What is the name of the camera with the monitor?
Called the probe, you have to look at the name of the device, do this thing too many manufacturers, the shape is the same, this is considered behind
What do I need to do with video surveillance systems?
Video surveillance system consists of real-time control system, monitoring system and management information system. Real-time control system to complete the real-time data acquisition and processing, storage, feedback function; monitoring system to complete the monitoring of all-weather monitoring, multi-operation control point to switch multiple images; management information system to complete the required information collection , Receive, transfer, processing, processing, is the control of the entire system core.
What is the monitor for the video recorder?
There are four split, nine split, sixteen split, you can display 4,9,16 camera images on one monitor at the same time, or you can send it to the recorder.
There are cameras at the fork in the expressway
The first speed camera is a shape like a rectangular box, play a decisive role is actually connected with the radar module. Radar detection vehicle over speed will be linked when the camera to take pictures of evidence. The speed radar uses the Doppler effect principle. When the vehicle approaches the radar antenna, the reflected signal frequency will be higher than the transmitter frequency. When the vehicle is away from the antenna, the reflected signal frequency will be lower than the transmitter rate. This can be calculated by the frequency of the value of the target and the relative speed of the radar.
What is the 960h in the surveillance camera?
Samsung currently developed the SV5 chip with the same performance with Effio, simply said front-end use 960H CCD and Samsung SV5 chip with the use of TW9960 chip (for storage DVR) 960H
Monitor the camera if the power supply to him a large current, pay attention to the current is not the voltage, the voltage is 12V, then what will happen to the camera?
The voltage is constant, the current is not increased, such as the camera comes standard with the adapter power supply is 12V / 1A, if the switch for 12V / 5A or 10A, 20A power supply is the same, will not have any impact on the camera. The actual operating current of the camera does not increase as the power of the power increases.
What are the problems with the surveillance camera?
Monitoring the failure of the camera performance for several aspects: ① power supply is not correct equipment failure. ② equipment line connection reasons. ③ the quality of the equipment or components themselves. If it is installed problems caused by the problem, you can solve, but if it is to monitor the camera's own reasons, it would return to the factory maintenance. Now many manufacturers have done a good job after-sales service, such as Hai Kang, Dahua, Zhong Ying Xin and so on.
Monitor the camera with high illumination and low light
Is the brightness of the shooting scene requirements. Low-light camera in a dark environment to shoot a more bright scene.
