CLOSE CIRCUIT TV (CCTV)
Closed-circuit television (CCTV) is a popular form of surveillance that uses video cameras to transmit a signal to a specific destination on a limited set of monitors in a closed network. Banks, airports, industrial plants, military installations, and convenience stores commonly use CCTV, which can operate continuously or can be activated to monitor particular events. CCTV is a popular tool not only for security, but also for monitoring the operations of a business or organisation.
When choosing CCTV for security or business needs, the key questions are what kind of camera to use, where to store the images and how to monitor and access them. A consultation with Ecam can determine the answers to these questions, which depend on many factors including purpose, location and local conditions.
CCTV systems use many different camera types depending on the security needs. Common camera classifications among which customers can choose include:
ANALOG OR DIGITAL IP
Analog cameras, a traditional type, record to a digital video recorder (DVR). Digital IP cameras record to network video recorders (NVR), both formats offers more flexible storage options.
FIXED OR PTZ CAMERAS
Fixed cameras remain in one position. PTZ cameras can be moved left to right, up and down and zoomed in and out via a computer, DVR, NVR or PTZ joystick. These cameras often are used in casinos, shopping malls and other public places where it is imperative to access clear identification of moving people and objects.
INDOOR OR OUTDOOR
Outdoor cameras are built tough to withstand the elements, while indoor cameras can be more delicate. Infrared Security Cameras. Most cameras today are digital color with infrred LEDs, which films in color by day and in black and white IR by night. Infrared cameras provide the best picture in low-light viewing situations.
Depending on the location of the camera, it may be necessary to make it resistant to vandals with a tough exterior. Consider this option for cameras in a vulnerable location.
DAY & NIGHT CAMERA
Infrared cameras usually film in colour during the day and then switch to black and white when it becomes dark. A photoelectric sensor detects the darkness and turns on the LEDs and flips the camera to black and white.
DOME, BULLET, BOX & PINHOLE CAMERAS
Camera shapes, sizes and materials vary according to which of the above classifications are selected. For example, dome cameras are used in well-lit locations with low ceilings, whereas bullet cameras are used in low light conditions such as nightlife operations. Corner cameras are used in tight spaces such as elevators. Some larger cameras like standard box cameras may serve as a visual deterrent, while others, like pinhole cameras, are small in order to avoid detection.
