What is the internal and external synchronization of the camera?
When the transmitter and receiver are synchronized, the signal synchronization must be completed. The horizontal synchronization signal controls the horizontal scanning and the vertical synchronization signal controls the vertical scanning. Synchronization system is divided into the following categories: 1, internal synchronization is completed by the synchronization signal of the camera internal synchronization signal generation circuit. 2. The external synchronization signal is distributed to the external synchronization input of the camera by the external synchronization signal generator to complete synchronization. 3. Power source (line lock) synchronization The vertical drive (VD) synchronization is completed by using the AC power cycle of the camera. Answer: Internal synchronization is completed by the synchronization signal of the camera's internal synchronization signal generation circuit. Answer: Use external synchronization signal, power supply or synchronization signal generator to send synchronization signal to the external synchronization input of the camera. Input VD synchronization pulse on the camera signal cable to complete external VD synchronization. Multi-camera external synchronization is a fixed external synchronization for multiple cameras, so that each camera can work under the same conditions. Because the cameras are synchronized, even if one of the cameras switches to other scenes, the picture of the synchronized camera will not be distorted. return
