Fully Functional Recording
• Flexible Recording Schedule: Once cameras have been set up, a highly configurable scheduling system
allows for continuous recording or recording during specifically allotted time frames. Each camera can be set
to record independently at preset intervals. It also provides event recording based on specific triggers.
• Recording Automatic Overwrite: The NVR can be configured to overwrite the oldest data automatically
when hard disk space runs out, allowing for continuous and uninterrupted recording.
• Recording Stop Alert: The NVR also provides the option to stop recording when the hard disk is full. When
the disk reaches capacity, a notification can be sent via e-mail and audible alarm.
Comprehensive Data and Security
• Auto Boot after Power Recovery: The NVR will boot up automatically once the power is restored after a
power outage.
• Access List Control: Users can specify safe and blocked IP addresses to filter external connections, increasing
data security.
• Multiple User Privilege Control: Administrators may also choose access privileges for users by specifying the
cameras they may have access to for live view, playback, audio, and PTZ functions.
• Backup Recording Data: Recorded data is stored in a secure database. This recorded data can be backed up
to additional storage locations periodically or whenever needed.
Flexible Event Management
• The NVR can monitor trigger events from all cameras, such as from motion detection. These can be used to
trigger e-mail notifications and recordings, all centrally handled by the NVR.
Instant Live View
