Recently had high end security camera system installed by Josh and as a result of being very satisfied and appreciative of Josh's going the extra mile and doing quality, thorough work, I took time out of my very busy day to write this review. Josh had a lot going on that day with some very upsetting news during the install, yet he stayed focused on completing my extensive install thoroughly into the night hours. He takes pride in his work and is careful and methodical and high skilled at what he does. He was worth every penny. I would not have been able to come close to installing these camera's. He worked with me on the price and took my lower price range. I will be referring other friends who are getting camera's soon. The other reason I chose Smart Security is the online review and the fact they they are the authorized dealer/installer for HikVision, which is by far the best camera system out there for the money. They are 20 times better than their competition on many fronts. They are heads above the competition in terms of their investment in technology and R&D, camera innovation, features, software which is the most user friendly in the industry. They recently came out with their own version of the h.264 encoding/compression called h.264 Plus. It saves on bandwidth and HD space. I was very surprised and pleased at how well these IP camera's and NVR works. I recommend the 4mp, extreme IR turret camera's such as the one linked below.

I also have one vari-focus bullet camera for the mailbox across the street. I do recommend an additional IR Illuminator (CMVision) as most of these camera's just don't have the room for all the IR LED's. As soon as you get out past 30 feet, the picture qualify fades from lack of illumination for certain 30m IR camera's. When they say 30m, its actually about 20m of good picture quality. Some YouTube video's confirmed this for me.
