The DS-2CD1321-I camera is designed for IP CCTV systems. The ceiling camera is equipped with a 2 MP 1/2.8" CMOS sensor, which provides good video even in low light conditions. With a 30 m range IR light source, the camera can work even in total darkness. The 2.8 mm lens It has a 95° viewing angle.The camera is IP67 protected and protects the electronics from adverse weather conditions.The camera can be powered by a conventional 12VDC power supply or by using the PoE option (802.3af).

The user can choose H264+, H.264 or MJPEG video compression. With H.264+ compression, the data stream is minimized for static scenes without any noticeable loss of image quality. The compression algorithm based on H.264 was optimized by Hikvision for CCTV system applications. Compared to H.264, the data stream can be halved, which is also responsible for the proportional saving of disk space or the extended data retention time. The camera can work with NVRs (E, K, I series) that support H.264/H.264+ video compression.

The camera belongs to a new EasyIP Lite series, characterized by high performance and an affordable price. The series supports motion detection and video tamper detection. The series cameras can also use corridor mode and offer the possibility to define a region of interest (ROI).

Camera users can use the free Hik-Connect service, which provides remote access to the device and NVR with a dynamic IP address, or allows you to use the domain name in a web browser. It is necessary to create a Hik-Connect account and add it to the camera. The service can be operated via a browser or through the applications (for PC and smartphone).

Ezviz (EasyVision) is a free service to activate Hikvision NVR and IP cameras. This free service allows even less experienced users to easily access video from cameras over the Internet without forwarding it to a router port. Remote access is possible for the user if the device is connected to the network (which includes a valid IP address and appropriate gateway settings). The next step is to create a user account on the www.ezviz7.com website. The account accepts devices on a local network (by activating the Ezviz service). The devices will then be accessible from anywhere via the Internet.

SADP (Search Active Device Protocol) is a free and easy-to-use utility to search for Hikvision IP cameras and Hikvision DVR/NVRs in your local network. The network device finder can also be used to modify the network parameters of Hikvision devices, including changing passwords or restoring default passwords.
