Introduction

This page deals with the assembly of the demonstration kit.

Contents

Position the Equipment

The supplied camera has a 3 metre fixed lead while the radar sensor uses two cables that are 5 metres each in length. Both pieces of equipment need to link back to the supply unit, so consider this when deciding on their relative positions. You will also need a source of mains power (110 to 240VAC 50/60Hz) to the supply unit. The camera, radar sensor and supply unit (plus all of their connections) are environmentally sealed to IP67 to allow operation in most outdoor conditions.

Mounting the Camera and Radar Sensor

The radar sensor and the camera are both supplied with 4” PCD adapters fitted to their bases. The adapters have a central hole with a 5/8” thread so they can mate with the standard mounting bolt fitted to certain models of surveyor tripods. We suggest that you acquire two surveyor tripods, each with an elevation adjustment and also a quick-connect spring-loaded mounting bolt. This will make the job of fitting, particularly the camera, much easier. A third tripod with 5/8” thread mount may also be needed to hold the supplied radar target above ground level.

To Mount the Radar Sensor and Camera

We strongly recommend that you get assistance to mount the radar sensor and camera onto the tripods. The camera in particular is heavy and has a top-heavy construction.

  1. Place the tripods in their intended positions.

  2. With the assistance of a colleague, lift the radar sensor/camera onto the tripod so that the hole in the middle of the adapter plate (on the underside of the radar sensor/camera) locates with the 5/8” threaded bolt of the tripod.

  3. Tighten the threaded bolt until it is tight. Some tripods use a twist knob to tighten the bolt; on other versions you may need to turn the body of the radar sensor/camera to tighten it onto the bolt. 

When removing the radar sensor from the flight case, and when carrying it, lift it only by the metal blue base. NEVER lift it by the white plastic dome.

To Align the Radar Sensor and Camera

Position the two tripods 3 metres apart with the camera to the right of the radar, relative to where you will be positioned for the demonstration.
Set the height of the radar sensor and camera to approximately 1.8m above either the ground level, or the level on which the people you want to detect will be walking.
For full details about alignment, see Aligning the Radar and Camera.

Connecting the Equipment

You can connect the cables in any order, however, it is good practice to connect and switch on the mains supply as your final step.

As well as the supplied cables, you will also require a standard network cable that is of sufficient length to reach from the radar/camera location to the place where your controlling computer will be placed. An environmental protection shell is supplied within the kit to convert one end of your standard cable into an IP rated plug for outdoor use.

To Connect the Equipment

  1. Position the supply unit so that it is close to (or between) the radar sensor and the camera.

  2. Remove the protective caps from the data connector on the radar sensor and the caps from all of the connectors on the supply unit EXCEPT the one marked Spare Ethernet (unless you intend to use it for a second camera connection). 

  3. Locate the supplied Radar data lead. Connect the slightly larger of the two plugs on the cable (it has an RJ45 network connector within it that protrudes much less than that of the other plug) to the socket marked Radar Ethernet on the supply unit.

  4. Locate the supplied Radar power lead. Connect the green plug to the socket
    marked Radar Power on the supply unit.

     

  5. Feed the cable from the camera to the supply unit and connect it to the socket labelled 'Camera Power and Ethernet'.

  6. Fit the supplied IP67 protective shell to the connector at one end of your standard Ethernet cable (the end that will go to the supply unit). Instructions on how to fit the protective shell are printed on the bag in which it is supplied, or you can view an animation on the manufacturer’s website: www.rjfield.com  - Within the site, choose the ‘RJ Field’ link, then click the ‘RJF’ option and then click the ‘Show animation’ link.

  7. Once the shell is fitted, connect it to the connector labelled 'Camera Power and Ethernet' on the supply unit. Connect the other end to the network port on your computer.

  8. Locate the Supply unit power lead. Insert the black and yellow plug into the socket labelled 110-240VAC Supply on the supply unit. Connect the other end to a environmentally protected mains supply socket. The cable is supplied as standard with a UK 13A mains plug. You may need to replace this plug for your own national standard.
