Can you adjust the sensitivity so the system only picks up cars and not people in driveway?

The system is basically an infrared variance responder. Anything that throws contrasting light in the field of the reciever will cause an alarm. Fast changing light on a cloudy day will set it off. Basically, there are no sensitivity adjustments available

Not to my knowledge. We have a cat in the neighborhood that typically sets it off every night at pretty much the same time, so it would be nice to have that adjustment to pick up cars and/or people.

I don't think so. It even picks up my neighbors cat, it's pretty sensitive.

It would be difficult to differentiate the difference, because a car is so large compared to a person and also emits more infra red energy (temperature) than a person. Yet if a person passes by closer to the detector than a car, the response would be similar. What you are asking is difficult to do. If you combined a video camera system with the alarm system then you could visually verify whether the alarm was due to a car or a person however.

you can only change the window that it looks at. It will pick up any temperature difference in the window it is looking at. It will pick up rabbits and people in the same area.

If there is I haven't found it and don't want to. Its a great warning for uninvited visitors. If it is your children in the driveway or something of that nature I'd just turn the monitor off. Well that's my 2 cents, but having had the monitor for 4 years now I haven't seen any other sensitivity adjuster other than the little window blocker thing you put inside the monitor to adjust left and right and up and down vision.

The sensors come with various plastic 'filter - shields' to be inserted to control the pattern area to which they respond. I gave up on these years ago as a lot of screwing around with them was a drill in futility. I use the sensors as-is. I think if you fashioned a filter shield to severely attenuate the signal, this might be accomplished, To wit: screen wire or cheesecloth.

I've used black tape on the inside of the translucent sensor cover. I've blocked off areas where the cat jumps up on a washer and dryer.. It seems to me, you could cover the whole inside of the sensor cover, except for a small round 1/8" hole in the center. Aim the sensor at the driveway and it should be able to sense cars, but not much else.. You might have to make the hole larger or smaller to get what you need. The range will be limited by the mask. It should be high, and pointing down into the pavement. So nothing in the distance can trigger it and so dogs won't walk into the detection cone, close up. Like 2 feet away. Dogs emit a lot of heat.

Yes, you can adjust the sensitivity. And for me it keeps dogs out of my yard and also worked last summer in keeping bears away from my garbage cans.

When it senses motion within it's range it makes a beeping sound. The volume can be turned off or set to low or high. The directions suggest the width of it's range can be adjusted by adding strips of tape to narrow it's field. I have not tried that. It sometimes gives me false alarms if a particularly large or slow vehicle passes by, like the UPS truck or the mail truck. Because my garage protrudes from the front of my house, my view of the driveway is blocked. The signal has proven very helpful in alerting me to someone in my driveway.

Yes, you can set the sensitivity to your preference.... In fact, it can be so high that it will go off if someone slams a door in the house!

Mine is mounted about 12 feet up, and it has more than enough sensitivity to detect cars and even people in the driveway below. And I even have the sensitivity turned way down to prevent detecting tree motion due to wind.

I have this in my car and it picks up any ambient noise including road noise so it most likely will pick up noise from a different room. There is a sensitivity knob to change how sensitive it is to change the light color based on the noise.

I believe if you get the parallax sensor they convert to digital signal. You can set limits with the range. I'm not sure what sensors you plan on using.

I'm pretty sure that is a setting that can be changed on the vehicle settings. Refer to your owners manual for instructions. Hope this helps good luck.

possibly so. i know that anytime something is in our driveway it beeps. i'm not sure of the sensitivity level.hope this is helpful

There's a button by the knob that enables/disables the EQ, but the internal switch on/off switch is controlled by a wire that I connected to the same wire that turns the head unit on when you start the car. I suppose you could connect that wire to something else if you wanted to get creative.

The manual implies up to 50 feet. I deliberately aimed my unit to try and cover a limited area, but it seems to detect people at about 25', cats at about 12' and moving cars at about 40'. I'm sure the range would be greater if I aimed the sensor up a bit more.

It is not directional. Passing vehicles will activate the alarm provided sensor is not more than 4 feet from edge of driveway. It works great for me. Wade

I found that mine was picking up cars going by outside my building through a window. Also mine quit working altogether second day then started working again day three.

I use this because we have a long driveway and it alerts me to people driving in so I can come to the door in a reasonable amount of time. It just gives a two tone signal twice and that's all. Because mine is in the driveway, the deer set it off. But since they usually come in groups, if I hear more than the usual signal, I know it's the animals.

I have the same situation . You have to loop wires in front the whole driveway .

Not really it picks up any type of radio frequincy though like in my car no radio no activity turn on radio then there is activity-also goes off major at traffic light cameras and convient store camera, as far as finding any hidden pin hole cameras i have not

Don't know about IR. We have on driveway and are looking for an alert when someone pulls in. Can't see end of driveway from house so this is a great security for us. This does trigger all animals so it goes off in the middle of the night sometimes.
