Frequently Asked Questions

FAQ

Who is Heimdall for?
The first version of Heimdall is designed for people who spend time alone at rural outdoor shooting ranges and don't want to be sitting ducks while concentrating on their target practice.
How does it work?
You place Heimdall on the ground and wirelessly connects it to your Android or iOS device. Heimdall then continuously monitors the ground for vibrations and sends the signal in real-time to your device. If it detects a footstep-like event it will notify you using audio feedback.
Why not just use a regular motion sensor?
Unlike a regular motion sensor (PIR), Heimdall has a long detection range, excellent outdoor performance, and can detect movement from any direction without the need for line-of-sight. And since you can hear the footsteps, you get more insight into the detected movement which increases your situational awareness.
