The camera presents a good daylight picture. Facial recognition at 50 feet is possible in full screen mode. Night time pictures are dark and grainy. Beyond about 60 feet motion is about all that can be seen. If you need to see beyond 50 or 60 feet at night, go to the higher priced camera. I can't rate the audio because I don't use it. I am somewhat disappointed, but, you get what you pay for.
MCM is a great company. Very fast service and shipping of Raspberry Pi. Will tell all my friends to buy from MCM
