Hello,

I am going to work on a project, which requires reliable movement detection.
It needs to work for approx. 1 year, with multiple movement detectors a day.

I have thought about using the MaxSonar sensor (http://www.adafruit.com/blog/2009/06/23/getting-started-with-the-maxbotix-sonar-sensor-quick-start-guide/), but I don't know if it will be precise enough.

The sensors will be placed at 3 different locations at a spiral staircase, and should be activated when people are present in it's area.

I got suggested that I could use surveillance cameras as sensors, since they have a built-in trigger for when movement is detected, and they should be more precise and reliable.
I also thought about using webcams, but since a computer won't be permanent available in the setup that won't be a solution.

Any hints for how I can accomplish this task?

What happens when the motion or presence detector is activated?

What makes you think that running for a year might be a problem?

Is it motion or presence you are trying to detect?

If it's motion, what kind of motion?

You might want to consuder IP cams that are standalone.
Consider the daffodil. And while you're doing that, I'll be over here, looking through your stuff.   8)

No problem. Just put it within range of an electrical outlet.

And will the sensor know that there is someone near, if it is not active? I think you have that concept backwards. The sensor is always active, monitoring for motion/heat/whatever. It outputs a different value if there is something present than when there is not.

What is it that you're trying to detect movement of? If it's people, do you care about knowing how many/where they are, or just that there is somebody moving? In the latter case, the solution adopted for every burglar alarm and security lamp seems to be a PIR sensor and that suggests it's the simplest and most reliable approach.
