I agree with you. That should be like side to side motion, so it should react much quicker, assuming sensitivity is set correctly. I also take on board your comment about increasing sensitivity gives too many false alerts from a tiny leaf, blowing in the wind, or similar.
Time to wake up is not a factor, despite what you may have read. I have posted many examples, similar to above, where you see almost instant triggers and recording starts, just as kodiak did above, so they wake up incredibly quickly. If they didn’t, you are right, what would be the point. This exceptionally fast wake up is one of the features of the chip set that makes these systems possible, and is mentioned in their own promotional material.
I posted a very rough and ready test video, just the other day, to demonstrate to someone else, that it can and should work well. At a fairly brisk walking pace, after appearing from behind an obstruction, I had barely got a body width across before the recording started. We are probably talking about 0.2 seconds, or less.
Obviously this was a test video, but all of my real world videos, some of which I have also posted, are the same, when moving across the sensor.
Here’s another, real world, where I forgot to disable whilst mowing. Good range, early detection, etc. I got about 20 of those that day, as I went round and round.
I’m only posting these examples to confirm that this is not the norm, and you should probably contact support. All of mine behave as I have posted, and just like kodiak’s. I have a theory for why some of kodiak’s are part way across, but there’s no need to go into that now.
The only thing I would have done differently to you, is that I would have tested it extensively before I semi permanently fastened it up, but that’s only because I have plenty of time to do such things and I get why others might not, expecting it to simply work as advertised from the get go.
