One Plus - 4G Immobiliser with Camera and Automatic Night Protection
It arms itself when you go to bed. Because that is when they come.
The night window
Most vehicles are stolen between 1am and 5am
You are asleep. Your key is on the hall table, broadcasting. One Plus does not wait for you to remember to arm it — you set the hours once, and every night the engine circuit locks itself down until morning.
| 20:00 | IMMOBILISED — AUTOMATICALLY | 07:00 |
Set your own window in the app. Outside those hours the system behaves normally — night shifts, early starts and airport runs are a two-second override on your phone.
What it stops
Relay and keyless attacks
Thieves amplify your key signal from inside the house and the car unlocks and starts. One Plus does not care - the starting circuit stays physically cut until it recognises your authorisation.
Unauthorised use
Anyone holding the key still needs the tag, the trusted phone or Face ID. Useful for shared vehicles, work vans and anyone who has ever handed keys to a garage.
Night-time theft attempts
Automatic immobilisation during your chosen hours, plus motion alerts with footage sent straight to your phone the moment something moves around the vehicle.
Theft in progress
If it is already moving, Stop Engine works remotely from the app, and anti-hijack blocks the engine safely when the authorised tag leaves the vehicle.
Full app control
Your car, in your pocket, over 4G
Permanent 4G connection means the vehicle is reachable whether it is outside your house or three hundred miles away. Open the app to see live camera footage, check the location, lock or unlock the immobiliser, or cut the engine.
Four ways to prove it is you
Wi-Fi tagKeep it on your keyring. Disarms hands-free as you walk up to the vehicle.
Trusted phoneThe system recognises your paired handset and releases the block.
Face IDIdentifies the person behind the wheel before the engine is allowed to start.
App codeYour fallback if the tag battery dies or the phone is flat.

Before you buy — the honest details
Professional fitting included
Fitted by an approved installer, included in the price UK. Once your order is confirmed we arrange the date and location through eBay messages. Typical fitting time is 4 hours. Prefer your own auto electrician? Message us before ordering.
The 4G features need a subscription
Remote access, live camera view, real-time alerts and cloud storage run over the mobile network and require an active subscription: £15/month. The first 1 months are included. The immobiliser, night mode, tag authorisation and local recording keep working either way.
This is not a hotspot
Unlike the DUO range, One Plus does not broadcast Wi-Fi internet to your devices. The 4G connection is dedicated to the security system.
Lawful use
If the camera records inside the vehicle and you carry passengers, employees or paying customers, you are responsible for informing them that recording takes place, in line with data protection rules where you operate.

Questions buyers ask
What if I need the car at 3am?
Override it from the app in a couple of seconds, or use your tag as normal - night mode locks out unauthorised starts, not you.

Will it fit my vehicle?
It is a universal 12/24V system, not model-specific. Send us your registration or the make, model and year and we will confirm before you buy.

Can a thief find and cut it out?
The control unit and the blocking module are fitted separately and concealed, and the wireless link means there is no cable run pointing from one to the other.

Will it flatten my battery?
It monitors vehicle battery voltage continuously and shuts itself down before the battery drops too low to start the engine.

What if there is no 4G signal?
Immobilisation, night mode, tag authorisation and local recording all run on the device itself. Alerts and footage are delivered once signal returns.

How does this compare to the DUO models?
DUO adds a second camera covering the cabin and a Wi-Fi hotspot function. One Plus is the single-unit version with the same immobiliser core - the right choice if you want protection rather than fleet monitoring.
