A:Answer To answer your questions. #1, You mention turning on/off the motion sensor. You can turn on/off the motion lights at a predetermined time frame which is what I think you mean, however you can't turn on/off the motion sensor. i.e. I leave at 3am most mornings and have the light come on prior, so I don't have to back out unto a dark driveway.
#2 Ring has implemented playing different sounds through their RING Chime (Pro) unit which helps play during ring/motion events. They do not have a way to record your own sounds at this time, however they are always implementing new features. i.e. We had halloween sounds at our frontdoor and now have turkey's gobbling for thanksgiving.
#3Once you SYNC the RING devices to your WIFI network via the RING app, all the IP Forwarding/DNS setup is done automatically and will work for you no matter
if your at home or away. Call it PLUG and PLAY at it's best! You do not have to worry about all those confusing setup procedures.
RING has excellent customer service and HELLOTECH is the premier installer for RING products and can have a tech do it for you for $50.
