I did get one of these cameras, and indeed, I was able to set up its wireless IP address by first connecting it via ethernet. After setting up the wireless settings, I was then able to block it from accessing the internet using the parental controls in the router.
The router has a limit of 16 devices that can be restricted, which is disappointing, since one ends up with so many devices on a home network these days. So I freed up some capacity by installing a second ethernet port in the BI PC and putting a lot of my cams on that second subnet that has no direct access to the internet (the router can't see them).
The wireless cam must, of course be on the original subnet so the router's wifi can reach it, and I have a couple of other cameras whose POE switch is daisy chained off of a cable run and additional switch that must remain on the main subnet to accommodate some devices that require internet access (media PC, satellite TV box, etc.), and I didn't feel like running another ethernet cable to that point... yet.
So getting that camera did get me off my butt to set up the second ethernet network, which I've been needing to do for some time.
The camera works well, actually. I put it in my garage to start. The PTZ is nice. And even though the zoom is only digital, I'm actually a bit surprised that it can be useful, especially when viewing from a phone, when you just need some magnification on a small screen.
You can tell the camera is made by Dahua because the web server interface "site" looks very similar to other Dahuas.
I appreciate the recommendations from
@looney2ns and
@TonyR. It's a pretty neat camera for the price, especially with the promo code to get $10 off.
It's kind of nice to be able to just plop a cam somewhere to test locations without needing to run an ethernet cable to it.
It is powered by a 5V USB charger type supply, so it would be easy enough to use a 12V sealed lead acid battery and a car charger to temporarily fire it up at a location where I don't even have power.
Thanks, guys.
