   --< Comparison Details >--  
             ~ Comparison against Thermal Camera, Laser Diode, Conventional IR Camera ~

           -- Night Vision markets are divided into 4 kinds of products, that is,
                Thermal Camera, Laser Diode Illuminator, conventional IR Camera
                 developed for shorter distance, and one more is our Hybrid IR illuminator
                  developed for long/middle distance and it gives diverse satisfaction
                   covering the limited weak points of the above 3 competition products --

    = Thermal IR Cameras =

         * Object Recognition Method of Thermal Camera

             - All objects have temperatures higher than absolute temperature (-273¡É)
                and each object emits thermal energy corresponding to its temperature.
             - Thermal camera : Detect the energy difference of infrared rays area and
                convert it to electric signal, then capture images thru digital image process.
             - Image capture is possible even under no light zero darkness.
             - Application : Power plant, harbor, main important facilities, border area,
                                  war area, etc. where to detect invisible intruder, enemy, etc.
             - Normal IR high cost equipments for monitoring of longer distance
                over 300m and applicable mainly to special fields like military, etc.

         * Weak Points of Thermal Cameras 

             - When the object is at a longer distance, it is impossible to clarify between
                human and animal owing to shortage of analysis capability.
             - When the object has a rain-coat on, it is impossible to detect it at all.
             - The fog has lower temperature than the air, therefore it influences badly
                on recognition by thermal camera which is passive way of radiation.
             - Clean image realization is not possible at day time. Object recognition ability
                drops down deadly.
             - Meanwhile it is very expensive equipment.

    = Laser Diode Expansion Illuminator

    = Conventional IR Products - Short Distance

         * Conventional IR Camera Recognition Method

             - Active way of object recognition method by radiation of
                near infrared rays light even under 0 Lux illumination.
             - Excellent way of image capture even under foggy weather,
                although not so clean image as that of under clean weather.            

         * Weak Points of Conventional IR Camera

             - Clear images are available at short distance and the prices became
                competitive due to so many competitors, however covering only
                less than 100m of visible distances.
             - Infrared rays light has strong power only within 10m of visible distance.
             - In case even only one set of bulb (among several sets of giant bulb)
                is damaged due to currency overload, this damage does immediately
                influence all the other bulbs' life span into very short life time.
             - Power consumption rate is very high.

    = Conventional IR Products - Middle/Long Distance

             - The markets of IR Illuminators for Middle/Long distance, different from
                short distance markets, there are only two providers are available, i.e.:
                Bosch and Raytec.

         * Bosch

             - Line up of Long distance (till 700m) is prepared, with long history.
             - However the life time is very short, average 2,000 hours only
                on account of high power consumption & heavy overload.
             - Meanwhile the prices are comparatively very high, especially
                considering its short life time.
             - Main components are not self-developed but supplied from sub-suppliers,

         * Raytec

             - Life span is said to be longer than Bosch and prices came down.
             - However still Life time is shorter, hence price is relatively higher..
             - Main components are not self-developed, but supplied from sub-suppliers,
                thus maintenance takes time, etc.

    = Our Hybrid IR Illuminator / Camera

             - We have main component, Hybrid IR Chip, developed by ourselves.
             - Our technologies are resulted in Low Power Consumption, Semi-permanent
                life time, Economical & Scientific Structural Improvement.

         * Functions & Efficiency

             - Compared with Thermal Camera or Laser Method, we have adopted
                LED Chip Method with specifically high radiation energy, therefore
                the Transmission Rate is higher than conventional LED Chip, and
                consequently the more higher capability is showed even in foggy weather.
             - It is developed for longer distance projection, thus over 300-500m of longer
                distance illumination is possible, which was not available by existing ones.
             - Simultaneously with light collection, wide beam angle projection is possible
                within the illumination area.

         * Semi-Permanent Life Time

             - We have Light collection type Single LED, not Giant Bulb, thereby we realized
               very scientific way with Chip Life Time guarantee for over 10 years.
             - Structural design of real time radiation.
             - There is no thermal transfer rate each other in basic design, so no bad influence
                to other components with shorter life time like other conventional IR products.

         * Economics

             - Remarkably low power consumption rate, compared to the conventional IR cameras
                which require high power consumption & high facility cost.

         * Applications

         * Unique Technology

             - Long distance IR Illuminator manufacturing with Own development of Hybrid
                IR Chip is our Unique technology with the most competitive capability.
