I am working on a large scale Municipal project involving 2000+ cameras. We are strongly considering 5200 due to the excellent feedback we have received from other localities and the engineering support behind Hikvision. We have deployed several of the higher end 128 channel machines with excellent results. Hikvision support for the products across the board has been 'remarkable'. We have deployed around 900+ IP cameras so far with '1' failure over the last 18 months. The technical support is first class, we have a local corporate tech in our immediate area to help the Integrator with any issues they cannot resolve. You can knock the Chinese all you want, there are some bad apples, but HIKVISION is not one of them.
