So I'm currently on a short trip to Taiwan for New Years. Everything has been going good. One of the girls I'm seeing is crashing at my condo while I'm away as it is a more convenient location to stay for work and beats sharing her other space with her roomy. Today I get a message from her telling me some guy tried to get into my condo. Apparently he knocked and rang the bell a few times. She got up to see who it was and looked threw the peephole but said nothing. He stood there for a good minute or so and even tried the handle. My condo door directly faces the elevator lifts, so when some people came out he left. She told security downstairs and they have video, but frankly the security in my current building is fairly useless. It is a large place and lots of people are always coming and going. It is easy just to walk through the keycard door once someone else opens it. So, I'm considering beefing up the security of my door to prevent/deter douche***s from breaking in. What are my options and what would you suggest? I currently just have a normal locking handle, along with a chain lock on the back end. I'm thinking of installing an additional deadbolt lock. Anyone got experience here? My girl is a bit shook up about it and I don't really fancy some pleb trying to knock off my TV while I am out. Any help is appreciated.
