Small hidden CCTV camera
A wireless CCTV camera is a type of CCTV camera that operates on the basis of data transmission over a network. Surveillance systems that use this type of CCTV camera consist of wireless transmitter and receiver devices. Wireless CCTV systems are capable of transmitting a signal of about 5.8 GHz over a distance of 4 miles. Wireless CCTV cameras are used in cases where the cabling of the camera installation location is very limited or budget management is important for the individual. Ram-based small CCTV systems are the most popular systems. These cameras are specially designed for outdoor installation. The image recording quality of wireless cameras has been reported to be excellent.

In general, all types of wireless CCTV cameras can be installed in all environmental and weather conditions. To better understand the performance of wireless cameras, we will give you an example of the price of a small hidden camera. The figure below shows a small audio listening device installing a wireless CCTV camera in two separate buildings. The two buildings are spaced apart and separately support a wireless network.
Depending on the figure, Building A consists of two analog CCTV cameras connected directly to the video recorder (DVR or NVR) via the RG59 coaxial cable. The video recorder is connected to the building network via a Cat-5 cable. To the right of this equipment is a modem that provides the camera with an Inteet connection if needed and the necessary equipment is prepared. The wireless receiver is mounted on the left side of the modem, outside the building and on the outside wall.
Endoscopic hose camera
The wireless receiver communicates directly with the wireless transmitter mounted on the opposite wall in Building B. The wireless transmitter in building B is connected to the network switch throughout the building via a Cat-5 cable; Network switches are also connected to the two main network servers. The main servers are connected to the wireless CCTV camera with an RG59 coaxial cable. The purpose of connecting the system to the network server is to convert analog signals to digital signals and transmit it to the network via TCP / IP as well as the camera transmitter.
In the example above, both systems monitor the environment separately; In building A, cameras are installed that cannot be connected to the network, but in building B, a wireless CCTV camera is installed that is connected to the network. If a CCTV system has all the necessary equipment to connect to the network, the cameras of the two buildings will be able to share their information.
