Description

4MP WDR IR Corner Network Camera

  • 1/1.8” 4Megapixel progressive scan CMOS
  • 1/1 Alarm in/out, 1/1 audio in/out
  • Max. IR LEDs Length 10 m
  • IP67 and IK10+50J protection
  • 2.5 mm fixed lens, distortion correction

Overview

System Overview

With advanced H.265 encoding technology, Dahua corner network camera has efficient encoding capacity, which helps to save bandwidth and storage space.

 

The camera adopts starlight technology, intelligent IR technology, and intelligent image analysis technology; and has waterproof function, dust-proof function and vandal-proof function, complying with the standards of IP67 and IK10+50J.

Features

Protection (IP67, IK10+, wide voltage)

IP67: The camera passes a series of strict tests on dust and soak. It has a dust-proof function, and the enclosure can works normal after soaking in 1 m deep water for 30 minutes. IK10+: The enclosure can stand the punch more than 3 times from a 5 kg hammer falling from a height of 100 cm

 

Invisible IR LED Illuminator ( 940 nm )

With 940 nm IR LED, the IR LED Illuminator of the camera is invisible to naked eyes.

 

Distortion Correction

With advanced distortion correction algorithm, Dahua Distortion Correction corrects the image distortion in both horizontal and vertical directions to be consistent with the actual situation.

 

Starlight Dahua

Starlight technology mainly applies to the environment of low illuminance, and it can provide clear colourful video. Even in the environment of ultra-low illuminance, the technology can guarantee a good image effect.

 

Perimeter Protection

With a deep learning algorithm, Dahua Perimeter Protection technology can recognize humans and vehicles accurately. In the restricted areas (such as pedestrian areas and vehicle areas), the false alarms of intelligent detection based on the target type (such as tripwire, intrusion, fast moving, parking detection, loitering detection and gathering detection) are largely reduced.

 

Smart ( H.265+ & H.264+ )

With an advanced scene-adaptive rate control algorithm, Dahua smart encoding technology realizes the higher encoding efficiency than H.265 and H.264, provides high-quality video and reduces the cost of storage and transmission.
