C150 speed and red light camera detector


The Cheetah C150 is the latest in our series of innovative and award winning GPS speed and red light camera detectors. It builds on the success of our C50, which was awarded the ‘Best Buy of 2014’ by Auto Express magazine. We believe the C150 coupled with our internationally acclaimed Trinity 2.0 database sets the new benchmark for consumer GPS speed and red light camera detectors.

Product Description

The C150 is designed to be as customisable as possible. Users can completely tailor each component of the audio output to their own requirements. One complete alert comprises an initial heads-up chime, a voice description of the type of alert, an additional explanatory description of the area if required, an overspeed alert and a final pass chime. Each constituent chime can be configured to meet the individual user’s expectations.

The C150’s impressive, uncluttered 64mm * 18mm LED display clearly shows all the vital driving and alert information you need. The digital speedo remains visible at all times and the handy clock and compass features keep you nicely informed. During an alert, the current speed flashes to highlight if you are over the speed limit and the clock switches to show a numeric distance countdown to the alert site. There is also an additional distance countdown progress bar to emphasise the alert site proximity.

We’ve been busy behind the scenes too. We’ve updated and improved our multi-point false alert filtering and also added a brand new layer of “effective distance” false alert filtering. But most importantly, we’ve greatly improved our intelligent multi directional alert ability and introduced a massive number of new alert descriptions to maximise on our unique Trinity 2.0 database with nano alerts.

With 1400 possible alert voice combinations, the C150 knows what to say and when to say it.

User comments

I purchased this when I read the spec. This is an magic little machine; just plug in in and it works, nicely concealed above the rear view mirror. As soon as I turn the alarm off on the car and have sat down in the driving seat it’s up and running and logged into satellites. Absolutely brilliant, I totally recommend it. Well done Cheetah.


I have used 5 different products now and silly as it sounds, this is the first new one to beat the old Origin B2.


What a fantastic unit you have put together. Not only does it look good, it works even better than it looks. Everything from the neat switch on top of the power plug and the huge number of user options, to the fact its display is visible even in sunlight. I have always had problems with other units seeing the display clearly when the sun is shining through the windscreen, but not with the C150.

Needless to say I am thrilled with your unit and long may you prosper.


You guys have outdone yourselves ………….. it’s a quantum leap over the C50 !

Installation was easy and everything performed as advertised. I especially liked the DARK mode feature.
