TagAcam frequently asked questions


What is TagAcam?

TagAcam gives real time mobile and fixed speed trap alerts on your Smartphone. Add the SmartButton to legally, safely & easily share and verify alerts.

Is it legal?

Yes, of course. TagAcam is fully legal in all the countries where we promote, including the UK, USA, Australia and most of Europe. TagAcam uses the same technology as traditional sat nav products. But it is also the first app that allows you to engage with other riders in real time, using our new SmartButton connected wirelessly to the TagAcam app. You simply attach the SmartButton to the handlebars of your bike or the dashboard of your vehicle and click it to confirm and share new and existing live speed traps. You don’t need to touch your phone at any time, so you are not breaking any laws.

Some countries restrict the use of any type of device that lets you know where speed cameras are. These include Sat Nav units (Tom Tom / Garmin / etc), GPS speed camera locators, smartphone apps, radar detectors and laser jammers.

France: You are allowed to be notified of a dangerous area, but not of an exact camera location.

Germany: It is not permitted to use any device that will tell you where speed cameras are. But enforcement varies from region to region.

Switzerland, Turkey, Cyprus, Macedonia: It is not permitted to use any device that will tell you where speed cameras are.

Can I use TagAcam in a car?

Yes! We hope that you do.

You can use TagAcam in any vehicle. And it’s easy to transfer the SmartButton if you are the driver, or you can just tap the phone screen if you are a passenger.

Trinity database

What is the Trinity Database?

We’ve been developing our Trinity database since 2003 to give you instant access to current speed and red light camera alerts for many countries around the world.  Our global database has been verified by the Trinity team, who also communicate directly with agencies such as local police departments and local governments.  We do not rely on 3rd party information and every user reported location is subsequently verified by ourselves.

Our Trinity database already includes static speed and red light cameras, point to point speed cameras, safety locations, stored mobile sites, school and park zones and is used in our own Cheetah products and licensed to a number of other manufacturers for use in their products.

TagAcam allows you to comprehensively tailor the Trinity database alerts to suit your driving style. You are in complete control over which type of alerts to hear and how they sound. By individually turning on and off each possible tone and voice component and setting custom warning distances for each of the 14 different types of alert, you will only hear what you want to.

Not only does TagAcam download and store the Trinity database to your Smartphone, it also lets you to share live mobile speed traps in real time using the innovative new SmartButton that can mount anywhere.

Who are Cheetah?

Cheetah have been been making award winning speed and red light camera detectors since 2003. You can read more about us and our history here.

Which countries does the Trinity database cover?

Please visit our coverage page for details of which countries are included in the Trinity database of speed cameras, red light cameras and safety locations.

What do you do with all the clicks?

Clicks remain anonymous, but we have some very clever people who know what to do with all the clicks :-)

Does there have to be a large number of people using the app to make it worthwhile?

There already is. A major benefit of using TagAcam is that you are automatically entitled to Trinity Membership. The Trinity database already covers fixed cameras, mobile sites and safety locations around the world.

Any new clicks are shared almost instantly so you’ll get the benefit even if you’re just travelling alone or in a small group. And the best roads are always popular, so it doesn’t take much to build up a picture of what’s happening.  

But most importantly, we have you and the ever growing TagAcam community who love to Click and Share. Of course every single additional contributor enhances TagAcam for everyone, so be sure to tell your friends.

How does TagAcam work?

How will I get the alerts?

TagAcam uses your smartphone to give its live mobile speed trap and fixed camera alerts.

The best way to get these alerts on your bike is to hear them through a Bluetooth headset or using earphones.  Of course you can see the alerts on your phone too, but we feel it’s safer to keep your eyes focused on the road. 

Drivers can see and hear alerts on your Smartphone. You can verify alerts ‘hands free’ using our SmartButton or passengers can simply tag by tapping the screen.

I wear earplugs when I’m on my motorbike so how would I hear audio alerts?

There’s a whole range of earplugs that can also connect directly to your phone so you’ll be able to wear earplugs and still hear alerts.

I don’t want phone calls when I’m out on my bike. Can I switch them off?

You can simply set your ringtone volume to zero so you won’t be disturbed by phone calls if you don’t want them.  

You will still hear TagAcam alerts as they are controlled separately through your media volume setting.

How far in advance will I get a warning?

You can set different custom alert distances for each type of speed trap. For live mobile speed traps, the warning distance can be set between 300 and 2000 metres.

How do I know TagAcam is running when I’m riding?

You can easily switch on a monitoring tone and choose how often you’d like it to beep  to let you know TagAcam is running.

What if someone incorrectly tags a location as a speed trap?

If you think someone has incorrectly tagged a location as a speed trap, you can hold the SmartButton to request removal.  If you just want to adjust the exact camera location a little, you can double click at the correct spot.

The Trinity database team verify every fixed location and add micro details to enhance the alert if required. They ensure the integrity of the data and will educate against continued false reporting where necessary.

How will I know when a live mobile trap was last seen?

Live mobile traps have 4 levels of alert intensity that reduce over time.

  • 1 – less than 5 minutes ago
  • 2 – 5 to 30 minutes ago
  • 3 – 30 minutes to an hour ago
  • 4 – more than 1 hour ago.

You can select which older sightings you’d like to see within the settings menu. 

Frequently reported traps transfer to the main Trinity database and are classified as “stored mobile sites”. You can choose to switch these alerts off.

I already use my Bluetooth headset for the phone/music and/or navigation so how will I hear the TagAcam alerts?

If you have already paired your phone with your headset, you don’t have to do anything else. You’ll hear TagAcam alerts alongside your calls, navigation instructions or music.

If you haven’t yet paired your phone with your Bluetooth headset, it’s easy to do. Please refer to the instructions that were supplied with your headset.

Or you can just plug in a set of earphones and you’re all set.

Is it possible to set a personal speed alert?

Yes, you can set a Preset speed reminder. This will alert you if you exceed the selected speed. Many customers use this feature if their vehicle is limited to a particular maximum speed. 

Will I constantly hear alerts while riding?

TagAcam alerts are fully customisable.  You will only hear what you want to hear.  
And we also have an auto mute facility, which can reduce the alert volume after a few seconds so that you can keep concentrating on the road.

What if I forget to switch on TagAcam?

TagAcam includes an option to switch on automatically when you start to ride and switch off again when you end your ride. 

Or you can choose to switch on manually by clicking the SmartButton or tapping your screen at any time.

How will I know if my click worked?

You’ll hear a confirmation tone each time you press the SmartButton and each type of click has its own tone.

How does the SmartButton work?

How do I alert other riders if I see a mobile speed trap?

We’ve got a tiny new SmartButton that connects wirelessly with the TagAcam app, so you can now engage with your community to verify speed trap alerts and confirm what’s on the road ahead. Simply attach it to your handlebars, helmet or dashboard in the car, then…

Click once to let the community know a live mobile trap is still active

Double click to confirm a fixed camera alert

Hold to let everyone know the threat has gone.

How does the SmartButton communicate with TagAcam?

The SmartButton uses low power Bluetooth to communicate with your phone. 

It’s clever enough to work alongside any other Bluetooth devices you already use and it won’t restrict you from pairing new Bluetooth devices in the future.

Can I report a live mobile trap on the opposite side of the road?

Yes! Just click the SmartButton once, wait a few seconds, then click again.

How long does the SmartButton battery last?

The SmartButton battery will last for more than a year of normal use.  It uses an inexpensive CR2016 battery that’s quick and easy to change.  The SmartButton will flash periodically to warn when the battery needs to be replaced.

Do I need to switch the SmartButton on and off?

No – it just works!  The SmartButton uses low power Bluetooth and is always on and ready to click.

Can I move the SmartButton between bikes and other vehicles?

Yes! It’s so easy to move and use the SmartButton wherever you are going or however you are travelling.  Just take it with you and stick it in or on the new vehicle. If it gets dirty, just clean the back of the SmartButton with water to make it stick like new again.

Why would I need TagAcam?

I don’t want any distractions when I’m out on my bike so why would I want to hear alerts?

Worrying about live mobile and fixed speed camera sites are distractions in themselves. With the TagAcam app you can relax knowing you’ll hear about an alert before it takes away from the pleasure of your journey.

I don’t speed so why would TagAcam be useful to me?

Downloading TagAcam means you are kept informed of what’s coming up on your journey whether it’s a live mobile trap, speed camera, red light camera, point to point speed camera, safety location or school zone. Most people have found themselves drifting over the speed limit at some point when they’re driving – TagAcam gives you a heads up when there’s a potential threat so you can keep safe and legal.

TagAcam alerts are direction specific, so you’ll know just what to look out for, such as an intersection with a problem of red light running in another direction. 

You also have the option to let your group know what’s happening on the road ahead just by clicking our SmartButton.

How does it help me if I’m the first one at the live mobile trap site?

We use the Trinity database, which stores the locations of frequently used mobile sites.  Live mobile traps on popular routes will be well covered by earlier riders, but if you are first on the scene you can Click, Share and feel good knowing you’ve helped out the wider community.

We also monitor our database carefully, so if we’re getting the same mobile trap verified over a period of time it will become a stored mobile site as part of our Trinity database.

I’ve already got sat nav/Tom Tom/Waze so why would I want this?

TagAcam is unique. Not only does it give you more detailed speed camera alerts than any other app, it is also the first app where you can legally let your group know in real time what’s happening on the road ahead. All with just the click of our SmartButton.

  • Each click you share lets your community know what’s coming up.
  • Each click someone else shares gives you an alert before a live mobile trap.
  • Each click helps avoid speeding tickets!

Each and every click helps to create the best possible database of live mobile and fixed speed cameras for you.


You can use your sat nav or Waze at the same time if you like, but you can’t report traps on them when you are riding. TagAcam finally allows you to engage with the rest of the biking community in real time to share and verify speed traps. 

What about phone signal and data use?

What happens if I go through a tunnel and lose GPS reception?

If you click the SmartButton in a tunnel after losing GPS and phone signal, TagAcam will buffer and send this when you exit the tunnel. The TagAcam community will then be warned at the start of the tunnel.  

What happens if I lose phone signal?

If your phone signal drops, TagAcam will buffer any clicks and they will be sent when the phone signal returns. And you will still be alerted to any live traps downloaded prior to signal loss.  

The Trinity database of fixed locations is stored on your phone and doesn’t require an active signal to alert you to fixed cameras, stored mobile sites and safety locations.

How much data allowance does TagAcam use?

To minimise data transfer on the move, TagAcam pre-stores all the fixed camera alerts on your phone and only updates the nearby live mobile alerts as you ride. 

You can choose to update the fixed camera database automatically when a new database is available. Or you can wait until you have a WiFi connection.

Nearby live mobile traps are continually refreshed to your phone during your ride, and you can adjust this frequency if you wish. The actual amount of data allowance used will depend on this frequency and the number of live mobile traps in your vicinity.

TagAcam only downloads live mobile traps near to you when you are travelling, to minimise data usage. 1 Mb of data would equate to around 20,000 live mobile trap traps, which would take a very long time to encounter!
