Tin Sheng Micro; as a remote wireless monitoring how to do?

Many customers and me talk about what wireless video surveillance is based on what signals are transmitted and how far it can be transmitted. The distance can be seen on the phone. Waiting for a series of questions.

In fact, the so-called wireless transmission in the true sense of the word does not require the transmission of signals through cables. Generally, wireless video signals are used to transmit video images of surveillance cameras. In simple terms, two devices are used to transmit and receive signals. Wireless video transmission equipment usually consists of: transmitter receiver, transmit and receive antennas, power supply and video cable. Since the wireless transceiver is a microwave signal transmission, it has a distinction between frequency bands. The common frequency band we use is 2.4G\5.8G\1.2G\. The transmission distance can be from 200 meters to 50KM, but in any case, wireless Both transmitting and receiving devices should be in a unified frequency band so that they can communicate with each other. During installation, the wireless video transceiver is powered on first. The camera at the front end and the transmitter are connected through a short cable, and then the position of the transmitting signal antenna is fixed, and the transmission direction of the wireless receiver is directly transmitted. The transmission direction of the transceiver is generally For straight-line transmission, depending on the environment there is also a sector-angle signal spread, or a 360-degree omnidirectional transmission signal.

There are two general types of wireless video transmissions:

Analog wireless transmission equipment and digital wireless video transmission equipment, distinguish by characteristics: analog wireless transmission equipment put into the market early, can only transmit analog images, transmission of video images can only be achieved when a set of transmission equipment with a camera, and in the same reception The equipment in the same area will not exceed 4 sets at most, unless you expand the equipment of other frequency bands, you can increase the number of transmissions of surveillance cameras.

Digital wireless video transmission equipment can transmit millions of high-definition network cameras and support digital encryption. In the same receiving equipment, the same frequency band can receive more than 30 devices. In the first stage, if there are multiple network cameras, they can be integrated through switches and transmitted through a set of wireless digital video transmission devices. This means that a set of wireless digital transmission devices can carry multi-channel network HD cameras. Multiple wireless digital transmitters can be used in a distributed environment where the front camera is located in a decentralized environment. One point-to-multipoint receiver is used in the monitoring room. A one-to-many wireless video reception method can not only ensure the high-definition and fluency of the picture, but also improve work efficiency and reduce the cost of the customer's investment in the economy. One-to-many transmission can be used with different antennas depending on the environment and distance. Digital wireless video transmission equipment mainly RJ45 network port connection transmission, wireless transmission video transmission equipment, also known as "wireless bridge" can transmit video signals, network signals, data instrument signals, alarm signals, all network interface equipment transmission.

Transmission characteristics are generally: point-to-point transmission, point multi-point transmission, relay wireless transmission, multi-camera transmission, the farthest point to point transmission can be 50 kilometers away, relay transmission distance is not limited, such as wireless monitoring of highways and tunnels for relay wireless Video transmission. The wireless bridge can be covered by the crop wireless WIFI network, and the mobile phone or the computer terminal can receive the wireless signal and use it on the Internet. The coverage area is wide and the transmission distance is long. Wireless digital expansion has strong performance. In the pre-installed wireless monitoring project, when you need to add a camera and build a camera, you only need to add the device, and the wireless will be completely transformed, making the installation operation easy and saving a lot of time.

With the changes of the times, the development of science and technology humanities more and more users accept and intimate, Nanchang City, Tin Shing Microvision Technology Co., Ltd., specializing in wireless monitoring. Wireless video surveillance is safe, stable, and has strong expansion performance. It is easy to install and save time. According to the design of the wireless monitoring project, we don't need to worry about the phenomenon that the equipment can't be used or can't be stable. We only provide reliable wireless video transmission equipment.
