Welcome to my blog! My name is Lu. I used to work selling security systems to families. However, I noticed that our system wasn't necessarily the best option for some families, and once I left that job, I started studying security systems. My goals was to help friends: some were renters, others were elders and still others fell into a range of other categories. Ultimately, I wanted to create security set-ups that worked for a range of situations beyond the classic single family home. This blog is the culmination of my research, and it purports to look at security from a rang of angles. I hope that these posts help you. Thanks for reading!
