INSTALLING THE CAMERA
The SD series cameras are carefully packed to prevent
damage during transport. First of all, it is necessary to
check the material received. The speed dome camera
you purchased is protected by packaging elements that
must be carefully removed before using it.
Realization of the wiring
with RS485 command
A cable with the following connections comes out of a
SD series Speed Dome camera:
112VDC power supply with 5.5 mm plug.
Video output BNC female
2 Cables BUS RS485 YELLOW (A +) / ORANGE (B-)
To structure a system of Speed Dome cameras, 3 types
of cabling must be provided:
Supply. It is possible to power the camera locally
with a 220VAC / 12VDC adapter of at least 3A (not
supplied) or set up a 12VDC network with cables of
adequate section in order to avoid excessive voltage
drops.
Video connection. It is realized as for any
traditional analog CCTV camera. The video signal
produced by this camera can be set to CVBS or AHD /
CVI / TVI composite video depending on the DVR to be
connected to, but there are no differences in the type
of wiring of these two technologies. In general, RG59
coaxial cable is used for distances up to 2-300 meters.
It is also possible to carry the video signal on twisted
pairs using special converters (RE-BNCRJ1) up to about
200 m. The twisted cable converters are also available
in an active version to reach distances greater than 200
m.
Telemetry.This is the serial connection that leads
the movement commands to the camera. The SD series
cameras use an RS485 serial line (RS485 BUS) which
must be made with a pair of twisted cables. It is
essential that the 2 cables are wound together and not
parallel. In theory, the RS485 serial line can extend up
to 1200 meters in length and the devices are connected
in cascade along it. The section of the cables strictly
depends on the length of the connection: for medium
distances a section of 0.5 mm is sufficient, while if it is
necessary to reach considerable distances (max. 1200
m.), Upper sections of 1 mm or even 2.5 mm must be
used. When wiring, it is advisable, but not essential, to
use shielded cable. The CAT5 network cable,
The cameras and consoles must be connected in
cascade or by entering and leaving the 2 terminals
RS485A and RS485B. It is important not to invert the
two cables (AB) when connecting the equipment.
The order in which the equipment is connected to the
BUS is irrelevant. Each appliance will be identified by
its own unique address, which can be set by means of
microswitches, which will allow instructions to be
correctly addressed. Up to 256 cameras can be
connected to the same BUS. The consoles do not
require any addressing, while for the cameras it is
necessary to set a different address for each camera,
as described below.
Wiring with UTC command
on video cable
If you have a DVR with UTC control, like our RK Series
DVRs, you can send the commands to the camera on
the video cable without having to wire the control pair.
To use this command, UTC must be selected as the
protocol in the NVR instead of Pelco D. The RS485
connectors are left unused.
Note that if the camera receives commands via UTC,
some functions may not be usable with respect to the
RS485 connection.
Command bodies
The movements of these cameras are controlled
through the common PELCO P / D protocol, now a
consolidated industry standard. It is possible to send
the commands with the appropriate consoles for speed
dome cameras or via the DVRs equipped with RS485
port.
DVRs with UTC command can control these motorized
cameras with only the video cable
Address, protocol and Baud
Rate
After connecting the camera, it is necessary to set the
communication parameters so that it is able to
communicate with the control elements.
All the elements of the RS485 BUS, both cameras and
control devices must use the same protocol (PELCO D
