Relevant Models / Series: LZC7091, LZC71

 

 

Q: Why is the image unclear when the camera is pointed at certain angles?

A: This PTZ camera is designed to tilt up and down within a range of 155°. Tilting less than 10° or greater than 165° away from the camera base may cause the image to become slightly unclear. It is recommended to install the camera as high up as possible.

If the image becomes unclear, use the DVR controls to tilt the camera between 10° and 165°. The camera’s tilt angle appears on the monitor when it moves as shown below.

Q: Can I extend the cable beyond the supplied 100ft extension cable?

A: Yes, the video cable and RS-485 PTZ control cables can be extended up to 350ft (106m) from the camera. However, due to the high power requirements of this camera, the power cable can not be extended further than 100ft (see "Power" section below for more details).

To extend the video cable and RS-485 PTZ control cables beyond 100ft:

  • Video Cable: Use RG59 coaxial extension cables. It is recommended to use video cables with the following specification: RG59U 95% Braid 20AWG or better. Up to 250ft of additional video cabling may be added to the supplied 100ft cable.
  • RS-485 PTZ Controls: Use a pair of 24-gauge wires. Use the included RS-485 connection terminals to connect RS-485 wires to each other. See images below for details.

  • Power: Because of the high power requirements of this camera, you must connect the power adapter within 100ft of the camera. Depending on the version of the camera, different cables may be included. Earlier versions of the camera included a 100ft extension cable only, which connects directly to the camera using a special 6-pin connector. Newer versions include a 3ft cable that connects directly to the camera, using the 6-pin connector, and a separate 100ft video/power/RS-485 extension cable. See the setup diagrams below for details.
