Closed Circuit Television (CCTV) systems provide a multitude of visual technologies depending on specific security needs. Here you can learn more about the various types of camera systems that may be applicable to your unique security solution.
The most common and traditional camera type, Analog cameras, record to tape. New technologies utilize digital cameras which record to digital video recorders (DVR), this format offers extended flexibility for archival of video and remote monitoring needs.
Fixed camera systems remain in one position and provide focus on a specific area of surveillance. PTZ cameras allow for movement from left to right, up and down and also zoom and can be controlled fom a computer, DVR or PTZ joystick. These cameras are often seen in casinos, shopping malls and other public places where it is necessary to gain clear identification of moving people and objects.
Built tough to stand up to the elements, outdoor cameras provide the extra durability needed that often is not required with indoor setups.
At the cutting edge of surveillance camera security systems, IP cameras combine the security of a surveillance camera system with the benefit and convenience of IP-based cloud storage and access technology. Instead of being connected to a closed-circuit system, which restricts data internally within a direct wired system, IP cameras send and receive information via an internet connection. The information transmitted by an IP camera can then be housed in an internet-based central server, which is accessible from anywhere. This provides a major advantage to building and business owners who need to be able to monitor an area remotely.
Appropriate for any area in need of video surveillance, IP cameras can be used in both residential and business properties. The higher resolution provided by IP cameras are greater than what is available for more common closed-circuit camera system, bringing the advantage of getting a closer look at suspicious activity that may be occurring at a location.
Many cameras today are digital color with infrared LEDs which film in color by day and in black and white infrared (IR) by night. Infrared cameras provide the best picture in low-light situations.
It may be necessary to make the cameras protecting your location resistant to vandals. By deploying solutions with a tough exterior casing, you can gain the needed security in vulnerable locations.
Infrared cameras, as mentioned above, usually film in color during the day and switch to black and white when it becomes dark. The camera flips to black and white when photoelectric sensors detect darkness triggering the infrared LEDs to engage.
To achieve the best security solution, cameras in various shapes, sizes and materials can be used depending on the classifications required. As an example, dome cameras can be used in well-lit locations that have low ceilings requiring clearance, however bullet cameras may be more appropriate in low light conditions such as nightlife and entertainment operations. Corner cameras are optimal for tight spaces such as elevators and storage rooms. Larger cameras like standard box cameras serve as a visual deterrent as they are highly visible, whereas pinhole cameras are small to avoid detection.
