CCTV systems consist of cameras that capture and record video footage. These cameras can be fixed in a specific direction or can be equipped with pan, tilt, and zoom (PTZ) capabilities to cover a wider area.
The video recorder is the central device that captures and stores the video footage from the cameras. There are different types of video recorders, including Digital Video Recorders (DVRs) and Network Video Recorders (NVRs), which can store the footage locally or on a networked storage device.
Monitors are used to display live or recorded video footage from the CCTV cameras. They are typically located at a central monitoring station or at various points where real-time surveillance is required.
CCTV systems require cables and wiring to connect the cameras to the video recorder and power source. The type and length of cables depend on the distance between the cameras and the video recorder.
Cameras and video recorders require power to operate. Power supply units or PoE (Power over Ethernet) switches are used to provide power to the cameras and video recorders.
The recorded video footage is stored either on the device itself (DVR or NVR) or on external storage drives. This allows for archiving and reviewing the footage when needed.
Many CCTV systems offer remote access capabilities, allowing users to view live or recorded video footage from the cameras using a computer, smartphone, or tablet. This enables monitoring and management of the CCTV system from anywhere with an internet connection.
