VIDEO QUALITY
By default the TN1600P comes with the quality slider at the middle but i do recommend moving it all the way to high quality spot (the above screenshot is from that).
I decided to cut a small part of the picture in medium and high quality so you can see the difference in quality (mostly a tiny difference in sharpness) for yourselves (top is medium, bottom is high).
As for night mode well the tree leaves in the above picture are approximately 3m away while the houses at the far end are 40m away (the illuminated area even further is roughly 70m away). You can't see the effective range of the 30 IR LEDs here but after further testing we found that you can see easily up to 15m away (20m is also visible just not as good).
