Security Camera in the Kingdomhall

I heard my husband and our elders in the congregation talking about something our kingdom hall's security system, that isn't working good at the back of our hall where usually they noticed some mark that some body trying to get in. Husband once found out that the door knob was loss and almost to pop out. Right away they decided to put a Surveillance Camera which is very secure way to monitor who's coming in and out in the vicinity not just the hall they wanted to get in also the parking cars. Since husband knows everything about electronics stuff he volunteer to install it. I'm glad he knows anything and everything!!
