CCTV (closed-circuit television), also known as video surveillance. The video cameras are used to transmit video signal to a specific place on a limited set of monitors.

CCTV Camera Systems
Wired Systems: Commonly found in large premises such as warehouses, shopping centres and stadiums. The wired system runs off a mains power supply, this CCTV system will connect a camera directly to a recorder, the recorder is then connected to a router which transmits the video signal to its required destination. Furthermore, the signals can be transmitted internally and externally.
Wireless Systems: A Wireless system is often used in homes or small businesses. As the name suggests all connections are wireless. The cameras transmit video signals over radio bands to a receiver with an inbuilt hard drive, additionally, sine receivers will upload directly to the cloud. Monitors connected to the receiver can display live feeds.
IP Cameras: IP stands for Internet protocol. IP cameras are designed similar to a standard webcam. The camera receives and transmits video data over a network or the internet, in some cases it’ll use both. The difference between a webcam & IP camera is an IP camera operates as a standalone device with a unique IP address. Lastly, its important to realise that both these cameras can be used on a wired system or a wireless system.
Choosing a CCTV Camera
When choosing a CCTV camera, consider where it will be installed (indoor or outdoor), the camera type (bullet, dome, turret or PTZ), and the resolution needed for clear images, especially for identifying people or vehicles. Ensure it has suitable night vision, an appropriate field of view for the area you want to cover, and reliable motion detection with alerts. Decide between wired cameras for stability or wireless for easier installation, choose how footage will be stored (cloud, local, or both), and look for useful smart features such as mobile app access or AI detection, while balancing all of this with your budget and security needs.

- How clear must the footage be?
