I was hoping you would respond, Soundy. Your answer makes sense and I know that it can vary widely and maybe airports was a bad example. Schools was probably a better example, but I know that can very as well. I just see people sometimes calculating motion at a schools at 50% or more but in my experience, motion at a school doesn't usually go above 20% or 25% across a 30 day period (which seems to be what most end up recording for). I agree wholeheartedly that it's definitely better to overestimate and you can never be exact but if your customer is asking for 30 days and they end up getting 60 because you overestimated then they're likely to start questioning why they spent the money on twice as much storage (if doing a server/storage solution) or possibly twice as many DVR's if doing an analog solution. I figured it was a long shot question to begin with. Maybe a better question should of been "how do you guys go about calculating how much motion a particular installation will see". Sauce

I looked through forums here and Googled quite a bit and couldn't find anything on this. I am wondering if any of you have run across anything that gives "typical" motion/activity percentages for different installation environments. For example, something that says Airports on average have about X% of motion, schools have about Y% of motion, etc. Something like that would come in handy because I think a lot of times that motion/activity percentage is overestimated by a large amount when quoting a system which could result in you losing the job because you quoted more DVR's then the other guy or more storage. What are your thoughts and if you have come across any white papers or anything like that dealing with this topic, please point me that way. Thanks, Sauce
