Wireless bridge built-in antenna
The built-in antenna is small and easy to install due to the integration of the antenna and the device. However, the built-in antenna is generally used in a short-distance wireless transmission system. In a long-distance wireless video transmission system, an antenna is used as much as possible. Because the gain of the built-in antenna is generally small, the transmission distance must be closer. The wireless network bridge produced by Shenzhen Leian Technology currently has a built-in antenna transmission up to 20 kilometers away. If it is more than 20 kilometers, it needs an external antenna to realize the model LA-5825. 
Wireless bridge external antenna
It is recommended that an external high-gain antenna be used for wireless bridges more than 20 kilometers from Shenzhen Leian Technology. This is because the gain of the built-in antenna will not be too large. Therefore, external antennas are generally used in long-distance wireless monitoring systems.
In some cases, the video signal needs to be transmitted in a multiple-receiving manner, and the angle of the built-in antenna is relatively small. If it is necessary to increase the receiving angle, an external antenna is used to implement the video signal. Therefore, we can use the LA-5810-N wireless bridge produced by Shenzhen Leion Technology to connect any angle antenna to achieve high-angle reception. 
The use of wireless bridges is very flexible. We can choose different products according to different environments, different point locations, and different transmission distances to design various wireless monitoring solutions for you, for you in wireless monitoring projects.

Wireless Bridges with Internal or External Antennas in Wireless Video Surveillance System
Wireless video surveillance, wireless bridge is used to transmit video, data, audio and other signal transmission equipment, and the wireless bridge signal must be transmitted through the antenna, the antenna is an essential part of the use of wireless bridge . Then, in the use of wireless bridges, the antenna is generally divided into two types: built-in antenna and external antenna. Let's introduce how to use the built-in antenna and external antenna.
