I'm a building manager in a 55 unit west LA Apartment complex. We have had 3 robberies in the past 2 months. The residents were getting scared and the police suggested we install a video Security System. Not knowing much about it, I contacted video security systems los angeles, and they helped in getting 2 of the most pleasurable sales people to help explain what we need. Fast forward 1 month and we just installed the system. Wouldn't you know the very next night a robbery took place in the building. This time we had the criminals on tape and was able to share it with the police. The police actually recognized them as perpetual burglars in the area and now had the poof to arrest them.Wow, is all i can say.
