ROI (Region of Interest)
A region of interest is a specified part of a CCTV camera view that is highlighted and broadcast to a separate stream from a camera.
Usually a feature on higher mega pixel IP CCTV camera's, this technology uses the definition and resolution of mega pixel IP camera's to allow a digitally zoomed in section of a camera's view to be broadcast on a separate stream whilst still retaining the original overview from the camera.
This feature is great for highlighting area's such as doors or areas of access where an overall scene view is still required.
When using ROI in conjunction with an IP recording system you will require an additional channel for the ROI stream to be displayed and recorded on.
