However mine works in a house the hub is upstairs. **Q: Can entry sensor be used on outbuildings** A: You can use the sensors anywhere within 100ft of your base station, so this would depend how far away the outbuilding was. You would also need to place the entry sensor on the interior of the building to protect it for the weather as they aren't designed for external use. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Intuitive, easy start, quick delivery *by D***N on 29 March 2026* Fitting most simple yet has security fidelity Price cheaper than manufacturers site Batteries and fixing included All good and delivery as quick and efficient as I expect from amazon Simple to install and operate and no false alarms yet ### ⭐⭐⭐⭐⭐ Great quality *by H***N on 6 December 2025* Easy to set up, no issues ### ⭐⭐⭐⭐⭐ Recommended - good quality and easy to install *by J***N on 5 February 2026* Very good, sensitive and easy to install.
