Overview

seeker_dsr2x is a police radar modelled on the STALKER DUAL DSR 2X. Two antennas run at the same time, each with its own windows, so a car closing from the front and a car overtaking from behind are both tracked without switching antennas. For anything not covered here, the real DSR 2X Operator's Manual applies.

#Requirements

• ox_lib, started before the radar.
• The radar only appears for a player driving or riding in front in an emergency vehicle (Config.allowedVehicleClasses).

Press F5 to open the remote. See Remote and operator menu.

#The windows

 XMIT  └────────────┘↓  LOCK       └────────────┘↓   │   PATROL   │   <- shared
 SAME  ┌────────────┐↑  FAST       ┌────────────┐↑   └────────────┘

 XMIT  └────────────┘↓  REAR FRONT └────────────┘↓

• Top row: the FRONT antenna. Bottom row: the REAR antenna. Right: PATROL SPEED, shared by both rows.
• There's no ANT button: neither antenna is ever "the active one". Zones, hold and locks are set per row.

A car pacing you lights neither arrow.

#Audio

• Doppler tracks the TARGET window's speed only; your own speed doesn't come into it. Only one row makes noise at a time (Config.dopplerSource: front, rear or strongest). Pitch stops climbing at 100 mph.
• Squelch on (normal): you hear it only while a car is tracked. Off: it runs all the time, like an open beam.
• Voice callouts: on a lock the unit speaks the antenna, the mode and the direction. Front, Rear, Closing and Away ship; drop your own Stationary, Opposite and Same clips into nui/sounds/ for the full three-word phrase.
• Start-up: every lamp lights and 888 shows in all five windows for three seconds.

#Plate reader

An optional overlay showing the plate each antenna is reading, with a freeze per side (/togglepr2x to show or hide). By default (Config.alpr.provider = 'c3r') every new plate runs through c3r's own records, with no CAD needed: stolen cars, BOLOs, expired registration and no insurance raise an in-game alert, and a flagged car flashes on the map. It also turns up the odd stolen or expired car in traffic. See With CODE3RESPONSE.

Set the provider to 'cde' or 'imperial' to use your CAD instead: stolen, impounded, expired registration, no insurance and any other flag your CAD returns raise an alert, and can be posted to Discord. ImperialCAD also reports on the owner (wanted, licence revoked, expired or missing).

CAD results are cached, but locking a plate always asks the CAD fresh. CAD credentials go in server.cfg, never in the resource; setup is in the comments at the bottom of shared/config.lua, and works the same as the Seeker Dual's.

#What gets saved

Everything you set is remembered per player and comes back after a restart or rejoin: zones, XMIT/HLd, MOV/STA, PS BLANK, the whole Operator Menu, volumes, stopwatch distance, speed unit, plate reader, Doppler, and where the display, plate reader and remote sit.

Four things don't come back, on purpose: the power switch (it always starts off), locks, live readings, and where you were in a menu.

On the real unit a power-on resets your zones to factory positions. Here it doesn't; set Config.rememberOperationalState = false if you'd rather it behaved like the real thing.
