Other features to look for include face recognition technology that identifies visitors by name, motion sensing technology that knows the difference between people, cars, and animals, color night vision video (most doorbell cameras use infrared LEDs to provide up to 30 feet of black-and-white video), and a choice of chimes that will help you differentiate between a doorbell press and a motion trigger. Some of latest doorbell cameras offer a pre-buffer feature that records several seconds of activity prior to when a motion sensor is triggered or the doorbell button has been pressed so you can see what happened just before an event.
Many home security systems offer video doorbells as add-on components, but these devices typically do not work on their own and must be connected to a system hub. However, they usually interact with other system components such as door locks, sirens, and lighting. If you want a standalone smart doorbell that will work with other smart devices in your home, look for one that supports the IFTTT (If This Then That) internet service. With IFTTT you can easily create mini programs, called applets, that let IFTTT-enabled devices interact with each other. For example, you can create an applet that tells a Wemo Smart Switch to turn on when a Ring Doorbell is pressed, or have a D-Link siren sound when an August Doorbell Cam senses motion.

The Booming Video


Splice is a video editor from GoPro, the company behind some of the world’s best action cameras. You can import your photos and videos into the app, to edit them into a movie. The way the app works is simple: you just import the videos that you want to edit, and mark the important parts (Hilights, as the app calls them) of the video. You can then add music to the video, and then the app automatically clips the entire video according to the Hilights that you marked.

8 World-Class Video App Businesses


Nothing makes an impression like moving pictures with sound. That's why digital video continues to grow in importance online. Couple that trend with the ever-increasing availability of devices capable of high-resolution video recording—phones, GoPros, DSLRs—and the case for ever-more powerful video editing software becomes clear. Further, the software must be usable by nonprofessionals, and it has to keep up with newer formats such as HEVC (High Efficiency Video Coding) and 360-degree VR video, and it has to be able to handle 4K and higher resolution.
Signal Private Messenger is one of the most popular privacy chat apps. It features end-to-end encryption for all messages, voice calls, and video chats between two Signal users. It focuses a lot on individual chats. There are group chat features, but it's mostly for personal use. This is one of the biggest differences between it and rival privacy chat app Telegram. Video calls worked fine in our testing so we have no trouble recommending them. It's a neat way to get some encrypted chats as well. The app is also completely free and open source. You can't really go wrong with it, but there are better video chat apps if you need group video chats.
