I think it was a Sylvania product but it was a low rent security system. You set up a trip wire on a window or door to trigger a flashbulb which set off an audible alarm. https://www.freepatentsonline.com/3714647.html If you follow the pdf link it has a sketch of the flashbulb mount and string going over to a window. Best '70s tech. The company I worked for subcontracted for Sylvania and they had some strange products.
