Hikvision 2MP 2.8mm Dome Camera | DS-2CD1121-1
The DS-2CD1121-I camera is dedicated for professional IP CCTV systems. The ceiling camera has been equipped with 2 MP 1/2.8" CMOS sensor providing good video coverage even in low-light conditions. Along with IR illuminator with range up to 30 m, the camera can also operate in complete darkness. The built-in 2.8 mm lens has 105° viewing angle. The IP67-rated housing of the camera protects the electronics against adverse weather conditions. The camera can be powered conventionally from a 12 VDC source or with the use of PoE option (802.3af).
The user can select H.265, H.265, or MJPEG video compression. In the case of the H.265+ compression, the data stream is additionally minimized for static scenes, without noticeable loss of image quality. The compression algorithm, based onH.265, has been optimized by Hikvision for applications in CCTV systems. Compared withH.265, it can reduce by half the data stream, which translates into proportional savings of the disk space or extended data retention time. The camera can operate with NVRs supporting H.265 video compression (series E, K, I).
The camera belongs to a new EasyIP Lite series characterized by high performance and affordable price. The series supports motion detection and video tampering detection. The cameras from the series also provide corridor mode and possibility of defining one Region of Interest (ROI).
The users of Hikvision IP cameras and NVRs can use free Hik-Connect service, which provides remote access to the devices in the case of dynamic IP addresses, or allows for the use of domain names in web browsers. It is necessary to create account and add the devices. The service can be operated via a web browser or applications (for a PC and smartphone).
