What is the working principle of wireless monitoring?

Wireless monitoring system will be used in many places in life, so what is the working principle of such monitoring system and how to operate it? It can clearly capture some pictures and ensure the safety of many workplaces. Wireless monitoring is widely used. Some public places, some units and business departments will use such wireless monitoring, because it provides some protection for people's real life, so it is necessary to install such monitoring.

Wireless monitoring refers to a monitoring system that uses radio waves to transmit video, sound, data and other signals without wires (cables). Wireless monitoring system is a combination of monitoring and wireless transmission technology. It can transmit the field information from different places to the wireless monitoring center in real time by wireless communication means, and automatically form a video database for future retrieval. Let's first look at the working principle of wireless monitoring equipment.

principle of operation

Acquisition front end

The acquisition front-end is installed in the monitoring place by the user, including intelligent network camera and wireless alarm trigger, which is used to collect alarm information and monitoring pictures.

monitor terminal

Monitoring terminal refers to the equipment used by users to receive alarm information, view monitoring pictures and control the front end of acquisition, including computers and computers. Mobile phone, PDA, etc.

Service room

The service room is a special server room set up by Yuanjian Communication Company to ensure the normal operation of the system, including addressing server, SMS server and network hard disk server. The service room is maintained by farsighted communication company.

Equipment testing steps

First, connect the wireless surveillance camera to the power supply and the monitor (TV), and make sure that the wireless surveillance camera and the monitor (TV) can work normally.

Connect the transmitter, camera and power supply, connect the receiver, display and power supply, and then adjust the button on the receiver to select the channel, so that the channel on the receiver is completely consistent with the channel on the transmitter; So that the equipment can be used normally.

Matters needing attention

The receiver channel setting should correspond to the transmitter one by one.

The working principle of wireless monitoring is introduced in detail above. By understanding the role of wireless monitoring, we have a clear understanding. Wireless monitoring has a wide range of uses. The installation of wireless monitoring needs to understand certain working principles and operate according to certain installation methods. Many units and individuals install it because it can capture many pictures with practical significance. Once there are some criminal acts, you can call up the screen through wireless monitoring to help solve the case, which is of great significance in practical work.
