benstead 0 Posted March 14, 2013 I am trying to upgrade two of our cameras from Spectra 3 to Spectra 4. I am unable to control the Spectra 4 cameras in either the old back boxes or the ones that came with the Spectra four. My setup is: Spectra 4 in P Protocol --> Sennetech SCT-1067 Sensormatic RS-422 to Pelco RS-422 Code Translator --> USOTL4 - USB to RS-485/422 Converter --> Intellex DVMS. Any suggestions?

survtech 0 Posted March 14, 2013 Spectra III and Spectra IV are operationally the same. If you swap out a Pectra III with a Spectra IV, it should function the same. If it doesn't, check the dip switch settings. Share this post Link to post Share on other sites
treborsz 0 Posted March 18, 2013 You can control Pelco Spectra camera directly from the Intellex using Pelco P or Pelco D protocol via User-Defined Handler. See: viewtopic.php?f=6&t=25430 Share this post Link to post Share on other sites
