Coaxial video cable, twisted pair, power line PLC, network cable, 4 kinds of transmission methods, any networking, easy construction, H.264 compression format, solar eclipse + light suppression function + electronic shutter adjustable type: 1/3SONYICX639CCD, color, 0.01 When the LUXatF1.2540 line/special light source is turned on, the 0.001LUXatF1.2600 line uses a special auxiliary light source (147 LEDs). This special light source has a higher recognition rate for the old license plate (no license plate with the character and background color returning), and makes up for it. Traditional white light for the low recognition rate of the old license plate; Filling distance: 1-60 meters adjustable, clear color images can be obtained at night; built-in lens: f = 6-60mm auto iris adjustable focus lens, according to need Freely adjust the light suppression function automatic conversion. Built-in temperature control device, so that the body temperature is controlled at about 45 degrees, thereby extending the life of the IP66 waterproof standard, waterproof and anti-fog; the front of the unique double glass design, can effectively prevent the auxiliary light to open Halo and flare phenomenon.
The system is optimized for low-cost, close-range license plates and car bodies, which are used at bay and parking lots.

3. The working principle of the basic principles <br> <br> license plate camera work, i.e., the optical image signals into electrical signals. 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.
2: Installation steps <br> <br> first step: Take out the bracket, ready for tools and parts: plug up the necessary tools, screws, screwdriver, hammer, drill and so on; according to pre-determined installation location, good check up Plug and self-tapping screws, size and type, try the bracket screw and camera base screw is appropriate, whether the embedded pipeline interface is handled well, test the cable is free, ready to enter the installation program [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.
