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 16CH & 8CH Models

Step1: Loose the screws on the upper cover and open the upper cover of the DVR.

Note: The DVR cover is made of metal. Please be careful with its edge when you remove the cover.

Step2: There are two HDD brackets for this DVR as indicated on

the right picture.

2-1 To install on the first bracket

Remove the bracket, and align the screw holes of the

bracket with the HDD’s screw holes. Make sure the

PCB side of the HDD is facing up.

Fasten the HDD to the bracket, and connect the power

connector and data bus connector to the HDD. Then,

replace the bracket to DVR.
