Future me here 👋. Man did I ramble in this video! So I broke it up into sections so you can jump to the parts you may be more interested in. Thanks everyone! Maybe I’ll do an update soon with the new laser.

For anyone wondering why he said their patrol vehicles are tested for their speedometer accuracy & that their speedometers are accurate; almost all cars' speedometers show a higher speed compared to how fast you're actually travelling. That's why you should never say how fast you were driving to an officer, because you were probably going 3-4 mph less than what your car showed.

Thanks for sharing this! This was a very clear explanation of both radar and Lidar technology.

great video.. thanks... just wondering if taking videos through the window or something like rain or moving the radar unit while searching for speeders distorts the readings....

radar equipment looks so much fun to play with.

Nice video. Thank you very much for the video. Very informative and accurate. I was always interested in what the "tuning forks" for checking the radar transmitter physically look like used for checking.

Thanks for this video. I still have a question: don't I have to keep the testing fork in a box in order to keep it from corrosion and miss aliment ? The fork itself needs to be checked as well ?

11:25 does it take a snapshot of your car too? And are you allowed to look through a sight while driving? Or are those only for when you're stationary

Cop speedometer that works on LIDAR and RADAR somewhat works the same way, they do time of flight calculation basing on the distance calculated from the distance between the emitter, object and back to the sensors, and remember that while it do continuous calculation of the sent vs returned emissions to be timed against, for computed speed (generally displaying speed in MPH and KM/h). RADAR is generally somewhat inaccurate in some circumstances owing to the longer wavelength compared to laser light - it can be viewed as low resolution image presented to the RADAR sensors compared to the shorter wavelengths of light (in this case Infrared laser light), so LIDAR is usually used whenever accurate measurements are a must (the computer in LIDAR speedometer is also smart enough to ignore any Infrared light that didn't come from itself, so measurements are generally good with those).

Great job, thanks.

Thank you for the video as it was very informative. I have a question about Laser LIDAR. When you are it using towards a vehicle do you get a return signal if you aim it at the windshield of that target? Or does is it bounce off a different direction due to the angle of the windshield?

You answered my question about multiple cars!

Question so is the speed radar always on or you guys turn then on when you think you’ll see someone speeding . Like for instance a cop at a light and you coming from behind it will he have your speed locked in ?

Thank you for your video. How soon after a vehicle is visible in your line of sight are you generally able to pick up a speed reading?

Nice video! Thx! Be safe out there!

The radio/emf waves from your radar and lidar both travel at the speed of light (actually slightly less on Earth). Lidar waves are just much smaller.

Radars o speed detectors work if cop is driving on highway too? or need to be stop the patrol? i mean if cop is doing 60mph and car on the other line its doing 65mph he csn use the radars etc to check the car speed? or only with the patrol speedometer while cop patrol is moving?

Nice Video sir! Curious though. How do you lock in to the exact vehicle? For example you clock someone going 80 and your parked. How do you pull off and catch up to that vehicle and not lose it in the sea of other cars?

great video. am owner op truck driver now and thinking of becoming a cop. trooper. or sheriff. also from Florida. but wanted to know how far away can the radar or laser gun pick up that you are speeding? think I heard that it was up to a half mile away but am unsure if that's correct

Must an office visibly see a car he thinks may be speeding first, or he can be not paying attention and an alarm goes off? If he must visibly see what he thinks is a speeding vehicle, how many seconds does it usually take to put the radar on that vehicle and measure speed? (From a parked, stationary police car and an oncoming vehicle)? Thank you

I sometimes see a car speed and come right behind a cop and they never get pulled over. Is this because the cop can't properly estimate the speed, is it because it would easily be thrown out in court, or other reason? I also have seen many times Troopers do 85 in a 65 and a whole line of cars following him at 85 and the cops doesn't seem to care.

cool video, I have a few questions I would love answered. 1. do you have to radar/laser the car in the front or back to get a speed or can you hit them from the side? 2. what does it look like from a law enforcement standpoint when someone is using a laser jammer. thanks!

Can you do a speed check on a car going away from you (you are looking at the trunk )?

what kind of hi vis jacket is that in your trunk?

Great videos! I got a speeding written warning yesterday. In Florida from palm beach sheriff department. Do you know how long that stays in their system ? Also do other agencies or state troopers have access of seeing that warning ?

Hello, great explanation but quick question. I had a traffic ticket I believe is false. I drove past an officer who was coming out of a parking lot an immediately pulled me over. They claimed they used a LIDAR scanner that was calibrated that morning but refused to show me when I asked to see if it was working. They stated that they couldn't show me because it was in their trunk. Wouldn't you have to have the scanner in your hand and be pointing it at the car your targeting to get a reading since its light and tracks one vehicle? Also, when I drove by I made eye contact with the officer and there hands were on the steering wheel, getting ready to make a turn so I know for a fact they were not using a handheld scanner. I was also following behind a car when I was stopped so I believe they may have had an inaccurate reading. Thank you!

Personally I no longer use the vehicles speedometer because it's usually off +/-3 mph. New tires travel slower versus well worn tires which travel faster. I use two GPS speed indicators, one on crashcam recorder display, and the navigation unit. Both are 99% in agreement. To verify GPS speed, I also use ground based communication towers which usually matches both GPS units. I also have a 4th separate speed indicator which uses PCM data calculated off my programmed inputs. I mounted the 4th digital indicator slightly left and below center of visual field so it's easier to see and I now use it for primary speed information. Factory vehicle speedometers only give general speed information but cannot calculate for tire wear and inflation pressure. Overinflated tires register faster, versus underinflated tires which register slower. I learned that trick back in the 1980's while working at Yellow Cab Company. During vehicle and meter calibration, we set tire pressures at posted. Once back on the street, we'd over inflate the tires by 10-lbs which caused the fare meters to tick even faster for higher fares which worked beautifully on longer trips such as airport runs.

Where can i buy the speed detectors?

Have u ever found someone was using a laser jammer and how do u feel about radar/laser detectors.

Wow that is a great topic to talk about bro , is that your departments ar15? Looks like a nice build

Which do you use most radar or lidar?

I always wondered how a cop going in the opposite direction, both in the far right lanes, caught me speeding. We assume it's only the speed trap cops that pull you over but nope, they apparently just set their gauge on the dash board. That said since we were both driving (opposite directions), could I have requested to see the gun that clocked my speed? I don't think he could have done the lidar one while driving, so i assume it was radar.

Can you use the laser at night? I don’t think I’ve ever seen them used at night. Only radar.

Will radar pick up on 2 cars “speeding” at once?

Very kool. And what's a "virtual radar" ?

Wait until I get a light absorbing paint job, thanks for the information

Hey I have a question, I have a radar detector and it told me i got lasered on the free way when i was going 85 on a 65 but no cop was in sight and i didn’t get pulled over. I was wondering since i got lasered if i will get a ticket in the mail or something even though i didn’t get pulled over??

Only issue I have is trust that the officer is honest, with technology today it should take a photo of the infraction so there is no doubt which car it was. Its sad we cant trust every officer to be truthful about protecting and serving.

Can the Lazer radar detector detect your devices?

Fantastic video, sir!! Thank you for your hard work and dedication. You should do some ride along videos, sort of like a Vlog.

That was a very informative video. Thank you !

Is there a delay in getting a speed reading? My radar detector went off today when CHP hit me with their LiDAR gun, but I slammed on my brakes instantly and didn’t get pulled over. Let’s just say I was hauling a** down a hill.

If you’re approaching a vehicle that’s 150- 200 yards away going the opposite way will the radar continue to be accurate or is it more of an estimate of how fast the car was going . I was stopped going 67 in a 55 but I was pretty sure I was going 62 .I understand I was breaking the law either way I’m just interested in rather that 5 mph dispute can be proven .

So prior to being able to take the course what did you do to check speeds?

How far out can they reach?

Can the Lidar device be used while mobile if two officers are in the patrol car? Thank you!

U seem like a great officer. 💙 I'm from another state but I just visited Florida. Thank u for serving ur communites. 💯💙

So crazy to see how other states are allowed to use LiDAR and radar. In Pennsylvania only the state police are allowed to use radar and LiDAR so municipal departments usually have to pace you or some use the enradd system which sets up two lasers one on each side of the road and when you pass through it calculates your speed. I know there’s another method where they pick two points or lines on the road and then use a stop watch and a math equation to calculate how fast you were going in those points or so I’ve heard

Can an officer clock your speed if he's DRIVING (not sitting clocking but driving) on the opposite side of the street as you?

I just got a ticket for going 79 in a 55 I was definitely going 70, not 79. Yes, im aware that is still speeding, but, i believe the car to my right was going faster and I think he discriminated against me because I have a challenger. It was very heavy traffic on a nice sunny day. I was going exactly same speed as car in front of me, and all the cars in front of him I was in left lane, several car lengths behind the car in front of me, because I'm a safe driver. Cop pulls me over from 3 lanes accross heavy traffic blocking his view Of course, afterward, other people blow past me weaving in and out of cars, driving like complete savages, but, the cops never there when people are actually making the road unsafe and need to be stopped. Instead, hard working people like me, who are driving completely safe, have to deal with cops and their draconian bullshit. Good job

So....if I had the same laser, lidar and shot that pulse back to a police officer scanning my car at the exact same time, in theory, would that jam the signal? Ideally, you want to deflect or absorb the wave arround your car, so the wave is not reflected back...

Serious question can you use laser radar through trees?

This is big brain.

When using the LIDAR (laser radar), the laser light has to come back to the device in order for it to calculate the speed, which is done by reflecting off of the vehicle. Therefore, doesn’t the device have to be pointed directly at the vehicle?? If the laser light is not pointed directly at the vehicle, the laser light will still reflect off of the vehicle but at a different angle that won’t come back to the device, RIGHT?? And, I'm guessing the device will still give a calculation, a false calculation, even though the device did not receive back the laser light; is that correct as well? Please let me know.

What is CLOCKED AND STIMADED??? on SPEEDING TICKET?????

Impressed with the certification-training officers have to complete prior to performing speed work. Thanks for sharing that. What's the fastest driver you ever tracked?

Dang this video actually helped me understand hella stuff thank u bro

Can cops use laser on the highway or do they just use in cities??

What I've always wondered is if your facing on coming traffic at night on the highway and a speeder goes by, how the heck can you pick that car out in the dark in traffic.

One night I was driving the speed limit but there was a car behind me about 300 yards I could see headlights behide me but there was a green laser pointed on the back of my car then in my car kinda got scared so I turned off the road it followed me so I did a few turns and the car stopped following me was it a cop I wasn’t going to wait and see if it wasn’t

so i could pass a 40hr police training course for measuring speed after watching this 15 min video.... sounds about right...

5:25 do you REALLY check it before and after EVERY shift? .......... be honest :D

Hold on, you point something that looks like a gun at an oncoming vehicle ?

Enjoyed the video. Explanation was made easy to understand. 👍

Thanks officer. I enjoy your presentation. Make home your last stop. 😊

Tracking history

My uniden r7 radar detector finally went off on laser and Ka band today. I was pretty excited when fhp clocked me 😄 .. didn't get pulled over hehe

If you're having trouble falling asleep just watch one of this dudes videos. 🤣

Great info🤗

Lidar jammers work awesome anti-laser priority get them stalker doesn’t have a chance

My first ever speeding ticket was with a laser gun. He ranged me at 1400ft which is super impressive. My radar detector picked it up so I was able to immediately know I was busted 😂

One thing I hate is when I’m on the highway at night by myself going 10 over in my mustang gt finally able to let the car somewhat do what it was made for and a cop wanna mess with me like I’m by myself and 80 in a muscle car feels like 60

🐝 careful with striking those forks on anything other than a soft yet firm surface (like a boot heel) The forks can be damaged and/or thrown out of spec

Light travels at 300,000 km/s or 186,000 mp/s

If a cop has its radar on while driving around and my radar detector squeals at me and I slow down, does he know its me in the crowd who using 1? If its not illegal in your state to own shifters on your car for deflecting lidar or how ever it works would a cop still stop me?

This is hella scary, I need to move to a third world country where this technology doesn’t exist

Which country r u in duty

How the hell I had digital cruise control set at 79 in a 75 and jack ass sheriff pulls me over saying I was doing 81 MPH? I was driving 2021 Ford SUV with original factory tires vehicle only has 10K miles so who is wrong ?

Radar detectors are your friend :)

you should do a vid on the cosine effect and radar/lidar

You only tested your radar for clocking in the stationary mode which was not a full proper test. The sole reason radar manufacturers provide 2 tuning forks to test with is to test the unit in the moving mode. First you test in the stationary mode exactly as you did. Next place the radar in the "moving" mode for traffic coming at the radar. tap the longer (slower) fork first and place it in front of the radar antenna head approx. 3 to 5 inches away. That should show up in the Patrol Unit speed window. With the slower fork still reading in the window, tap the faster speed fork and place it in front of the radar antenna head about 6 inches behind the first tuning fork. The reading in the "Target" speed window should read the DIFFERENCE between the two forks. Example: if your two forks are marked at 35mph and 50mph respectively, the patrol unit speed window should read 35mph and the target speed window should read 15mph. Third, switch the radar to moving for traffic moving away from your radar. Now tap the smaller (faster) fork and move it in front of the antenna. That faster speed should show in your patrol unit window. The tap the larger (slower) fork and with the smaller fork still being read, place the second fork about a foot behind it. The reading in the target speed window should read the COMBINED speed of both forks. Example, using the same 35 & 50mph forks your patrol unit speed should read 50mph and your target speed should read 85mph. this tests the math processor in the radar to be sure it can properly calculate the patrol unit's speed and separate it from your target speed. I was a cop in the Dallas area for a little over 16 years and have been to the LIDAR/Radar school. Next time you're in your unit, give it a test and let me know what you think. Sometimes defense attorneys will bring a radar test unit into court and have you demo the test procedures. It's good info to know. Be careful out there.

When the speed meter is stuck at 0 km/h, that means, the driver is a killer, and he is at large. Monitoring systems oxidize its mechanic parts, forcing sky net cameras to switch to speed measurement. Normally, a satellite reads the radioactive pointer to log the speed of a car. When a murderer escapes from the cops, higher levels of monitoring can track the killer at higher expense for better result.

Good thing I have a radar jammer lol

how they catch you: First, they are born, grow up, go to school...... **20 minutes later**.... Complete their radar training..... **20 minutes later**...... And point the gun at you as you drive by. I just want to learn how to avoid em haha. I'm just messin' with ya. Interesting video.

Is it worth it to become a cop

14:10 in the video. The fork you said was for 25mph. Your radar showed 26mph. With how much you talked about how great the radar works and you have never had issues with its function, I was not sure if you were trolling or not. 😂

Dude I'm not even a cop but I do this all the time because it's fun

You are awesome bro I’ve always wanted to be a police officer it’s my dream to be one

I get told alot if you don’t hit your breaks they won’t know your speeding….. the people that told me that I geuss they want me to go to jail I never go over 65 tho unless I’m on an Interstate.

Wow I didn’t know police could use Radar Guns while driving without a partner holding it. I Better be more careful near them on the streets 😅

Good video and greetings from an ex 16 year police vet from a suburb city in the Dallas area. I have been to the radar school put on by Kustom radar. My only comment would be on your radar testing using the tuning forks. That was only half the test and only checks the radar for the stationary position. It does not check the radar units math processor to verify that it is accurate in the moving position. To check that you use BOTH tuning forks. 1.) Place the radar in the "Moving" mode. 2.) Tap the low rated tuning fork and place it in front of the radar unit 8-12" away. That speed should show in the Patrol Units speed box. 3.) Tap the higher rated speed tuning fork and place it approx. 16-18" behind the radar and lower rated fork. ( the two forks should be about 10" apart) The box marked for you Patrol Unit speed should still read the lower fork reading and the Target Speed box should show the DIFFECENCE between the two forks. Your higher fork was rated at 40.25mph and you lower rated fork was 25.25mph. Thus a proper reading on your test would be 25mph on the patrol unit speed and 15mph on your target speed. That is the entire reason they always give you two tuning forks rated at different speeds when you buy a radar. Otherwise you can only verify that the unit is working properly in the stationary position. The brand of your radar makes no difference at all. Next time you run the fork testing check it out and let me know. Also I'd suggest calling the radar manufacture. (any of them actually) and they will send you a booklet on the testing. Been out of the job a few years but I'm certified in the Doppler Speed Radar and the LIT20/20 laser by Laser Technology Inc.

I'm "alright"

That 40 hour class you probably had to pay for on your own sounds absolutely ridiculous.

So basically my lawyer is about to have a field day in court then. Cop says he used his radar to clock me while he was driving in the opposite direction of me, but he turned on his radar and while we were both driving in opposite directions of each other. How sway?!

My cat strawbs I thought the staked 11 said strawbs

Here is one of my favorite toys for avoiding a Laser speeding ticket and any encounter with Ole Smokey :) kzfaq.info/get/bejne/gKilfpx9zZfLgo0.html

Lidar is easily defeated using laser shifter technology. Look to spend $1000 to $1500 for such countermeasures. Radar on the other hand uses radio waves, which is governed by the FCC. Jamming radar, or radio waves is a serious crime. Since lasers use light, no one governs light, making laser shifters quite legal.

Wait none of them captures the plate or a photo of the car? Disputing my next ticket 😆

yeah its fast...like the speed of light

So there is no proof that a cop actually used the radar or laser to test speed? He could just say he used it and make it up?
