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.
e. Do not mount the camera near a radiator or heater.

gently with a mild detergent. Never use strong or abrasive detergents.
g. A minimum 12VDC 1.2A power supply must be used. AC power cannot be applied.
Using an AC or other incorrect power supply will damage the camera.
h. Only qualified installers are allowed to install, test and disassemble the camera.
i. The camera is a low voltage product. If installed outdoors proper safety and lightening
grounding are required.
This symbol is intended to alert the user to the presence of important operating and
maintenance (servicing) instructions.

b. Connect the camera to the monitor with a 75Ω coaxial video cable.
c. Connect unshielded twisted pair (UTP) control cable between the camera’s RS485
port and the PTZ controller. Be sure wire polarities are the same at each connection.
The camera’s violet wire (A) is + positive and the white wire (B) is – negative.
d. Connect power supply’s AC plug to a suitable AC power outlet.
e. Adjust the lens direction according to the required surveillance area and environment.
5. FUNCTIONS and OPERATION
Configuring the ST-PTZMINI-540W
The ST-PTZMINI-540W’s control board has an 10-DIP switch used to set a number of
parameters including address, communications protocols and control protocols. Any
command used should conform to the target camera and that camera’s response should occur
only when it has been addressed.
Of the 10 DIP switches:
Switches 1, 2, 3, 4, 5, 6, 7 and 8 are for setting the camera address.
Switches 9 and 10 are for setting the communications baud rate.
Set Camera Address
The tables below indicate DIP switch settings for creating the camera’s address. “1”
indicates the switch is set “ON” while “0” indicates the switch is set “OFF”.

FUNCTIONS
The user can control camera and lens movement through the use of a PTZ Controller. Further,
the user can track the target or shift the view while the camera’s focal length can be adjusted
to the required view angle and target image sizing. Note although manual adjustment of focal
length is possible while the dome moves at a high speed, the ST-PTZMINI-540W allows for
automatic horizontal and vertical dome speed adjustment consistent with lens focal length and
zoom settings so no information is lost during camera movement.
Zoom Control
The user can adjust the image farther or nearer to acquire a panoramic view by use a PTZ
Controller’s Zoom - / Zoom + controls. The ST-PTZMINI-540W supports both digital and
optical variable focus. There are certain conditions whereby the camera may not be able to
auto focus:
The target is not in the center of the image.
The target is in bright light (e.g., neon light, spot light).
The target or object is moving too fast.
The target is a large, square monotonous object such as a wall.
The target is too dark or vague.
The target is too small.
Surveillance Functions
A preset position is the storing of a camera location parameter such as horizontal angle,
inclination, or lens focus in memory and transferring them to the camera when needed.
Recalling and transferring preset positions is done through the PTZ Controller. The
ST-PTZMINI-540W supports 128 preset positions.
Set Preset Positions
The ST-PTZMINI-540W supports up to 128 preset positions. Setting the preset positions using
a PTZ Controller is done as follows by way of example:
Move the joystick so the camera is on the location or image for the first preset point.
Push Preset button on the PTZ Controller and press number 1 and ENTER for Preset
Position #1.
Move the joystick so the camera is on the location or image for the second preset
point. Push Preset button on the PTZ Controller and press number 2 and ENTER for
Preset Position #2.
Continue the above steps for each preset position to be entered.
To move the camera to an existing preset point press CALL and the appropriate
number. E.g., to point the camera to Preset Position #2 press CALL and 2.
Set Scanning
Auto Scanning – The camera performs a level scan back and forth among the left and right
limits at a set speed – is incorporated in the ST-PTZMINI-540W. Left and right limits and scan
speed are set using the PTZ Controller. Auto scan can be done using CALL #125 or pressing
the auto-scan button on the PTZ Controller. The camera will auto scan 360° back and forth.
The auto scan speed is fixed.
Linear Scanning – The camera may also be set to scan back and forth between two fixed
positions established as preset positions. The scanning speed can be set from 1° to 50° per
second. By way of example, and using 50° per second as the scan speed, via the PTZ
v2.0 3/21/11

Controller:
Preset #126 for linear scanning.
Preset #1 to 50 (1 being slow, 50 being fast) as the speed index for total scan speed
time. Note each value refers to °/second (e.g., 1 = speed of 1°/second)
Move the controller’s joystick to the beginning location and adjust the image to be
viewed.
Preset #127 as the preset point for the beginning location.
Move the joystick to the ending location and adjust the image to be viewed.
Preset #128 as the preset point for the ending location.
Call 128 to activate the linear scan.
Tour
Automatic Tour is incorporated in the ST-PTZMINI-540W allowing preset points to be inserted
into a tour list. These preset points with timing pauses can be programmed as a tour route. In
so doing, the ST-PTZMINI-540W can automatically follow a predefined path or route. Up to 8
preset points and timing pauses can be stored in the camera. Two tour routes (#101 and
#102) can be created using 8 preset points each. The camera pauses 6 seconds at each
point. By way of example for Tour Route #101 using 3 preset points:
Preset 101.
For preset point 1 – move joy stick to the first location and Preset point 1.
For preset point 2 – move joy stick to the second location and Preset point 2.
For preset point 3 – move joy stick to the third location and Preset point 3.
Call 101 to activate Tour Route #101.
6. TROUBLESHOOTING
a. No picture after applying power – (i) check all plugs and cables are securely
connected to the proper connectors; (ii) ensure your power supply is providing the
correct voltage and current.
b. The picture has ripples – (i) check to see if the power supply is experiencing AC ripple,
if so a filter may be required; (ii) determine if the monitor is faulty; (iii) determine if
other peripheral equipment is causing ripple and if so make the necessary
adjustments.
c. The picture background continuously changes color – a fluorescent lamp’s magnetic
field may cause color roll, therefore, reduce the number of fluorescent lamps or
increase the distance between the camera and the lamps.
d. The picture appears smeared – (i) the power supply voltage level may be unstable,
therefore, try another power supply; (ii) ensure the cables are correctly connected
and/or the cables are of the correct impedance.
e. Other interference may require a SecurityTronix ground loop isolation filter.
f. Power is on, but the controller does not work – (i) check to make sure the DIP
switches for address and communications baud rate are properly set, (ii) check to
ensure the RS485 connections at the camera and the PTZ Controller have the same
polarity, (iii) check the integrity and continuity of the unshielded twisted pair (UTP)
control cable.
g. Additional troubleshooting assistance can be found on-line at www.securitytronix.com
