Surveillance cameras are common on the market, and their prices are much cheaper than dedicated cameras for video conferencing. So, can surveillance cameras be used in web conferencing systems? Before answering this question, we must first understand the technical principles of cameras. Both surveillance cameras and dedicated video conferencing cameras collect data through the camera lens, and this data is an analog signal. The difference between surveillance cameras and video conferencing cameras mainly has two aspects. One is the camera lens, and the other is the camera output interface. Surveillance camera lenses usually have lower resolution than video conferencing cameras. This is because video conferencing cameras require high-quality images, and surveillance cameras generally cost a few hundred dollars, while video conferencing cameras usually cost more than 2,000 yuan. This price difference is mainly due to the difference in the lens. The other difference is the interface. Video conferencing cameras usually have two types of interfaces, one is a USB interface and the other is an AV interface. The USB interface outputs a digital signal, and the AV interface outputs an analog signal. If you want to use a video conferencing camera that uses an AV interface in a web conferencing system, you will need to purchase a capture card. The role of the capture card is to convert the analog signal from the AV interface into a digital signal. On the other hand, USB video conferencing cameras can be used directly in web conferencing systems without using capture cards. Surveillance cameras also have two interfaces, one is a BNC interface and the other is a LAN terminal. The BNC interface outputs an analog signal and can be directly connected to the video data captured by a surveillance capture card. On the other hand, the LAN terminal is usually used for surveillance cameras with custom protocols and is usually not suitable for video conferencing systems.

After understanding the technical principles and differences between surveillance cameras and video conferencing cameras, we will explain whether surveillance cameras can be used in web conferencing systems. If the interface of a surveillance camera is BNC, it can certainly be used in video conferencing. Because the data captured from the BNC interface and the data captured from the AV interface of a video conferencing camera are the same, and if you use a BNC to AV conversion adapter, you can convert the BNC interface to an AV interface and connect it to a video capture card. On the other hand, if the interface of a surveillance camera is a LAN cable, it usually uses its own protocol and is not suitable for a video conferencing system. Similarly, video conferencing cameras can usually be used for monitoring if they have an AV interface, but video conferencing cameras with USB interfaces are usually not suitable for surveillance systems. WEILAILIFEI's home wireless solar-powered, battery-powered and home POE-powered security cameras can be monitored remotely with multiple devices. After connecting the recorder and router with a LAN cable and installing the app, you can monitor, watch, and talk with your family on various devices such as tablets, smartphones, and computers outside.

They can also be installed outdoors. 5 million high-definition cameras, improved heat dissipation and durability, and four times longer service life.

In short, the BNC interface of the surveillance camera and the AV interface of the video conferencing camera are compatible, and the two different types of cameras can basically be replaced. However, considering the use of a web conferencing system, it is recommended to use a dedicated video conferencing camera with the video conferencing system to improve the quality of the video conference.
