What is CCTV and How It Works

A CCTV (Closed-Circuit Television) system is a type of surveillance system that uses video cameras to transmit a signal to a specific location, usually a set of monitors or recording devices, where the footage can be viewed and monitored in real-time. CCTV cameras are often used for security and monitoring purposes in public places, businesses, and residential properties, and are designed to capture footage of events and activities that occur within their view.

If you want to remotely control the camera position, you should choose a Pan-Tilt-Zoom (PTZ) camera for your CCTV system.

PTZ cameras can be controlled remotely through a controller or software, allowing you to adjust the camera's position, angle, and zoom. With a PTZ camera, you can pan (move the camera left or right), tilt (move the camera up or down), and zoom in and out to capture specific details.

PTZ cameras are a popular choice for surveillance applications that require flexible monitoring and coverage, such as in large areas like parking lots, warehouses, and campuses. With PTZ cameras, you can monitor a wider area and capture more details, and you can also focus on specific areas or events as needed.

Keep in mind that PTZ cameras are generally more expensive than fixed cameras, so you should consider your budget and needs before deciding on a camera type. Additionally, you'll need to ensure that your CCTV system is compatible with PTZ cameras and that you have the necessary hardware and software to control and manage them remotely.
