Full-featured Recording
•
Flexible Recording Schedule:
Once cameras have been set up, a highly configurable scheduling system allows for continuous
recording, set recording during specific time frames, or recording only on motion detection. Each camera can be set to
record independently in their own modes. Event recording based on specific triggers is also supported.
•
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 an audible alarm can be sounded.
Comprehensive Data and Security
•
Auto Boot after Power Recovery:
The NVR will boot up automatically once 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.
• RAID Mirroring:
RAID 1 hard disk configuration mirrors recorded data onto two separate hard drives. In the event of HDD
failure, data integrity is maintained on the secondary HDD.
