iii
Precautions on Installation
Please ensure you have confirmed the following prior to installing the Mini Speed PTZ Camera:
• Follow all local safety regulations
• If connecting optional accessories, please make sure they are compatible and in complete
working order. For a full list of optional accessories, visit www.lorexcctv.com
• Check if the installation location is strong enough to support the camera and bracket without
immediate danger of falling.
Cable Standards
Coaxial Cable
Select the proper cable length for your installation distance. The maximum recommended lengths
are as follows:
• RG59/U: 750ft (230 meters)
• RG61/U: 1000ft (305 meters)
• RG11/U: 1500ft (457 meters)
RS485 Cable
Please comply with RS485 wiring standards when connecting RS485 cables. Improper
connections may result in transmission errors which may cause speed dome cameras to react
incorrectly.
If you use thin or low anti-interference RS485 cable when connecting the camera, the maximum
transmission distance may be shortened.
Standard rule for RS485 transmission distance:
When using 20AWG(Belden 8760) Shielded Twisted Pair Cable, different control Baud Rates will
have different transmission distance performance:
2400 1200 meters / 3937 feet
4800 1000 meters / 3281 feet
9600 800 meters / 2625 feet
Baud Rate Maximum Transmission Distance

iv
Setting Camera Codes and Protocols
Prior to installation, setup ID address and communication protocol of your camera. Make sure the
camera is powered OFF when resetting IDs or protocols after installation. When you have set the
new IDs or protocols, power on the camera to implement the changes.
Camera Self-Test
Prior to mounting the camera, power on the camera to activate a self-test. To activate the
camera’s self-test, power-on the camera—the camera will automatically tilt up/down scanning and
then pan hoizontal scanning for approximately 20~30 seconds. The camera will stop at Preset
Point 1. The Mini Speed Dome Camera is now in normal mode.

Installing the Camera
Installing the Camera
There are two methods of installing the Mini Speed Dome Camera*: cable pass-through, or visible
cable.
Prior to installing the camera, make sure of the following:
• You have powered-on the camera to run the automatic Self-Test (see Camera Self-Test
page iv)
• You have connected the camera to a TV, DVR, keyboard controller, or observation system(not
included) to check the video signal and RS-485 connection to ensure the camera, TV, DVR,
keyboard controller, or observation system are functioning properly
Cable Pass-Through
The cable pass-through method involves drilling a hole in the mounting surface large enough for
the BNC/RS-485/Power cable to pass-through. This method conceals the cable from view and
prevents tampering.
To install the camera:
1. Drill an opening in your mounting surface large enough for the cables to pass through—
approximetaly 2 cm/0.79 in in diameter.
2. With the pass-through hole drilled in the mounting surface, feed the BNC/RS485/Power
cable through the hole.
3. Feed the BNC/RS485/Power cable through the large hole of the included mounting plate.
4. Fasten the mounting plate to to the surface using the included mounting screws.
5. Connect the serial port of the BNC/RS485/Power cable firmly to the port on the base of the
camera.
6. Place the camera on the mounting plate, making sure to line up the arrow on the base of the
camera with the arrow on the plate. The camera should be flush against the mounting plate.
7. Turn the base of the camera clockwise until it clicks into place.

Installing the Camera
Visible Cable
The visible cable method leaves the cable extending from the camera to the DVR, monitor, or
observation system. This method is suggested if drilling a pass-through hole is not a viable option
for installation.
To install the camera:
1. Fasten the mounting plate to the surface using the included mounting screws.
2. Secure the serial port of the BNC/RS485/Power cable firmly to the port on the base of the
camera.
3. Tuck the cable into either of the slots in the base of the camera as best suits your wiring or
mounting environment.
4. Place the camera on the mounting plate, making sure to line up the arrow on the base of the
camera with the arrow on the plate. The camera should be flush against the mounting plate.
5. Turn the base of the camera clockwise until it clicks into place.

Figure 2.2 Tuck the cable into slot (B)
Figure 2.3 Mount the camera

7
Installing the Camera
For both installation methods, double-check that the Mini Speed Dome Camera is firmly in place
to prevent any risk of it falling down.
Electrical Test
Once the camera is mounted, connect the cables. If the camera is connected correctly and
receiving sufficient power, it will automatically execute the Self-Test: the camera will tilt up/down,
pan horizontally, and stop at Preset Point 1. The camera is now ready for normal operation.
RS-485 Wiring
There are two methods for wiring an RS-485 connection: Serial and Aster. Use either of these
recommended wiring methods to prevent malfunction of RS-485 control.
RS-485 Serial Connection
This method connects speed dome cameras in a sequential manner where the first camera
connects to the second, the second to the third, and so on. A terminal resistance is connected to
the last camera to form a closed loop.
Figure 3.0 Serial connection method
When using a serial connection, you can connect a maximum of 32 PTZ dome cameras; if you
need to connect more than 32 cameras, you should use the aster connection method.

8
Installing the Camera
RS-485 Aster Connection
This is the most common method in practical installation of PTZ cameras. In an Aster Connection,
you need to use a RS-485 distributor to reduce interferance and stabilize the connections.
Figure 3.1 Aster connection method
Note: Without a RS-485 distributor, you risk causing a malfunction of the control signal or
basic camera opeations

Connecting the Camera
Connecting the Camera
The Mini Speed Dome Camera works on a BNC channel of most DVRs and observation systems.
Please refer to your observation system’s instruction manual for details on available channels for
PTZ functionality.
To connect the camera:
1. With the camera securely mounted, connect the three terminating ends of the BNC/RS-485/
Power cable to the 65 ft. BNC/RS-485/Power Extension Cable.
2. Connect the three terminating ends of the 65 ft. BNC/RS-485/Power Extension Cable to the
following:
• BNC: Connect to a BNC port on the DVR or observation system
• RS485: Connect the terminating wires to the RS-485 port on the DVR, keyboard controller,
or observation system (white=positive +, black=negative —)
Note: DVR, keyboard controller, or observation system must support a Pelco-D/P protocol.
• Power: Connect to the included DC power adaptor.
3. Turn on the DVR or observation system.
• Connect to Power
Adaptor
• Connect to BNC input
• Connect to RS-485 ports

Changing the Camera Address Settings
Changing the Camera Address Settings
The DIP switches inside the camera (1~10) can be changed to set a unique address for the
camera (between 1~255). By default, the camera is set to channel 1.
• If using a single camera, the address does not need to be changed. Refer to the Hardware
Manual for the Observation System for camera channel placement and configuration.
• If using multiple cameras, each camera must be set to a unique address using the internal
DIP switches. See Figure 5.0
Note: Make sure the camera is powered off before changing the DIP switches.
To access the DIP switches:
1. Open the soft plastic cover on the back of the camera. A 10-pin DIP switch, SW9/10 is
visible.
