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 H264+, H.264, or MJPEG video compression. In the case of the H.264+ compression, the data stream is additionally minimized for static scenes, without noticeable loss of image quality. The compression algorithm, based on H.264, has been optimized by Hikvision for applications in CCTV systems. Compared with H.264, 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.264/H.264+ 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 Hik-Connect account and add the devices. The service can be operated via a web browser or applications (for a PC and smartphone).

Ezviz (EasyVision) is a free service which can be activated in Hikvision NVRs and IP cameras. This free service allows less advanced users to easily access to the video from the cameras via the Internet, without forwarding router ports. To enable remote access, the user should only connect the device to the network (which requires a valid IP address and appropriate gateway settings). The next step is the creation of user account at the www.ezviz7.com website. The account can accommodate devices in a local area network (with activated Ezviz service). The devices will be available from anywhere via the Internet.

The degree of protection (IK rating) provided by enclosures for electrical equipment against external mechanical impacts is defined in the EN 62262 standard. The EN 62262:2003 standard specifies the conditions of the testing procedure.

The K17282 camera has IK10 rating.

SADP (Search Active Device Protocol) is a free and simple to use utility for searching Hikvision IP cameras and Hikvision DVRs/NVRs in the local network. The network device search tool can also be used for modification of network parameters of the Hikvision devices, including the change of passwords or recovery of default passwords. Detailed information on the software and its use is contained in the SADP application - LAN tool for organizing CCTV systems based on Hikvision devices article.
