Wide dynamic range is a feature in some network cameras that handles a wide range of lighting conditions in a scene. In a scene with extremely bright and dark areas or in backlight situations where a person is in front of a bright window, a typical camera would produce an image where objects in the dark areas would hardly be visible. WDR solves this by applying various techniques to enable objects in both bright and dark areas to be visible.
IP cameras are also known
as network cameras. Most IP cameras come with built in POE, and they can connect to
the NVR's built in POE port. POE switch can also use. Some NVR's with built in POE are pretty much plug and play if
the camera is compatible, use third-party cameras if they have ONVIF feature. IP cameras are very
high in resolution, and a 4 MP IP camera
can be bought from us for $79 and up. If you are looking for a bargain and like
