Users review   

Fernando Villagers has opined that-

  • Perfect to work standalone, if you have a NAS or other network storage options, you can record the vision on it, and of course in the internal SD card.

Sandman from the USA says that-

  • I have 12 Hikvision cameras connected to a 16 channel Hikvision NVR. All of which were bought from an authorized dealer. IR cut filter jammed on one (mini dome model) after years so wanted to replace it. When comparing this camera and the box it came into all my others, I see nothing that indicates it’s not an authentic US model. Plugged it into my NVR and it auto-configured and started working instantly. Went into the DVR menu and set all my recording settings, and worked like expected. I have not tried updating firmware, but its current version is so new compared to my other cameras, I doubt I will ever mess with that.
  • I picked Vigilant Depot as the vendor. As for the camera itself, I prefer the Turret over the dome. They have a much better night vision range, and you don’t have to clean them that often. Anytime it rains hard, the domes get water spots that cause fuzziness while in night mode. The Turret does not have that issue.
