What Is an IR Bullet Camera?

Vehicle license plate camera is a mobile shooting device that integrates high-speed cameras. Within a 10-meter road monitoring range, slow-moving vehicles can stably and clearly capture color license plates under various light conditions. Body and other moving objects. Mainly used for toll stations and entrances. The ATV Baozhao license plate camera can clearly record vehicle license plates with speeds exceeding 300 kilometers per hour, and even the track of bullet shooting.

Frequently Asked Questions about License Plate Camera

1. Is the text in the license plate area blocked by a vertical halo?

The camera's strong light suppression function is good, this phenomenon is rare, and the installation process should also try to avoid strong light directly to the camera to reduce this possibility

2, the license plate text is not easy to identify

The license plate text is too small. You need to adjust the lens focal length to make it easier for the back-end equipment to recognize.

3. License plate recognition effect is inconsistent

Some license plates with white letters on a light blue background have a poorer recognition effect than white letters on a dark blue background. They are particularly easy to reflect light and reflect a white hazy image. In actual use, the brightness of the light blue license plate should be used as the brightness adjustment standard. The brightness is slightly dim.

4.Body recognition is not good

The menu is optimized to follow the license plate. If the body needs to be clear, you need to set the gain control to medium as described in 6.4. At this time, there may be a lot of noise and the license plate effect may not be good.
