5.5. VOICE INTERCOM
5.5.1. SUMMARY
The Voice Intercom function enables the DVR bidirectional communication: The User can talk and
listen using the provided remote client software or over the Web via the DVR
’s audio input and
output ports.
There are two types of bidirectional communication, sharing and standalone. These vary by model.
Please refer to your DVR specifications to determine which is supported for your model.
5.5.2. CONFIGURATION
Local Configuration
Connect a microphone to the MIC input port and connect a pair of speakers to the audio output port.
If there is no standalone MIC input port, please connect a microphone to the Number 1 audio input
port.
Note: The audio needs to be connected to a powered audio output device.
Remote PC Configuration
Connect a microphone and powered speakers to the computer.
Enable bidirectional communication in the client software or the Web interface.
5.6. HARD DISK REDUNDANCY
The hard disk drive (HDD) redundancy function can backup recorded files. The User can then
retrieve files from a redundant HDD if a single HDD is damaged. This enhanced system data safety.
The HDD redundancy function performs a double backup of data from the designated channel to
the HDD, so the DVR needs a standalone hard disk for the redundancy function to be effective.
Hard Disk Redundancy Configuration
Open the Main Menu and then the Storage menu to access storage configuration. Select an HDD
as the redundant drive, and then click on Setting.
The Redundancy HDD must be an independent drive. The User can set several hard disks as a
redundancy HDD group. Once an HDD is assigned as a redundant HDD, recorded data can be
saved to both the main HDD and the redundant HDD.
The data on the redundant HDD should be automatically cycled; the cycle period depends on the
recording data and the capacity of the redundant HDD.
Note
: Make sure there are two HDDs, with at least one in the DVR. One is for read and write
and the other for redundancy.
