Following the request of a member, here are a few words about the Atz-dbv01p that I have bought from aliexpress : http://fr.aliexpress.com/item/ATZ-DBV01 ... 94912.html
I use it with RJ45 wire because, I'm not confident to use it with the wifi (possible with PowerOverEthernet to avoid an 12v supplementary wire) With a quick test it seems to need to be very close with the WifiBox (<7m ? But I need to test again to be sure.)
So with the ATZ in Ethernet and the phone in 4G :
Pro :
- Very good Video Quality, even in HD. (in fact you have 3 quality SD, LD, HD).
- Very good audio quality. And it's Full duplex.
- The iphone Apps is very good too. In 1 month, I had 3 updates of bug fix.
- Configuration is very easy. This is unbelievable. power it up on you network. Install the app on your phone. Register yourself. Ring the bell and TADA ! You get a notification on your phone on 4G, at work. This is magic. No network configuration needed. (I have a dynamic IP at home, Firewall...) That mean that probably the video Bell use a technic called reverse proxy and must declare itself on a central serveur (in china ?). Same thing than TeamViewer if you know it.
Con:
- At ATZ side, there is a constant background noise, like a little blow of wind. Nothing important, but it make me crazy to think that it consumes power. Even if it is not much. The atz support team that I have contacted about this, said it's 2 to 3 Watt consumption only.
- The 433Mhz chime is not "detected" by RFXCOM. A big disappointment for me.
- And up today, there is nothing to comand it easily. (I planned to command by domoticz the relay for example). I ask the support about an API, and in return, they send me a very gentle 100Mo tar.gz file !!! All the source code and documentation of their iphone and android apps. All in chinese !!! Not a word of english !
In conclusion : An IP video Door Bell. Yes ! It's brilliant ! But this one , I don't know... I have no comparaison.
And I send an SOS ! Did there a chinese reader around here ? If so, I would make a deal : translation in exchange of developpement
