  • HVD-100  HD Level Video Enhancer (DVI type)




  • HVS-100  HD Level Video Enhancer (SDI type)




HVD-100 and HVS-100 are the High Definition Video Enhancer for DVI and HD-SDI.
They make images deteriorated by fog, dust, and other elements sharper, clearer, and brighter for improved visibility – optimal for highway, airport, harbor, and perimeter monitoring. They improve the visibility of videos deteriorated by fog, low light and other adverse conditions.
Cameras with defog function and software-based defog products are unable to provide the quality required in the field.
Oculen HVD(HVS)-100 is the solution you need.


√  Optimal video correction conditions based on the world’s first application of fully auto mode fog removal        – automatic selection of 256 levels of filtering depending on fog density
√  High-performance FPGA solution with exclusive HD level fog removal algorithm
√  Automatic detection and correction of night image without external sensors
√  Maximum suppression of noise with use of noise reduction filter
√  100% compatibility with DVI & HDMI
√  Outstanding improvement of visibility deteriorated by fog, rain, yellow dust, smog and low-light

  Application to usual places 

When there is a heavy fog in usual places, our HD level video enhancer products can make you see better, clearer images. 

Blurry image of a pension and trees becomes clear.
Blurry image of a rocky mountain becomes clear.
Blurry image of people on the boat in the river becomes clear.
Blurry image of trees and bushes becomes clear.

  Application to important facilities

In important facilities which need continuous monitoring for safety, our HD level video enhancer products help your monitoring regardless of bad weather (heavy fog, mist, smog etc.)

Blurry image of a dam becomes clear.
Blurry image of an airplane in the airport becomes clear.
Blurry image of a harbor becomes clear.
Unseen moon and racks of the buildings appear.
Blurry image of apartments and a construction site becomes clear.

  In case of heavy fog, it is especially difficult for general CCTVs to distinguish objects.

For continuous monitoring regardless of weather condition, HVD-100/ HVS-100 is necessary.

  Enhancement of Night Scene is also available

HVD-100/ HVS-100 Video enhancer automatically determines the degree of darkness based on analysis of image from the camera without external light sensors. Then it  makes the correction to improve visibility.

Unseen people at night can be seen.
