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

 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). Set Config.alpr.provider to 'cde' or 'imperial' and every new plate runs through your CAD: stolen, impounded, expired registration, no insurance and any other flag your CAD returns raise an in-game alert, and can be posted to Discord. ImperialCAD also reports on the owner (wanted, licence revoked, expired or missing).

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.
