Photo quality was drastically improved too true HD quality even with such a wide angle lens and colors are truly sharp regardless of night or day. The SkyBell HD app is a completely new app separate download in app store from the past models and is lightyears ahead and finally a “modern” app that works. We no longer worry about package thefts!Since installing the new HD model, I have had numerous conversations with neighbors through the SkyBell HD and I have even been able to tell solicitors to go away from my desk at work miles and miles away!Even better, I have been able to notify my neighbors when packages are delivered so they can pick them up while I am out of town. I love my SkyBell HD!I highly recommend this product. More detailed review below. HardwareFirst off, this device is sleek, nice looking, and ROCK SOLID.
