PTZ Camera Setup & Configuration

  1. In order to gain access to the PTZ dip switches to configure the camera’s setting, you must remove the camera from the housing.  The first step is to remove the dome cover of the camera using the allen wrench that came with the camera as seen below.

  2. Next, remove the screws that hold the actual PTZ camera inplace in the housing using a phillips head screw driver.  Please be careful when removing it, as the camera will still be attached to the base of the housing after you remove the screws.  Using a long phillips screw driver, remove the screws that attach the camera to the housing as seem below.

  3. Carefully remove the camera from the housing.  BE AWARE, the camera will still be attached to the housing with wires that will not be removed.  Once you have the camera outside of the housing, you will see the DIP switches on the top side of the camera as seen below.

    The DIP switches will look like this close up.  Notice that there are 3 difference setting areas: SW1, SW2, SW3.

    PTZ-Camera-Protocol Settings

  4. The SW1 settings are used to configure the ID of your PTZ camera.  Assuming that this is the first PTZ that you want your controller to operate, set this camera’s ID to 001.  Do this by setting switch #1 to the On position and the rest of the switches should be set to Off.  If you are setting up more than one PTZ camera on a single system or controller, each camera must have a unique ID so that the controller knows which one you are wanting to comtrol.
  5. The SW2 settings are used to set the protocol that your camera wil use.  Set the protocal to PELCO by setting switch #1 to On and the rest of the switches to Off.
  6. The SW3 settings are used to set the baud rate that your PTZ camera will use.  Set the baud rate to 9600 by setting all switches to the Off position.

  7. Attach wire to the RS 485 +/- positive and negative terminals of your camera as seen below.  Cat-5 or a standard power wire such as doorbell wire can be used for this.  Doorbell wire is used below.  *Note: Make sure that your wire makes contact with the metal part of the inside of the terminal.  A common mistake is to clamp the plastic part of the wire.

  8. It is best to test out your camera communication before going through the trouble of mounting your camera and running all of your cable.  Once your communication has been tested to your PTZ camera, you should then run your wires and mount the camera
  9. Put the camera back in the housing by following the reverse order of how you took it out.  Mount the camera back into the housing using a long phillips head screw driver.  You may want to use a magnetized screw drive because it is a real pain if you drop the screws into the bottom of the housing.
  10. Next, re-attach the dome cover using the allen wrench screws.

Huaben CCTV Camera  hopes that your installation goes smoothly, but in case it does not, please email or call us for help.

In order to choose the best CCTV Security System and CCTV Cameras you need to understand some of the basic terminology. Below is a glossary of CCTV terms to help you choose your Surveillance system and

This glossary contains a list of general terms and definitions related to surveillance systems, security cameras, and CCTV equipment. If you find any terms on our web site that you do not understand and can not find in this glossary, please email or call us so that we can add it.

Auto Iris 
Security cameras with auto iris, have the ability to compensate for large variations in light levels. This is useful for security cameras that need to adjust for changes from bright sunlight to darkness or night. Auto iris circuitry is normally linked to a motorized drive that opens and shuts the iris on the camera lens. Closing a physical iris is a much better way to protect a camera from being damaged by bright sunlight then simply using electronics to reduce the signal strength.

Alarm Input 
Some DVRs and security cameras have alarm inputs, which can accept input from a sensor device such as a door contact or a passive infra-red motion detection which trigger the camera or DVR to take some action such as to begin recording.

Aperature -The opening of the CCTV lens.  The size of which is controlled by the iris and is measured in F numbers. Generally, the lower the F number, the larger the aperture is and consequently more light can pass through the lens.

Back Light Compensation 
This is a feature of security cameras that automatically adjusts the image to compensate for bright light to give more detail on the darker areas of the image. For example, use is to focus on the detail of a face of a person that has the sunlight shining from behind.

Balun 
A Video Balun enables the transmission of video using unshielded twisted pair wire instead of coaxial cable. The word “balun” comes from combining the terms balanced and unbalanced. The function of a balun is to transform an unbalanced signal into a balanced signal. When video signal is transmitted through coaxial cable, the distance traveled by the signal is limited because the signal is in the form of an unbalanced signal that is susceptible to Radio Frequency Interference or noise. Coax cable incorporates special shielding to minimize noise. Video Baluns transform the video signal into a balanced form in which each wire in the twisted pair transmits an identical signal with opposite polarized magnetic fields. Noise affects each signal equally. When the signals are combined, the noise is cancelled out. By using a designed balun, an unshielded twisted pair wire can transmit video for much longer distances than coax cable and with a lower cable cost.

BNC Connector
BNC is a connector for coaxial cable that is most commonly used for CCTV installations.

POE(Power Over Ethernet)

Power over Ethernet (POE) is a technology that integrates power into a standard LAN infrastructure. It enables power to be provided to the network device, such as an IP phone or a network camera, using the same cable as that used for network connection. It eliminates the need for power outlets at the camera locations and enables easier application of uninterruptible power supplies (UPS) to ensure 24 hours a day, 7 days a week operation.

POE technology is regulated in a standard called IEEE 802.3af and is designed in a way that does not degrade the network data communication performance or decrease the network reach. The power delivered over the LAN infrastructure is automatically activated when a compatible terminal is identified, and blocked to legacy devices that are not compatible. This feature allows users to freely and safely mix legacy and PoE-compatible devices, on their network.

The standard provides power up to 15.4W on the switch or midspan side,which translates to a maximum power consumption of 12.9W on the device/camera side -making it suitable for indoor cameras. Outdoor cameras as well as PTZ and dome cameras have a power consumption that normally exceeds this, making POE functionality less suitable. Some manufacturers also offer non-standard proprietary products providing suitable power for these applications as well, but it should be noted that since these are non-standard products, no interoperability between different brands is possible. The 802.3af standard also provides support for so-called power classification, which allows for a negotiation of power consumption between the PoE unit and the devices. This means an intelligent switch can reserve sufficient, and not superfluous, power for the device (camera) – with the possible result that the switch could enable more POEoutputs.

Using Power over Ethernet

POE works across standard network cabling (i.e. cat-5) to supply power directly from the data ports to which networked devices are connected. Today, most manufacturers offer network switches with built-in PoE support. If an existing network /switch structure is in place, customers can benefit from the same functionality by adding a so-called Midspan to the switch, which will add power to the network cable. All network cameras without built-in POE can be integrated in a PoE system using an Active Splitter.
