Drones without Remote ID
Not every drone broadcasts an identification signal. Which aircraft those are, how often it happens and what you can do about it without selling nonsense.

This is the question every serious buyer asks, and rightly so. Detection through Remote ID works because the drone broadcasts. What if it does not?
Which aircraft broadcast no Remote ID
- Home-built aircraft and FPV racers that were never placed on the market and therefore carry no class marking.
- Older consumer drones from before the requirement, some of which broadcast after a firmware update and some of which do not.
- Aircraft where somebody has deliberately disabled or removed the module. That is prohibited, and it happens.
- Very light aircraft under 250 grams in certain cases, depending on class and use.
So we do not say we see every drone. We say we see every drone that broadcasts Remote ID, and at events and business sites that is the large majority.
How often does it happen?
That depends entirely on who is flying. Above a festival it is visitors with an aircraft they bought in a shop, and those broadcast. During our 2026 deployments every detected aircraft broadcast properly. Above a location where someone flies deliberately and prepared, the chance of an aircraft without a signal is higher.
That difference decides whether Remote ID detection is enough for you. For an event, a business site or a solar park, usually yes. For a location whose threat picture includes a motivated adversary, it is one layer among several.
What the alternatives do, and cost
| Method | Sees aircraft without Remote ID | Drawback |
|---|---|---|
| Remote ID reception | No | Depends on what the drone broadcasts |
| RF analysis of control links | Partly | More expensive, more false alerts, no pilot position from unknown protocols |
| Radar | Yes | Far more expensive, needs permits and siting, confuses birds with drones |
| Acoustic | Partly | Short range, poor in ambient noise, so not at a festival |
| Camera with image recognition | Yes | Only with line of sight and daylight, short range, privacy sensitive |
A system that sees everything exists, and it costs a multiple and demands siting and operation that do not fit a three-day event. The honest question is not which method is best, but which fits your risk and budget.
What you do about the remainder
- Treat detection as the layer that removes the known cases. That is the large majority, and it saves your security team a great deal of work.
- Keep visual observation in the protocol for what is left. A guard who knows what to look for beats one scanning the whole sky.
- Record what you do see. A pattern in the known flights says something about the unknown ones too.
- Scale up when the threat picture justifies it, and not before.
We would rather sell a system whose limits you know than a promise that fails the first test. What the DRID does is on the product page, including what it does not do. Not sure whether it fits your situation? Put it to us.
