I bought 2 Hikvision turret cameras with an NVR. During my renovation I took into account where the cameras would be placed. So connecting was quite easy. Drill holes, screw in and insert UTP cable. Installation was quite easy. I ended up having some questions about certain settings and definitions of terms. (Tip chatgpt also works well). Alarma Total supports you with questions. They are accessible and provide quick answers. All in all I am very happy with my purchase. Purchasing quality safety products from a quality store is the safest thing you can do!
