Serial camera as Security monitoring In recent years, serial cameras have been rapidly developed. At present, they are used in GPS vehicle platform management system, vehicle interior monitoring, security, remote monitoring, visual doorbell and other fields. The most popular applications are GPS vehicle mounted and remote monitoring. The selection of serial cameras is mainly in the following aspects:;
1: GPS protocol matching
The camera protocol can be matched according to the GPS terminal host. Our communication protocol is flexible and convenient. At present, it supports more than 30 GPS host protocols and its own active and passive protocols. It supports all current mainstream GPS and Beidou terminal communication protocols, and can make customized changes to the protocol and functions according to the specific requirements of customers for secondary development;
2: Serial camera interface
Serial cameras generally have three interfaces: RS-232, RS-485 and TTL. At present, there are many RS-232 and RS-485 interfaces for serial cameras in the market, RS-232 interface and simple image transmission protocol enable the camera to connect to the computer with various embedded systems. For example, the data transmission rate specified in the RS232 standard is 4800, 9600, 38400, 57600, and 115200 bauds per second, while the baud rates used by serial cameras are 9600 and 115200 bauds.
3: Serial camera pixel
There are 300000, 1.3 million and 2 million pixels of serial cameras. At present, more than one serial camera is GPS terminal monitoring, which is close monitoring, such as bus, car rental and bus monitoring. The 300000 pixel camera is basically OK, which can clearly capture the situation inside and outside the car, and compress and transmit the captured pictures to the GPS platform, The photos can be clearly seen on the GPS platform;
4: Serial camera output
The camera output is mainly digital information output and digital analog signal dual output. The digital output is mainly used for GPS vehicle monitoring, bus, taxi and bus remote monitoring, and the digital analog serial port dual output is currently used in more driving school training and examination projects;
