As I expect from DB11 of Dahua. It's a great product and I recommend it strongly:
1. Sound is very clear to talk and listen: good intercom. Speaker is louder than Yosee.
2. Wifi signal strength is good and stable.
3. Image stream smoothly.
4. Color is acceptable.
5. It can add into NVR Dahua...

I not recommend this product because I installed a new one. But the quality video and and audio are very poor. Sound not clearly.
It can connect NVR of Dahua but the FPS not smoothly.
I search another product:
1. DAHUA DB11
2. HIKVISION DS-HD1
anh finally I order Dahua DB11. I will report when...
