Top 5 star

After installation of this lens you can see at last the room properly. Have a HooToo camera for surveillance in use. Room size approx 30m2. Before you could see only the entrance door and now indeed the entire room. Toll. For installation. The installation has to be done very easily and effortlessly. The old focus ring with the old lens unscrew. Both for 10 minutes in the freezer. The focus ring was pressed with me on the lens. Trashed heat the focus ring with a hair dryer, so it widens a little. After that, the old lens are easily pushed out and the new lens can be used. Please do not push to the limit, otherwise no further focusing is possible. I first screwed the new lens and focused. Then the focus ring reheated and then placed him. Once it has cooled, it sits firmly back on the lens.

Great part, and unverzichbar for this camera. The night vision is guaranteed, of course, the edges are not completely illuminated. Those who want to can indeed buy IR emitters from the accessories, which are, however, considerably more expensive than the camera itself.

For me, absolutely adequate camera, plus now this lens. And top in price
