The CHM22 crossover insertion cards are designed for use with the CX452 modular card cage (sold separately). These units are components of the Nitek UTPLinks video, data & power twisted pair system. The CHM22 crossover cards are unique unshielded twisted pair (UTP) transmission products designed to operate with TIA/EIA standards-based network cabling. The cards plug into and are powered through the CX452 modular card cage. The CX452 is a 1 RU card cage that holds up to 5 of the crossover insertion cards. Power is supplied from a separate PS115 power supply (sold separately). The crossover system and power supply are typically located in an IDF (telecom) closet. There are three card models available and any of the three can be plugged into the card cage in any combination. Each card is designed to accommodate 4 cameras. The primary function of each of the cards is to provide a means of interfacing copper backbone cables to horizontal cable runs and inserting voltage to the individual camera and/or P/T/Z over the horizontal run. In addition, models of the cards are available that provide RS422 distribution and/or video transceivers (see available cards - under Ordering Information). Using a single standards-compliant 4-pair UTP category 5 or better cable, video, data and power can be sent up to 100 meters to a fixed or P/T/Z camera.

  • Three available plug-in cards provide flexibility - any combination of four Crossover cards can be used in any of the CX452 card cage slots
  • Plug-in cards also provide future system expansion or features modification
