The IK rating classifies the level of protection that electrical appliances provide against mechanical impacts from outside. It is defined by standard IEC 62262. The degree of mechanical protection is identified by a code that consists of the letters IK followed by two digits: Code Impact Energy Test 00 [...]
Normally, when a camera uses infrared LED arrays for wide area illumination at night, you may see the over exposure image when the object is closed to IR camera. Smart IR technology automatically adjusts IR intensity according to proximity, and eliminates object over exposure caused by strong illumination. Smart [...]
Surveillance cameras can be classified as indoor and outdoor models according to installation place. The main difference between two models is whether the camera is weather-proof or not. That is, outdoor camera does completely protect the inner material from weather like wind, rain, moisture, dust, snow, and humidity. Some [...]
DOF (Depth of Field) refers to the range of distance that the subject appears acceptably sharp. DOF is determined by several factors such as aperture size, lens to subject distance, lens focal length, and image sensor size. Generally, the following conditions result in a deep DOF. - small or [...]
ICR (Infrared Cut Filter) is used with color CCD or CMOS image sensors to produce accurate color images. During the day, the camera uses an ICR to reflect or block mid-infrared wavelengths while passing visible lights. However, as light diminishes below a certain level, some cameras can automatically turn [...]
IRE stands for Insitute of Radio Engineers, and represents the composite video signal in percentage terms. That is, 100 IRE equals 100% full signal level which means 714mV amplitude active video signal. Generally, 30 IRE is a minimum value for a detailed and acceptable image. Most cameras represent the [...]
