The Hikvision DS-2CD2146G1-I camera is dedicated for professional IP CCTV systems. The ceiling camera has been equipped with high quality 4 MP 1/2.7" CMOS sensor providing good video coverage even in very 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 104° viewing angle. 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 (802.3af).

The camera belongs to EasyIP 4.0 series and uses AcuSense technology. The technology is based on deep learning algorithms enabling classification of objects and thus filtering false alarms. The objects are classified according to human figures and vehicle shapes. Currently, the use of this functionality is possible for VCA events such as:

The idea of AcuSense technology

Thanks to the proper recognition, the system can filter out even 90% of events that would trigger false alarms caused, for example, by the movement of trees in the wind, rainfall, or changes in lighting. This significantly increases the accuracy and effectiveness of alerting and contributes to lowering the workload of the operator(s) and costs of sending intervention groups.
Additionally, the Dark Fighter (Ultra-low-light) technology ensures exceptional image quality in ultra-low light environments.

H.265 ensures deeper video compression, preserving the image quality of H.264

The camera implements several video compression methods, H.265, 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. With the H.265 video compression algorithm, the camera can be used in IP CCTV systems based on modern NVRs implementing H.265 standard. Of course, the camera can also operate with older models supporting H.264.

The built-in powerful IR illuminator has a range of up to 30 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), each the 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 iVMS 4200 client software enables users of HIKVISION devices to manage them in IP networks. The software allows for configuration and management of NVRs/DVRs, IP and analog cameras (in hybrid systems). The iVMS 4200 utility can remotely manage up to 256 devices, with the use of up to 4 monitors. One monitor can display up images from up to 64 cameras. Aside from system configuration and live monitoring, the utility can be used for remote playback, notifying, two-way audio transmission, creating multi-level e-maps.

Hik-Connect is a mobile application, intended for smartphones running Android or iOS operating systems. It can be used for remote live viewing of images from DVRs, NVRs, network cameras via Wi-Fi, 2G or 3G networks, and for playing back recorded video files. The application connects with the devices by IP addresses and/or through the P2P cloud.

Hik-Connect is also a network service for Hikvison devices. The service is based on data processing in the cloud and integrates the following functions:

• Remote access through the cloud - it allows access to the device without having an external IP address and when simplicity is the most important thing. Only the basic configuration of the network is required. The application on a PC or smartphone connects with the device via P2P cloud service,
• DDNS server - DDNS assigns a fixed domain name to dynamically changing IP addresses (Dynamic DNS). This feature is useful when the ISP does not provide users with a fixed IP address. The condition for using DDNS is having a public IP address and providing access from the external network to the appropriate ports of the NVR (server and http, by default 8000 and 80). The connection is possible via a web browser, client application on a PC and on smartphones.

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 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.
