The HDCVI DVR supports only IVS or the additional IP channel inputs, both features cannot be in use simultaneously. IVS triggers an alarm and takes a defined action for the following events: Premium Features HDCVI DVR supports IVS features on only two (2) channels simultaneously. Each channel supports up to ten (10) IVS rules. Tripwire A target crosses a user-defined line. Intrusion A target enters or exits a defined perimeter. Abandoned/Missing Object A target leaves an object in designated area, or a target removes an object from the same designated area. 1. The DORI distance is a measure of the general proximity for a specific classification to help pinpoint the right camera for your needs. The DORI distance is calculated based on sensor specifications and lab test results according to EN 62676-4 , the standard that defines the criteria for the Detect, Observe, Recognize and Identify classifications. 2. Transmission distance results verified by real-scene testing in Dahua's test laboratory. Actual transmission distances may vary due to external influences, cable quality, and wiring structures. 3. The M-N resolution refers to technology that allows a 1080p HDCVI DVR to accept a video signal from a 5 MP or a 4 MP camera by sampling every other pixel on a horizontal line from the camera. The resulting recording resolutions are: 5 M-N: 1296 x 1944; 4 M-N: 1280 x 1440. Downloads: Data Sheet Quick Start Guide
