10 Best Driveway Alarms 2025 in the UK

The HOSMART 1/2 Mile Long Range Wireless Driveway Motion Alarm System is designed for those needing reliable perimeter security. It features a substantial detection range of up to 1/2 mile in open space, which is impressive and doubles what many competitors offer. The wireless nature of the system makes installation straightforward, aided by the Quick Start Guide. The device comes with a single base receiver and one sensor, and it can be expanded to include up to four sensors and unlimited receivers, which is beneficial for larger properties or users needing comprehensive coverage.

The alert type includes fun and unique chimes, which can help differentiate between different areas of detection, adding to its user-friendly design. The system is powered by AA batteries, which are included, and the sensor can detect motion from humans, cars, and large animals, offering versatile security options. The weather resistance is another strong point, with the sensor's industrial-grade PVC housing and rubberized seals ensuring it can withstand various harsh weather conditions like rain, snow, and extreme temperatures. Adjustability in sensitivity and detection angles helps minimize false alarms, which is a common issue for motion sensors.

Users should note that while the system has a strong wireless range, the effective range may be reduced in settings with obstacles such as trees and buildings. Additionally, the product's delivery limitations should be considered for those outside mainland UK. A solid customer rating of 4.1 out of 5 stars from over 2,300 reviews suggests the HOSMART system is generally well-regarded but may not be perfect for all environments or users. The provided 2-year warranty and 90-day risk-free offer add to the product's reliability and appeal.

The Mydome Wireless Driveway Motion Alarm offers a user-friendly solution for monitoring outdoor areas like gardens and driveways. With a detection range of up to 300 metres, it is well-suited for covering a sizeable perimeter, making it effective at alerting you to visitors or potential intruders. The system uses a PIR (passive infrared) sensor, which is designed to balance performance and battery longevity. It's a wireless setup, relying on replaceable alkaline batteries, making installation more flexible without the need for cumbersome wiring.

One of its standout features is its expandability. The system can accommodate additional sensors and receivers, allowing you to customize your security based on the specific needs of your property. For those with several vulnerable entry points, this feature makes the Mydome system particularly appealing.

Alerts are provided both visually and audibly through a plug-in receiver, which includes a high-quality speaker with five volume levels, including a mute option. This variety in alert type ensures you can tailor notifications to your preferences, though it's worth noting for some users, the range of chime options may become repetitive. Another plus is the weather resistance of the sensors, making them viable for outdoor use in various climates. The ease of installation, thanks to the rotatable mounting plate and options for adhesive or screw mounting, enhances its accessibility for DIY users. However, while the system is generally well-received, some may find the need to purchase additional receivers or sensors to cover larger properties a bit of an added expense. Additionally, while the battery longevity is optimized, regular checks and replacements are necessary to ensure continued optimal performance.

The Mydome Wireless Driveway Motion Alarm is a versatile and effective choice for those seeking to secure outdoor areas with a straightforward installation and customizable alert system. It may particularly suit users looking for an expandable, wireless security solution with minimal maintenance.
