Review on Amcrest Security Dual Band 4 Megapixel IP4M 1051W by Paul Stocks

I bought this camera for my business to use as a security camera. I have two other Amcrest cameras, both IMP3. This one seems to be better with its responsiveness as well as a sharper image. Recently my internet switched to a frequency other than the usual 2.4 or 5 GHz and my other two cameras were unable to transmit data on it. However, this one still works with this new network, which saves me. The mic picks up sound well, but the speaker (speaking from my phone to the camera) isn't very loud (especially not for a shop, might be better for home use there). Overall I highly recommend the camera and will buy from Amcrest again if I need a new one.
