I purchased 4x 4k hikvision turret camera and nvr system from use-ip, and I have to say the cameras are brilliant plus the service is second to none Another good feature to this company is the aftercare are you can ask their support team any questions about your system and they will do whatever it takes to answer your question The support team has so much knowledge it's unbelievable So if you're not a professional in the CCTV business you have no fear in getting your questions answered I would definitely buy again from this company and I also recommended a friend and he bought a full cctv system as well Thanks use-ip
