Questions
Does PrioSense listen in on the police?
No. Emergency service conversations are encrypted and PrioSense doesn't try to decode them. It only measures how strong the radio signals nearby are, just like your phone can see how many bars of Wi-Fi there are without knowing what the neighbours are streaming.
Is it legal in the Netherlands?
Yes. PrioSense is a passive receiver: it transmits nothing, interferes with nothing and decodes nothing. It only measures how strong the signals nearby are. Taking it abroad? Check the rules of that country.
Does it know whether it's the police, an ambulance or the fire brigade?
No. It only sees that there is a strong signal in the TETRA band and how strong it is. Usually that's an emergency vehicle nearby, but it can't tell which one. For making way, that doesn't matter.
Does PrioSense recognise the signals of a police radio?
No. It doesn't recognise signals, rhythms or codes. It only measures how strong the radio traffic in the band is: the stronger, the higher the bars. That's also why it can react to other transmitters in that band.
Does it also work for vehicles without blue lights or a siren?
Often, yes. Vehicles that aren't on an urgent call still have their radios on. If there's no strong signal in the band nearby, PrioSense sees nothing.
How far ahead does it see?
In our own tests it noticed emergency services at about 300 to 500 metres in town, and up to about 1.5 kilometres on the motorway. Buildings weaken the signal, so the range is shorter in town. It reaches further ahead than behind.
Will I get lots of false alerts?
Channels that are active for a very long time, such as a fixed transmitter, are ignored automatically. In City mode it's less sensitive, so you don't keep getting a beep near a police station.
Do I need a subscription, app or internet?
No. You pay once and it works on its own, without a phone or internet.
How is it different from Target Blu Eye?
Both warn you about nearby emergency vehicles. PrioSense costs €399 one-off and you fit it yourself in a minute; Target Blu Eye costs around €1,250 to €1,490 and is often fitted by an installer. See the comparison.
Which countries does it work in?
In countries where the emergency services use TETRA. In the Netherlands this is called C2000. The same system is used in Belgium, Germany, Austria, the United Kingdom, Denmark, Sweden, Norway and Finland, among others. In France and Switzerland the emergency services use a different system, so PrioSense doesn't work there.
