Can this be set to detect movement in daylight to set off an alarm?

Yes it can. It will detect body heat only and large pets. I would avoid placing the sensor in direct sunlight. It will stay on from 10 to 15 seconds.

I think you might be asking about the switches that keep light on dusk to dawn, or only when motion is detected.

Yes, this would work fine for that. In addition to the motion detector, use the window/door sensor... Great idea!

If it was powered by regular power it might have that option, but since it's battery powered once the sensors realize it's night it automatically turns on when movement is detected. No need to mess with any switches.

Any movement will set it off, including changing light conditions. If your sensor is exposed to the direct rays of the sun, it will likely go off because of the stray infrared rays. You might want to move your sensor to where it is not exposed to the direct rays of the sun, and read this: http://www.ehow.com/how-does_5748164_infrared-alarm-sensor-work_.html

You don't want this one then. This is a motion sensing switch that triggers when an object passes within the zone of the infrared sensor. You want a photocell, which triggers when there is a sufficient change in light. They are called dusk to dawn switches too.

No. It needs a timer and can only be changed from day to night by hand switch.

There is a 3 way switch on the light which allows dusk to dawn or motion sensing. The answer is the light is capable of both functions. I had a hard time getting it to be a motion light. It took many tries but finally it worked. It should not have taken so many tries.

Yes, once the sensor knows it is dark - it becomes active. The unit stays off during daylight.

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.

I do not believe so. I found the programing for wake, leave, return, and sleep were easy to set. Hope that helps.

Yes, I think there was a switch to set how long you want the light to stay on when motion is detected.

The answer to the first part is a little complicated. I don't see an option that allows setting an on/off event which is offset in time relative to dawn/dusk. However, it does let you define the dusk and dawn time during the initial setup. So technically, if you set the dusk time to half and hour before it actually occurs, that should work. The answer to the second part is definitely yes. You can set it to go off at 1 am or any other time of the day, down to a specific minute.

There is NO MOTION SENSOR ON THIS FIXTURE. It is strictly a dusk to dawn unit. You could wire in a separate motion sensor to control the light. If the fixture "sees" daylight it will turn off. I don't know of a reason to have the light on unless it was "dark".

No, I don't believe it can be used for dusk to dawn lighting. Mine only comes on when motion is detected.

Yes--it has an auto motion sensor, but I prefer the timer--I set it to go on at 7 AM and off at 11 PM and it works beautifully!

Yes--you can also select how long the display runs before it turns off. The specs say it detects motion within 10 feet, however I have found it will turn on from about 15-20 feet.
