I compared the Z4, Z12 and a PTZ for identify at 60 feet in this video. They are all good choices but I would go with the Z4 if I had to pick one.
Side-by-side comparison of Dahua Z4, Z12, mini PTZ and a Reolink.

This is an industrial sensor, so you'll have to make sure to get the voltages correct and have soldering skills to deal with it. Yes, ESPHome. I had to build a...
I have 3 pairs of those sensors outside. No issues. I put a piece of electrical tape around the seam between the plastic shells so there is no path for water to force it's way in.
1 pair in direct rain for 5 years.
1 pair partially covered but still gets wet in heavy rain
Last pair mostly...
I finally got a 3D printer and printed a bracket for the birdhouse. I designed the model in the free Tinkercad web app, and printed about 5 or 6 prototypes before I got it right.
I use cheap beam sensors that only have a single beam, but they are surprisingly reliable. Sometimes a bird will fly through them so I filter that out with ESPHome requiring at least 200ms break, or in combination with a PIR sensor which doesn't pick up birds...
Yes it's just sitting loose in the birdhouse, and the bottom of the camera is rounded so wobbles out of position if I mess with the wiring at all (I also ran 16 gauge landscape power wire for motion sensors, possibly lights, which I am still setting up). I need to 3D print a base because the...
I ran PVC conduit for a tree camera's ethernet cable, but the conduit was an eye sore. Too industrial looking. The conduit looks much better after painting it with tree-color-matched paint and wrapping it in fake ivy. I'm curious what other ideas people have tried for concealing conduit...
I agree the test is problematic. It was just an idea I had right before uninstalling the 2 cameras and replacing them, why not compare how all 4 perform at identification. The Reolink doesn’t belong, but 3-up doesn’t fit nicely in a comparison and I figured this audience would enjoy the Reolink...
I did a night test with a running subject. There was a lot of extra IR light since all cameras' illuminators were on at the same time. I was expecting the Z12 to look the best, but I think I prefer the Z4, because I can see much more of the surrounding area and the subject's full body, with...
Yes, Z4 and Z12 are at max zoom. I will set separate exposure settings for day and night, either manual or shutter priority to ensure there is no blur as there are fast moving joggers and bicycles on the trail. For the comparison I figured it would be fair to leave them on auto.
Here is a side-by-side comparison between the popular Dahua Z12 and Z4 varifocal cameras, Dahua's new SD4A425DB mini PTZ, and a 4k Reolink. I will use the Z12 and the auto-tracking PTZ to watch the public walking trail next to my yard, and move the Z4 and Reolink elsewhere, but while all four...
This site motivated me to get a license plate cam, but I'm worried that lightning could strike the tree in my front yard and follow the LPR cam's ethernet cable inside to fry my entire network. I'm using a Ubiquiti ETH-SP-G2 ethernet surge protector, but I read that nothing can stop a direct...
I had trouble getting license plate reader to work on GPU until I downgraded my version of Cuda Toolkit from 12 to 11.8. Download previous versions here: CUDA Toolkit Archive
The logs show triggers coming in even when alerts are not created. The PC is at 25% load or less. Would you mind changing one of your cameras to have a 10s trigger time and reproducing this issue by triggering the camera over and over?
Raspberry Pi that displays UI3. You can configure the Pi to open UI3 full screen on startup so it works as a nice little dedicated Blue Iris viewer. I power my Pi 3 with a PoE to USB adapter to cut down on wiring.
If I right click on a camera and click "Trigger Now", wait for the trigger to end, then click "Trigger now" again, an alert is not generated after about 5 triggers in a row. Can anyone else replicate this behavior?
As a test, I set "End trigger unless re-triggered within" to 10 seconds...
The NC400’s firmware is C-R-E7-0. Its model I81HC which the OP describes as using a specialized firmware so I haven’t tried updating it because I don’t have a backup of the original firmware if I need to revert. Edit: I tried updating the NC400 but the Hikvision ClientDemo tool gave me error...
I updated an NC800 with IPC_G5_EN_STD_5.7.1_211009
If I could do it again I would rather just by a Hikvision DS-2CD2387G2-LU which seems to be a similar if not same model but with a 3rd stream.
I haven't found a compatible Hikvision firmware for my NC400.
