Welcome
Thank you for purchasing Pelco’s Pressurized Spectra III
modules with an ST-type connector. Your new system provides ultimate protection of the camera optics and
electronics from moisture, corrosive gases, and airborne contaminants.
This manual is designed to be a reference tool for the installation of your system. For best results and ease of
installation, the dome system should be assembled, pressurized, and tested before installation. A Pressurized
Spectra III cable harness (supplied with the back box) is required to test and monitor the pressurized dome.
