Surveillance camera installation process

1. Test before installation

1. Use the SYV75-3 video cable to make a test cable about 3 meters long with BNC headers at both ends.

2. Prepare a monitor or hard disk video recorder. The hard disk video recorder can be embedded or PC type with complete software configuration.

3. Before powering on, figure out the power supply voltage of the camera, and test the power supply voltage with a multimeter. The voltage deviation of the test is ±10% of the standard voltage. Power supplies that exceed this standard are prohibited from being used.

4. Fit the lens for the fixed camera, pay attention to whether the interface between the lens and the camera is a C-type or CS-type interface (this should be remembered, otherwise the C-type lens is directly screwed into the CS interface camera, which may damage the camera. CCD chip), if it is an integrated fixed camera, this step can be omitted.

5. When installing the lens, first remove the camera and the protective cover of the lens, and then gently screw the lens into the lens interface of the camera and make it in place. For automatic iris lenses, the control line of the lens should also be connected to the automatic iris interface of the camera.

6. Respectively test AGC ON/OFF (automatic gain control), ATW ON/OFF (automatic white balance), ALC/ELC (automatic brightness control/electronic brightness control), BLC ON/OFF (backlight compensation switch), LL/INT (Synchronization selection switch), VIDEO/DC (lens control signal selection switch), SOFT/SHARP (detail level selection switch), FLICKERLE (no flicker mode) and other functions, and make a test record, whether it meets the actual needs of the scene .

7. For PTZ and dome, encode the address, baud rate, and protocol of the decoder board according to the manual, and mark it with label paper. The address code is coded in sequence according to the camera number. If the protocol has no special requirements, PELCO is generally used. The baud rate is 2400KPS, and the corresponding setting is made on the hard disk video recorder or matrix.

8. Follow the instructions to enter the fast dome or pan/tilt menu. For outdoor models, set the camera function to day and night conversion.

9. Perform a zoom test on the pan/tilt or dome left and right, and the camera lens, in the farthest and nearest state, and record the test results. Only those who meet the requirements can be installed, and those that do not meet the requirements will be returned to the manufacturer. Perform repairs.

10. Set a number of preset positions for the dome, and then test whether the dome meets the design requirements by adjusting the preset points.
