What is an MDT in FiveM? Police Computer Systems Explained

Instead of alt-tabbing out of the game to check a spreadsheet, personnel use an in-game animated tablet or laptop prop. This keeps players engaged in the world and prevents the immersion breaks associated with external record-keeping.

Centralized Records

An MDT acts as a permanent, server-side memory bank. When a stop occurs, they can look up a character name to see:

• Previous infractions and records.
• Active driver's licenses or permits.
• Known affiliations or notes.

Real-Time Dispatch and GPS Tracking

Modern MDTs integrate directly with FiveM Police Scripts to provide a live map of all active LEO and EMS units, alongside active calls.

Core Features of a High-Quality FiveM MDT

If you are a server owner looking to purchase or configure an MDT, these are the essential features to look for:

1. Citizen Database

The core of any MDT. It queries your framework's database (like ESX or QBCore) to display every registered character. You can attach mugshots, update addresses, and revoke licenses directly from this page.

2. Vehicle Registration System

When a vehicle is purchased by a player, the MDT registers the license plate to that owner. If a car is reported stolen, users can flag the plate in the MDT so that ALPR (Automated License Plate Reader) systems can alert them later.

3. Incident Reports

After a major scenario, LEOs need to document the event. Advanced MDTs allow them to:

• Tag multiple individuals in a single incident.
• Upload photos of evidence (via Discord webhooks or Imgur links).
• Automatically calculate fines and times based on a built-in Penal Code.

4. Warrants and BOLO Systems

If an individual escapes a chase, an officer can issue a BOLO (Be On The Look Out) or an active warrant. The next time that suspect interaction occurs, the MDT flashes a high-priority alert.

Technical Implementation of MDTs

For developers, understanding how MDTs work under the hood is vital. MDTs typically use one of three implementation approaches:

NUI (CEF) Based – Most Common

Most FiveM MDTs are built using FiveM's NUI (Native UI) implementation, which runs a Chromium browser within the game. Developers build the interface using modern web frameworks like React, Vue, or Svelte.

Here is a simplified example of how an MDT is opened via the client:

-- Client-side NUI trigger example
RegisterCommand('mdt', function()
    SetNuiFocus(true, true)
    SendNUIMessage({
        type = 'openMDT',
        officerName = GetPlayerName(PlayerId()),
        badgeNumber = GetPlayerServerId(PlayerId())
    })
end)

And the server-side logic handles the heavy database querying to prevent client manipulation:

-- Server-side database query
RegisterServerEvent('mdt:searchPerson')
AddEventHandler('mdt:searchPerson', function(firstname, lastname)
    local src = source
    MySQL.Async.fetchAll('SELECT * FROM users WHERE firstname = @first AND lastname = @last', {
        ['@first'] = firstname,
        ['@last'] = lastname
    }, function(result)
        TriggerClientEvent('mdt:returnSearch', src, result)
    end)
end)

External Web Applications

Some premium MDT systems (like Sonoran CAD) operate completely outside of the game on a standard web browser. While this requires players to have a second monitor or use alt-tab, it saves significant server performance and allows dispatchers to play without even launching Grand Theft Auto.

Framework Integration (ESX / QBCore / Qbox)

An MDT is useless if it cannot read your player database. Ensure the MDT you choose natively supports your server's framework. It needs to know which SQL tables to query for characters (users vs players). If you are migrating, check out our ESX to QBCore Migration Guide.

Connecting MDTs to Other Scripts

To truly unlock an MDT's potential, it should interconnect with other scripts:

• Dispatch / 911 Scripts: Calls should feed directly into the MDT's board.
• Confinement Scripts: When a report is submitted, pressing "Submit" should physically teleport the target player into the processing area.
• Phone Scripts: Players should be able to view their own records or pay citations via apps built into their FiveM Phone.

Popular FiveM MDT Scripts Compared

With so many options available on the CFX forum and mod marketplaces, choosing the right MDT comes down to your framework, budget, and how much customization you need. Here is a comparison of the most widely used MDT and CAD systems in 2026:
