Best legal speed camera detector (WA)?

Hi all,

Just wondering what's the best legal speed camera detector? I'm in WA by the way. I presume it's still laser technology? or is it lidar?

Mainly wanna detect speed detector on an under-cover police car, and mobile speed camera. What band are they using these days?

Please don't get into a debate of speeding…that's for another day lol

      They show where FIXED cameras are

      • Waze app shows where mobile ones and police locations are too. Extremely accurate in NSW even though crowd-data. It's also a really good navigation app based on Google Maps.

      • tomtom also shows known mobile speed camera sites


          tomtom also shows known mobile speed camera sites

          Tomtom showing speed camera locations is one thing … Crowd sourcing police locations (eg RBT) is potentially soooo much more harmful. If drunk drivers and drugged up drivers know where RBT is, they will just take alternate routes to avoid. I know a habitual offender of drunk driving/riding, he used all the back street to get around drunk, then when he had an accident on his motorcycle drunk, he asked everyone that stopped to hello not to call police or ambos.
          Someone like this, needs to be taken off the road, and giving location of police just helps him avoid them

  • pretty sure they're all using laser these days, which means when you'll be measured before you get a warning

    • Yep, I have an ex-police laser radar speed gun and have lasered cars speeds at about 1km away and the read out is virtually instantaneous. If the radar detector alarm goes off for laser, it's usually already too late.

      The other thing is that a lot of mobile roadside radar sites have the radar facing away from the oncoming traffic and pick you up as you are passing it, not always as you are approaching it.

      There is also new technology that the mobile cameras don't require any radar and are calibrated to work out your speed from measuring how far you travelled across frames in the video.

      So, the chance that these speed traps that OP is hoping for that are using K-Band radar and facing it directly at their car, is pretty much zero these days… But it is WA. I wouldn't be surprised if they didn't have any up to date technology…

    • Back in the olden days (say late 1990's) the laser signal had to bounce 2 or 3 x back and forth between the car and the gun, if the measurement of speed differed the result was an error on the gun, this allowed detectors back in the day to alert drivers to suddenly brake and cause error on the gun. Laser spill from guns targeting motorists ahead also set off the detectors. Does anyone know if this is still the case?

        Those radio waves were moving at the speed of light. You needed quick reaction times in the 90s.

      • I doubt a human could react fast enough to a detector to force an error on a laser gun, ignoring processing time a laser could bounce between a radar and a vehicle tens of thousands of times in the average humans reaction time, let alone actually moving to the break pedal and slowing the vehicle you'd be looking at hundreds of thousands of potential bounces. Laser's are also pinpoint accurate, there would be no spill. Are you thinking of radar speed detection?

        • So laser are K band commonly detected?

        • I doubt a human could react fast enough to a detector to force an error on a laser gun

          I agree, they couldn't. I have a laser type speed gun and if I point and shoot it at a car, the speed reading is almost instantaneous. Some of the older "radar" guns used to have a laser sight on them to assist with aiming. Those types only used the laser for aiming, not for reading the speed.

          Laser's are also pinpoint accurate, there would be no spill.

          There is still spill on laser, but it is way more confined. I think lasers are about 3m spill at 1000m range. For K and Ka band radar, the spill at 1000m could be anywhere up to 200m wide. So laser spill would still only be about the width of a car at 1000m, where as radar is about 2 football fields at the same distance.

    They are always speeding in WA to make up for the time difference to the rest of the Australian population.

    • This will become more of a problem as WA people abandon horse and cart…

    • I'll be sure to remember to put that as my statement when police officer asks me why i sped next time.. 😂

    Cars already come with these built into them. It’s usually mounted in the dash in front of the driver. Super easy to use as well. Comes on automatically as the car starts moving.

    How it works is that there are these special signs mounted near roads. Light bounces off these signs and back to receivers mounted in the drivers head. The drivers onboard control unit then uses the dash mounted device to check that the reading from the sign is either greater than or equal to the display shown on the dash. If the dash read out exceeds the reading from the sign, and if the drivers onboard control unit isn’t damaged, it will send a message to the right foot to make adjustments. It’s an amazing system and cheaper to use than you might think.

    Just make sure that the sensors are open and functional and that the drivers control unit is switched on and not damaged. So many drivers get in their car and don’t switch on their control units or open their sensors… and then we have to put up with their stories here.

    From OP's other post about "speeding"

    Go easy on me guys, learnt my lesson

    And here they are asking about how they can evade speed detection rather than just abiding by the road rules like everyone else.

    • 'Everyone else' do not abide by the road rules. Just did a trip up the coast yesterday and I swear every second car is speeding or tailgating or breaking some other road rule. And people go on about cyclists and what not.

      The government themselves publish locations of speed and redlight cameras helping drivers avoid (evade) tickets.

    • Appears it was night time and raining, a stretch of road where they've clearly deliberately got a reduced speed section of road, going 30km/h over the limit. Says they learnt their lesson, but makes excuses in the comments, including it being in part due to a lack of concentration while driving.

  • You could save your money and potentially lives by obeying the law in the first place. That will save on buying the tech as well. Unless of course, you think you are above the law?

    • I'm talking fine of 5-10 over here.. Get off your high horse will ya.. Speed were never real kill factor, if yes, German autobahn will be full of casualty

      • Did you just compare the autobahn with the roads in WA?!

        • I find autobahns to be narrower than most Australian roads, but their road surface is generally superior than most Australian roads.

      • There is currently a wide public discussion in German media to get rid of the unlimited speed sections on the autobahn, because the speed does actually contribute quite significantly to casualties (link to German news article use Google translate)

      • Speeding is a victimless crime. When you expeed the limit by 2% nobody suddenly dies. It's all about the nanny state meddling in evry aspect of peoples' lives.

        • Well, it’s a victimless crime, until that speeding a-hole loses control and slams their car into oncoming traffic or around a tree… you know, up until then it’s totally victimless…

  • I have never understood why people see undercover cops and your "Flash for cash" vans as a government cash grab.
    Don't speed and they are irrelevant and will not impact you.

    • I tried to explain this to someone at school the other day who was going off about a parking ticket they received and was ranting about it being "revenue raising". I tried to explain to them that it isn't. Lifting her land rates and water rates is "revenue raising". You don't have a choice but to pay those. Parking fines (and other traffic fines) are totally optional. So, I described them more as "tolls". It's a user pays service. If you want to park closer, or get there faster, be prepared for the toll that you may have to pay.

      • The points system is appropriate. Too many bad decisions accumulates too many points and you lose your license for a while. That makes sense.
        $200 for 8 km/h over is indeed revenue raising.

    • Wait till you get a fine for 5 over… I called that revenue raising..

      • Are you over? Is it optional? It’s not “rEvEnUE rAiSiNg” if you opted to speed.

        Added to this is the error factor of most modern speedos. They could read anywhere up to 10% faster than when you are doing. So, if you get booked for 5km/h, chances are your speedo was reading up to 15km/h faster than the speed limit. Added to this, when fines are issued, there is a error margin also subtracted to your alleged speed…

        So, I put it to you, factoring this error in speedo reading and the leeway the police give on tickets, most people know they are speeding. 105km/h ticket, + 3km/h leeway, plus 10km/h error, this puts the speedo read out at 115~118km/h. The driver would 100% know they were speeding at being booked @ 5km/h over, so it isn’t about revenue as it is about breaking the road rules and paying the toll.

        Don’t want to pay the toll? Don’t use the fast lane. Totally optional.

      • Both hubby and I have been driving for 15+ years and never had a fine. So there is a choice factor in it; we just follow the signs, even if we think they're stupid.

        If you want to go fast, look at racing or even just track open days you can do around Perth. There's heaps of different ways you can give it a go and try out different forms to see what you like. Even though it's expensive, racing is addictive and makes general road driving seem boring as, especially considering how rubbish the roads are. You can participate ad hoc, go regular, use their vehicles, get your own, whatever suits you, there's a lot of flexibility.

    • You've clearly never been to parts of the country where speed limits are dropped from 100kmph to 60kmph or silly signs put up.

      We have a 3km stretch changed from 100kmph to 60kmph because someone had a near fatal crash. The driver was on ice. It is a country road where the only hazard was drugs. The rest of the road to the next town (approximately 20km) is still 100kmph but drugs apparently don't work there.

      The cops are usually camped out at the 60 spot because catching someone doing 65 on 60 is more dangerous than someone doing 105 on 100 on the same road conditions.

      I'm not saying it's all a cash grab but it would be foolish to not acknowledge that at least some of it is blatantly so.

      (Actually, I think there was 2-3 crashes over the last few years. All were on ice. It is that kinda town.)

    • Because the places where the cameras and cops hide out are usually not known as danger areas. Plenty of camera locations in Perth are along straight sections of road where no crashes have been seen ever.

      Sure, don't speed, don't get a fine, but if it were about safety, then these cameras would be all over the black zones, and advertised up front to SLOW people down through the dangerous areas, not catch people out.

  • Super illegal and not recommended. But there are laser jammer devices available which do work. The trick (I'm told) is you have to turn them off before the police (in the case of a handheld gun) realise what's going on, and so by that time you've slowed down and they get a lock of your current (legal) speed. IF it's automatically operated as in a camera system, it just doesn't get a lock and ignores it.

    No radar jammers unfortunately unless you're a fighter jet. But the Valentine 1 detector picks up speed cameras which are radar based in some cases KILOMETERS away.

    You won't need one if you don't speed then again over 90% of drivers on the road are over the speed limit in any given moment.

  • Ok, put this topic on track, looking at Uniden R3 DSP, was told it's the best around. Any idea it will work in WA speed detection technology?

  • The Uniden R3 Extreme Long Range Radar detector seems to be best one out there atm

  • you should all be more worried about the new cameras detecting drivers using mobiles

  • Waze -

    Every speed camera is mapped. You can also report mobile speed camera's/police.

    Haven't had a speeding ticket for 5+ years because of it.

    • Useless in WA.

      Used it on a trip to sydney once and every cop was listed (and there were a lot).

      WA, not so much.

  • IMO Valentine One

  • Valentine One. Used it back in the days when it was legal in QLD and worked like a charm, but too many false warnings some times.

  • How about an active laser jammer rather than a detector?

  • Valentine 1

  • As some have said before, if they're using laser it's usually too late by the time you detect it. K band is still used on country police vehicles, often mounted to the roof or dash for detection whilst moving. These are easy to detect with all radar detectors with reasonable distance.

    For those outside WA, we're lucky enough that WAPOL publish speed camera locations in advance to the public:

    Radar detectors + published speed camera locations = WA FTW!

  • As OP said "No lectures about speeding" (paraphrasing). I'm assuming everyone in this discussion is just curious about the technology because I'm so not prepared to invest time in this discussion I won't even bother pulling out the calculator.

    Time Saved by Speeding:
    Let's presume I have to travel 10 kms in a 60 zone but I'm prepared to risk doing 69 km/h (+15%). If I can instantaneously hit 60 km/h at the start of the journey & can instantaneously stop at the end of the 10 km journey it will take me exactly 10 minutes (60 km per 60 minutes). Traveling 15% faster will save me 90 seconds. Let's now take into consideration the time to get up to speed & to decelerate, traffic conditions, cornering etc. I might save myself 60 seconds.

    I hate the speed limits in Australia & I hate the revenue raising from speeding fines but unless you are a serious risk taker & traveling a long distance there seems to be little point in speeding let alone this discussion.

    I get up to the speed limit (by my GPS) & hit the cruise control button, it's a habit now & I don't even think about it. I have not had a speeding fine for 28 years. I've know over those 28 years I have sat for many minutes longer in the car than of I had reduced every drive by 15% but that is ok with me.

    • Couldn't agree more. In most cases they'll just get to the next set of lights a few seconds earlier.

      Tailgating is a more serious problem. Plenty of drivers just speed up to the next car and then sit on their tail. They could easily change lanes and go around if they really wanted to go faster, but instead they're actually playing follow the leader. So much for having visibility of the road ahead.
      Sometimes I will change lanes, so they can catch up to the car in front of me and sit on their tail.

      As for speeding itself, I think most people do it out of principle. If the government decided to increase speed limits 10 km/h (or whatever), then people would still drive a bit faster than the speed limit.

      Plus drivers are generally dumb, and can't drive to conditions or judge the speed required for corners. So much for applying the 85th percentile.

    • You must live in a city. On a long country drive a little bit faster will get you home significantly sooner.

  • Use the app name Waze then easy .

  • Valentine 1 and an array of switchable jammer/parking sensors.
