Hey guys,
Just want to throw a few cents into the discussion on this DB1C, based on my readings and new experience.
At first, I was getting slow connection, choppy playback through live view and recordings through BI (and even in the ezviz app), but VLC seemed pretty stable. Other weird issues with frame rate and iframes, and errors in the log, and deepstack was detecting me holding a baseball glove for some reason lol! So I thought it was the system I installed it on, so I did a complete reinstall of Windows 10, and uninstalled all useless programs (ie. onedrive, etc), to then set up BI from scratch on a clean system.
In the mean time, as I was cleaning up that system, I was exploring my wifi coverage after reading that people were having a lot of network issues with doorbell cams. Yes, my DB1C was getting very low signal from the start (that little wifi logo only had 1 small bar). Using a signal scanner app on my iphone, I could see that just outside the front door my signal was averaging -75dbm; and I thought this might be my real problem.
And it was. My wifi router is located at the other end of my house opposite the doorbell cam. A wifi extender solved the issue. They're only about $40, you don't need a fancy one, or do what I did and repurpose an old router with dd-wrt firmware and set that up as a wireless repeater. I placed it just inside the front door hidden under some stairs, and now I have on average -30dbm with full signal bars. The performance is +500%. When I load up live view, it goes from 0% to live almost instantly and no choppiness at all. This was in the ezviz app, btw, I hadn't yet fired up the BI system, but I will be tonight.
One more thing I recommend to anyone just starting out with BI is to read the * manual. I know it's over 200 pages, but a lot can be skipped. There is so much good info in that document; most questions I see asked on forums are answered in there already. I've decided to read the whole thing (I'm already over 1/2 way through and will finish tonight) before adding my cameras to BI. I've already learned a few tricks not seen on those quick and dirty youtube tutorials, and already have a better understanding on how the software package operates as a whole.
tl;dr:
DB1C is a great doorbell cam, just make sure to give it good signal, either move your router closer or use a wifi extender. Apple airport app using wifi scan mode is actually quite useful for testing signal. And as always, rtfm.
Cheers all!
