CHM12A Nitek Crossover & 12VDC Power Insertion Module w/ 4 Video Transceivers

The CHM12A and CXM12A Crossover Insertion Cards designed for use with the CX452 Modular Card Cage (purchase separately). These are components of the NITEK UTPLinks Video, Data & Power Twisted Pair System.

The CHM12A and CXM12A Crossover cards are unique unshielded twisted pair (UTP) transmission products designed to operate with TIA/EIA standards-based network cabling. The CHM12A and CXM12A provide 12VDC for DC powered cameras. When used with other UTPLinks cards 12VDC cameras can be mixed with 24VAC cameras in a system. The CHM12A has built in receiver units.

The CXM12A is designed for midspan power applications. The cards plugs 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 PS105 or PS110 Power Supply (purchase separately). The Crossover system and Power Supply are typically located in an IDF (telecom) closet.

Each card is designed to accommodate 4 cameras. The primary function of the cards is to provide a means of interfacing copper backbone cables to horizontal cable runs and inserting voltage to the individual camera over the horizontal run. Using a single standards compliant 4-pair UTP Cat 5 or better cable, video, and power can be sent up to 100 meters to a fixed camera.
