Detalii
The Hikvision dome IP camera DS-2CD2T86G2-2I(C) is part of 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 a 4 MP 1/3" CMOS sensor and an IR illuminator with a range up to 30 m to ensure proper visibility in low-light conditions. It has a fixed 2.8 mm lens with a viewing angle of 103°. Built-in microphone enables sound recording. 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).

The camera described here is part of the EasyIP 4.0 series, which includes models equipped with two key technologies: AcuSense (I and II gen.) or ColorVu. AcuSense cameras are based on Deep Learning algorithms, enabling the classification of targets due to human and vehicle silhouette using intelligent VCA analysis such as motion detection (2nd gen, traditional algorithm), intrusion detection, line crossing, entry and exit of an area. With accurate recognition, the system can filter out up to 90% (2nd gen. over 90%) false alarm triggering events (e.g., animals, rain, cobwebs, moving leaves, etc.) which significantly increases the accuracy and efficiency of alarming and contributes to lower labor costs. With the ability to display a color image in all conditions, ColorVu cameras allow you to record all the details in the monitored scene. With the AcuSense series DVR , you can fully use the possibilities of the Easy IP 4.0 series. By connecting any camera that does not support AcuSense (e.g. ColorVu) and AcuSense cameras to any number of channels, you can filter out false alarms, classify and quickly search for events by silhouette of a person or vehicle. The following are the options which combine solutions from different series.

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.
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.

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.
Hikvision devices can be operated via mobile phones with Android or iOS using the dedicated Hik-Connect mobile application. It can be used to remotely view live video from DVR, NVR, IP cameras, door entry systems using Wi-Fi, 2G or 3G networks and also to view recorded videos. 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 allows connectivity via IP addresses and via 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.
The degree of protection (IK rating) against external mechanical impacts offered by electrical equipment housing is defined in the EN 62262 standard. The EN 62262:2003 standard also specifies the conditions of the testing procedure.
The camera has an IK10 rating.

Extensive applications for the organization and use of CCTV systems
Our library provides an overview of applications dedicated for installers and users of monitoring systems based on Hikvision devices.
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.
