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.
