I bought a couple of HIKVISION DS-2CD2335FWD-I 2.8mm / 4mm, 3MP, Darkfighter, 30m IR, POE, IP 67 rated CCTV cameras for use with my Synology Nas drive (Surveillance Station). I had a couple of problems with that were solved very quickly by Jamils Holdings Limited. One was an issue with Synology not quite getting the latest H.265+ working with the camera but it's now on their to fix list. The other was with me not being able to find one of the cameras on the network which was solved by excellent technical support. I would definitely use them again as well price products plus great support (via email & via phone & texts) is all a customer could wish for. Well Done!
