Dahua 4in1 1080P 2.8mm IR PoC HD CVI Bullet Camera

POC - POWER OVER COAX:

This new technology makes it possible to power common coaxial cameras directly through the video cable, on which the signal is sent using the same transmission medium. This technical concept is very similar to PoE, already widely used on IP devices and even earlier on old analog telephones.

The coverage in terms of distance of this technology depends on the quality of the cable and the power supply required by the camera, in any case the guaranteed distances are greater than those of the typical 12V power supplies, which have a much greater loss.

Below you will find a purely indicative table of Dahua:

2MP resolution, means 5 times the resolution of a common D1 camera:
Max 25fps @ 1080P Remarkable flui dity .

1 / 2.7 "CMOS image sensor

IR illuminator with 18 SMD LEDs (Surface-Mount-Device, new generation LEDs.

ADVANTAGES:

• - High brightness
• - Reduced energy consumption
• - Small size
• - Long duration

OSD (ON SCREEN DISPLAY) allows you to define masked areas, image correction, ATR, Day / Night sensitivity, Shutter speed, White balance, light compensation and much more ...

The OSD menu is multi-language

Multi-Technology:

The camera can switch from HDCVI to HDTVI, AHD or Analog via the OSD Menu or UTC controller (not included).

It allows to adapt the lens to the night / day vision and the consequent management of the IR illuminator automatically.

THE IR CUT FILTER IS A MECHANICAL FILTER THAT ALLOWS A CORRECT DISPLAY OF IMAGES IN DAYLIGHT VISION CONDITIONS, FILTERING THE TYPICAL INFRARED FREQUENCIES, THUS IMPROVING THE IMAGE QUALITY. IN NIGHT CONDITIONS THE FILTER IS REMOVED AS IT IS NECESSARY TO CAPTURE THE TYPICAL IR FREQUENCIES.

AGC is an integrated signal amplifier that allows viewing even in critical conditions. It is automatic and does not require specific settings.

BLC (Back Light Compensation): it is one of the 3 possible steps in the management of images with contrast, typical situations are: entrances or exits from parking lots, license plates, special lights, entrances with shots from the inside out, etc. Light compensation is one of the most complex operations possible, the BLC function allows a discreet adaptation to these situations

D-WDR (Digital Wide Dynamic Range) is the Software solution of the most powerful WDR integrated in the DSP, exactly as it happens for the digital zoom compared to the Optical Zoom, it is a software simulation of emulation of the WDR technology, however extremely useful in circumstances of strong contrast.
