● CONNECTING WITH OTHER DEVICE
Connecting the camera
Use the coaxial cable to connect between DVR and HD-SDI camera as shown.
•
Auto setting of the 75 terminal resistor
The 75 terminal resistor is set by default. If the resistor is connected to the video output port under the video
input port, it will be disconnected and switch to the Hi-z condition.
•
The video type entered will be recognized automatically when the DVR gets started.
Starting with camera 1, the DVR will recognize the cameras for all channels available. The priority will be
determined depending on the signal type of the camera searched first.
M
There is no limit on the number of channels available if they send camera videos in the same resolution. However, if different
videos in 1080p and 720p are received simultaneously, channel 1, 2 should receive the video in 720p while channel 3, 4
should receive the video in 1080p. Otherwise, the video will not be played properly.
Recommended Cables
•
5C-FB(T), 5C-HFB(T), L-5CFB
•
L-4.5CHD, L-6CHD : HD-SDI specific cable
•
Belden : 543945 RG59U, RG-59/U 1505A, RG-6/U 1694A
J
The transfer distance of a cable may differ depending on the damping rate of 750MHz. (An attenuation rate of dB/100m <
25dB is recommended.)
It is recommended to use foaming or high-density foaming insulation.
The dual- or triple-shield cable is recommended.
For recommended cable specifications, refer to KSC-3617, domestic standard (5C-FBT) and RG-6/U.
DC LOOP resistance of 31.3Ω/km or lower is recommended.
When extending coaxial cable and attaching connector, make sure to use parts of 75Ω impedance.
Pay attention to cables when working, to avoid cable deformation by pressure.
When cabling, do not apply excessive force with pulling.
When cabling I/O cables on rear side of the rack, take care not to bind the tie too tightly. Otherwise, cable’s internal/external
insulations may be deformed when the cable is twisted after binding. Allow a cable-thick gap when binding ties. Be careful
not to bend the cable over its curvature radius.
The maximum transmission distance of HD-SDI may be affected by the cable manufacturer and installation conditions.
CONNECTING TO AN EXTERNAL STORAGE DEVICE
The USB port is designed to use the USB storage device for simple copying (less than one hour in data size). If you
want to use an USB device, the specifications of the USB device should not exceed the following specifications.
eSATA Port
The DVR introduces eSATA as an interface with the external storage device, which provides one eSATA port on
the rear panel.
By taking advantage of the internal HDD and eSATA port, you can install up to 12TB storage device.
M
The eSATA port supports only Samsung Techwin-manufactured external HDD (SVS-5R).
