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. In 1985, the WrestleMania I professional wrestling show was seen by over one million viewers with this scheme. As late as 1996, the Julio César Chávez vs. Oscar De La Hoya boxing fight had 750,000 viewers.

This is free, no monthly charge. I don’t understand the reviews that say they are not recording videos when motion is triggered because mine do. Complain all you want but you won’t find a better deal with any other security camera. I’ll keep using my canaries for live views and motion triggered notifications and videos until this free service goes away. Then I’ll look into something like Nest, but hoping it won’t come to that. I usually don’t write reviews but this last update is really frustrating me. Been using the app for over a year, it’s usually been good but this last update July 2019 has made my cameras almost worthless as I can’t control them half the time anymore. It’s so buggy now like if I’m home for example and try to switch to night mode so I have them on when I go to bed, it just flickers the mode status icon and stays in home mode. LUCKILY the time schedule seems to still work so I use that to switch it right now but obviously you should be able to switch modes manually if you want like you used to. Also, over half the time now if I come home, it doesn’t switch to home mode anymore. If I open the app THEN quit and reopen it, it finally sees I’m home and shuts off the cameras.
