GW Security GW5747MIC

 I did a test with a GW5747MIC 5MP Optional TWO-Way Audio PoE IP Camera 1.9mm 160° Wide Angle Night Vision Sony Starvis HD 1920P Security Mini Dome 5 Megapixel Built-In Microphone and Micro SD slot, Audio in/out Recording but the view was not only no wider but not as good in low light as the Amcrest IP4M-1026 despite it having the lowest lux spec so I stuck it looking at the bird feeder. It is also does not have the 160 view angle. Here are some compare shots at the point the cams pointed at the bird feeders flipped from day to night mode.
The supposed 0.01Lux (F1.8, Color) GW Security GW5747MIC flips to night mode first
Flipped at 17:43:42.
A Hikvision DS-2CD2142FWD-I speced at 0.07 lux @ (F1.2, AGC ON)
Flipped at 17:45:38
An Escam QD900 rated Color: 0.1 Lux/F1.2, B/W: 0.01 Lux/F1.2 Note you can see the Microseven on the barn has already flipped to night mode.
Flipped to B/W at 17:51:23
Lastly an Amcrest IP3M-956 rated at 0.1Lux /F2.0 (Color)
Flipped last at 17:54:25
After dark things were not much better. Though part of the problem here is the GW cam is smaller so sees the wall and AC unit that the Amcrest, right next to it, does not.

IP3M-956 at midnight. Note the dome is already dirty again so there is glare.
In the daytime it looks about as good as the Amcrest despite being a lower rez. Note it is only speced as 100 degree view angle. You can see here the GW cam is about the same view angle so not way it is 160 degree.
IP3M-956 about noon
GW5747MIC about noon

I've decided to move all the dome cams inside since they get dirty and pick up reflections real quick (see pic above) so I moved the GW5747MIC to the garage to replace the Foscam FI9828P. The GW5747MIC does have better night vision than the Foscam on top of better rez and view angle. The GW5747MIC can monitor almost the whole garage at the same level of detail without the need for pan and tilt. Though the Foscam can still zoom into get a bit better shot if you are watching and can center and zoom quick enough to get the shot. All in all it seems like a pretty good fit for the garage though realistically I doubt I'd buy another one if this one went out or I need a cam for a similar area.

First though I noticed the diff between the top two rez settings seems to be that is stretches the picture vertically. You will notice here that both show the same amount of the garage. Yes I know it is a mess. Note is a two car garage though it looks more like a 1 1/2 in the pics.

When I turn off the over head light and just have the opener light on the Foscam has to go into night mode though the GW5747MIC does not even in the default Auto switching mode.

Lastly compare shots with all lights off.

Note you can stretch the flip to night mode some more by switching from Auto to Auto(inter sync) though you will some more graininess during the extended color period. adjust the sliders for the right compromise between seeing color and grain.

This is about the max you can push the flip. With THR. of day much lower it will flip back and forth.
Update: Notice something else today. After upgrading my router to one I could turn IPS on without cooking it I discovered this camera is making DNS requests to several sites around the world. Not that I let DNS requests go anywhere from my IoT networks except to my local DNS servers. A quick google shows this is not a new thing with them.
