I do not use me for surveillance against intruders to spy but a couple of birds that had nested in my garden. To the delight of my 6 year old daughter, we can now observe the mother bird smoldering while dad brings food.
Thanks to the night vision, we have seen that the mother bird was well set up for the night.
The trigger recording is handy for capturing times even sympathetic it fires a little too right now because of strong winds (it is set but I have not yet found the right balance in sensitivity) . When the bush does not move too much, it works very well.
So happy with my purchase, which can be used later to observe small animals that roam the night in the garden, even for basic video surveillance. In any case, it is not sold for naturalistic observation but it works very well. :)
