Nelly's H-Series IP Cameras - HikVision ColorVu

Quick starts

Videos in the Hikvision and Color night vision playlists

The version I have here is the OEM version of the DS-2CD2347G1-LU from Nelly's Security. Note there is a DS-2CD2347G1-L that appears to be the same thing without audio for about the same price from most sellers. There is a 2.8mm version just listed on Amazon that I ordered.

First thing you should not is the cams come with a static IP set of 192.168.1.64. This means you either need to have a 192.168.1.X network or a Windows PC you can run their tool on.

Next these are huge.
Here is the HikVision turret model (left) next the the Amcrest (right).
If you look close you will notice UP is marked on the case. A nice feature. I usually end up drawing an line on these so I know which way is up out in the field.

To install an SD card (128GB max) or adjust the rotation of the camera takes an Torx-10 screwdriver. Though realistically if you are going to be doing this kind of stuff you should just break down and get driver and set of bits that include straight, Phillips, hex and Torx bits of various sizes. Maybe even an all in set.
Update I found the L shaped Torx it comes with under the packing so you don't need to get one though having a set with screwdriver like grips might make you life easier.

For a quick test I just swapped in place of the west Amcrest skycam. The difference was amazing. For this compare shot I set them all to an exposure of 1/12 and gain of 0-100.

The original Amcrest is lower left, the Dahua upper left and the HikVision on the right.
Now this how sensitive the HikVision is. Here I set the Amcrest and Dahua exposure to 1/3 which causes ghosting see this video,  but the HikVision is at 1/30 (double the frame rate).

You can also compare the above Amcrest 1/3 exposure video to this 1/12 exposure video from the HikVision and this Dahua one.

Here is the odd thing. It actually looks darker during the day which is why I did the above video with exposure 1/12. For example here is the next day.

The Amcrest and Dahua are using profile scheduling to switch to automatic exposure for the daytime. The HikVision is still set to exposure 1/30 (it does not have an automatic setting).  It does have profile scheduling but it would appear to be unneeded so far. I checked to make sure it was not switching the exposure based on profile.

Though if you are looking to grab hummingbird stills from the video it appears switching to 1/100000 is doable even on an overcast day like today.

Three days later and an even tougher test. While the moon is technically up you can not tell where the clouds are so thick. Not just dark but but air so heavy with moisture it is almost fog.
Here the old cams are set on auto but and the HikVision is still has exposure set to 1/12
The original Amcrest is lower left, the Dahua upper left and the HikVision on the right.
Cranking the old cams down to an exposure of 1/3 it looks better.
The original Amcrest is lower left, the Dahua upper left and the HikVision on the right.
Turning on the back door light ~45 feet from the barn in the picture with the old cams still at 1/3.
