I bought this update security camera system for my store month ago. I installed it right away,after 2-days great shipping speed! I am not a professional installer, however I did install my 8 Chanel camera system and am very glad I suggested the Heimvision system! It'a very easy to install and set up. The video quality is great. The images of video taken during the day and night are both very cleaer. It comes with 4 hd camra heads and a lovely monitor. The mobile app is very convenient, I can watch everything in my home remotely, anytime, anywhere. I also installed two heads out front of the store. Don't need to worry about in the rain or snow cause they waterproof. Since i had them around my store i haven't lost any package in past month. As a small business owner i think it works perfect for me. Anywag This system is outstanding. Great price and Amazing product!
