How to connect PTZ Camera
How to connect PTZ Camera (Pan Tilt Zoom) to your DVR system PTZ
cameras are secure and reliable, it is with function to change their
positions according to the PTZ camera type, and you can Pan Tilt and
Zoom the camera in a remote position.
Before the controller keyboard
and PTZ cameras can communicate, they have to run on the same protocol
and interface for the technology to work the DVR systems. You'd better
make sure they are compatible when purchasing PTZ camera equipment. The
most common way to interface and control a PTZ camera is the Pelco D
protocol with RS485 interface.
PTZ Camera Connection Diagram
Between
devices: For the DVR system to communicate with the camera, through an
interface conduit to the PTZ camera, command protocol has to be
transmitted from the DVR or controller keyboard. RS485 or RS232 are the
common interfaces for PTZ, by running a single pair or twisted pair
cable from the DVR to the PTZ camera, then they are does. An RS232 is
usually used in a very short distance. RS485 interface is used by most
PTZ cameras and can work over very long distances. Almost every
standalone DVR have RS485 interface. PC based DVR features an RS232
interface with a converter to RS485.
No matter DVR is a PC based
or Standalone DVR needs to send out command signals to PTZ cameras to
control pan, tilt or zoom. Meanwhile, the PTZ camera must know these
commands and then should follow the instructions. In order to let the
two devices to understand each other, they need to use the same
language, which is PROTOCOL. Pelco D is the most common protocol for PTZ
cameras. Please make sure they support the same protocols before you
purchase security DVR system and PTZ security cameras.
Multi PTZ
cameras. If you want to install over one PTZ camera on the same CCTV
system,1 you need to tell DVR how to make a difference between the
cameras. In this way, you could control specific cameras and don't
affect the others. PTZ cameras features dip switches that allow you to
select different camera addresses for example: camera 1 ID=1, camera 2
ID=2, Camera 3 ID= 3 etc. Follow the camera manual instructions to setup
camera ID.
Connecting a PTZ camera to a DVR To connect a PTZ camera to a DVR, you need three types of cable (See diagram)
1.
Most power cable refers to as 18/2 to send 12V or 24V power to the
camera (The Siamese cable has both Power and Coax in one). Connect from
the power supply to the DC or AC connector on the security camera.
2.
RG59 Coax. The Video signal is connected from the BNC connector on the
camera to the BNC camera in on the security DVR, and it will send the
video signal from the camera to the DVR.
3. Pair / Twisted Pair
cable. Each copper pair cable that will send the PTZ command from the
DVR to the PTZ camera. This cable connects from the RX+ RX- on the PTZ
camera to the RS485 connector on the Security DVR or PC Based DVR.
DVR Setup On
the Security DVR, no matter it is a standalone or PC based, you need to
set the devices protocol, baud rate, and camera ID on the DVR according
to the specs provided to you by the camera manufacture. Certainly, all
PTZ camera IDs on the same system have to be unique. Be sure to map the
camera inputs with the corresponding IDs.
Please be careful of the
writing scheme for RS485 interface when you are installing multiple PTZ
cameras on one DVR system. Two ways are as follows:
PTZ Daisy Chain
1.
All the Coax cable RG59 and Power run from each camera to the Security
DVR or PC based. All twisted pairs would run from each camera and
combine all the RX+ from the entire camera and the RX- from all the
cameras and connect to the same interface on the RS485 on the DVR
(Please
be sure that the polarity for the twisted pair is right). The longest
run cable would have to be terminated with a resistor
2. Daisy
chain: In order to let you get to the furthest camera, you should run
the twisted pair from the RS485 interface on the security DVR to the
closest security camera, then, from this camera to the next PTZ camera,
and to the next camera
