quoteIf your motorhome’s base vehicle has an immobiliser, the next logical step is to add a motorhome alarm.
There’s a good chance your motorhome came with some kind of engine immobiliser. It might have come as a surprise, though, to find out you’d have to fork out for some kind of motorhome alarm system.
And choosing the right one may not be so easy. First, it depends on the type of motorhome you own. For example, if you own an elevating roof campervan, it’s akin to a car and can easily be kitted out with a standard aftermarket alarm system, although you might not be able to use it, for example, when you’re sleeping in your ‘van. You might want to bear in mind how often you hear a car alarm go off only for it to be ignored.
As far as high-top van conversions and coachbuilt motorhomes are concerned, you’re looking at very specialised vehicles for which, frankly, an alarm system that was initially designed for cars night not be suitable without some modifications.
And bear in mind that having an alarm system might be a condition of your motorhome insurance cover, and the likelihood is then that your insurance company will want the motorhome alarm to be of a certain standard, most likely Thatcham Category 1 approved.
Meet Thatcham
Set up by leading car insurance companies as an independent, not-for-profit organisation, Thatcham is a recognised leader in assessing vehicle alarms. A Thatcham Category (CAT) 1 approved security system combines an alarm and an engine immobiliser. Find out more at www.thatcham.org.
What is CAT 2-1?
Thatcham states that as long as your motorhome has a factory-fitted immobiliser, adding to it with what’s known as a Thatcham Category 2-1 approved aftermarket alarm essentially takes the security fitted on your motorhome up to Thatcham Category 1 approved standard. A list of such alarm systems can be generated here.
But, do note, not all will be suitable to your particular motorhome. As Thatcham itself puts it: “Generally installer companies will take an LCV (light commercial vehicle) Thatcham CAT 1 device (which only covers the opening of the front doors and interior protection of the driver’s cabin) and add additional detectors where required for the openings and interior protection of the motorhome.”
Caravan Guard offers a 19 percent insurance premium discount for motorhomes fitted with a Thatcham Category 1 approved security system and will accept Thatcham Category 2-1 upgrade devices which can be fitted to motorhomes already fitted with Thatcham Category 2 approved, or factory-fitted immobilisers, to attain Category 1 status.
Top motorhome alarm tips
- Ask your motothome dealer about any specific aftermarket security systems it recommends and/or is authorised to fit. For example, Brownhills of Newark has been fitting its own Sigma Thatcham CAT 1 system for over a decade.
- Make sure any installation is carried out by authorised, professional installers. Also, insist on getting an installation certificated once you’re happy with the finished work.
- Before a motorhome alarm is fitted, do check the location of warning lights and whether they’ll be visible with the blinds drawn etc.
- Other considerations include: can extra features like bike locks be added. Plus what protection is provided for cab and habitation doors, bonnet, exterior lockers, windows, rooflights and so on?
- For many motorhomes perimeter protection is essential. It means an alarm can still be armed when you or your pets are on board.
- Good quality stickers warning of the presence of a motorhome alarm system are a useful visual deterrent.
- Check what level of warranty you get with your alarm.
- It should go without saying but, if you have an alarm system fitted, make sure you use it, particularly when in storage.
- Always look after your motorhome keys. Electronic theft is on the rise. At its most sophisticated, this involves cloning keys so theft simply bypasses any alarm system. Do note, also, that stealing original keys is another easy first step to pinching the whole vehicle – look after your keys, including spare sets!

Phantom Sentinel
This latest product from motorhome and caravan security specialist Phantom combines a Thatcham CAT 1 dedicated motorhome alarm and an S7 approved tracking system. It’s operated by a remote control or the base vehicle’s original key. But, it can also be controlled via an app, suitable for both Android and Apple iOS, or a remote access fob.
A series of sensors offer protection of cab and habitation doors and windows, plus bonnet, with internal ultrasonic sensors. Extra sensors and switches can be added to the garage or external locker doors too. The internal motion detectors can be disarmed easily when you’re on board at night, and if you have pets, but still keeping the door and window sensors armed.
The Sentinel has an intelligent battery back-up if power is lost from the main battery. It also records all journeys and alarm activity, monitors your motorhome’s battery level with alerts, plus mileage and alarm status. It will tell you when the alarm was last armed and whether it was by remote unit or via the app. The tracker will also alert you if your motorhome is moved or towed and the MyPhantom app and web portal lets you keep an eye on the current location of your motorhome (and more!)
Features also include: Spare remote, 30-day battery level, bonnet protection, extra PIR sensors or mag door switches, free fitting.
Expect to pay: £699 fitted (plus annual tracking device subscription)

Van Bitz Strikeback 
Exclusive to Van Bitz, the Strikeback is produced solely for motorhomes and takes a whole day to fit at its premises (overnight camping is available here). It’s a full facilities, approved Thatcham CAT 2-1 upgrade, an alarm that covers the motorhome’s living quarters, cab, bonnet, external locker doors, and more, complete with full “sleep mode” as well as offering all manner of specifically motorhome-friendly features, such as an interior movement sensor that, in Van Bitz’s words, sets up a “radio wrap” within the vehicle – far more sophisticated than the usual ultrasonic sensors that are often fooled by the slightest of movements, or even a heating system in operation.
Features also include: Accessory protection loop, international warning stickers
Expect to pay: From £599 fitted

Cobra Can Alarm
This is classified by Thatcham as a CAT 2-1 upgrade and is suitable for Fiat Ducato/Peugeot Boxer-, Mercedes Sprinter- and Ford Transit-based motorhomes from 2006 onwards and usually means you don’t need extra key fobs as it uses the original motorhome key to arm and disarm the alarm.
Features include the facility to disarm the internal ultrasonic sensors when your vehicle is occupied, although that still gives you perimeter protection, and an anti-hijack battery back-up. The warranty is pan-European, valid across 36 countries, so you can have it checked and any issues resolved locally wherever you are. Options also include the facility to add a gas attack sensor, external locker protection and more.
Features also include: LED/control button, panic button facility, emergency PIN code entry, three-year warranty.
Expect to pay: £339.99 fitted

Sigma S37
The Sigma S37 alarm system is a Thatcham Cat 2-1 upgrade alarm system from auto security specialists, Scorpion Automotive, specifically designed for a motorhome to improve its security and protection.
The system comes with front interior ultrasonic sensors, battery backup siren, door open detection via the vehicle’s CAN Bus system, and bonnet detection. When the alarm triggers it will sound the external siren and flash the indicators.
The Sigma S37 alarm system works with an existing OEM remote keyfob. For vehicles supplied with only one OEM remote keyfob, an extra four-button upgrade remote is available. This supports locking/unlocking of your vehicle as well as arming / disarming of the alarm. An in-dash override receptacle with LED is also supplied to allow de-activation of the internal sensors whilst the habitation area is occupied.
The system can also be upgraded for ultimate protection with the Thatcham Approved ScorpionTrack S7-ALS or S5-VTS+ tracking systems. Once either of these systems has been installed alongside the Sigma S37 alarm, you’ll not only always know where your vehicle is, but in the event of theft, you have the opportunity of it being recovered quickly. Alerts can also be received via the ScorpionTrack App, should the alarm be activated whilst you’re away from your motorhome.
Features also include: OEM key remote to arm and disarm, extra four-button remote, touch key over-ride, built-in ultrasonic sensors, LED status indication, upgradable with extra sensors, output for Scorpion tracker system.
Expect to pay: From £499

Will it affect my insurance?
If you choose to retrofit an alarm, make sure it meets your insurer’s requirements. Thatcham Category 1 approved alarm systems will give you a healthy discount off your motorhome insurance policy with Caravan Guard. Note as the Phantom Sentinel includes both a Thatcham S7 approved tracking system and Gemini 2-to-1 alarm upgrade it would qualify for Caravan Guard’s 25% motorhome tracking device discount.
If you are claiming a discount for or if it’s a requirement of your policy to have a Thatcham Category 1 approved security system fitted to your motorhome you must also make sure your alarm is always activated when your motorhome is unattended and the alarm is fully maintained, as per the manufacturers’ recommendations. Therefore, during winter storage, always make sure there’s enough charge in your battery to activate the alarm in the event of a break-in.
Discounts are subject to underwriting terms and conditions. Minimum premiums apply.
Over to you…
Have you fitted a CAT 1 motorhome alarm system, if so which, and let us know if you’ve been impressed by it? Do you feel alarms offer a good level of security?
Feel free to add your comments below.
All very well – until your alarm/immobiliser starts to falter. We have had to call the AA twice and been bumpstarted once when our immobiliser (Sigma fitted to Peugeot Boxer by Brownhills) has refused to allow our 13 year old Elddis Suntor to start. It’s an intermittent fault so diagnosis by the AA hasn’t fixed the problem. If you can recommend a competent auto electrician who can check it out thoroughly locally that would be a great help. We don’t really want to have to take it back to Brownhills!
This article very informative I have clear my mind about this topic thanks
Having had a Transit-Based motorhome stolen en-route back from Italy (stolen in Birmingham) we know all about the reasons for having an alarm fitted. The van was parked outside on our Son’s driveway. He has a dog that barks at the slightest sound but was silent all night. Ordered new motorhome with a Cobra Cat-1 alarm now and would urge every motorhome owner to do the same. We were left with the clothes we were standing up in, toiletries, a duvet, a sheet and the hookup cable that the thieves simply unplugged. Had to catch a train back to Yorkshire and had lost so much stuff. Also advise making sure that portable items such as laptops, tablets, cameras, generators, binoculars (yes, we had all those stolen too) are all covered by household contents insurance whilst out of the house (we didn’t and regret that now). Hindsight is such a wonderful thing.
Sorry to hear about your theft Richard but thanks for sharing your story and advice.
All motorhomes (and cars) with air-conditioning fitted should be run at least one time a month. This keeps oil on the air conditioning compressor oil seals. If they get too dry they are damaged once run and that allows the gas to escape. An expensive business. So it is not only batteries. The batteries can be kept up with a power connection via chargers. While the tyres are now resistant to flat patches forming again, it is prudent to look after them. Small time/fuel cost for large savings otherwise. Some of these modern alarm units have a very small drain in any event, about 1mA/hour
We are new motorhome owners of a Sunlight t68 based on a Fiat Ducato, and I was surprised that a high level of security was not standard. Powders quoted me £795 to add a category 1 alarm after looking at the list this seems expensive but do we risk affecting the warranty by going to someone else?
Hi Susan, you’re best seeking advice from your dealership about the warranty as they are best placed to advise.
It makes sense to invest in an alarm system
It makes sense to have one!!
We’ve had a Cobra A4615 fitted to our Bessacarr Hi Style which does the business for this size of vehicle. However, in the article this model only shows the siren, control unit and 2 x ultra sonic sensors for the interior. The system is wired to the two front doors via the standard fit push pins for the interior light which takes care of the cab entry. Included in the kit which cost £500 all inclusive were door contacts for the habitation door a door contact for the offside pod door. When in use we can disable the interior ultra sonic sensors but still have fully functioning door contacts all round. A good buy. As for battery drain, we take the vehicle out at least once a month for a run anyway.
I agree. Battery drain is very significant if your Motorhome is in storage & reliant on the engine battery to keep the alarm going. I’ve found that 4 weeks is as long as I dare leave it without taking it out for a run (which is good practice anyway to prevent tyre/brakes/suspension & bearing damage).
I invested in a solar panel to avoid panic if I strayed over my 4 week limit.
Standard car alarm is not suitable for ANY campervan/motorhome you need a dedicated combination unit with minimal battery drain
