Flexible Recording

Configurable recording options and schedule save HDD space and active monitoring time. The DVR monitors incoming video and can be programmed to record if motion is detected or if an alarm is triggered. The DVR can also be programmed to record on a schedule or at different intervals. Recording options and schedules can be set for each individual camera or copied to all cameras.

Spot Output

The DVR provides a spot output channel for a secondary monitor. This monitor allows the operator to view one monitor that is assigned to selected cameras or video inputs from high-security areas.

Smart H.264+

The Smart H.264+ video compression standard can reduce bit rate and storage requirements by up to 70%.


The DVR automatically recognizes the incoming signals of each attached camera without any setup.

Smart Search

Smart Search allows an operator to specify a region in the playback video to search for a motion detection event.

Intelligent Video System (IVS) Standard Features

IVS triggers an alarm and takes a defined action when it detects tampering with the camera, an error writing to an onboard microSD card, an error sending or receiving data over the network, and unauthorized access to the camera.

IVS Premium Features

In addition to the standard event triggers mentioned above, the DVR offers premium event triggers for one analog channel. For this channel, IVS triggers an alarm and takes a defined action when an object moves through any part of the scene, when a target crosses a user-defined line, when a target enters or exits a defined perimeter, when a person or object moves or obscures the camera, and when a target leaves an object in a designated area or removes an object from a designated area.

IVS Advanced Features

On the first analog channel, IVS detects and captures a snapshot of human faces appearing inside a defined area within a scene.
