Mounting the radar

The CIR can be mounted on a dedicated post or various other structures (e.g. walls, roofs, gantries, machinery) by use of brackets. For correct operation of the radar, Navtech Radar recommend that any bracket should not move more than half degree in any direction whilst carrying the 6kg load of the radar under the required operating conditions (customer site specific). Ensure that the radar line of sight is not obscured by any existing infrastructure.

To allow the radar to be installed in the optimum position relative to the object to be monitored, the CIR sensor should be fitted to a mounting plate which allows the tilt to be adjusted. The CIR sensor is fitted to the mounting plate using 4x M8 bolts in a 4” PCD pattern (standard CCTV mounting). 

The mounting plate provides a simple method to fine tune the incline of the radar. For each of the mounting holes, the bolt is fed from underneath and locked onto the mounting plate with a nut. Two more nuts are used below the radar base plate and another is used above so that the sensor can be positioned anywhere up or down the bolt thread, as necessary. An extra nut should then be added once the radar is levelled to lock off the position.

Adjusting a radar on its bracket

If the tilt of the radar needs to adjusted in order to achieve optimum scanning, the bolts can be adjusting on the bracket in order to reach the desired level. The best way of understanding whether or not your sensor needs its alignment justified is by using radar targets to establish whether or not the object or area that you wish to detect or monitor is in the radar's line of site. For more detail on how to achieve the best alignment, see Radar View (LINK).

Note: The maximum angle the radar can be tilted on M10 bolts is 7 degrees, relative to the bracket.

Connecting the radar

Each radar sensor requires a power and a network connection. The power and network connections run from the sensor to a local junction box (e.g. at the base of the post) where the power supply is situated. Remember to ensure that the maximum cable lengths remain within the capability of the selected cabling and infrastructure. Please see Appendix A for the Power pin-out and plug wiring details.

To connect power and network

  1. Remove the protective cap from the Ethernet connector and attach the RJ45 plug. Ensure that the weatherproof shroud on the Ethernet connector is secure.Image Removed
  2. Attach the 24V DC plug to the connector (by pushing it fully on and turning clockwise to lock).
  3. Attach a suitable earth cable to the earthing point (requires an M5 bolt).
  4. Ensure that the power and Ethernet cables are securely connected into a suitable junction box that has a suitable 24V DC power supply installed.
    Note: The radar typically draws a continuous 800m A, but when the internal heater is active, this rises to approximately 2.2A. Ensure that the Power supply cabling is correctly terminated - see Appendix A.
  5. Ensure that the junction box has an Ethernet cable/fibre optic running to the infrastructure network switch.
  6. When power is applied, ensure that the radar begins rotating - you can easily hear this, although it takes approximately 10 seconds for the radar to start rotating – in cold conditions this could be longer.

The Vertex interface

The CIR sensor has a built in web interface (known as Vertex) which provides default user level access to the radar. Vertex allows you to view various operational data (e.g. IP address, serial number, System Uptime and Radar health, etc.) as soon as it opens, however, to make any changes you will need to Login.

When first connecting, ensure there is nothing else on the network that is using the same IP address. If necessary, connect a computer directly to the Ethernet port of the radar unit and access Vertex directly in order to change the IP address.
