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. VCR technology became available in the 1970s, making it easier to record and erase information, and the use of video surveillance became more common. Closed circuit television was used as a form of pay per view theatre television for sports such as professional boxing and professional wrestling, and from 1964 through 1970, the Indianapolis 500 automobile race. Boxing telecasts were broadcast live to a select number of venues, mostly theaters, where viewers paid for tickets to watch the fight live. The first fight with a closed circuit telecast was Joe Louis vs. Joe Walcott in 1948. Closed circuit telecasts peaked in popularity with Muhammad Ali in the 1960s and 1970s, with "The Rumble in the Jungle" fight drawing 50 million CCTV viewers worldwide in 1974, and the "Thrilla in Manila" drawing 100 million CCTV viewers worldwide in 1975.

This smoke alarm is only one piece of Nest’s larger home automation system. Not only can you network multiple Nest Protect units together, but you can also connect other Nest devices such as thermostats and security cameras. Additionally, the Nest Protect is compatible with other smart home networks including Nexia, Vera, Wink and Google Home; it doesn't work with Amazon Alexa or Apple HomeKit. Unfortunately, the two year warranty is shorter than those from First Alert and Kidde.

It also uses voice notifications to let you know when you need to change the battery. If you buy more than one of these detectors – and you should!– you can network them through your home’s Wi Fi network. Once they are connected to the internet, you can download the Wink smart home app to control your smoke detectors, as well as many other devices, remotely.
