The New Remote RF Monitoring and Alarm System

Intelligent Control and Display (ICAD)Intelect’s new patent-pending Intelligent Control and Display (ICAD) is an alarm and monitoring system that provides real-time quantitative remote monitoring for all active and passive elements of UHF, SMR and public safety communications systems.

The ICAD system monitors both the uplink and downlink performance of conventional and trunk radio communication systems on a channelized basis, collecting information at a central location so authorized users can access it via a web browser.

ICAD System Overview

This incredible suite of software and devices communicates with multi-band sensors distributed throughout the network to understand the status and health of your UHF or public safety system. See how you can maintain your network’s peak performance from your desk using ICAD:

  • Uniquely monitor, measure, report, and control RF signals, alarms, ambient temperature readings, voltages, current, I/O’s and other key parameters
    • The system evaluates performance against a standard and issues alarms when required
  • Control the operational frequency in the sensors from a remote server
  • Remotely manage and troubleshoot your network
  • Configure your network to self-heal based upon specific parameters
  • Manage both uplink and downlink communications on a channelized basis
  • Support maintenance and installation activities
  • View an audit log of all configuration changes made by your users

ICAD System Components

The following products are integrated into your ICAD System: each device is remotely configurable,

Remote Sensors

Remote sensors are situated through the network at locations where it monitors and reports the status of that node. The sensors receive their instructions and respond over the network through a radio link.

Gain Controllers

The Gain controller is available in two models: the UHF unit can control the RF gain on four independent circuits, while the 800 MHz model can control the gain of two independent circuits using  a RS-232 interface with a remote sensor.  The uplink paths in both models use a low noise amplifier preceding the attenuator to improve the noise figure.  In addition to providing control over the gain, the microcontroller can report the status of both internal and external alarms. In the event of a power failure, the startup conditions will be restored from a EEPROM.

Features and Benefits
  • Up to four Independent Gain Paths
  • Gain controlled in 0.5 dB Steps
  • High Dynamic RangeGain Control via RS-232
  • Operates from 400 to 900 MHz
  • Provides Alarm Status
  • EPROM based – restores normal

RF Controllers

The RF Controller is a bi-directional device whose primary function is to translate Ethernet messages from the ICAD Server to bi-directional RF signals that communicate with the remote sensors.  The RF Controller is band-specific and is available to operate in either the UHF or the SMR band.

The RF Controller is available in two output configurations:

  • Single connector for both uplink and downlink (typically off air interfaces)
  • Individual uplink and downlink connectors (typically for fiber optic interfaces)

The RF Controller is available as a rack mounted unit or as a wall mounted unit.

Features and Benefits
  • Tri-band – 490 MHz, 700 MHz and 800 MHz
  • Remotely controlled
  • Accurate receiver – synthesized
  • Downlink transmitter
  • Stable frequency operation
  • Narrow bandwidth
  • Unique address
