Would this sense a car at the mailbox 300 yards away?

Yes, just make sure that the detector you buy goes the distance. They are different. I bought 2 detectors. First one set up about 450 yards away and then the 2nd one about 100 ydsaway to let me know when someone is closer. I love them !

Possible. This motion sensor can only see about 30 feet if you point it down. Point it up and the wind will set it off. This means the sensor is close and receiver has a short radio wire on it which could possibly receive a sensor signal from a long distance.

Not unless the sensor and base are in direct sight of each other and the distance sounds a bit much.

I would not place a motion sensor 300 yards away from the mailbox to alert you when someone is delivering mail to your box. At 300 yards, the sensor will pick up a lot of other movements - birds, etc... Best to put (screw/tape it down) the sensor inside the mail box. It has been three months, and the batteries in my units are still working good. You question is probably whether the receiver can receive signals from a sensor that is 300 yards away. You will never know until you try it - every situation is a bit different. The signal can be easily blocked by multiple walls, etc... I have tried up to 100' (size of yard) and it still works - 300 yards is very, very long way away.

I use this over my garage door and over my patio. The range is fine for these areas relatively close to the house. But 300 yards is a long, long way for this type of device. I do not believe its range is that great.

The range listed in the specs is266.7 yards. That's a little short of 300 yards. Mine works great through around 150 yards of wooded area. Depending on your terrain you MIGHT be able to reach 300 yards if it was clear line of sight and no trees or other obstructions in the way.

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.

yes we have one it is 300-350 from house, it works well, to well sometimes, neighbors cat sets it off. we finally put cardboard box around it (like blinders) works great.

One other possibility other than wind for a false reading is a heavy truck passing by. If it can vibrate the pavement it can shake your mailbox adjacent enough to set off the reminder.

We put ours too close to the entrance of our circle drive and it usually failed to alert for cars coming in if they drove close to that side. It never failed to alert on cars exiting the driveway. The range is really good so if you have room place it a few feet back.

The ones in my area appear to be about 30-35 miles away. Not sure how far away it will pull in signals.

No. Our mailbox is about 80 feet from the receiver and the signal has to go through two walls and a metal garage door.it works great. We love this thing.

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

Yes. mine from Amazon had the control box. I would say that about 60 miles is the limit in distance.

I have the sensor nailed to a tree about three feet off the ground. It is very sensitive. I think installed at an angle above the garage would work. The receiver in the house works very well and beeps three times everytime something passes the sensor, could be a car, animal, or garbage man. Do not put the receiver near metal like a microwave it seems to block the radio waves. Also when the transmitter is rained on sometimes you get false readings. I put a plastic shroud over the top made from a yogurt container. Overall I am very pleased with the product and for the price it is a very good value. I highly recommend this product.

You can turn off the car with the key fob, but you have to be within about 300 feet.

My gate is 300 feet from my house. The antenna wire comes out toward the house. On most days it works from the house. On the street side I have to be a little closer because of the antenna wire location.

Yes it can & a good system at this price point, Night vision isn't good on fast moving objects and you can't read a car's license plate if moving. But you would pay big bucks for that type of system. Hookup is easy. My receiver was a brick wall and a drywall away. approx 35ft. works great

I'm not sureof the answer but I for sure want to test it to be sure of distance. I tested it. It seemed to work ok. There is a date on it when u get it.

I believe so. We have our unit positioned far from our house along a lengthy driveway and it detects someone walking by or animal (deer) movement.
1355448
It would give them a surprise. Just make sure you have the distance calculated!
115649
yes, I think it would. It is a pretty clear picture. You would certainly see the car. I don't know about distance. I use it to look in water ways of washing machines, looking for socks. I don't know how close you would have to be to read a license plate.

To answer your question we have not tested that far of a range. The sound gets weaker and fuzzy from the backyard to the family room.

Takes 2 people to test it to see how far it will go. Keep it line of sight clear to driveway along edge you want monitored. Put receiver near window close to transmitter as possible.
