Does it work at night

Yes, sensitivity is unchanged at night. The sensor eye illuminates slightly when it is sensing. In daylight it can not be seen. This does not affect it's ability to sense motion, but if you are trying to tell if you have set off the alarm you can not tell when the sensor is in bright light. You need a helper in the house to tell you when it is working.

Yes it does. The only time we've had any issue is a blowing leaf has set it off a couple times but I still love it.

Yes, it works at night but that is very comforting for me. Even though the alarm might sound from a passing deer I like the peace of knowing it picks up everything. This is my third alarm and I will say this one was the simplest to install/set up and has worked great! The other ones worked about 2 years then quit. The sensor located outside is not noticed by visitors and once inside they are shocked when it alarms for an additional visitor passing up the driveway. It was a good purchase!

Yes and no. It works by sensing a temperature difference, e.g. body heat or the warmth of a car engine going by. If there is no discernible difference it does not signal an alert. We couldn't figure out why it did not detect our son's leaving until we realized that his car engine had not yet warmed up when he drove past the sensor but did work when he returned. Maybe we're wrong about this but it's what we deduced. It has never failed to detect a person though.

It works great - day or night! Even goes off if cats or racoons are walking down the driveway.

yes it can be activated by animals passing the motion detector anytime of day. One thing to be certain of is to keep the line of sight clear. I once parked my car in between the receiver and the motion detector and it did not work. Otherwise it is fantastic to give a heads up that someone is coming up the driveway. Mine is more than 100 feet from the house and on the wrong side of the tree it is mounted on.

No it doesnt move at all. It doesnt work good at night unless you have lights in the area. Not of the best quality.

When it works at all, it works in the dark. It picks up infared.I have it set up in the driveway of my business so I get to see it work all day. Misses a lot of cars, and does a lot of false alerting with nothing around.

Yes it will work outside at night as long as there are no street lights around the sound is impressive but the lamp is only a MR-16 light bulb sold usually at Wal-Mart for around $6 so it's not very bright, over all not bad for the price

You can tell there on if your testing if they work but farther than a few feet in the sun no. However It's very bright at night.

Yes. It does work outside at night. I have a 120" screen indoors and it looks theater quality perfect. The specs say it can go up to 300" diagonal.

Will it work in the dark you ask? Of course it does, it's up to the task. It will work in the light. It will work through the night. Will it work in the rain? No, you might die, you must refrain. Will it work in the dry? Of course it does, it will not lead you awry. It will work in the light. It will work in the night. It will work in the dry. It will work when you cry. But to avoid much pain, you must not ever, ever use it in the rain.

No, it only comes on in the dark (had this product for a couple months now, still HIGHLY recommend).

It operates as a night light as well as an emergency light when the power goes out. However, my power has not gone out since installing it so I do not know if it truly works. But it is lite when I turn my lights out at night.
