STEP 1. Connect the BNC and
power leads from the camera
to the matching connectors on
a video/power siamese cable
(Note: these may need to be
purchased separately if your
camera was not included as part
of a bundle package).
CONNECTING THE CAMERA
Before you can operate the camera, you must connect it to a system which can
support PTZ operations. There are three sets of connectors - power, video and
the bare control wires. This latter connection is covered on the next page. We
recommend connecting the camera (at least temporarily) to the DVR to test your
settings and connections before mounting it in its final location.

POWER AND VIDEO CONNECTION
IMPORTANT! When connecting the power and video cable between
the camera and the DVR, the “male” power end (red plug) connects to the
matching power lead on the camera.
PTZ CONTROL CONNECTION
In addition to connecting the power and video leads to the camera, you must also
connect the two control wire leads to the RS485 ports in the alarm block on the
back of the DVR. These blocks can vary in layout as shown below, but the ports
used by your DVR are generally labelled “RS485”, “RS422”, “PTZ” or “P/Z”.
As seen in the picture on the upper right, the wire leads
from the camera are two different colors and are labeled.
They are also pre-installed into a block which plugs into a
matching receptacle on the extension cable. The control
wire leads at the other end of the extension cable must
be inserted into the ports on the back of the DVR. In the
case of the RS485 ports being marked as positive (+) and
negative (-), the wire designated RS485A (red tip) is the
positive lead while the wire marked RS485B (black tip) is
to go into the negative port. Your camera comes with a
connector PTZ blocks either have small screws above
each port to secure the wire or require a lock above the
port to be depressed with an object like a small screw
driver in order to fully insert the wire. In the latter, when the
lock is released, an internal clamp will keep the wire firmly
secured in the port. If the wire can easily be removed from
the port, then it isn’t secure and you can experience control
difficulties until it is properly attached. Space permitting,
multiple PTZ cameras may be connected to the same ports.

Some examples of PTZ blocks. One using screws (left) and two using spring-loaded locks.
They will each require a different address
which is set up using the DIP switches
as covered in the previous section.
To connect your camera to the DVR
over a distance, you will need to use
both a video/power cable and a pair of
24-gauge wires to connect to the alarm
block. If your camera came as part of a
package, these wires may be included
separately or as part of the video and
power cable.
330 or lower, a Joule rating of at least 400 and a response time of 10 nanoseconds
or less.
There are five bare wires labelled “Alarm” and these are used to connect an external
alarm to the PTZ camera. Use of an alarm will be covered later in this manual.
These wires may be ignored if an alarm will not be used.
Once you have made your connections, you will need to make settings on the DVR
in order to control it. You will need to consult your DVR’s manual for this procedure,
but a sample screen (from a Q-See QT-series DVR) is shown immediately above.

STEP 2. Connect the power lead on
the other end of the video/power
cable to a power adapter or power
distribution panel. Make certain
that the power supply is rated for
24 volts and 3 amps.
STEP 3. Connect the BNC connector
on that same end of the cable to
a Video In port on the back of the
DVR.
You can now plug the camera’s power
adapter into a surge protector and turn it on.
To protect your investment, we STRONGLY
recommended using a surge protector that
is UL-1449 rated, for a clamping voltage of
