How to detect drones over your property.
From free to professional: four ways to know a drone is over your home or land, what each one tells you, and what each one misses.
US rules, reviewed by Thalrix, the maker of Tripwire Home. General information, not legal advice.
Short answer: most drones flown in the US broadcast FAA Remote ID. A free phone app can pick it up while you’re watching. A Remote ID receiver mounted outside picks it up day and night and alerts your phone. Drones that don’t broadcast need RF detection or radar, which cost far more.
First, what is Remote ID?
Since March 2024, the FAA has required most drones to broadcast Remote ID: a short-range Wi-Fi or Bluetooth signal, like a digital license plate. It applies to drones that must be registered, meaning anything over 250 grams and any drone flown for work. The broadcast includes:
- the drone’s identification (a serial number or session ID),
- its position, height, speed and direction,
- the location of the pilot’s controller, or for drones fitted with an add-on module, where it took off,
- a time stamp.
It does not include the owner’s name. Police and the FAA can look that up from the ID.
The four ways to detect a drone
1. Eyes and ears (free)
Look for something low that hovers or changes direction suddenly, and listen for a high-pitched buzz. It works if you happen to be outside and looking, and it tells you nothing about who is flying. At night, see how to spot a drone at night.
2. A Remote ID app on your phone (free)
Free apps can show nearby drones broadcasting Remote ID, often with the pilot’s location. The catch: the app has to be open, your phone has to be outside or near a window and in range, and on an iPhone only the Bluetooth signal is heard. Good for a spot check when you see one. More in drone detection app vs. a dedicated detector.
3. A Remote ID receiver mounted outside (for homes)
A receiver mounted high on your house listens all the time, on both Wi-Fi and Bluetooth, and much farther than a phone. When a drone comes near, it alerts your phone wherever you are and keeps a record of the flight. Tripwire Home is built for this: one cable powers it, it shows the flight path and, where the drone broadcasts it, where the pilot is, and the record is dated so you can share it with police or the FAA. It has no camera and no microphone.
4. RF detection and radar (for businesses and critical sites)
RF detectors listen to the radio link between a drone and its controller, and radar sees the drone itself, so both can pick up drones that don’t broadcast Remote ID. They typically cost thousands to tens of thousands of dollars and are used at airports, prisons, utilities and stadiums. For sites, see enterprise Tripwire.
Side by side
| Method | When it works | Tells you where the pilot is | Misses |
|---|---|---|---|
| Eyes and ears | Only while you’re watching | No | Anything high, quiet or out of sight |
| Phone app | Only while the app is open, in range | Usually, if broadcast | Drones without Remote ID; Wi-Fi Remote ID on iPhone |
| Mounted Remote ID receiver | 24/7, alerts your phone | Usually, if broadcast | Drones without Remote ID |
| RF detection or radar | 24/7 | RF often can; radar can’t | Depends on the system; expensive |

Detected one. Now what?
Don’t try to bring it down: damaging a drone is a federal crime, and jamming is illegal. Write down what happened, keep the Remote ID details, and report repeated or threatening flights to your local police. Can someone fly a drone over my house? explains what the law allows.
Common questions
How can I detect drones over my property?
Four ways: watch and listen; use a free Remote ID app on your phone while the drone is in the air; mount a Remote ID receiver outside that listens 24/7 and alerts your phone; or, for businesses and critical sites, RF detection or radar. For most homes, a mounted Remote ID receiver is the practical choice.
What is Remote ID?
An FAA rule that took full effect in March 2024. Drones that must be registered (over 250 grams, or flown for work) have to broadcast their identification, position, height, speed and, for most drones, the pilot’s location, over Wi-Fi or Bluetooth. Anyone with a receiver can pick it up nearby.
Can my phone detect drones?
Yes, with a free Remote ID app, but only while the app is open and the drone is in range. On an iPhone, apps hear only the Bluetooth version of Remote ID. Many Android phones hear both Wi-Fi and Bluetooth.
Can a drone detector see every drone?
No. Remote ID receivers, including every home detector, only see drones that broadcast Remote ID. They miss drones with Remote ID switched off or modified, many small recreational drones under 250 grams, and most government aircraft. RF detection and radar can see more, at far higher prices.
Do security cameras detect drones?
Rarely. Home security cameras point at the ground, are tuned to spot people and cars, and can’t make out a small drone against the sky, especially at night. They also can’t tell you where the pilot is.

Know when a drone is over your home, even while you sleep.
Tripwire Home is a drone detector you mount outside. It alerts your phone when a drone broadcasting Remote ID comes near, with the flight path and, where the drone broadcasts it, where the pilot is. One-time purchase. Alerts need no subscription. No camera, no microphone.
