This was the 3rd time we've used this company to install security cameras for us. This time it was for our office. They were great as always and very thorough. George and Joe are the best team. Georgie did our install this time and he was professional & 100%! Thanks again for the best service and installation!!

Video Surveillance — Repeat Customer
Prince is simply the best!!! did a great job installing five cameras for our home. fast, clean and a fair price. went over all of the operations, how to watch remotely, etc. then a few months later, we decided we needed a sixth camera. no problem, he came out and did the job quickly and perfectly. would recommend Oren to anybody needing great, friendly, professional service.

Video Surveillance
United Security Systems is extremely professional and efficient. They came to our house within a couple days of our initial contact, Price provided a quote within hours and scheduled our install just a few days later. The team was polite and moved quickly. We were home with a newborn during the install and they worked around us without any issues. Tyler spent at least an hour helping to set our phones and computers up and took extra time to make sure the camera angles and clarity were perfect. We highly recommend this company and are so glad we made the investment in our home security and peace of mind!
