5.0/5 rating (3 votes)

NS4025V5-A is a professional security camera which is designed for high-end commercial video surveillance. This camera leverages the industrial leading hardware design combining with Hisilicon top-rank SoC and OminiVision CMOS image sensor. This camera is able to deliver you the crystal clear 4-megapixel resolution video, which upgrade your video surveillance system to a higher level. 

Key Features

  • Professional camera for commercial video surveillance projects
  • Hisilicon Hi3516A + OmniVision OV4689 HDR CMOS
  • 4MP/3MP real-time video
  • 2.8-12mm vari-focal or motorized zoom lens (optional)
  • 128GB on-board storage via USB port
  • Audio I/O, alarm I/O, analog video BNC output
  • Smart IR, 30 meters IR range
  • Vandal-proof and weatherproof design
  • ONVIF Profile G, Profile S
  • DC12V, or PoE 802.3af (optional)

High image quality with 4MP/3MP resolution

The camera’s core processor is the Hi3516A, this is the best and costly SoC for IP camera from Hisilicon H.265 portfolio.  Incorporating with the OmniVision OV4689 HDR image sensor, the camera is able to offer 4MP(2592x1520)@30fps video capturing capability. Being compatible with H.265 and H.264 video compression standard, the camera can be used for your top-notch H.265 IP video surveillance system or existing H.264 system.

Intending to provide day&night surveillance, the camera has 36 pcs Infrared LEDs, unlike the conventional IR, it uses 950nm wavelength infrared, therefore can minimize the IR glow problem. These IR can provide wide angle and up to 30 meters illumination coverage. By the way, it also offers Smart-IR technique to avoid IR over-exposure problem. A IR-CUT filter is located between the sensor and the lens, a filter will switch on to block unnatural rays, therefore allowing the camera to capture vivid color video with true color reproduction.

Advanced IP Cameras for Commercial Projects

There are many unique features the camera can support such as 2DNR, 3DNR, BLC, HLC, Corridor mode, Lens Distortion Correction, Motion Detection, Privacy Mask, Smart Video Analytics, ROI Encoding and more.  Furthermore, it comes with rich peripheral design including alarm I/O to make system integration become easy and possible, audio I/O to support audio monitoring, while video plus audio sync recording and 2-way audio intercom can be achieved too. In addition to relying on network video recorder for video recording, it has a USB port to support on-board video storage, in case encountering network disruption or disconnection, you will not loss the footage. 

Manual or motorized 2.8-12mm Lens

Despite the image resolution, this is an advanced camera has a 2.8-12mm vari-focal lens to enable users to adjust the field of view. It also has the option to use a motorized zoom lens, therefore the camera can automatically adjust the viewing angle, and cooperating with fast auto-focus to obtain clear view in different installation scenarios.  We recommend users to choose using Power over Ethernet technology, which can make the installation more easier and greatly reduce the installation cost.
