With built-in long life IR light LED, it can get a distance of 70M at night. Some IR LED on the camera, some IR light LED on the housing, this make the camera get good IR view for both near and away.
Precise conductive slip-ring is adopted, with which pan 360° endless running is realized and all-direction monitoring effect is realized, cable-twisting problem as well as merely 355° pan problem which generally happen with common constant speed domes are effectively solved.
The operation is based on advanced stepper motors and driving circuits, which ensures smooth running, long time consecutive working, long lifespan and high reliability.
PCB board is very compact, most of the parts on the PCB board are highly integrated and modulized, thus the possibility of trouble is greatly reduced and the stability of the performance is ensured.
The design of the outer housing of the Constant Speed Dome Camera is reasonable, elegant and practical. The outer housing can endure long-term operation without distortion. And the installation of the unit is fast, convenient and more human.
The function of Position Limiting is realized with photoelectrical sensors, which avoids the limitations of traditional mechanical Position Limiting and switch Position Limiting (the lifespan of the switch is 200 thousand times ON/OFF).
Left/right limiting positions can be set up on the dome camera panel; it also can be set up through the keyboard in the controlling room, which avoids the limitations that the limiting positions can be only set up from the front terminals for common constant speed domes.
Running speed 12°/S.
The built-in PCB panel supports multi mainstream protocols, and many more protocols can be input according to the customer’s needs. The Baud rate is also adjustable.
The unit adopts DC14V (15V) power supply and separates from it the components that produce heat in the process of transformation, which prolongs the durability of the unit. The unit possesses the functions of anti-jamming and anti-crashing.
Two grades anti-lightening technology, which effectively improve the anti-lightening and anti-interruption ability
If the unit is carrying out scanning or cruising function when the power is off, it will automatically resume carrying out the function once supply of power is on after the power-off state.
Support 128 preset positions, 8 tours, left & right scan, 360° scan.
The unit has one default position; the user can preset the default position for a key monitoring area according to the actual conditions. If not operated after 5 minutes, the dome camera will automatically monitor the preset position.
With built-in fan and heater system, it will auto control the temperature of the camera. Auto turn on the heater will the temp below -5 and turn on the fan when the temp above 40 centigrade.
With 27 zoom camera, it can get a clear view of the car NO 100 meters away.
Diameter: 7inch, beautiful looking.
Remarks: The function of item 14 can be realized only when the protocol adopted supports the keyboard produced by this company. Also, the user can include our protocols into the DVR or existing software
