I'm new to this forum but have already received great camera recommendations for my backyard. Anyway I've been using a GBF PL960M WIFI IP Doorbell
GBF PL960M WiFi IP Doorbell with Remote Access by iOS and Android Smart Devices | GBF electronics Inc for about 8 months now and been very satisfied with it. I actually bought it off Amazon not from GBF website. From what I understand GBF is located in Canada but the company itself is Chinese.
When I purchased the PL960M the only other product in their line was the PL961QPM but they've added a whole slew of new products since then. Heck the PoE adapter wasn't even available at that time so I had to have an AC outlet ran in order to power it. The doorbell supports both WiFi, Ethernet, 2-way live video and audio monitoring, motion sensor, and can trigger a remote door lock or gate... it does not include cloud recording. It has a very robust build with an industrial look.
Tech support is great, software is ok and can probably be tweaked if you know what you are doing (I don't), the app itself I feel is a little sparse/clunky. I just started using
Blue Iris which it supports so that's a much better setup along with the BI app. For doorbell alerts (someone pressing doorbell button) you get an alert on the GBF app to either accept (allows 2-way communication) or deny (don't want to talk). I don't know if the BI software/app could be configured to do this totally eliminating the GBF app... that's a little over my head.
I'm not the most qualified to judge the video but to me it seems plenty good for a doorbell camera. Your video standards on this forum are much higher than mine so please be your own judge.
