A lot of value for good price.Had one problem setting up email alerts through the NVR, but Haris at Amcrest's tech support got me through it. Gmail consistently failed, but yahoo worked first try.

Excelente compra!!! Qualidade de câmera incrível! Câmera super leve, bem intuitivanas intruções sobre o que vc quer fazer com ela! Amei!

This was our 3rd of these, use them to keep an eye on the dogs at home while I'm at work. I keep the Amcrest app up on a cheap android phone at work all day under my computer monitor and typically don't have any issues. Works great for what we need it for. The 3 cams are typically off-sync by a second or two, but not a big deal. There's also a little lag with mic/speaker, but also not a big deal for us. We bought the cameras one at a time over the course of about 1.5 years, so we're definitely a fan since we keep buying!

Very balanced sound with bass, middle and treble ranges good. The app also allows for enhanced bass or treble but to date not needed. Sound cancellation is good and easy to control.
