Jammers.

I was away from home for 10 days with my Telus app on away. Yet when I returned I found the grouts in my bathroom dirty when I had left them chloroxed and when I went to vacuum 2 days later Oct 19th, the cannister was filled with dog hair when my dog was groomed in September. Can people with jammers bypass home security? How can I check activity Oct 6 to 17?
