Compact IP Camera: Hikvision DS-2CD2T66G2-2I (C) (6 MP, 2.8mm, 0.005 lx, IR up to 60, WDR H.265, AcuSense)

Support

Details

Hikvision Compact IP camera DS-2CD2T66G2-2I(C) belongs to the second generation of cameras with the AcuSense technology, notable for even more effective filtering out of false alarms. The device is dedicated for use in CCTV systems based on IP DVRs/NVRs. The camera is fitted with an 6 MP 1/2.4" CMOS sensor and an IR illuminator with a range up to 60 m to ensure proper visibility in low-light conditions. It has a fixed 2.8 mm lens with a viewing angle of 105°. Support for the legacy and latest H.265(+) compression methods allows for the archiving time of recordings to be extended while maintaining excellent image quality and backward compatibility. Additional functions to help improve image quality including: AGC, 3D-DNR, WDR (120 dB), BLC, HLC and built-in image analytic functions (VCA) make the camera suitable for use in even more advanced projects. The IP67 rated housing protects the inside electronic components from adverse weather conditions. The camera can be powered conventionally with 12 VDC or through PoE (compliant with the 802.802.3af standard).
NOTE! Current software version is available

EasyIP 4.0 – 2 gen. AcuSense
The camera is a part of the EasyIP 4.0 series, which includes models featuring two key technologies: AcuSense (first and second generation) or ColorVu. AcuSense cameras rely on Deep Learning algorithms to classify targets as human or vehicle and use intelligent VCA features, allowing to detect motion (second generation, traditional algorithm), intrusion, line crossing, entering and leaving. Thanks to precise recognition features, the system is able to filter out up to 90% (and even more for second-generation devices) false alarm triggers (e.g. animals, raindrops, spider webs, swaying leaves), which considerably boosts alarm accuracy and effectiveness while reducing the involved cost. ColorVu cameras, operating in color mode under all conditions, are able to detect all the important details of the scene. Using an AcuSense NVR allows to tap the full potential of the Easy IP 4.0 series. Combining cameras which do not support AcuSense technology (e.g. ColorVu) with AcuSense devices makes it possible to filter out false alarms, classify and search for events in terms of shape (human, vehicle). Below, you can compare the possibilities of combining solutions offered in various series.

Motion Detection 2.0
The motion detection has been enhanced with AcuSense technology, allowing events to be filtered for human and vehicle silhouettes. This improves the performance of the entire system and reduces the number of false alarms that reach the user. Once the filter is turned off, detection can continue as before, detecting all objects.

H.265 (+) compression
Compression is a very important parameter proving the device advancement. The better the compression, the lower the bandwidth requirement with the same subjective quality. H.265 (HEVC - High Efficiency Video Coding) is currently the most efficient compression method. Compared to its predecessor (H.264), it reduces the data stream and the demand for disk capacity by half. Therefore, hard drives with a halved capacity can be used, or recordings can be stored for twice as long. Its improved version H.265+ has been optimized for use in CCTV monitoring systems. They allow for further reduction of data streams.
H.265/H.265+ - higher compression ratios with preserving video quality provided by H.264
iVMS-4200 client software
iVMS-4200 is client software dedicated to the management and supervision of Hikvision security systems, such as DVRs (IP, TurboHD), video intercoms, access control, set-top boxes, etc. The software allows you to easily and conveniently monitor all systems by offering viewing from IP cameras, remote playback of recordings, remote configuration, handling of alarm events, two-way audio transmission, e-map support, recording to a HDD and many more.

Access via P2P cloud - Hik-Connect application
Hikvision devices can be operated via mobile phones with Android or iOS using the dedicated Hik-Connect mobile application. It can be used for remote live viewing from DVRs, NVRs, IP cameras, video intercoms over the WiFi, 2G or 3G and to view saved recordings. Operating video intercoms with the application provides also remote opening of the electric strike, receiving notifications and transferring calls from the entrance panel to the phone in the absence of the subscriber. The application supports connectivity over IP and a P2P cloud. Hik-Connect is also the name of the cloud service that provides access to devices in the absence of an external IP address.
Continuity of recordings guaranteed thanks to the ANR function

The main window of the SADP software
SADP (Search Active Device Protocol) is a free, easy-to-use utility designed to search for Hikvision IP cameras and DVRs/NVRs in the local network. The network device search tool can also be used to modify device network parameters, e.g. to change or recover default passwords. Detailed information on the software, its use and password recovery (par. 8) can be found in the following article: SADP application - LAN tool for organizing CCTV systems based on Hikvision devices.
