I think the last time to buy the NVR company which is really good, now every meeting, as long as they use the NVR, they will say that the NVR is very good, the NVR than before the better, hear what they say, I is really very happy. This NVR is for me to buy, buy to let everyone satisfied well before that, a few days ago, said the leadership is to allow me to buy a new NVR, I went to a very good store to buy NVR, I bought this NVR not only quality good, and the price is very cheap, so I think to buy this NVR is really very good, if you don’t believe me, can also buy such a try with NVR.
