Section 1 - Product Overview
• The SNMP consists of the following three key components:
• Manager: Network-management station (NMS), a server that executes applications that monitor and control
managed devices.
• Agent: A network-management software module on a managed device which transfers the status of managed
devices to the NMS.
• Managed device: A network node on a managed network. For example: routers, switches, bridges, hubs, computer
hosts, printers, IP telephones, network cameras, web servers, and databases.
Full-featured 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 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.
