security systems minnesota

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.

You hqve a good point here. For security cameras yes anyone can do it. For alarm systems where is involved lives, I am 100% people we love to know every thing works fine and it will be working agter is installed it, also people forgot the liability point of view of insurance. If you install by your self a new set of brakes in your vehicle to save some dollars and you got an accident and the accident was on investigations and show at the end it was because you forget to place the safetu device and the insurance found this issue and ask where you do your breaks so we can go and claim every thing we are paying to you…you will say, I did it by my self. Where you thing the investigations and suspicious will go. More and more people install alarms system by it self and more and more you see them in courts defendant their self from insurance claim they did it in porpuse, insurance think they did that wrong to claim millions.
