How far this device can start detecting speeds, say an approaching car?

I was able to track the speed of a car at about 200 feet. The farther away the object is, the less accurate the reading is. And the more objects that are moving in the sight of the gun can also confuse it.

I do road work and mainly use the radar as a training tool for my kids. They are both pitchers for baseball and softball. I had the radar gun in my truck at work and we started checking speeds of passing cars for the fun of it and I would say it easily was picking up cars at 100 yards away that were driving at us.

The larger the object, the greater the detection distance, however dont go beyond 200 feet to limit errors. For smaller objects like a baseball or cricket ball, you should not go beyond 60 feet.

Keep in mind that when taking a reading on a vehicle, you will only get an accurate measurement if the vehicle is coming directly towards you (you're standing in the middle of the road). Radar Gun will not compensate for lateral movement as a Police Radar gun will.

If I recall, there is a sensitivity setting. And no, there is no away a car will set it off. Its detection range is limited.

It's kind of from the camera to infiniti (as far as the camera can see). Varies with the amount of light the camera "sees" + the size of the object in motion. One camera we have set can detect motion from about 40 to 50 feet away, with light from passing cars on the street further than that, maybe 60 feet. It records 10 seconds before the trigger event, then as long as there is motion to record. It has also recorded small moths that has flown in front of the camera (unexpected sensitivity). VERY pleased with this product & it's capabilities inside our home.

It needs a full field of view of the road. it will detect below the dash but the range is almost nothing.

You can have it show speed (mph) instead of pace (min/lap distance). There's an option in the setup menu.

This is not actually possible. This unit is only a detector. It detects a small shift in a magnetic field. Your car is a big enough piece of metal to make a small shift in the magnetic field. This unit then sends a signal back to the receiver. However the signal is nothing near the same frequency or complexity of car security systems. I am sure something else "deprogrammed" your cars security

Detection range side to side is real close to 180deg. It is quite sensitive of my movement even at the end of this range! Also, it does not seem to be activated by tree limbs blowing - amazingly. Distance for detection of a person (for mine at approximately 10 feet high) is about 40-50 feet. I am VERY happy with this item. It lights my entire path from the car to the house and stays on while I am moving. Very easy to adjust to preferences too.

Yes the motion detector should work for this purpose as well. You will have to choose the correct spot in your driveway to sense the area where you want (the manual will guide you). Great system, should meet your needs.

By the way. It's already saves me from numerous tickets. Detector has light that you can mount and it flashes. As I would never hear it beeping at 100mph

I would imagine there would be distance limitations with the device. Experiment!

I used it on cars and buses just for a test, and use it regularly for softball pitchers. I tested it on cars in urban environment, so the speed was low -- 30 to 50 mph -- and standing on the side of the road. Product description gives ranges which I could not test. For softball it works fine.

It doesn't detect "police near by when driving", it detects the speed radar that police use WHEN their radar is on. Police are well aware of people using these detectors and keep it off until you fly over the top of a hill and you fall into their speed trap, then they'll turn on their detector and you're done. Hopefully, your detector can detect that happening to the car(s) in front of you and you will know better then to speed as you drive through that area.

Yes, if your vehicle's speedometer is accurate. Just point the radar gun at a fixed object while your vehicle is moving, and compare the reading with the speedometer.

I just checked the instruction manual, and according to it the range of the speed is 0 - 99.9 Km/h, which means 0 - 62.07 Miles/h. So I think it would work fine for you.

I just tested mine. It picked up the signal about five inches from the iPhone. So not very far away. I was in my kitchen spinning the sensor with my finger.

I would not expect it to. The Amazon site claims "Motion detecting range 40 ft Operating range up to 800 ft" Can you place the sensor within the 40 ft of the mailbox? I would expect yes and it would definetly sense the car. However you want the receiver 300 yards away. I believe that would be 900 ft which is 100 feet beyond an ideal case line-of-sight no obstruction situation which is the norm for a manufacturers specification. My general experience would suggest that if you get half (400ft) the rating under good conditions, you're lucky.

I dont know the exact range but my lights will detect motion at least 20 feet away
