Aren't these things just for people who run red lights or speed? Why do I need one?
Camera detectors are not niche products designed for speeders or red light runners. Sure, they will help you avoid a ticket but they are also every-day road safety systems for all responsible drivers that help to improve situational awareness.

Nobody can fully concentrate for 100% of the time. All of us have occasional lapses which could easily result in an accident or a fine and licence endorsements. Collisions, fines or penalty points can all result in increased car insurance premiums to say nothing of the implications for personal safety.

80% of auto accidents involve driver distraction. (Virginia Tech Study, 2006) When speed cameras are placed in accident blackpots, using a camera detector makes sure that you are not distracted at a vital time, i.e. when you're driving along that stretch of road that has a bad history of accidents. Camera detectors remind you to be paying attention when you need it most.

Almost 60% of red-light running in the USA is caused by drivers not paying attention or becoming confused. (Federal Highway Administration Statistics). A camera detector makes sure you won't accidentally run a light yourself by drawing your attention in advance to the dangerous junction approaching. It gives you time to think, concentrate and plan ahead safely.

33% of red-light running is intentional. (Federal Highway Administration Statistics). Red light cameras are placed where they are most likely to catch red light runners so being reminded to pay extra attention at these junctions will not only help you avoid a fine yourself... it may even help you avoid a reckless driver!

It’s been well documented that rear end collisions can increase at red light camera locations, caused by drivers panic breaking at yellow lights to avoid a ticket. Being more aware of these camera intersections in advance makes you better prepared to avoid that type of accident.

To make red light cameras financially viable most cities have to enforce right turn on red, so even if you proceed through a light at 2 mph, a perfectly safe driving practice that you may have been doing for more than 30 years, it can suddenly lead to an unjust ticket and you being branded a red light runner. Tickets are expensive and in some states like California and Arizona can lead to points on your license that increase you car insurance for years to come.

Finally, the more accurate GPS speedometer, combined with advisory speed limit announcements during camera alerts and the optional Speed Reminder features, means that a GPS camera detector will help you to become much more aware of your speed at all times, which can only have positive safety implications for all.

Is the C50 legal?

Most governments recognize the fact that GPS Detectors give drivers advance awareness of the accident areas where cameras are located and act as an electronic extension of the existing road signage. They are genuine road safety aids which can help reduce casualty figures. Police view these devices as useful road safety tools because they help all drivers, particularly when they are in unfamiliar areas, to have the same level of knowledge about accident areas and camera locations as a reasonably informed local driver.

 

USA and Canada

Yes – GPS camera location is legal in every state in the USA and Canada.

 

United Kingdom 

Yes – GPS camera location is legal in the United Kingdom.

The UK Government have stated that using GPS to warn of speed camera locations is legal.
"The Government will not be prohibiting those devices that rely on Global Positioning System (GPS) technology to warn drivers of published camera sites or posted speed limits, as these compliment the Government's policy to ensure that camera sites are visible and conspicuous to drivers, and so help deter excessive and inappropriate speeds on the roads."


Radar and laser based detectors and jammers operate differently to GPS based camera warning systems. There is draft legislation in place in the UK that would ban the use of detectors and jammers, but this legislation is not yet enacted.

 

Germany

There is currently no legislation banning the use of GPS to warn of speed camera locations in Germany, but there has not been any legal precedent to explicitly confirm this position.

Radar and laser based detectors and jammers operate differently to GPS based camera warning systems. There is legislation in place in Germany that bans the use of detectors and jammers.

 

France

All types of camera warning systems are banned in France.

 

Switzerland 

All types of camera warning systems are banned in Switzerland.

 

Liechtenstein 

All types of camera warning systems are banned in Liechtenstein.

 

Other countries

If a country is not listed above we do not currently have any information about specific legislation governing the use of speed camera warning systems for that country.


Please note: The driver of a vehicle will most likely be held accountable under local laws for the use of any camera warning systems in or on a vehicle.

What's the difference between the C50 available in the USA/Europe and the C50i Hebrew language version available in Israel?

The C50 GPS camera detector is available in its standard English language format in many countries around the world.

We have partnered with a number of dedicated and highly experienced experts in selected countries, and successfully combined decades of specialised local knowledge with our technical expertise to create uniquely tailored versions of the C50 for local consumers. These optimised C50 versions are only available from local suppliers. They are not available from other sources.

In Israel, the optimised C50 is called the C50i. Visit www.speedcheetah.co.il for the C50i Hebrew summary of benefits. Purchasing the C50i locally means that there are no additional import taxes.

 

C50i database updates:
The C50i is supplied inclusive of full Platinum database membership. This gives lifetime, global database updates at no extra cost.

C50i Hebrew voice alerts:
The C50i speaks in Hebrew, recorded by one of the top narrators in Israel. It's not possible for any other C50 versions to speak Hebrew.

C50i database structure:
In order to provide an optimised solution for the demands of the Israeli driver, Cheetah Israel and Cheetah HQ have worked together to tailor the alerts that Israeli drivers want to hear. The standard C50 and the Hebrew speaking C50i units will alert to active speed cameras in the same way, but can give different styles and types of safety alerts.

C50i exclusive firmware:
The C50i firmware developed by the Cheetah software team, in conjunction with Cheetah Israel, is yet another enhancement for local C50i Israeli drivers. The C50i firmware allows you to choose between 4 tailored driving modes, instead of the standard 3 modes. Among the C50i 4 driving modes is Fspd, which is Full-speed mode. In Fspd mode, the C50i will alert only to fixed speed cameras and mobile sites - it will not alert to any other safety alert, red-light camera, bends etc.

C50i service and warranty:
The Cheetah C50i includes a full 2 year hardware warranty. During that period, a unit will be repaired or replaced if needed in order to maintain the Cheetah driving experience by the original purchaser.

Service points are located all over Israel that offer accessories, installations and hands on service if needed, but most support and service requirements can be easily provided via the online support form at www.speedcheetah.co.il or the active online forum community.

IMPORTANT SERVICE NOTE: Because the standard C50 has a different firmware version to the C50i, service for standard C50 units can’t be provided by Cheetah within Israel at any Israeli service points. Requests for service for standard C50 units should be directed to the shop where originally purchased, outside Israel.

What's the difference between the C50 and the C100 or the GPSmirror?
The C50 is a stand-alone camera detector. It does not interface with radar detectors or laser jammers like the C100 or GPSmirror. The C50 uses the Trinity 2.0 Enhanced Database to provide 65 voice alerts in a US accent. C100 and GPSmirror use the standard Trinity Database. For a more information, please see the Comparison Table.

I am not getting satellite lock / satellite lock keeps dropping / speed jumps up and down. Is there a problem with my windshield?
If the GPS signal is partially blocked by heavy trees, steep walls or a tunnel, the speed display might look slightly erratic for a short time until you clear the obstruction.

If you have clear line of sight to the sky above and still experience this problem, it’s likely that you have an “Athermic” windshield. “Athermic” glass (sometimes called comfort glass, solar reflective or UV reflective) can prevent satellite signals getting through it to reach the internal GPS antenna which results in either no speed being displayed, intermittent or erratic speeds, or even an extreme amount of time to achieve a satellite lock. This glass also greatly reduces the performance of radar detectors because it cuts down the amount of radar signals entering the vehicle.

There are a three easy ways to check your windshield to see if it is the cause of the problem.

1. If you have polarized sunglasses, look at the windshield through them to see if it looks purple.

2. In a stationary vehicle, hold your Cheetah GPS detector out of the window to see if satellite lock is faster.

3. Click here for the Athermic Windshields – Vehicle List. This list is not exhaustive but is correct to the best our knowledge at the time of writing.

If your windshield is Athermic, you can purchase a remote extension antenna from Cheetah to collect GPS signals through the rear window or from the outside of the vehicle.

I did not get an alert at a camera intersection. Is there something wrong?
Check the red light camera guide to make sure you are not mistaking a traffic flow camera for a red light camera system. Perform a database update – new cameras are added on a daily basis.

Press the [SELECT] button to select User Mode 1 – All cameras, mobile sites and safety alerts and re-check the intersection for an alert. Cities will usually only install cameras to cover 1 or 2 directions (called approaches) at an intersection, but often put up warning signs are on all 4 approaches to make drivers think that all directions are enforced. If you run the C50 in User Modes 2 or 3, it will only alert for the approaches that are actually being covered and will stay silent on the other non-enforced approaches. Selecting User Mode 1 will turn on the alerts for the non-enforced approaches and you should hear a “Photo-enforced intersection” alert to confirm the location is in the database. If you still get no alert in User Mode 1, please report the location to us.

I've found a new camera location that is not in the database yet. How do I report it?
You should report any new camera sightings here. Alternatively you can send an email to with as much information as you can. Our database team will check out your report and add it to the Trinity™ database.

You can always store a new camera as a personal location, which can be deleted once the camera has been added to the central Trinity database.

How do I store/delete Personal Locations?
To store up to 100 personal locations
Press the [ENTER] button to store a marked location. The number of the memory position where those coordinates are saved is shown on the display screen.

Personal alerts are directional so will only alert when you are traveling back to that location from the same direction.

ADD IN ALERT DISTANCE and advice on when to store mobile traps

To delete an individual personal location
Sometime you may want to delete a particular personal alert; for example, if you store one in your driveway. Press the [ENTER] button briefly during a personal alert, when you hear the “Marked location ahead” message. You will hear a voice announcement say “Location deleted” and the screen will show DELE.

To delete all your stored personal locations
Press and hold down the [ENTER] button for 5 seconds until you hear the “Location deleted” message and the display reads ALDE. (All deleted).

How do I change the time on the clock?
The default setting for the clock is off. Only Members can switch on the clock feature using the Cheetah User Software Tool. You can easily adjust the clock setting by changing the time zone from the drop down menu. Pacific = -8, Mountain = -7, Central = -6, Eastern = -5, etc.

Daylight Savings Time (DLST) / Summer Time Adjust: Please set your time zone and then select if Summer Time is ON or OFF, then Save.

If you have an older C50 Software Tool without Summer Time adjust, simply change your time zone: if your time zone is -7, please set the clock to -6 for DLST, then back to -7 when necessary.

Once you enable the clock feature, it cannot be switched off again.

Why is the speed display on my C50 different to my car's speedometer?
All car manufacturers, by law, have to calibrate their speedometers to make sure that the vehicle is never actually traveling faster than is indicated on the display. This means that, in practice, car speedos will always slightly overestimate your true speed for safety reasons. This variance can change from model to model and maker to maker. Your car’s speedo can also become slightly inaccurate if you change the size of your wheels or tires.

At a constant speed the GPS speedo in your C50 is more accurate than the one in your car because GPS speed readings are calculated from an independent source.

During acceleration and deceleration, your car speedo will be more accurate that the GPS speedo. GPS receivers only check their position once a second so will always have a slight lag before the reading is updated to show your new speed. When you reach a steady speed, the GPS speedo returns to being the more accurate measure.

Can I move my C50 between vehicles?
Yes, the C50 has been designed to be easily transferable between vehicles. If you require an extra power cable, magnetic mount or remote GPS antenna to fit in a second vehicle, you can purchase these items separately.

Back to top

 

 

 

 

 

Can I hardwire the C50?
Yes. You can purchase a hard-wire power supply. You cannot hard-wire the C50 directly into your car because it is a 5 Volt product, not 12 Volts. However you can hardwire the optional power supply and simply plug in the C50’s own power cord to that extra socket. If you are unsure how to do this then consult a professional automotive electrician.

How do I adjust or switch off the Speed Reminders?
The Speed Reminder feature is very useful if you want to be reminded to slow down whenever you accidentally drift over the speed limit, for example on a freeway / motorway.

You can store up to 5 speed reminders at the exact speed you want, in increments of 1 mph. When you are driving along, just press both buttons at the same time, [ENTER] and [SELECT], to set a speed reminder. Whenever you accelerate past the stored speed reminder setting you will hear a chime and the display will show your setting.

To delete a speed reminder, simply press both buttons again, immediately after you hear the chime for reaching that speed.

You can also set, change or remove any of the speed reminders using the user software tool.

My C50 is not powering up? How can I check if it is broken?
Check if the C50 powers up when you connect the USB download cable to a computer. this will tell you if the C50 detector is working correctly or not. Next, check that the power cord is correctly inserted into the power socket on both the C50 and the vehicle power adapter. Then check that the power adapter is fully inserted into your vehicle’s power socket. You can also check that the power socket is clean and working correctly by powering up another device like a cell phone. Finally, check the fuse in the Cheetah vehicle power adapter (behind the silver tip) by unscrewing the end of the Cheetah plug.

I want to use my C50 as a GPS antenna plugged into my laptop. What baud rate should I set?

If you have a C50 unit with a serial number equal to or lower than 5002624, you should select a baud rate of 115200.

Unfortunately, the NMEA output feature is not available on C50 units with serial numbers greater than or equal to 5002625.

Back to top

 

 

 

 

 

Is the C50 like a radar detector?
No. The C50 uses completely different technology to a radar detector. The C50 uses GPS location to check its position against an onboard database of fixed safety camera locations, accident blackspots and common mobile sites. When you are approaching any of these stored locations, the C50 provides a warning.

Radar detectors do not alert to most speed and red light cameras because the cameras use sensors buried in the ground, so there are no radar signals to be detected in the first place. Radar detectors also give hundreds of false alarms for other radar sources like automatic door sensors. The C50 does not false alarm for these sources – it only alerts to locations that are stored in its memory.

Back to top

 

 

 

 

 

Can I link up a radar detector or laser jammer to the C50?
No. The C50 is a stand-alone GPS camera detector only. If you want to suppress false alarms on a radar detector, or wirelessly integrate with a laser jammer, then you should purchase the C100 or GPSmirror models instead.

Why does Cheetah charge for database updates on the C50, but it is included for free in the C100 and GPSmirror?
Common sense will tell you that it’s impossible to provide a high quality database for free. At Cheetah, we’ve always charged for the database update service, it’s just that with the GPSmirror and C100, the cost of a lifetime subscription to the update service was built into the initial purchase price of the product.

Splitting out the database update service for the C50 is the fairest way of keeping the cost down for drivers in states where the camera numbers are static and they don’t need an update service. However, even with the cost of Membership Packages included, the total cost of ownership for the C50 represents the best value for money on the market over 3 and 5 years. Plus with the Platinum Membership, we include 3 years warranty cover (1 year manufacturer’s warranty + 2 years extended warranty).
