UNV NVR (16 Channel, PRO)

This recorder has the following special features:

AI (Artificial Intelligence)

AI allows the NVR to work out if the movement detected was caused by a human, vehicle, or nature. This requires an AI compatible camera (order code ending in -I0).

ANR (Automatic Network Replenishment)

ANR is a feature which allows a camera to record to an onboard MicroSD card, if it loses connection with the NVR. Once the connection has been re-established, the footage is transferred to the NVR. This feature requires ANR support from the camera and NVR.

Fisheye Dewarping

Dewarping is a feature which allows an NVR to dewarp the 360° image from a fisheye camera. This makes the image much more usable as the image is flattened and not warped.

LPR (License Plate Recognition)

LPR is the ability to automatically analyse video to detect vehicles and number plates. This allows the NVR to record footage as normal, but also record and store license plates. This is done using the Uniview LPR camera (HC121@TCR-08S-Z).

RAID (Redundant Array of Independent Disks)

RAID is a data storage technology that combines multiple hard drives into one or more logical units. The purposes of this are data redundancy, performance improvement, or both. This NVR can perform the following different configurations of RAID:

• RAID 0 - Combining all hard drives into one "logical" drive. This configuration gives higher speed, the most amount of usable space, but with no redundancy. If one drive fails, all the data will be lost.
• RAID 1 - Data is written to each hard drive, creating a "mirrored" set of drives. This configuration provides the least amount of usable space, but with redundancy. If one drive fails, no data is lost.
• RAID 5 - This requires at least 3 hard drives to work. This configuration provides a medium amount of usable space, with redundancy. If one drive fails, the unit will assess the missing data and rebuild it. Any more than one failed drive (at any one time) will result in total loss of data.

VCA (Video Content Analysis)

VCA is the ability to automatically analyse video to detect temporal and spatial events. The feature requires VCA support from the camera and NVR. This NVR has the capability to do the following:

• Audio Detection - Detect a sudden increase or decrease in sound
• Crowd Density Monitoring - Detect and monitor the number of people in a pre-defined virtual region, with different warning levels
• Enter Area - Entering into a pre-defined virtual region
• Face Recognition - Detect and recognise faces against a known database
• Fire Detection - Detects fire (requires a thermal camera)
• Intrusion Detection - Entering and loitering in a pre-defined virtual region
• Leave Area - Leaving a pre-defined virtual region
• Line Crossing - Detect when a pre-defined virtual line has been crossed
• Motion Detection - Movement within a pre-defined virtual region
• People Flow Counting - Counts the number of people crossing over a virtual line
• Object Left Behind - Detect when an object has been left inside a region, which wasn't there before
• Object Removed - Detect when an object has been removed from a region, which was there before
• Scene Change - Detect when the scene changed
• Smoking Detection - Detects smoking (requires a thermal camera)
• Tamper Identification - Detect when the camera has been physically tampered with
• Temperature Measurement - Measure temperatures (requires a thermal camera)
• Ultra Motion Detection - Detects if movement was caused by a human, motor vehicle or non-motor vehicle
