2. CONNECTION AND SETUP

Before the DVR is powered on, make sure you have installed a hard disk, connected at least one camera and a
monitor. For details, please refer to the following sections.
Note: The DVR is designed to automatically detect the video system of the connected cameras (NTSC or
PAL). To make sure the system detection is correct, please check if the cameras are connected to
the DVR and power-supplied before the DVR is powered on.
Note: The connection and setup described below are for DCCS devices only. For details about connecting
cameras other than DCCS ones, please refer to the DVR user manual.

2.1 Prerequisites

Make sure your cameras support the DCCS function. For details, please check with your distributor or
installer.
To ensure the signal transmission, the recommended distance between this DVR and cameras should not
exceed 200 meters by using 3C2V coaxial cables (112 braids).
However, different materials used in 3C2V coaxial cables with different connection distance may cause some
effects for the availability and fluency of signal transmission.
Therefore, please do the DCCS test as instructed in "2.9 Examining Signal Transmission" at page 5 when the
connection is completed to ensure this system can work normally.
It's not allowed to use a signal booster or modem to amplify signals and extend the connection distance.
The DCCS function doesn't support the channel which is looped from a DCCS camera connected to the same
DCCS DVR or to other DCCS DVR.

2.2 SATA HDD Installation

A SATA HDD must be installed before the DVR is powered on.
Note: It's recommended to clear all data in the hard disk when the DVR is powered on and the date &
time are set correctly to ensure the recorded data are not mixed with other data previously saved
in the same hard disk. For details, please refer to "2.7 Clear Hard Disk" at page 4.
For AVD748BD & AVD746BD
Step1: Loose the screws on the upper cover and open the upper cover of the DVR.
