Hello all. I am new here and expecting some help from experience guys. I got a AHD DVR from DKPlus I think its china made the board/ Main Processor they used is Grain Media's GM8283. Now I want to know that can I use some other DVR's Firmware as I dont like its firmware and sometimes its lagging a lot or getting hanged/stuck and then have to restart. I tried 3 same DVRs with same firmware all have same problem. please guide me about installing a good firmware on this DVR. Regards.

Hello, I am thinking to buy and install hikvision ds-2ce16d1t-ir and hikvision ds-2ce16d0t-ir. both are 1080p cameras. Just want to know are these good cameras for outdoor (lawn, roof top)? and which Hikvision 1080p DVR will be good? I watched some videos of these cameras on youtube so the result will be same like that or not ? please help me. thanks in advance
