Overview of the Visionhitech’s UHD 4K IP camera

VNV151U4AR 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.

It’s embedded with highly enhanced smart streaming technology reduces the size of data bandwidth by smaller than 20% compared with conventional streaming solutions.

The Anti-IR reflective dome bubble clearly solves chronical problems of the IR night-time image going blurry by the IR light reflection against scratches, dusts, snows or raindrops.

With all these high-profile features, the VNV151U4AR has professional protection technologies embedded to withstand against high temperature and harsh environments.

TECHNOLOGY

Perfect Anti-IR Reflection

See-through the dusty or rainy environments with no IR glares

Visionhitech developed a patented Anti-IR Reflection solution appliable to its bubble dome camera ranges.

This innovative solution perfectly isolates IR illumination from the image sensing area so that the IR illumination can never be interfered with environmental particles such as scratches, dust, smokes, raindrops etc.

In conventional dome cameras, even small environmental particles sticking on the bubble mirrors IR Lights back to the lens and makes the whole screen all white. This typical phenomenon has been accepted as normal and people tend to do the cleaning the bubble so often causing it to be more contaminated by more scratches.

In a disaster situation such as an accidental collapse of constructions, fires or heavy rain etc., if the scene is not properly captured due to the IR interference by small particles, the result can be very tragic.

Now, with this now solution, particles or stain of raindrops are not visible and not being mirrored by IR illumination anymore, guaranteeing 100% clear nighttime IR images all the time.

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.

TECHNOLOGY

Anti-condensation Sensor & Heater

In cold weather, the moisture existing inside the camera sticks on the surface of the camera lens or cover glass by the temperature difference between inside and outside. It happens even the density is minimal. This phenomenon is called “condensation”.
The Sensor & Heater solution detects and removes the condensation automatically. When the temperature goes down below the setpoint (e.g., below 0°C), it triggers the heater to dry out the condensation completely.
TECHNOLOGY

Smart Network status indication

This offers a great convenience for the process of the camera installation and maintenance. Customer can identify the status of power and network connection/disconnection simply from outside eliminating the hassle to dismantle the site after the finish of the installation or to remove the camera to diagnose the network or power failure for a maintenance.

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.
