1. Viper 3105V: Best Overall
In our evaluation, the Viper 3105V stands out as the most reliable all-around motorhome alarm system. It features a two-way LCD remote that confirms arming, disarming, and alarm triggers from up to a mile away, which is ideal for large campgrounds. The system includes two adjustable shock sensors and a 120dB siren, plus a starter kill relay for added theft prevention. Owner feedback consistently praises its range and sensitivity adjustment.
However, the remote is somewhat large and may not fit easily in a pocket. Also, the system lacks smartphone integration, which some modern users prefer. If you absolutely need app control, consider a smart alarm instead. But for pure RF performance and proven reliability, this is our top pick.
- Two-way communication with LCD remote confirms alarm status up to 1 mile away.
- Includes two adjustable shock sensors and a 120dB siren.
- Starter kill relay prevents engine start when armed.
Pros: Excellent range and two-way confirmation.; Easy to install with detailed instructions.
Cons: Remote can be bulky for some users.
2. Compustar CS7900-AS: Best with App Control
For motorhome owners who want modern connectivity, the Compustar CS7900-AS is a strong choice. It pairs a traditional two-way remote with the DroneMobile app, letting you arm, disarm, and track your vehicle from anywhere with cellular coverage. The system includes a shock sensor, 120dB siren, and starter kill. In our research, owners appreciated the GPS tracking and geofencing alerts.
The main drawback is the ongoing subscription fee for the app after the first year, which adds to the total cost. Also, installation is more complex due to the cellular module. If you prefer a one-time purchase with no recurring fees, a simpler system might be better. But for remote monitoring and control, this is a top performer.
- Smartphone control via DroneMobile app (subscription required).
- Two-way remote with 1-mile range and confirmation.
- Includes shock sensor, siren, and starter kill.
Pros: App control allows remote arming and GPS tracking.; Long range remote included.
Cons: App subscription costs extra after first year.
3. Avital 4105L: Best Budget
The Avital 4105L delivers essential two-way security at a lower price point, making it an excellent value for budget-conscious motorhome owners. It includes a dual-stage shock sensor, starter kill, and a 2-way remote that confirms commands up to half a mile. Based on owner feedback, it is straightforward to install and reliable for daily use.
However, the range is noticeably shorter than competitors like Viper, and the remote lacks a display. The siren is also less loud at 110dB. If you need maximum range or smartphone integration, look elsewhere. But for basic protection without breaking the bank, this is a solid choice.
- Two-way remote with LED confirmation and 1/2 mile range.
- Dual-stage shock sensor with adjustment.
- Includes starter kill relay and programmable outputs.
Pros: Very affordable for a two-way system.; Reliable performance for the price.
Cons: Range is shorter than premium models.
4. Directed Electronics 5305V: Best for Large RVs
For large motorhomes where range and durability matter, the Directed Electronics 5305V is a top contender. It features a two-way LCD remote with a 1-mile range and a 6-tone siren that can be customized. The system includes dual shock sensors and a starter kill. In our evaluation, its robust construction and strong range make it ideal for bigger vehicles.
The main downside is the cost, which is higher than many alternatives. Additionally, the remote is large and may not appeal to those wanting a sleek design. If you have a smaller RV or a tighter budget, a simpler system might suffice. But for maximum coverage and reliability, this is a great option.
- Two-way LCD remote with vehicle status display.
- Dual adjustable shock sensors and 6-tone siren.
- Starter kill and programmable output for extra sensors.
Pros: Very long range and clear remote display.; Durable build quality suitable for RV vibrations.
Cons: Higher price point.
5. Python 5706P: Best with Smartphone
The Python 5706P combines a modern two-way remote with smartphone capabilities through the DroneMobile app. It offers a 1-mile range remote and the ability to control the system from anywhere via cellular. Owners praise the intuitive remote design and responsive app. The system also includes a shock sensor and starter kill.
Like other DroneMobile systems, the app requires a subscription after the first year. Some users also reported occasional connectivity delays. If you don’t want ongoing fees, consider a non-app system. However, for those who value remote control and monitoring, the Python is a capable choice.
- Smartphone control via DroneMobile (subscription after first year).
- Two-way remote with 1-mile range and 5-button design.
- Includes shock sensor, siren, and starter kill.
Pros: Sleek remote and app integration.; Easy to use interface.
Cons: DroneMobile subscription required for app features.
6. CrimeStopper RS7-G5: Best DIY Install
For DIY-minded motorhome owners, the CrimeStopper RS7-G5 is designed with a plug-in harness that simplifies installation. It includes a two-way remote, dual zone shock sensor, and a tilt sensor that can alert you if the vehicle is jacked up. Owner reviews highlight its ease of setup and the tilt sensor as a useful addition for RVs.
However, the range is limited to half a mile, and some users noted that the remote feels less durable than premium brands. The siren is also on the quieter side. If you need professional-grade durability or longer range, this may not be ideal. But for a straightforward DIY project, it works well.
- Two-way remote with range up to 1/2 mile.
- Dual zone shock sensor and tilt sensor included.
- Plug-in wiring harness simplifies installation.
Pros: Easier to install than many competitors.; Includes tilt sensor for wheel theft protection.
Cons: Build quality feels less robust.
7. AUTOWIT RV Security System: Best Simple Add-On
The AUTOWIT RV Security System is a simple, wireless add-on that is perfect for renters or those who want minimal installation. It includes a motion sensor, door/window sensors, and a key fob with a 100dB siren. In our research, owners appreciated the peel-and-stick setup and the ability to add more sensors.
However, the range is limited to about 200 feet, and there is no two-way confirmation, so you cannot verify arming status remotely. The siren is also less loud than hardwired systems. This system is best as a supplemental alarm for basic deterrence, not as a primary security solution for high-theft areas.
- Wireless motion sensor and door/window sensors.
- 100dB siren and remote key fob.
- Easy peel-and-stick installation, no wiring.
Pros: Very easy to install without tools.; Affordable and expandable with additional sensors.
Cons: Short range and no two-way confirmation.
Frequently Asked Questions
What should I look for in a motorhome alarm system?
Key features include a two-way remote (confirms arming/disarming), shock sensors to detect glass break or impact, a loud siren (110dB+), and a starter kill relay. For large RVs, consider range (1 mile preferred) and smartphone app integration for remote monitoring. Durability against vibrations and weather is also important.
Can I install a motorhome alarm system myself?
Many aftermarket systems are DIY-friendly with plug-in harnesses and detailed instructions. However, if your motorhome has a complex electrical system or you are not comfortable with wiring, professional installation is recommended to avoid damaging the vehicle or voiding warranties.
Do motorhome alarm systems work with RV batteries?
Yes, most systems are designed to work with 12V DC power, which is standard in RVs. Some may require a constant power source, so ensure the system does not drain your house battery when parked for long periods. Many have low-power standby modes.
Will an alarm system prevent theft of my motorhome?
No alarm system can guarantee prevention, but a visible system with a siren and starter kill acts as a strong deterrent. Systems with GPS tracking (via app) can help recover a stolen vehicle. For maximum protection, combine an alarm with physical locks and steering wheel locks.
What is the difference between one-way and two-way remotes?
A one-way remote only sends commands to the vehicle. A two-way remote sends commands and receives confirmation (e.g., lights flash, remote beeps) that the command was executed. Two-way is more reliable because you know the system is armed or disarmed, especially at longer ranges.
Our Verdict
After comparing specifications, industry standards, and owner feedback, the Viper 3105V earns our top recommendation for its excellent range, two-way confirmation, and proven reliability. For those who want smartphone control, the Compustar CS7900-AS is a strong runner-up, though it requires a subscription for app features. Choose based on your need for range, connectivity, and budget.
