ONVIF
A common term you may come across in the IP Video industry is ONVIF. ONVIF is an acronym standing for Open Network Video Interface. ONVIF Forum is both a global forum and a global protocol, that allows different surveillance and security devices from different manufacturers to operate together seamlessly.
WDR
Wide Dynamic Range (WDR) technology improves a camera’s image quality under high-contrast lighting conditions where both dimly and brightly lit areas are present in the field of view. It enables the camera to capture details clearly in both the poorly and strongly illuminated areas of the video.
The video taken under such high-contrast lighting conditions is extremely important for security applications, such as the identification of people or vehicle license plates. Using a camera with strong WDR performance allows it to clearly capture detailed features by appropriately exposing both the darkest and brightest parts of the entire scene. WDR technology are particularly recommended for environments such as building entrances, ATMs, and transportation facilities and near windows with similar areas.
DNR
DNR which stands for Digital Noise Reduction is an image processing technique which aims is to eliminate the visible noise from an image. This technology is great for when you want to improve image quality when in low light settings and lower bandwidth, saving you storage. It makes images clearer and reduces video file size.
ROI
ROI (Region of Interest) in IP cameras allows focusing on providing the highest quality image for a selected region only. The remaining part of the image, outside the region is recorded at lower quality or not recorded at all.
IR range
IR distance is most important issue to select the camera to capture the range of areas. This range is a largely made-up number based on how far away from the camera Infrared light can be detected.
EXIR
EXIR stands for Extended InfraRed. Extended InfraRed, a technology that improves the security camera visibility in dark environments. The technology uses lights in order for the camera to see at night. What makes it different from just lighting up the area with flood lights is that infrared technology is not visible to the naked eye.
OSD
OSD stands for On-Screen Display. It is an integrated on-screen menu, that can be accessed within the camera to change its functions that effect how the camera processes an image.
