The basic principle of working with the license plate camera is to convert the optical image signal into an electrical signal. When we shoot an object, the light reflected by this object is collected by the camera lens, so that it is focused on the light-receiving surface of the camera device, and then the light is converted into electrical energy through the camera device, which results in a video signal, but the signal is weak. It needs to be amplified by a preamplifier circuit, and processed and adjusted through various circuits. Finally, the standard signal can be sent to recording media such as video recording, or it can be transmitted through the transmission system or displayed on the monitor.
installation steps
The first step: Take out the bracket and prepare tools and parts: Plug, screw, screwdriver, hammer, electric drill, and other necessary tools. Check the size of the plug and tapping screws according to the pre-determined mounting position. Check whether the screw of the bracket and the screw of the camera base are appropriate, whether the pre-embedded pipeline interface is properly handled, and whether the test cable is unblocked, and then enter the installation procedure [1].
The second step: take out the camera, according to the pre-determined camera lens model and specifications, carefully install the lens (infrared integrated camera does not need to install the lens), be careful not to touch the lens and CCD confirmed firmly fixed, turn on the power, Connect the host or field monitor, small TV, etc. to adjust the aperture.
Step 3: Take out the brackets, plugs, screws, screwdrivers, hammers, electric drills and other tools. Install the brackets according to the pre-determined position. After a firm inspection, mount the camera in the agreed direction;
Step 4: If you need to install the guard, after the second step, install the guard directly from here.
1. Open the shield cover and tailgate;
2. Pull out the fixed metal plate and fix the camera;
3, the power adapter into the shield;
4. Reset the upper cover plate and the rear baffle, straighten the cable, fix it, and install it on the bracket.
Step 5: Insert the BNC plug of the soldered video cable into the socket of the video cable and confirm that it is firmly fixed.
Step 6: Plug the power adapter's power output plug into the monitoring camera's power jack and confirm the firmness.
Step 7: Connect the other end of the cable to the control panel or monitor (television) to ensure it is secure.
Step 8: Switch on the power of the monitoring host and camera, and adjust the camera angle to the predetermined range through the monitor.
common problem
1, the license plate area text vertical shading block?
The camera itself has a strong light suppression function, this phenomenon is less, the installation process also need to avoid strong light direct to the camera to reduce this possibility 2, the license plate text is not easy to identify the license plate text is too small, need to adjust the focal length of the lens to facilitate the back-end equipment Recognition, but not too large, to facilitate the time when the license plate appears in the video as much as possible 3, the license plate recognition results are inconsistent. Some light blue bottom white license plate than the dark blue white recognition effect is poor, especially easy to reflect, into a white 朦For the actual use of the image, the light blue license plate should be used to adjust the brightness to the brightness adjustment standard, and the brightness should be slightly darker.
4, the body recognition is not good to optimize the menu according to the license plate, if the body needs to be clear, need to be as 6.4 instructions, the gain control hit the middle, then the noise may be greater, the license plate effect may not be very good.
