6.1 CONNECTING A PTZ CAMERA

The RS485 connector is used to connect and control PTZ cameras. It uses a single-direction protocol meaning that it can send commands out to the camera(s) but not receive any data back from the unit.

The DVR is set by default for RS485 to be disabled for each channel. Therefore, PTZ settings must be enabled before PTZ cameras can be utilized. This system supports 26 of the most common protocols including Pelco-D and Pelco-P.

When connecting a PTZ camera, the following should be taken into account:

• Ensure that the camera has the same grounding with the DVR otherwise you may not be

able to control the PTZ. Shielded twisted wire is recommended with the shielded layer being

used to connect to the ground. Improper grounding may result in chip damage.

• For excessively long wire runs, or if multiple PTZ cameras are connected to the DVR, 120Ω

should be parallel connected between the A and B lines on the far end to reduce reflection

6.2 PTZ CONTROL AND SETUP

The following instructions are based on the Pelco-D protocol. You will need to have the manual for your PTZ camera at hand to ensure the proper settings within the DVR.

SETUP

For ease of set-up, the PTZ camera’s video feed should be displayed on the screen.

STEP 1. Open the Pan/Tilt/Zoom Menu from the Settings menu. You cannot use the Shortcut Menu to access the PTZ controls until after you have configured a channel to use PTZ.

and maintain the signal quality

• The 485 port of this DVR cannot parallel connect with the 485 port of another device

• The voltage between the A and B lines of the camera should be less than 5V.

STEP 2. Be certain that the channel

listed at the top is the one which the PTZ camera will be connected to. Enter data into the other fields according to the data provided in your PTZ camera’s manual, including protocol, data bits, stop bits and parity.

STEP 3. Click the save button once you have entered the settings. If you are operating an identical PTZ camera on another channel, you may use the Copy and Paste buttons to apply those settings to the channel that camera is connected to.

STEP 4. Once you have saved your settings and exited the menu, you can right-click the mouse to bring up the Shortcut Menu allowing you to select the Pan/Tilt/Zoom controls.
