A wheel clamp and hitch lock stop opportunistic theft, but a proper alarm system does something those can’t: it fights back. The best caravan alarm systems combine motion detection, intrusion sensors, and brake immobilisation to make stealing your van a genuinely terrible idea. Some will lock the electric brakes the moment someone tries to tow away. Others will scream at 105dB and flash every light on the van.
The Australian caravan alarm market is dominated by two brands: RVsecure and WiTi. Both are Australian-designed, both integrate with your van’s electric brakes, and both offer expandable systems you can build out over time. The right choice depends on your setup, your budget, and whether you want GPS tracking baked in.
Here’s what’s worth your money in 2026.
What To Look For In A Caravan Alarm
Not all caravan alarms are the same. A decent home alarm bolted into a van isn’t going to cut it. You need a system designed specifically for caravans, because caravans move, bounce, and sway in the wind. A system that doesn’t account for that will false alarm every time a gust hits your awning.
Anti-Tow / Brake Immobilisation
This is the headline feature that separates caravan-specific alarms from generic security systems. Both RVsecure and WiTi integrate with your van’s electric brakes. If someone tries to hitch up and tow away, the system locks the brakes, making the van virtually impossible to move. It’s the single most effective anti-theft feature available.
Intrusion Detection
PIR (passive infrared) motion sensors detect movement inside the van. Magnetic door switches detect when a door or hatch is opened. Together, they cover both break-in attempts and someone who manages to get inside. The best systems let you add more sensors to cover tunnel boots, toolboxes, and other entry points.
Arming Modes
This matters more than people realise. A “night mode” that keeps the door sensors armed but disables the internal motion sensor means you can sleep in the van with the alarm protecting the outside. Without this, you’d trigger your own alarm every time you got up to use the toilet.
Expandability
Your base kit covers the basics, but the ability to add more sensors over time is valuable. Extra PIR sensors for the tunnel boot, additional door switches for hatches, panic buttons for emergencies. Both RVsecure and WiTi support expansion, but the number of zones differs.
GPS Tracking
Both systems offer GPS as an add-on. GPS won’t stop a theft, but it dramatically increases your chances of recovery. If someone does manage to drive off with your van, real-time tracking means you (and the police) can follow it. GPS tracking requires an ongoing subscription.
Both RVsecure and WiTi require your caravan to have electric brakes for the anti-tow brake locking feature to work. If your van doesn’t have electric brakes (some smaller camper trailers and older vans don’t), the alarm and intrusion features will still function, but you won’t get brake immobilisation.
RVsecure PlatinumX
✔ Pros
- Expandable to 16 zones for comprehensive coverage
- Night mode keeps perimeter armed while you sleep inside
- LCD display on control unit
- Panic button included as standard
- Code-hopping transmitters prevent code grabbing
- Built-in digital level (handy bonus)
✗ Cons
- GPS is an add-on, not included (~$300 + $100/yr subscription)
- Installation is more involved than WiTi
- No brake locking without electric brakes
The PlatinumX’s three arming modes are a genuine standout. Normal mode arms everything. Silent mode triggers the strobe but no siren (useful in quiet caravan parks where you don’t want to wake the neighbours over a possum). Night mode disables the internal PIR so you can move around inside the van while keeping the doors, hatches, and anti-tow protection active. That last one is essential for anyone sleeping in the van.
One bonus feature worth mentioning: the PlatinumX has a built-in digital level. It won’t replace a proper levelling system, but it’s a handy extra when you’re setting up camp.
WiTi Anti-Theft System
✔ Pros
- World-first brake immobilisation technology
- Designed and made in Australia
- Expandable to 20 sensors
- Integrates with WiTi brake controller and GPS ecosystem
- 2023 WA Innovator of the Year award winner
- Proven real-world track record
✗ Cons
- No panic button included (RVsecure includes one)
- Cannot wire into motorhome braking circuits
- GPS requires ongoing subscription ($228/yr)
WiTi has real-world runs on the board. One owner reported their alarm going off at 3:30am when a couple tried to break into their van in a suburban street. The thief tried the door, an accomplice unplugged the power cord, and the alarm activated instantly, sending both of them running. That’s exactly how these systems are supposed to work: the thief never even got inside.
The gyroscope is sensitive enough to detect sharp knocks and bangs from someone trying to force a toolbox or pry a door, not just full towing attempts. It’s also worth noting WiTi won the 2023 WA Innovator of the Year award, which speaks to the engineering quality behind the product.
WiTi All-In-One Bundle
✔ Pros
- Three products in one integrated system
- Significant saving vs buying separately
- GPS alerts sent to your phone via app
- Wireless brake controller is a standalone upgrade
- Hill descent control and brake smoothing included
✗ Cons
- Higher upfront cost
- GPS requires $228/year subscription
- Overkill if you already have a brake controller
WiTi Anti-Theft cannot be wired into motorhome braking circuits. If you have a motorhome, the RVsecure PlatinumX is the better option as it has a motorhome-specific variant. WiTi does offer a separate motorhome alarm (without brake integration), but the brake immobilisation feature is not available for motorhomes.
Accessories & Add-Ons
Both systems are expandable. Here are the key add-ons worth considering.
RVsecure Add-Ons
SafeGuard Emergency Switch (~$80) — A dedicated panic button. Press it whether the system is armed or not, and the siren sounds and strobe activates immediately. Useful if you feel threatened at camp, or if someone is trying to break in while you’re inside the van. The PlatinumX includes one, but you can add extras in different locations.

Additional Remote (~$49) — Handy if you’re travelling as a couple and both need a remote, or as a spare. The PlatinumX comes with two 4-key remotes, but a third is cheap insurance against losing one in the middle of nowhere. Check price at Caravan RV Camping →
WiTi Add-Ons
Additional PIR Motion Sensor (~$49) — The base kit includes one PIR sensor. Add extras to cover the tunnel boot, front storage compartment, or annex area. WiTi supports up to 20 paired devices, so you can get comprehensive coverage. Check price at Caravan RV Camping →
Additional Remote Controls — Spare remotes for the WiTi system. The base kit includes two, but extras are worth having as backups. Check price at Caravan RV Camping →

Which One Should You Get?
Both RVsecure and WiTi are excellent systems, and you genuinely can’t go wrong with either. The decision comes down to a few factors.
Choose the RVsecure PlatinumX if you want the most expandable system with the widest range of arming modes. The 16-zone capability means you can add sensors to every hatch, toolbox, and compartment over time. The night mode, panic button, and LCD display are features WiTi doesn’t match. It’s also the only option with a dedicated motorhome variant.
Choose WiTi if you value the integrated ecosystem. If you’re already running (or planning to buy) a WiTi wireless brake controller, adding the anti-theft system is a no-brainer because everything talks to each other through WiTi’s closed Wi-Fi network. WiTi also supports more individual sensors (20 vs 16), and the gyroscope sensitivity is genuinely impressive, picking up knocks and bumps as well as full towing attempts.
If you’re setting up a brand new van, the WiTi All-In-One Bundle is hard to beat for value. Getting the anti-theft, brake controller, and GPS tracking in one integrated package saves you money compared to buying separately, and eliminates compatibility worries.
Whichever system you choose, pair it with physical security: a wheel clamp, hitch lock, and visible deterrents. An alarm system works best as part of a layered security approach, not as your only defence.
