Bought them to get some security coverage for the front and rear of the house. Picked this instead of Video 2 doorbell for the front as I preferred the features and video quality of these cams better. Setup was a 5 min job. Picture clarity is decent, its a clear view if someone is in close proximity. Can't expect it to track vehicle rego numbers on the street if its mounted on the porch. Light and siren is quite strong. Make sure you have good Wifi reception where you are mounting. Recommend the wired version over battery. Proximity sensor triggers and proximity lights work really well. Siren is quite loud and will attract attention. The remote speaker's audio quality isn't the best, you can have a conversation, but some words sound muffled.
