The smart home security cameras of CES 2019

Alarm.com's Wellcam home security camera is designed to help caregivers, family and friends watch over aging loved ones remotely. 

The Wellcam has a 180-degree lens, two-way audio and 1080p HD resolution. Press the "call-out button" on the Wellcam to ask for help without a phone.

The Altro Smart Lock is part lock, part smart security camera. It has two-way audio, costs $350 and starts shipping in January. 

Arlo introduced its Ultra cam back in November, but the company announced at CES 2019 that the Ultra is now available for purchase. 

Brinno Duo Smart Peephole DoorCam replaces your peephole to monitor your front door.

Deep Sentinel's Smart Home Surveillance System is a professional security service. 

It includes a monthly fee and access to "remote surveillance guards" who are supposed to monitor your house and even speak to a potential intruder via the camera's two-way intercom.

Elecpro's US:E Smart Lock isn't like your standard deadbolt. the US:E has a built-in camera with facial recognition. 

The idea is that you'd create a database of familiar faces -- friends, family, caregivers -- and the lock could scan their face and then unlock the door. 

Unlike many smart buzzers, the Ezviz DB1 Video Doorbell has a built-in microSD card slot. It also offers optional cloud video storage. 

The Onelink Bell is designed to work with other First Alert products. It has:

• 1080p HD resolution
  
• 180-degree lens
  
• Night vision
  
• Two-way audio

LifeShield's Doorbell Camera has 1080p HD resolution, night vision, two-way audio, motion detection and cloud storage. It can be hardwired or run via battery.

It should be available starting in the second quarter of this year.

The Maximus Answer is a bit different than the other smart doorbells we've come across. It actually has two built-in cameras -- rather than just one. 

Use the front-facing camera to see who's at the door and the bottom-mounted camera to keep an eye on packages. 

Netatmo's Smart Video Doorbell is supposed to work with Apple HomeKit. That should mean you can manage your doorbell settings in Apple's Home app for iOS devices, as well as use Siri commands.

The Ooma Smart Cam can go inside or outside. It's battery powered and has facial recognition capabilities.

The DoorCam 2 by Remo+ is the company's next-gen over-the-door security camera. It relies on batteries and is supposed to fit over your door for a installation that doesn't require electrical wiring. 

Remo+ had the RemoBell W on display at CES 2019 as well. This hardwired buzzer has live streaming, motion detection and other standard smart doorbell features.

Remo+ also had the RemoBell S on display at CES 2019. This is a hardwired buzzer that replaces an existing wired doorbell.

The Door View Cam is Ring's latest smart buzzer. Rather than replacing an existing hardwired doorbell, the Door View Cam replaces an existing peephole. 

Home security camera SimCam is another new camera at CES. It can rotate 360 degrees, has night vision and works with Amazon Alexa and Google Assistant.

SimCam also has facial recognition tech and claims a "99.4 percent accuracy." 

TP-Link also has a new indoor camera, the Smart Spot. 

The Smart Spot has 1080p HD live streaming, a 130-degree lens, two-way audio and night vision.

The Kasa Smart Video Doorbell by TP-Link has facial recognition and two-day free cloud video history. Upgrade your cloud storage with a Kasa Care subscription.

The Smart Wire-Free Outdoor Security Camera System runs via rechargeable battery. You can buy it as a single camera, as well as in two- and three-packs. 

The camera comes with a hub, has 1080p HD live streaming, night vision and two-way audio.

Tuya Smart has a home security system on display at CES. Part of it includes a connected doorbell. Tuya Smart says the buzzer has facial recognition tech that lets you know who's at the door.
