Modular Power over the UTP CCTV system with built in power supply

Model Number: CX254

  • Modular Crossover Card Cage with built in power supply
  • Component of the UTPLinks™ System

Modular crossover interface card cage with integrated power supply for the UTPLinks video, data & power over twisted pair transmission system.

The CX254 is a 1 RU card cage designed to hold up to five Nitek modular crossover cards for the UTPLinks system, mounted horizontally. The card cage combined with plug-in crossover cards comprises a video crossover and power insertion unit for the UTPLinks system and depending upon the type of cards used, can also include RS422 distribution and/or video transceiver capability. Three models of four-channel crossover cards are available. The cards can be used in any combination, allowing the rack system to be customized to the specific application. (Modular cards are sold separately).

The CX254, configured with plug-in cards, is designed to work with TIA/EIA standards-based structured cabling networks. The crossover card cage provides five (5) RJ45 jacks at the rear of the unit for easy interfacing with either a copper backbone cable or Nitek video receiver equipment. The integrated 24 VAC power supplies power for of each cards.

U.S. Patent No. 7,193,149

Wire and Cable Recommendations

On horizontal runs with fixed cameras (applications up to 8 watts/ port) category 5 or better; 22 AWG or 24 AWG. For P/T/Z camera (applications >8 watts/port) category 5 or better; 22 AWG is recommended. In the case of backbone cable 24 AWG category 3 or better is recommended. Multi-pair cable with an overall shield is acceptable. While signals may be routed through 66 blocks or 110 blocks, any bridge-taps, also called T-taps and any resistive, capacitive or inductive devices MUST BE removed from the pair.
