Driveway alarm

[OUGENO]

I have a long driveway and don't know when people drive up when I am in the house. Need advice for a good alarm system.

You can get these for $14 on sale. I don't know about "good" but they work great for detecting critters, etc, for 14 bucks. Wireless Driveway Alert & Driveway Alarm System

Range is too little and batts die.. I have/had several..

But ya, found out a deer traveled down my drive every night at 10:20 pm

I had the same issue ... animals & birds triggering the alarm. I have a magnetic sensor now, but even it false alarms during thunderstorms... And when the wind or animals move the wire fence in front of the sensor.

I'm watching this for better suggestions ... maybe the old fashioned bell & hose that the gas stations used to use.

Agree on the Dakota. The wireless one I have works thru 900 feet of woods even with transmitter inside mailbox.

I had one of the HF @ $29. a few years ago and it gave nothing but false alarms!! I stood at the window watching as it triggered. I finally figured out that it was picking up the heat radiation. I tried taping off part of it to limit sensitivity but it didn't help.
20 years ago Radio Shack sold an infered alarm that had a beam and mirror. If the beam was broken it went off. I have tried to find one like it but can't.
They probably baned them because the bothered the squirrels or something.

Dakota alerts. Read the directions and you will be fine. Put a reminder in your phone to change the battery every 3-4 months.

I had the HF cheap ones also and didnt transmit far and alot of false triggers. My friend has this one and likes it.
