I work for a small company, with only 9 employees. However, due to rising crime in the area, we knew we needed a good camera system. We had a system professionally installed a few years ago that we paid over $5,000 for. It was constantly giving us trouble. Two of the cameras went out. And the system was not user-friendly. Every time we would have an issue, we would have to have the company techs come out to fix it and they would charge us a $75.00 fee for what most of the time was a five-minute fix but they wouldn't tell me how to fix it because they wanted to charge the $75.00 fee. When two of our cameras went out due to being struck by lightning, they charged $1500 to come out and replace those cameras. The camera quality on those was terrible. They were blurry and you could not focus on the images. We also couldn't get the images on our phones.When we were sick of pouring money out for this terrible system, we switched to the Blink cameras. They work very well with good video quality, but they are battery operated, and with as much movement as we have here on a daily basis, we were constantly having to replace batteries.I started researching and asking other small businesses in the area which system they used. Most of them suggested Night Owl, but after researching even more, I ran across this system due to a YouTube video. I read reviews, did a little more research, and found this was the best option for our application.The setup was super easy. I had all 8 cameras operational in less than 30 minutes. Installing the cameras was a little difficult because of the span we have between the cameras and the DVR. The package comes with 60' of cable per camera so if you are spanning more than that, keep in mind you will need more cable and connectors to bridge that cable. Once the cameras were installed and operational, they work GREAT! We are able to pull images up on our phones now as well as having a monitor to look at images and go back to a certain event. I'm so glad I made the choice to purchase this system and will probably be purchasing two additional systems for two additional locations we have in the area.
