Can it detect at night?

It works in the dark just fine, it senses infrared heat energy moving in the zone.

Night vision works pretty well. It's a small screen. I would not use it to try to find my way in the dark, but you can see objects.

yes it activates at night only. it has stakes which atach to light to be put into the ground and adjust to aim where you want. we purchased for our flagpole, cannot be mounted. put into ground aimed at flag, not bright enough.

I haven't tried it, but I think it would work at dusk or in the dark, as long as your distance isn't too great... Remember, all it does is give you a level -- You would have to measure vertically from the laser line based on the height of the laser at the base.

Yes. It stays on at night. Whether it will satisfy as a night light depends on how bright a light you need.

You will notice it especially if you are outside in the dark. I have not paid much attention to it because we wanted this device as an interior alarm in our office. But I think it will do what you need in a situation.

No. The unit has a light sensor that will not allow motion sensor to turn on until dark.

No. The motion detection would be controlled by the DVR. This is a standard analog camera with infrared for night vision.

Yes you can read it day or night. It emits a green light as do the clocks on my microwave, and stove.

no, it is not a motion detector. it comes on when it is a certain level of darkness and goes off with a certain level of light.

It works ok at night. If you want to see clearly you may need to either buy a ptz camera that has IR illuminaters built in, or buy a IR spot to light up the area you need to see the most clearly at night.

It does work at night. It uses an invisible beam of light and it alarms when the beam is broken. It uses batteries, so be prepared to replenish as needed. It would be very effective to wake up a sleepwalker, just be sure to have the beam high enough that it is not over stepped.

Yes. The 2 lights in the middle come on at dusk. When it detects motion the big bottom light comes on.

Yes. In daylight use the detector . Used it to set grade on a lot last week . Have also run lines and set foundations with it

yes! It willl also detect fans, stereo speakers,refrigerators, other normal household items. But it's biggest advantage is to identify much smaller and less powerful electo-madnetic anomalies such as insects from another sector the light sprectrum - for instance, creatures from the infra-red and ultra-violet sectors and the less powerful energy left behind from ghosts.\Good luck with your meter and have a lot of fun identifying objects other than by the naked eye.

I have not used it at night but it works well at dusk. Cant beat it for the price. You want something that works at night go gen 3 night vision or thermal, but $$$

Mine does pretty well at night. Depending on your headlights you can probably get license plate number of the car in front of you while at a stop light or stop sign.
