A more advanced form of CCTV, utilizing digital video recorders DVRs, provides recording for possibly many years, with a variety of quality and performance options and extra features such as motion detection and email alerts. More recently, decentralized IP cameras, perhaps equipped with megapixel sensors, support recording directly to network attached storage devices, or internal flash for completely stand alone operation. The earliest video surveillance systems involved constant monitoring because there was no way to record and store information. The development of reel to reel media enabled the recording of surveillance footage. These systems required magnetic tapes to be changed manually, which was a time consuming, expensive and unreliable process, with the operator having to manually thread the tape from the tape reel through the recorder onto an empty take up reel. Due to these shortcomings, video surveillance was not widespread.

Next, I followed the instructions to set up the Chime: I scanned the code on the back of it, selected the room where it would be plugged in, and plugged it in it should be within 100 feet of the doorbell camera. Once I verified that the Chime was powered up, it was immediately paired to the doorbell and setup was complete. The August View Doorbell Camera captures sharp and colorful daytime video at 1440p, and the motion sensor does a fine job of detecting motion with very few false alerts. Setup is easy and you can have the doorbell work with August smart locks or trigger other smart home devices using IFTTT applets. That said, the View's inability to maintain a 2. 4GHz Wi Fi connection is troubling, and the iOS app needs tweaking. Until August gets these issues ironed out, the Ring Video Doorbell 2 is your best bet for a completely wireless smart doorbell. If you have existing doorbell wiring or don't mind running wire out to your door, check out our Editors' Choice, the Ring Video Doorbell Pro. It's a bit more expensive than the August View, but it supports Alexa and Google Assistant video streaming, and its monthly cloud service is more affordable. Be aware of everything that occurs on your doorstep with the doorbell camera. Receive push notifications on your mobile device anytime someone rings the bell and you’ll be able to view your live footage and communicate with whoever is there.
