Greensite Client Testimonials
What a Great Company. They did work on my restaurant installing cameras, Very professional, great service.Stoney Brook Grille
If we could give more stars we would! The cameras we had installed by greensite have been a lifesaver especially when I’m away from home. Was to able make sure the kids didn’t party while we were away and that my house would be just as we left it when we came back. Thanks for giving me peace of mind greensite! You’re the best!!Christine S.
Last spring we were interested in getting a camera system installed. We decided to go with Green Site Group and were very satisfied. Two days ago our cameras came in handy, our UPS guy broke our Christmas light show that was on our lawn (which we only had for 3 weeks). The first thing UPS said was if we had video of it, right away my husband said YES I DO. They were speechless. They put in a claim to the insurance company, the next day the insurance company called and said that we didn’t need to send them a copy of the video because they spoke to the driver and he confessed. They’re reimbursing us the full amount of the item. If we didn’t have our camera system I doubt the outcome of this situation would of been a happy one. Thank you Green Site Group for our AWESOME camera system!!! I HIGHLY recommend a camera system and THIS company. Thanks Mike!!!!!Nicole F.

GreenSite security has been monitoring our home for years. They have always provided exceptional service with the most courteous and professional technicians. We recently installed a pool and felt that we needed cameras for extra security and piece of mind. GreenSite came to our home and not only did they install A top of the line security system at an affordable cost but their professionalism is beyond compare! Im extremely satisfied!Judy H.
Mike and his team very recently did an install at my office at Overview Computer Services in Uniondale NY. The system works better than I could have ever expected and solves security issues that have plagued me for years. I’ve worked with Mike for a few years now and I can attest for his professionalism and attention to detail. They are a rarity in the security business, which is full of fly-by-night companies of ill repute. His team is solid and in his last 13+ years in the business has made solid choices in his employees and business associates. I would recommend GreenSite to any of my friends and family.Overview Computer Services
