This symbol is intended to alert the user to the presence of important operating and
maintenance (servicing) instructions.
This symbol is intended to alert the user to the presence of uninsulated “dangerous
voltage” within the product’s enclosure that may be of sufficient magnitude to constitute a
risk of electrical shock.
INSTALLATION AND OPERATION
CAUTION: To reduce the risk of electrical shock do not remove the cover or back of this
unit. No user serviceable parts are inside.
CAUTION: To prevent electric shocks and risk of fire hazards, do not use other than
specified power source.
1. UNPACKING and HANDLING
Each unit is shipped assembled and factory tested.
Ensure that all accessories are removed from the container before discarding packing material
2. MECHANICAL INSPECTION
Inspect the front and rear of the equipment for shipping damage. Make sure the equipment is
clean, and no connectors are broken, damaged, or loose. If equipment appears to be damaged
or defective please contact your distributor or SecurityTronix at 1-610-429-1511 for assistance.
3. SPECIAL ATTENTION
a. The installer must comply with electrical safety standards. There must be sufficient
space between the camera’s power supply and video line and any high voltage
equipment and/or cables.
b. To help ensure the camera’s life and proper operation do not point the camera towards
the sun or strong light.
c. Do not install the camera in an environment where the temperature is above 122 F.
d. Do not install the camera near a magnetic field or a high-power motor.

g. Only use a dry cloth to clean the camera. If there is dirt that is difficult to remove wipe
gently with a mild detergent. Never use strong or abrasive detergents.
h. The included 24VAC at 3A power supply must be used. Using a DC or other incorrect
power supply will damage the camera.
i. Only qualified installers are allowed to install, test and disassemble the camera.
j. The camera is a low voltage product. If installed outdoors proper safety and lightning
grounding are required.
k. Before installing be sure the grounding, wiring, input power, voltage, DIP switches,
communication protocol and baud rate are correctly set prior to powering up and using.

ON and OFF are indicated on the DIP Switches to show the DIP positions.
PELCO-D and PELCO-P can be automatically recognized.
J7 pin = if jumpers 2-3 is short circuited, terminal connects to 120Ω resistance. If jumpers 1-2
short, terminal is not connected to 120Ω resistance.
To select the baud rate set switches 3 and 2 on the System Setup DIP Switch as described
above.
Camera Module Selection
The ST-PTZ550-27 uses the Samsung SDM-270
camera module although various other camera modules
may be compatible with the unit. The DIP switch
settings on the camera module’s PCB board are factory
set for the SDM-270 and are not to be adjusted by the
installer or user.
5. WIRING CONNECTIONS
a. Connect the power supply cable and communications cable to the AC24V and RS485
connections on the main board as shown above.
b. Connect the camera to the monitor with a 75 coaxial video cable.
c. Connect power supply’s AC plug to a suitable AC power outlet.
d. Make an RS485 connection between the camera and the PTZ controller. Ensure the
V2.0 06/13/13
connections at the PTZ controller and camera have the same polarities.
