Set up the plate reader in police cars

The plate reader, often called ALPR, puts a plate camera in every police car. Officers on duty turn it on with /alpr, and it reads the plates and speeds of the cars in front and behind. Each plate is checked against the CAD the same way your fixed plate cameras check them, so a stolen car or a wanted owner shows up while it's still in front of the officer.

This article is for whoever runs your Cameras setup. For how officers use it, see Use the plate reader in police cars.

Before you start#

• The Cameras and CAD modules need to be installed.
• Your game server needs the LonexOne FiveM resource, version 0.4.0 or newer. Turning on by itself, locking, running plates, calls, lanes and volume need 0.5.0 or newer, and the ONE 3000 remote that /alpr opens needs 0.5.1. Update it from Keymaster if your server has an older copy. See Install the LonexOne FiveM resource.
• To change the settings, you need the Place cameras in game, edit them and choose who they alert permission.

Switch it on or off#

The plate reader starts switched on as soon as you install Cameras.

1. Open your control panel and click Cameras in the sidebar.
2. In the Settings box, tick or untick Plate reader in police cars.
3. Click Save settings.

Switching it off stops plates being checked straight away. Officers who already had the reader on still see plates and speeds until they turn it off, but nothing is flagged. Once the game catches up with the change, which takes a few moments, nobody can turn it on.

You don't need any fixed cameras placed to use the plate reader. It works on its own.

Turn it on in emergency vehicles#

With Turn it on in emergency vehicles ticked, the reader comes on by itself when a police officer on duty gets into the driver's or front passenger seat of an emergency vehicle, and goes off when they get out. Officers can still turn it off with /alpr, and it stays off until they leave that car. It starts ticked.

Plate history#

The plate history keeps where the plate readers saw each player's car: the plate, model, speed, postal, street, time and which unit read it. Use it to answer "where has this car been?" in an investigation.

1. On the Cameras page, click Plate history.
2. Type a plate, or part of one, and click Search.

Set how long it's kept in Keep plate history for, in the Settings box, from 0 to 90 days. It starts at 7. Older entries are deleted every night. Set it to 0 to keep none; anything already kept is deleted that night.

Only cars driven by players are kept, never AI traffic. A plate goes into the history each time the reader checks it, which is once every two minutes per officer, so it's a trail of sightings rather than every second.

Anyone who can see the Cameras page can search the plate history.

Choose what makes a plate a hit#

The plate reader uses the same checks as your plate cameras. In the Settings box, under A plate is a hit when, tick what should count:

Click Save settings when you're done. The same ticks apply to your fixed plate cameras, so you can't set them differently for the reader.

The Speeds in setting also applies to the reader: officers see speeds in mph or km/h to match.

Where hits go#

When the reader finds a hit:

• The officer hears a beep, gets a message in game with the plate and the reasons, and that side of the reader turns red.
• A broadcast goes to the officer's department in the CAD, from Plate reader, with the callsign and the hit. Dispatchers see it too.
• The hit is added to the alerts list on the Cameras page, shown as Plate reader with the callsign and department that read it. The callsign stays on the alert after the officer signs off.

Fixed cameras alert the departments you pick for each camera. The plate reader always alerts the department of the officer who read the plate, so there's nothing to set up for it. For fixed cameras, see Choose who camera alerts go to.

Stop the same plate alerting again and again#

An officer following a stolen car would otherwise get a hit every few seconds. Two things hold repeats back:

• The game only checks each plate with LonexOne once every two minutes per officer.
• Same plate on the same camera alerts again after, in the Settings box, also covers the plate reader. A plate read by the same unit isn't logged or broadcast again until that many minutes have passed. It's 5 minutes to start with. Set it to 0 to log every check.

Rename the command#

/alpr is the starting name. To change it, open Status & servers, click the Game resource tab and change it under Commands.

Something not working?#

Officers see "The plate reader isn't switched on for this server. It needs the Cameras module on LonexOne." Install the Cameras module and tick Plate reader in police cars in the Settings box on the Cameras page. If you've just changed it, give the game a few moments to catch up.

Officers see "The plate reader is for police on duty". They need to be on duty with a police department. Fire, EMS and dispatch units can't use it.

/alpr does nothing at all. Your server is running an older LonexOne resource. Update to version 0.4.0 or newer and restart it.

The plate history is empty. Check Keep plate history for isn't 0. Only player-driven cars are kept, and only from resource version 0.5.0.

Every car is a hit. Plate not on file is on and players drive cars with plates that aren't in the CAD. Untick it, or make sure players register their vehicles.

Hits show in game but not in the alerts list. The same plate was read by the same unit within the repeat time, so it wasn't logged again. Lower Same plate on the same camera alerts again after if you want more of them logged.
