Protect your caravan, campervan or motorhome — and the annexe, awning and storage around it — without depending on mobile coverage, a Wi-Fi hotspot or a monthly monitoring subscription.
If you are looking for a caravan alarm in Australia, the key requirement is that it works off-grid — most caravan parks have patchy Wi-Fi and remote campsites have none. K9-Alert uses a direct wireless sensor-to-speaker link with no internet dependency.
Smart alarms, app-connected cameras and cloud-monitored devices all fail in the same way on the road: they depend on a stable internet connection that caravan parks and campsites rarely provide. K9-Alert's direct sensor-to-speaker radio link works regardless.
Smart alarm systems and camera apps lose connectivity — and their deterrent value — the moment Wi-Fi drops. K9-Alert has no dependency on the internet: the sensor and speaker communicate directly via radio frequency.
K9-Alert supports multiple sensors paired to one speaker — protect the van door and the annexe entrance with a single speaker inside the van.
Most caravan theft and break-ins are opportunistic — someone walking through looking for an easy target. A bark in response to approach signals the van is occupied and watched.
No permanent installation. No drilling. Place the sensor outside; keep the speaker inside the van. One button on the remote to arm and disarm.
Position the sensor to cover the main van door approach. Mount temporarily with the included bracket — no tools, no screws into your van wall.
A second wireless motion sensor paired to the same speaker covers the annexe entry. The speaker inside triggers barking whichever sensor detects motion.
Aim a sensor across the approach to the underfloor storage or rear hatch where bikes, generators and gear are stored.
One button on the key-ring remote arms and disarms the system. No need to walk past the sensor when you step out and back in.
Most caravan alarms either require installation or depend on a connected phone. K9-Alert requires neither.
| Concern | Smart/app-based alarm | K9-Alert |
|---|---|---|
| No Wi-Fi at campsite | App alerts stop working — alarm may still sound but you won't be notified | Works entirely offline — no internet needed |
| Protecting the annexe | Single-zone — van door only | Multiple sensors, one speaker — van + annexe covered |
| Moving between sites | Must reconfigure Wi-Fi at each location | Nothing to reconfigure — plug in and arm |
| Installation | Often requires hardwiring or permanent mounting | No tools, no drilling, fully portable |

K9 Alert has worked as advertised. The remote control is good. The range of the sensor is longer that I thought, facing it 30deg down still gives 8 meters range for an approaching pedestrian. Battery life for speaker and sensor is good so far. I've had 2 visitors so far ask where I bought it.
Very practical little security device. Easy to set up and the barking sound is surprisingly loud and realistic. I use it near the front door at night and it gives an extra sense of security without needing complicated installation. Good value for the price and works as described. Fast delivery too. Recommended. Good condition
Easy to set up and very practical. The barking sound is loud and realistic enough to act as a deterrent, especially for a garage, shed or front entry. I like that it does not need Wi-Fi and comes with a remote control. It is not a full security system, but for extra peace of mind it does the job well.
K9-Alert travels well because it needs no signal, power or installation. It protects the approach to the van while you are on site; it does not protect a van that is left in storage or towed away. Here is where it fits and where it does not.
Under the awning or inside the annexe, set the sensor 50–80 cm high on a removable mount, angled slightly down and across the step to the van door. Keep it under the awning, out of rain and out of the morning or afternoon sun, and point it at your own pitch rather than the neighbour’s. The speaker goes inside the van. Arm it with the remote when you go to bed or leave the site, and disarm it before you step outside.
For the van door alone, the standard kit (A$95) is enough. To cover both the door and the annexe entrance, take the 2-zone kit (A$134.95). If you also want the storage hatch or the area around the tow vehicle watched, the 3-zone kit (A$169.95) gives you three sensors on one speaker. Everything runs on batteries, so there is nothing to plug in at a powered or unpowered site.
Yes. The wireless sensor communicates with the speaker via radio frequency — no internet, no mobile data, no Wi-Fi required. It works at remote campsites with no coverage.
Yes. K9-Alert supports multiple sensors paired to one speaker. Place one sensor at the van door and one at the annexe entrance — the speaker triggers barking from either.
K9-Alert has adjustable volume. Set it at a level audible within the van and immediately outside without being disruptive. It only triggers when motion is detected — not continuously.
The sensor is battery powered. The speaker plugs into a power point — in a van this can be a 240V socket or a 12V adapter. Check the product specifications for power requirements.
Many GPS trackers and connected caravan alarms charge a monthly fee for the SIM and app. K9-Alert has no subscription, Wi-Fi or app: a sensor at the door or annexe triggers barking from the speaker inside the van. It does not track the caravan or send alerts, so add a tracker if theft of the whole van is your main worry.
