4.2. HDD Installation
Check the settings:
Before installation, please read carefully the recommendations below as high internal temperature of the
product can lead to damages and shorten the product’s life cycle.
Recommendations on installing a NVR/DVR in a rack:
Do not seal the inside of the rack where the NVR/DVR is installed. Keep the airflow through the inlet and outlet.
If there is another device installed in the rack, secure the additional space or install an air ventilation. Installation
of an air circulation fan around each inlet and outlet is strongly recommended. (Install the filter for harmful
substances around the inlet or outlet.)
Keep the ambient temperature between 5°C~45°C around the NVR/DVR.
English
Warnings if a HDD is installed:
)
Please be extra careful not to damage the HDD as it easily breaks.
During installation, make sure the insulated coat does not come off or is not placed in the wrong place. Do not
lose screws and parts. (If screws and parts are not screwed or assembled correctly, the product may not operate.
Check the HDD compatibility list.
The Partition table must be removed for the HDDs previously used in a PC or other DVR models before
installation.
Before you start:
Disconnect the power from the NVR/DVR before installing a hard disk drive (HDD). A factory recommended HDD
should be used for this installation.
Up to 8 SATA hard disks can be installed on your NVR/DVR.
Tools required:
1 Screwdriver.
1. Remove the cover from the NVR/DVR by unfastening the screws on the rear and side panel.
2. Connect one end of the data cable to the motherboard of the NVR/DVR and the other end to the HDD.
3. Connect the power cable to the HDD.
English
4. Place the HDD on the bottom of the device and then fasten the screws on the bottom to fix the HDD.
5. Re-install the cover of the NVR/DVR and fasten the screws.
4.3. Peripheral Connections
Wiring of the Alarm Input / Output:
The alarm input is an open/closed relay. To connect the alarm input to the device, use the following diagram.
If the alarm input is not an open/close relay, please connect an external relay between the alarm input and the
device.
To connect to an alarm output (AC or DC load), use the following diagram:
For DC load, the jumpers can be used within the limit of 12V/1A safely.
To connect an AC load, jumpers should be left open (you must remove the jumper on the motherboard in the
DVR). Use an external relay for safety (as shown in the figure above).
There are 4 jumpers (JP1, JP2, JP3, and JP4) on the motherboard, each corresponding with one alarm output. By
default, jumpers are connected. To connect an AC load, jumpers should be removed.
Example:
If you connect an AC load to the alarm output 3 of the DVR, then you must remove the JP 3.
English
Alarm Connection:
To connect alarm devices to the DVR:
1. Disconnect the pluggable block from the ALARM IN /ALARM OUT terminal block.
2. Press and hold the orange part of the pluggable block; insert signal cables into slots and release the orange
part. Ensure signal cables are in tight.
3. Connect the pluggable block back into the terminal block.
RS-485 and Controller Connection for the models GRT-K1104A/GRT-K2208A:
To connect the PTZ to the models GRT-K1104A/GRT-K2208A:
1. Disconnect the pluggable block from the RS-485 terminal block.
2. Press and hold the orange part of the pluggable block. Insert the signal cables into the slots and release the
orange part. Ensure the signal cables are in tight.
3. Connect R+ on the PTZ to D+ on the terminal block and R- on the controller to D- on the terminal block.
Fasten the stop screws.
4. Connect the pluggable block back into the terminal block.
RS-485 and Controller Connection for the model GRY-K4416A:
English
To connect the PTZ to the model GRY-K4416A:
1. Disconnect the pluggable block from the RS-485 terminal block.
2. Press and hold the orange part of the pluggable block. Insert the signal cables into the slots and release the
orange part. Ensure the signal cables are in tight.
3. Connect R+ on the PTZ to T+ on the terminal block and R- on controller to T- on the terminal block. Fasten the
stop screws.
4. Connect the pluggable block back into the terminal block.
To connect a controller to the DVR:
1. Disconnect the pluggable block from the KB terminal block.
2. Press and hold the orange part of the pluggable block. Insert the signal cables into the slots and release the
orange part. Ensure the signal cables are in tight.
3. Connect T+ on the controller to D+ on the terminal block and T- on the controller to D- on the terminal block.
Fasten the stop screws.
4. Connect the pluggable block back into the terminal block.
Make sure both the controller and the DVR are grounded.
Termination Switch Operation:
The termination switch is placed on the mainboard instead of the rear panel. Open the upper cover and turn
on/off the SW switch if needed.
The termination switch is to connect the DVR with several speed domes, the bus topology can be adopted, which
means the speed domes are connected with each other via the R+ and R- of RS-485 serial interface. But due to
the impedance of 485 wire, the longer the wire is, the greater the impedance gets.
To avoid the signal reduction caused by the great impedance of long distance transmission, please connect two
120Ω resistors in the circuit: one resistor between the DVR and the nearest speed dome, and the other one after
the furthest speed dome.
Steps:
1. Turn on the SW switches on the DVR and the furthest speed dome.
2. Keep the other SW switches off.
The connection diagram and status of each SW switch are shown in the following figure.
English
5. Getting Started
5.1. Operation of the DVR
5.1.1. Remote Control
It is possible to use all functions of the NVR/DVR with the remote control. If several NVR/DVRs are set with unique
ID numbers, they can be controlled with one remote control.
English
English
5.1.2. Troubleshooting the Remote Control
NOTE: Make sure you have installed the batteries properly in the remote control. And you have to aim the remote
control at the IR receiver in the front panel.
If there is no response after you press any button on the remote, follow the procedure below to troubleshoot.
English
Setting the ID of the NVR/DVR:

3. Press the DEV button on the remote control.
4. Enter the NVR/DVR ID# you set in step 2.
5. Press the ENTER button on the remote.
If the Status indicator on the front panel turns blue, the remote control is operating properly. If the Status
indicator does not turn blue and there is still no response from the remote, please check the following:
1. Batteries are installed correctly and the polarities of the batteries are not reversed.
2. Batteries are fresh and not out of charge.
3. IR receiver is not obstructed.
If the remote still cannot function properly, please change the remote and try again, or contact your dealer.
