How to professionally control the special-purpose cameras has become a topic that most security personnel want to know.

Camera
The first point: lens selection and image monitoring range, try to use high-quality, high-light lens, such as Fujin, Tuli, and other well-known manufacturers to ensure the best image quality, when testing, as far as possible The camera is aimed at a single lane for monitoring, so that the license plate is more detailed and obvious.
The second point: the adjustment of the line lock of the special camera for traffic. When the line lock is not locked, the image of the camera will appear flicker and dark after setting the shutter. At this time, the line lock of the special camera for traffic needs to be readjusted, that is, V- PHASE, can be fine-tuned with a flat-blade screwdriver. The method of locking the line lock can be tested by fluorescent lamp. Set the shutter value of the camera to 1/100000S. If the brightness of the image is normal, the line lock is locked. Otherwise, it needs to be re-set. adjust.
The third point: AGC gain value setting, AGC0DB-30DB adjustable, this setting can adjust the camera's noise at night, the smaller the AGC value, the smaller the noise, the smaller the value, the overall brightness of the image will decrease.
The fourth point: the adjustment of the lens voltage of the special camera for traffic (IRIS), because the lenses used are different, after re-changing the lens, the IRS potential needs to be readjusted. When adjusting this parameter, it is better to have a sunlight during the day. Under the debugging, the normal light does not whitish in the strong light environment during debugging, and the aperture can be opened after the lens is held by the hand, and the effect is best.
The fifth point: camera shutter setting (AEShutter), SN-BXC0468CRS and SN-BXC0582CRS provide a variety of shutter modes, adjust the speed according to the speed of the adjustment, in the city road monitoring because the speed is not very fast (about 30 km / hour ), the shutter can be set to 1/250s, so that you can achieve good brightness at night and clearly see the license plate. In highway monitoring, the speed is generally above 100KM/H, so the shutter should be set to 1/1000s. The specific settings can be determined according to the actual situation. The higher the shutter value, the lower the brightness of the image.
Sixth point: Day & night mode selection, in order to clearly distinguish the color information of the vehicle at night, the day and night mode can be adjusted to Day, thereby forcing the traffic camera to not turn black and white.
The seventh point: sharpness, the newly developed SN-BXC0468CRS improves sharpness, so the license plate can be more easily identified. During commissioning, the sharpness of the traffic camera can be adjusted according to the customer's preference. The camera has OFF, Low, Mid, High, and select items. For places with high sharpness requirements, the sharpness can be set to High.
Through the understanding of the seven characteristics, I hope that everyone has a certain grasp of the regulation of traffic-specific cameras, and it is helpful to everyone.
