Overview of the Visionhitech’s UHD 4K IP camera

VNV23LU4AR is an Ultra High Definition (UHD) 4K IP camera with Super sensitive low light image sensor and with 2.7~13.5mm motorized Varifocal Lens that has an enlarged 5x optical zoom ratio.

Powered by the UHD resolution and 5x optical zoom function, the camera can magnify the long-distanced scene without losing the details of micro-sized objects, enhancing the usage of video data much more efficient and accurate. As the entire objects within the 4K image quality highly usable, one single camera can target much wider and longer range of surveillance area, replacing the needs of multiple numbers of conventional cameras.

The VNV23LU4AR is armed with the excellent data streaming technology that reduces the size of transmission bandwidth to smaller than 20% compared with conventional streaming technology.

With all these high-profile features, the VNV23LU4AR has professional protection technologies embedded to withstand against high temperature and harsh environments.

TECHNOLOGY

Ultra STARLUX technology

See-through the 0.1lux darkness in full Color/ ‘0’lux in BW IR

The Ultra-Starlux camera comprises of an ultra-sensitive Stavis sensor, high-end ISP, and Visionhitech’s advanced video tuning technologies.

The technology allows the camera to conduct low light performance by 50% higher than the STAVIS camera and to capture live color video in as low as 0.1 lux darkness. At below 0.1lux, the camera turns to True DN mode that displays B/W image with the IR illumination on automatic.

The lux value of the 0.1 may refer to the darkness level of the mid-night after the sunset. At this range, the human eye loses its sensitivity to recognize the scene.

Ultra-Starlux technology enhances the colorful images taken into the camera more vivid and bright so that the details of objects that were indiscernible with the naked eye or with B/W IR mode be distinctly identifiable.

TECHNOLOGY

Ultra-Smart Rate Control

A new breathtaking video streaming is born to adopt here. We would like to differentiate it by calling it an “Ultra Smart Rate Control (USRC)”.

The efficiency of the data saving rate surpasses the performance of the conventional Smart Bit Rate control (SBC) by around 80% lower in comparison.The flexibility of controlling the bit rate in a scene, enables the camera to produce the most usable high-quality video data while reducing its bandwidth.

The area of the interest selectable conducts the process in the highest bit rate and the other area as low as possible, leaving the background images still alive. This revolutionary video data streaming technology brings an enormous amount of cost savings in the full-HD video network streaming and storage management while utilizing full HD Video at full frame in most of channels.

TECHNOLOGY

Advanced Region of Interest (ROI)

The Advanced Region of interest (ROI) feature greatly improves the usability of the streamed images by increasing the video quality in the areas of interest and by leaving the other areas with less compressed images (The less important background images are still alive) resulting in the image quality within the ROI area to be more clear. As a result, the advanced ROI significantly decrease the file size to minimum, granting great amount of cost saving in data transmission and storage management.

Quick & Precise Auto-focus & Zoom

Extraordinary image quality with the magnificent focusing technology!

As the camera’s megapixel numbers are rapidly growing higher, it became almost impossible to focus the camera exactly with manually vary-focal lenses. Furthermore, even the ordinary motorize lens focus method is also facing its limitation by the lack of accuracy.

Visionhitech solved this problem by empowering the camera itself to find and set the exact focal point almost immediately by successfully combining its own Autofocus zoom camera algorithm with the motorized lens. Now customers can view highly accurate megapixel images at even zoomed-in focus without losing its resolution.

With the angle-of-view adjustment and focusing remotely controllable at the control center, it is now no longer required to go through the big hassle of focus setting at the installation.

When the camera’s angle of view needs to be changed later after the installation, it’s adjustable at the center with one click of the mouse by the security manager with no need to deploy people to the site, which can bring tremendous time and cost savings in terms of installation and operation.

NDAA Compliant!!

The design and manufacture of the product are of Korean origin and fully comply with the NDAA protocol.

TECHNOLOGY

True Day & Night

ICR filter mechanism is adapted on it to safeguard the True Day & Night image quality. Unlike human eye, the camera sensor can see the infra-red light and distorts the coloration in day light. ICR (Infra-red Cut-off Removal) filter that is mechanically placed on to the sensor blocks the IR light. In night or dark light condition, the IR Cut filter is removed in order that the camera can receive the IR reflected light. The ICR mechanism also contains Focus Shift Compensation filter to provide precisely focused images for 24/7.

TECHNOLOGY

Real WDR (120dB)

In general, there are scenes of highly contrasted areas coexisted in a scene in the bright sunny day. Normal camera without WDR function artificially forges the whole image as one scene and makes the images of bright areas brighter and the dark areas more darker resulting in the image details within the scene indecipherable.
The Real WDR in the camera allows each aspect of the long exposure (bright area) and short exposure (dark area) in a scene captured accurately.

TECHNOLOGY

Smart IR

Smart IR technology automatically controls the amount of the IR illumination according to the distance of the object, resulting in producing recognizable images at night without the human face being washed out.
