Note: this is assuming you have a pl8rdr computer already set up.
Your Survision camera should come with a cable. This is only used for providing power to the camera; the camera connects to the pl8rdr computer wirelessly. Power on both the pl8rdr computer and the Survision camera.
Choose a plate on a vehicle to be your reference. Park your enforcement vehicle behind it and to the side, as if you were driving past a street-parked car. The camera on your vehicle should be 5 meters away from the reference plate, and angled less than 30 degrees off the front of the plate.
(This diagram shows a vertical angle, but the same applies horizontally.)
The pl8rdr will broadcast a WiFi network: pl8rdr.opscom (your contact at OPS-COM will provide you with a password if needed). Connect to this on a device of your choice. The screenshots in this demonstration are from a phone, but any laptop or mobile device should work.
In your browser, go to the IP address of the camera; your contact at OPS-COM will have provided you with the address.
Click on "Configuration assistant".
Proceed through the first 3 screens by clicking "Next" each time. These settings will have already been configured for you.
On the 4th screen, you will be prompted to set the camera angle. Adjust the camera on your vehicle until the plate you have chosen as your reference point is centered in the green box. The lines of text above the camera feed should all turn green when it is set correctly. When you are done, click "Next".
On the 5th screen, leave all the fields blank and click "Finish". The next screen may display an error message saying no address is configured. You can safely ignore this; the address is configured on the pl8rdr.
Your camera should now be set up at the correct angle. You can go through this quick setup process every time you need to reposition the camera on your vehicle.
