Ring Doorbell V2 is smart security for every home. This doorbell takes your security to the next level – it allows you to monitor your door from anywhere in 1080p HD resolution using your mobile phone. In addition, thanks to the two-way audio (microphone and speaker), you can talk to your visitor without opening the door. All this using your mobile phone, tablet or computer. Of course, notifications are sent directly to your device in case of movement. The Ring Doorbell V2 has adjustable motion sensors with a range of up to 10 meters, thanks to which any movement in front of your entrance can be recorded. There is also infrared night vision. The package also includes a replaceable battery with a duration of 6-8 months of operation on a single charge.
