Must really say a top 1A doorbell, super video and picture quality and also the sound is top.
A small thing but to note, I have ordered the doorbell with 2 bells, the first sits quite na at the front door it rings, but the 2 bell in my study rings only as long as the doorbell is near, I stand in front of the front door rings the 2 bell no longer. So in the house the bells should not be too far away from the doorbell otherwise it does not work. But for this I have thank God still the cell phone in my study so I get with when someone rings!
Overall, but top satisfied, can only recommend the doorbell with camera! Just super!
