Ring Video Doorbell Wired

Although it resembles a standard doorbell, the Ring Video Doorbell Wired is super-powered. This smart doorbell that can provide you with a 24/7 video stream and a nice wide field of view (up to 155 degrees horizontal and 90 degrees vertical) — meaning you can see a broad swath of your property and any activity that might be occurring. The device syncs to your smartphone, tablet, laptop or streaming device (it’s easy — there’s a Ring app), so you can keep an eye on your home whether you’re inside, at work or away on that big summer vacation you’re planning. And this is the exact right moment to snap one up. For Prime members only, the Ring Video Doorbell Wired is down from $60 to just $45.

"I absolutely love this doorbell. I’m thrilled the doorbell doesn’t need batteries. I hated that," said a five-star reviewer. "The setup is so easy and the doorbell notifications come through my phone and my Alexa Echo Dot...Plus the quality of the sound from outside is really good too.... I would absolutely purchase this particular Ring doorbell again."

The Ring Video Doorbell Wired is hardwired (hence the name) into your home’s electric system, so there’s no need to worry about replacing batteries every few months. As long as there’s electricity flowing through your home, this guy is on the job.

Ring Stick Up Cam

Down from $100 to just $75, the Ring Stick Up Cam is an all-weather camera that connects to your smartphone, tablet or laptop via the Ring app. It's happy outdoors or in and can stand on its own or mounted on a wall (adhesives and mounting brackets are included0. Setup on your phone takes minutes, leaving you with an instant feed — and an eye on your belongings —whenever you want. Image quality is stellar, and battery life is up to four weeks per charge.

"All I can say is wow," raved a delighted five-star reviewer. "Bought this camera, as we believe someone is scaring our dog while she is outside...and it's been a total game-changer. We have the doorbell one out front and this security cam out back of our townhome. The picture quality both day and night is superior.... I'm super impressed with the night vision and am also loving the much larger battery, which is lasting way longer. The videos are crystal clear and would have no issues catching anyone causing problems..."

The Ring Stick Up Cam features a sophisticated motion detection and night vision system that notifies you when triggered. It even has two-way talk, so you can, say, ask the delivery person to leave your package around back right from your phone — while you're in the basement elbow-deep in laundry!

Ring Spotlight Cam

On sale for $150 (was $200), the outdoor Ring Spotlight Cam comes with a mounting bracket and installation tools and will stand up to wind, rain, snow and more. After installing the cam (shoppers say it's a breeze), just connect it to your smartphone, tablet or laptop via the Ring app for an instant live stream with sharp and clear Full HD video quality at 1080p via Wi-Fi.

"...The unit was up and running within minutes," raved a delighted five-star reviewer. "It has a very sharp, clear picture and picks up every movement...We have two Maltese and they are constantly barking at the door as if they hear someone outside, so it’s good to have the camera to validate if they do...I also like how it will alert you when motion is detected. I can be in parts of my house and not hear the doorbell, so it’s great to know when someone comes by or drops off a package."

Ring Alarm 5-piece kit

On sale for $120 (was $200), the Ring Alarm Kit includes a base station that works as a hub for your smartphone and security system, a motion detector for indoor and outdoor use, a range extender to widen your Wi-Fi network’s reach, a keypad to arm and disarm the system, and one contact sensor for windows and doors. This smart-home security kit is ideal for apartments and condos. And shoppers love that the kit is easy to put together.

"The system is really easy to install," raved a delighted five-star reviewer. "The sensors are already registered with the base station so you just need to stick them where you need to and you’re good to go. Make sure you are sticking them at the right place, You can’t reposition then and they won’t stick again with the same strips. The monitoring is really good..."

Ring Alarm 8-piece kit

Have a bigger home? The Ring Alarm 8-piece kit works best for homes with one or two bedroom homes. It comes with everything that the 5-pieces includes — one base station, one keypad, one motion detector and one range extender — but comes with four contact sensors instead of one. And shoppers like that you can easily add more Ring devices to the alarm kit without skipping a beat.

"Amazing alarm system! The product is amazing and very easy to set up right of out the box," shared a satisfied Amazon shopper. "I already have Ring cameras around my house and the alarm system is just like the icing on the cake! Everything was already paired and just had to set it up where I wanted. The base is loud and the sensors work great!"

And for an additional $10 per month for Ring Protect Plus, Ring offers an optional 24/7 professional home monitoring service. You’ll get unlimited video recording as well as instant access to your local police department, ambulance services and fire department.
