The included accessories

Hikvision DS-2CD2685FWD-IZS camera is dedicated for professional IP CCTV systems. The compact (bullet) camera has been equipped with 8 MP 1/2.5" CMOS sensor providing good video coverage even in low-light conditions. Along with IR illuminator with range up to 50 m, the camera can also operate in complete darkness. The built-in 2.8-12 mm Motozoom lens allows for remote adjustment of the viewing angle within 115° to 35° range. The image is automatically focused after changing the focal length. Hardware WDR with 120 dB dynamic range guarantees very good visibility of details both in light and dark regions of the scene. The IP67-rated housing of the camera protects the electronics against adverse weather conditions. The camera can be powered conventionally with a 12 VDC source or with the use of PoE option (802.3at).

H.265/H.265+ - higher compression ratios with preserving video quality provided by H.264

The camera implements several video compression methods, H.265+, H.265, H.264+, H.264, MJPEG. Compared with H.264, H.265 can reduce by half the data stream, which translates into proportional savings of the disk space or into extended data retention time. H.265+ and H.264+ are Hikvision standards based on the original systems and optimized for CCTV applications. They further minimize the streams in typical video surveillance scenarios. With the advanced video compression algorithms, the camera can be used in IP CCTV systems based on modern NVRs implementing H.265 standard (the DS-76/77/96NI-I/K series supports H.265+, H.265, H.264+, H.264). Of course, the camera can also operate with older models supporting H.264 (the DS-76/77NI-E series supports H.264+, H.264).

The built-in powerful IR illuminator has a range of up to 50 m. The illuminator based on the newest Exir 2.0 light-emitting technology has ca. 30% higher efficiency compared with traditional IR LED arrays. Additionally, the IR light in the form of a rectangle fits the camera's field of view. This further improves the efficiency of the lighting and eliminates the excessive light intensity in the central part of the scene, typical for majority of IR illuminators. Exir 2.0 illuminators ensure much better luminance uniformity, including corners of the scene, at the same time reducing light pollution in the surrounding environment. Compared with the previous version, Exir 2.0 illuminators feature longer service life thanks to optimized heat dissipation, up to 20,000 hours.

With the support of ANR (Automatic Network Replenishment), any IP camera equipped with a memory card can record video in the absence of network connection. After the restoration of the network connection, the recordings are automatically synchronized with those recorded on the NVR. This ensures continuous coverage of events, even in the case of communication problems between the camera and NVR.

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 K17727 camera has IK10 degree of protection provided by the enclosure against external mechanical impacts.

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.
