It is a common complaint, for sure, but I’m not sure what’s behind the issue. Settings, mounting angle, odd network issues, but not wake up time or sleep mode, also for sure.
Why do I say for sure, because I have a camera in a position where the approach can not be seen until the last moment, when the person approaching appears from behind a wall. With my camera set up as it is I have never knowingly had a failed trigger. More to the point, it always, and I do mean always, triggers in the exact same spot, which must be a tiny fraction of a second after the appearance of the person in question.
To demonstrate this point I have posted this video a few times, but I could choose any of hundreds, or at least I could, if I hadn’t deleted them. In this case I will post the first frame.
At walking speed they are probably at the door in not much more than a second, so the first frame must be within about a fifth of a second. Again, this is every single time I receive a trigger.
They are not slow, by any inbuilt default wake up time, or similar. The whole point about the chips used is their incredible response time to wake up from sleep.
In this shot you can see that he may even have been hidden behind the bush, and it got him really really quickly, but even if you take it back to the wall, and it ‘saw’ him through the bush, it is still damned fast.
