Wired vs wireless types of CCTV cameras
Some of our customers are confused about the difference between these two types of CCTV cameras.
Wired types of CCTV cameras
Wired security systems, also known as DVR (digital video recorder) security systems, are the most traditional type of CCTV, consisting of cameras and a recording device that is connected to a power source and the internet through a cable. The cameras can be powered either with separate wires for electricity and internet, or with a Power over Ethernet (PoE) cable, which requires only one cable to provide both power and internet.
They give more consistent streaming quality and support large installations. You get little or no network interference and they’re more secure.
The biggest downside is that they stop working when there’s a power cut, and the installation is fairly invasive which means they may not be feasible in historic buildings. They’re the right choice for warehouses, large working premises or any business with valuable equipment on site that needs to be protected reliably.
Wireless types of CCTV cameras
The primary distinction between a wired and wireless security camera system is that the recorded footage in wireless systems is delivered wirelessly from the camera to the recorder, whereas wired systems operate fully through cables. However, both require connected electricity.
Wireless security cameras are powered by a wire and connected to the internet via Wi-Fi, where the video is uploaded to a local storage device or the cloud.
The benefits are that they’re neater to install than wired cameras, they can be moved to different locations easily and they’re quite flexible. They can be a good solution for a small office or other business that wants an improved level of surveillance on a budget, but where reliability isn’t critical.
The downside is that they stop working properly if the Wi-Fi signal is weak and the signal is vulnerable to interference, they’re often quite easy to hack and they’re not ideal for large installations.
