So I went through the whole fight of trying to make pixel based motion detection work on my camera systems. Results ranged from the feature being pretty much useless outdoors or anywhere near windows to halfway decent inside rooms with no windows.

My question is... isn't it possible to just use a heat based motion detection like on our everyday outside lights then interface that with the contact closures on the DVR? I know you can even separately buy the sensor part and wire your lights however you want.

To that effect, what is the story with "built-in" motion detection on cameras like a Speco 7246? They have the alarm out wires. Are they actually doing heat based motion within the camera or is that just pixel based as well?

Suggest some of the system that have failed when you try them. Maybe someone here has had success with them and can offer pointers. Not even mentioning a brand is a bit of a wide reach for advice.
A good answer is easier with a clear question giving the make and model of everything.

It is pixel based.

​Not sure how well the Speco works but other pixel based motion detection allows you to set the sensitivity and mask areas as well.
​I usually setup the motion detection to be very sensitive, so it is recording often. Better to have more, than to not have enough and miss needed footage.

​If you are setting up email or push notifications, then you usually don't want to go that route - you will get massive false alarms all the time. Or if you set it to low and mask off to much, will miss needed notifications.

​Better to use a separate motion sensor for these situations, triggered back to the DVR.

Yes I'm talking about notifications. So you can do that?? Use a conventional motion detector made for security lights and wire back to the DVR trigger inputs??

Yes, before I was trying to do email notifications with pixel based DVR function. Worked okay in interior rooms but useless outside or near windows. I always do Continuous + Motion recording at the same time.

Warning – Shameless pitch to follow: A favorite surveillance system of mine uses powerful analytics to address this challenge [Link: snapav.com] In my use case I have cameras on the perimeter of my home that I “arm” and “disarm” notifications for. In addition, these cameras are connected to a live monitoring station for human visual verification to contact authorities whenever someone steps onto my property if my traditional security system is armed way before they even reach the physical perimeter of my home. Furthermore I use a geofence rule in my control system to arm and disarm as I leave or return to my home just in case I left the home w/o arming the traditional system.
