Closed Circuit Television (CCTV) cameras are an essential tool for surveillance and security in both residential and commercial settings. They are used to monitor and record activity in and around a property, providing valuable evidence in case of theft, vandalism, or other crimes. In this article, we’ll go over some of the basics of CCTV cameras, including how they work, the types available, and their benefits.
How do CCTV Cameras work?
CCTV cameras work by capturing video footage of the area they are pointed at, which is then transmitted to a recording device, such as a Digital Video Recorder (DVR) or Network Video Recorder (NVR). This footage can be viewed live on a monitor or remotely via a computer, smartphone, or tablet.
CCTV cameras typically use either analog or digital technology. Analog cameras transmit video footage as an analog signal over coaxial cables, while digital cameras use IP (Internet Protocol) technology to transmit footage over a network. Digital cameras are more common these days as they offer higher resolution and better video quality.
Types of CCTV Cameras
There are several different types of CCTV cameras, each with its own unique features and capabilities. Some of the most common types include:
- Dome Cameras – These cameras are shaped like a dome and are commonly used indoors. They offer a wide viewing angle, making them ideal for monitoring large areas.
- Bullet Cameras – These cameras are long and cylindrical, and are often used outdoors. They have a more focused view and are ideal for monitoring specific areas.
- PTZ Cameras – PTZ stands for Pan-Tilt-Zoom, and these cameras can be remotely controlled to pan, tilt, and zoom in on specific areas. They are commonly used in large outdoor areas such as parking lots and stadiums.
- Thermal Cameras – Thermal cameras use infrared technology to detect heat signatures, making them ideal for use in low-light or nighttime conditions. They are often used in outdoor settings where lighting is poor or nonexistent.
