We promote a new generation of professional license plate camera DV-853

1, With a 9-22mm auto iris adjustable len and 27pcs adjustable white light,so it

can reach 20m illumination distance ,it is more capable of license plate recognition

under different distance and different light,it is easier for application and

debugging of agents,

2,The camera is designed four speed identification model, it is 100 km high-speed mode - This mode is suitable for license plate recognition in high-speed traffic environment, such as urban road monitoring or faster speed place ;

50 km medium-speed mode - for the streets or urban highway;

Standard Mode (15 km model) - and this model features is nearly same as general infrared camera, taking account of vehicle license plate identification and monitoring of the environment,it is recommended to only use it in the slower speed of gate crossings;

Intelligent Strong Light Inhibition Mode (default mode)—It is applicable to license plate recognition and environmental monitoring below 35km , this model is our original Intelligent mode, when car goes into the identified area,the camera automatically opens light suppression function,when car left,it automatically closes light inhibition and return to normal monitoring status,which takes account of  the needs of the surrounding environment monitoring, especially for residential entrances ,parking lots in the low-speed driving situations!

3,MCU intelligent analysis circuit control, outstanding effect of license plate identification at night ,clear and nice image in the day ,it will not cause dark image because of electronic shutter open in the day .

 

●Technical  Explanation :

The third generation of professional license plate color camera, an innovative light suppression function .

MCU intelligent analysis circuit control, outstanding effect of license plate identification at night , clear and nice image without dark image in the day.

In view of license plate reflective features,it adopts white light LED fill light,able to identify license plate number and background.

Four speed selectable modes, able to meet up to 100km / h high-speed capture.

With a 9-22mm auto iris adjustable lens , meet the different distances vehicles monitoring .

27 Φ8 white light, the brightness can be adjusted by using environment, supporting range up to 20 meters.

Using light sensors CDS, it is reasonable control of LED lights on and off, and

with a delay control circuit, to prevent repeated movement due to light interference;

Double-glass design, avoid fog, reflection and leaky phenomena.

110V-220V AC power, built-in fan and heater (optional), able to adapt to high and low temperature environment, stable performance;

Side open housing to adjust speed identification mode, the lens depth of field,

LED brightness, etc.;

Apply to entrances and exits of parking lots , highway toll stations, districts and

the place where need to monitor vehicles access in the day and night .

Technical Parameter

 

Technical points:
1, The day effect of four models is like ordinary cameras, 100KM model is relatively dark at night,50km model is brighter relative to 100km mode, standard mode (15km) apply to the entrance of road barrier, brightness is the best at night . Light suppression mode (35km) is wide application compared with other models,it is between 50km and 15km and factory set to this mode.

2, In the practical application of the process, customers often come across icense plate image white or dim which led to the problem of poor identification effect, this phenomenon mostly caused by brightness of fill light doesnot match, should adjust VR1 knob in the control panel to reach best recognition of license plate.
3, If identify the high-speed vehicles and monitor the surrounding environment, advise clients to install additional cameras, it can get better effect by two cameras.
