Issue- This case regarding our Fix camera, Model- 6125 WDL & 6125 WDL- FA, observing that in night time live video camera was not able to capture the number plate, getting while wash totally. Even when IR getting on in that scenarion also unable to read the number plate while IR reflecting on number plate but can't read anything.
Analysis of this case-
In ther real time live system observe that the camera are install on approx 6 meter height from the ground level and FOP of camera is approx 3 meter. FOP of camera starting after 5metere from Camera Pillers. The target of camera is to capture the number plates of each vehicles which will crossing the FOP area of camera. Through out the ANPR system cam read the no and anlysis the requirement in database and can procedd further.
In such scenarion, observe that in the day time camera is able to cpature all the number plates but unable to get capture in night time, once the IR get on and it's reflecting on number plate then getting white wash, and unable to read any number on plate, as showing in below picutre.
Root Cause- The challenge is there are three major things,
1. With the software version V200R002C20SPC300, there was no option to configure to the camera for Day and NIght mode based on Lux level, either based on IR level. In such scenarion camera was working itself in same configuration 24 hours, so unable to change the configration of camera in different differnt mode, and same configuration can olny enable 24 hours.
2. There is no option with software verion V200R002C20SPC300, to create multiple profile to adjust the video quality as per required environment like day and night.
3. Wrong Configuration for night Time
1.Upgrade to all the camera on tafgete version -IPCV200R003C20
In this version finding multiple features which is not available in the previous version.
2. Creating the Profile for Day and Night time separatally manually.
Configure the Profile based on environment requiremetns.
Day Profile Configuration-
For ANPR case recommend to install the camera in proper place and FOP should be very clear and vertical instead of tilt installation. AS well must be use to the recommended configuration to get the best result.
