1. Analog Video Camera + Analog Wireless Video Surveillance Equipment + Hard Disk Video Recorder (DVR): This method was used more than a few years ago because it is more convenient to set up, the networking is also very simple, and the cost is relatively low. This method can only be used for one-to-one transmission and is suitable for situations where there are few points. At present, this kind of transmission method has been gradually eliminated. Due to the appearance of high-definition cameras, people's requirements for image quality and clarity are getting higher and higher. Analog wireless monitoring equipment cannot transmit high-definition signals and is subject to frequency constraints. Because of this wireless monitoring equipment is not used much now on large projects.
2. Analog Video Camera + Encoder + Wireless Bridge + Decoder + Hard Disk Video Recorder (DVR): This type of transmission is generally used at the front end to generate signals from analog cameras. The analog signal needs to transmit video signals through a wireless bridge. When it is necessary to convert the analog signal into a digital signal and then transmit it through a wireless bridge, the digital signal cannot directly enter the DVR. The signal must be restored by the decoder before entering the DVR to store the video. This kind of transmission method is very complicated to use, and the cost is relatively high, so at present this kind of transmission method is generally only used in some project transformation.
3. Network Camera + Wireless Bridge + Network Video Recorder (NVR): This transmission method has just emerged in the past two years. The network camera has completely freed itself from the constraints of analog monitoring, and has good scalability, strong centralized management capabilities, and construction costs. Low-level advantages. The signal coming out of the network camera is a digital signal. It is not necessary to convert the signal. It can be directly connected with the switch or wireless bridge. The network hard disk recorder can be directly connected with a bridge or a switch. This transmission method makes the wireless monitoring system more convenient. easy and convenient. If you want to transmit high-definition signals, you can directly match the high-definition network camera, this transmission method is not only save money and simple and convenient. At present, most of the new monitoring projects are implemented using this transmission method. Shenzhen Leian Technology also recommends that you choose this transmission method to achieve wireless video surveillance.
