTV cameras can be categorized by the types of images they are able to capture, the type of connection to the monitor or video recording device, the amount of frames they can take per minute, whether they are able to move position, and special functions they can provide.
CCTV cameras available in UK generally take both black and white or colour video images. In addition, many CCTV cameras can even have night vision capabilities aside from colour or black and white images which allow to view and record low light images using special technology.
Frames per Second:
Frames per second means the amounts of full frames that a CCTV video camera captures and sends to a recording device or monitor per second for security purpose from an installation point at a UK based company. While most CCTV video camera systems in UK are easily able to capture 30 or more frames per second (30 fps is considered real time), the amount of video tape or digital storage required to store video or images would be enormous to record every moment of everyday. For most utility or general stores, video or still camera speeds of 1 to 6 frames per second are more than enough to catch and record a perpetrator committing a crime.
Pan Tilt Zoom (PTZ) Cameras:
These types of CCTV videos cameras allow UK companies controlling the surveillance of areas to move the camera remotely, usually with an RF or wired controller. Most moveable video cameras allow the person monitoring it to move the CCTV camera from right to left (pan) up and down (tilt) and from a tight angle to a wide angle (close up zoom).
Surveillance Cameras with Special Accessories:
Certain CCTV cameras have special functions which are made for specialty uses. For instance, there are extremely small surveillance video cameras in UK that are used for spying (Nanny Cams), there are CCTV cameras that are made for night viewing, cameras that are vandal resistant and cameras that are specifically made for indoor or outdoor uses.
Wired Vs. Wireless Connection
There are two main types of connections for CCTV video surveillance cameras to the monitor or recording device. Camera can either be a fixed cable or a wireless connection.
Fixed Cable Connection
Fixed cable connection means that your video surveillance camera will be physically connected to your monitor or recording device via cord transmitting information to your UK based company’s security office. Usually coaxial cables are used for surveillance video camera in UK. Most of the times, these cables are similar to your normal home TV cables. Lengths vary from 25, 35, 50, 100 or 500 feet for these CCTV cameras in UK. As the distance and length of these cables increase, you may see degradation in signal quality. For distances of 100 or 150 feet, you can purchase higher quality coaxial cables such as RG59 coaxial cable for distances up to 500 feet and for distances more than 500 feet, but less than 1,500 feet, you can purchase CAT5 cable.
Most wireless CCTV video surveillance cameras in UK use the 2.4 Gigahertz frequencies to transmit their video images to a monitor or DVR (digital video recorder). Usually, frequencies can be changed a bit to accommodate more than one group of cameras in a specific space. Wireless CCTV video cameras used at this frequency can easily transmit through most walls and obstacles; however each individual location will have its own operational limits. Expect most wireless CCTV surveillance cameras to send data to a range of about 150 feet, however many will more likely work well when transmitting less than 120 feet. A clear line of sight transmission is required for them to operate well and will always work the best.
