The most important parameters of the camera

IPC-HFW2231S-S-S2 is a low-budget IPC Lite series camera , used for building vision systems. The device is equipped with a 1/2.8 "2MP Progressive Scan CMOS image sensor , which allows you to capture video recordings in Full HD resolution . The sensitivity in Starlight technology and numerous available correction functions, including WDR, 3DNR, ensure excellent image quality. Fixed focal lens 2.8 camera mm enables accurate recording of the observed scene, and the built-in IR illuminator with a range of 30mensures that 24/7 monitoring is carried out, with the observance of particularity and legibility of the recordings obtained. The advantage of the camera is also the function of intelligent image analysis, which increases the level of security and guarantees the detection of all undesirable behavior. The device is characterized by a high degree of resistance to adverse weather conditions (IP67).

Intelligent image analysis functions - IVS

A very big advantage of the Dahua camera is the support for functions related to intelligent analysis of the recorded image . It includes virtual line crossing systems and intruder detection in the field of view. Appropriate configuration of the presented functions results in constant or temporary analysis of the recorded image and enables very quick capture of undesirable events.

Sharp and clear image

The camera for working in the IP system should be distinguished by the ability to accurately archive video material with maintaining a large amount of details and full animation fluidity. The IPC-HFW1230S-0280B-S4 network camera guarantees uninterrupted capture of surveillance recordings while maintaining a natural color palette and high image fluidity. Due to the fact that IP cameras are often used in changing observation conditions, the presented Dahua device is equipped with a number of technologies ensuring the insensitivity and active adaptation of the camera to the heterogeneous monitoring environment.

Noise Reduction - 3D NO
The noise reduction system allows to maintain the clarity of the image in the situation of changing signal strength levels. In practice, this function protects recordings against the so-called smudging effect and allows you to keep detailed and crystal clear videos.

DWDR function
A software-based technique that makes it easier to identify objects in dark areas of an image by using gamma correction (preserves natural shadows and lighting - as opposed to simply changing brightness or contrast). DWDR is a cheaper and inferior variation of WDR.

RoI function
The Region of Interest system allows to increase the quality of the recorded image in the fragments of the observed scene indicated by the user. Thanks to the ROI function, it is possible to capture the recordings economically and save the total size of the video files while maintaining the original image quality in priority areas.

Smart IR function
The Smart IR function allows you to change basic image parameters such as exposure, contrast and brightness. The signal processor analyzes the image on an ongoing basis and reduces the power of the IR illuminator immediately upon detection of overexposure. Thus, the image becomes clearer and the highlights disappear.

Privacy masks

Effective video monitoring systems also include intelligent systems of selective video recording. Using the properties of the camera with the privacy zone function, it will be possible to individually adjust the way the observation system operates to the spatial specificity and security requirements of a specific installation site. Thanks to the system of privacy masks, it is possible to freely determine the fragments of the image that will be excluded from the video surveillance.

Camera with PoE technology

Power over Ethernet is a solution developed for quick and easy installation of network devices, comfortable operation of the equipment and easy modernization of the installation. Thanks to PoE support in the 802.3af standard, it will be possible to connect an IP camera using the popular UTP twisted-pair cable. The saving of the total number of cables necessary to start the device improves the monitoring system and allows the location of the camera away from traditional mains power sources.

Advanced H.265 compression
The latest H.265 compression delivers 40-50% savings in bandwidth and memory. H265 encoding uses advanced technology to improve the ratio between stream size and image quality. The H.265 compression format is only supported natively within one manufacturer.

Smart H.265 + codec
The H.265 + smart codec ensures high image quality without burdening the network. This codec is optimized for H.265. H.265 + encoding has dynamic GOP, dynamic ROI, flexible framing and intelligent noise reduction. Provides savings in bandwidth and disk space up to 70% compared to the H.265 standard.

Dahua ToolBox
Dahua ToolBox is a distribution platform for all kinds of applications (eg Smart PSS, ConfigTool, etc.), thanks to which you can easily configure the equipment, update it or generally manage the local and remote CCTV system.
The latest version of the Dahua ToolBox platform available directly from the manufacturer's website.

ConfigTool
ConfigTool is an easy-to-use application used to search, configure and update Dahua devices. One of the important functions of the program is the modification of access passwords and their reset. Configtool quickly finds cameras and recorders in the subnet using the MAC address.

Smart PSS software

Comprehensive management and supervision over the security system and the network of surveillance cameras determine the effectiveness of each video monitoring installation. The company Dahua designed for the user of personal computers PC and MAC developed software Smart PSS to the creation and personalization of their own surveillance system. Smart PSS can cooperate with up to 256 devices and, in addition to displaying live images or playing back recordings, it allows for multi-monitor operation, e-maps and e-PTZ support, video analytics and face detection options or advanced search for individual events. Thanks to the versatility of the program, it is possible to manage both CCTV cameras of high-definition analog system and megapixel IP cameras on a daily basis. The latest version of Smart PSS software can be downloaded directly from the manufacturer's website.

DSS Express
DSS Express is an easy-to-use VMS system for installation on a PC / server. The software is used to meet the basic requirements for operation and video surveillance in CCTV systems. DSS Express can be easily extended with a license, providing the operator with providing solutions with access control, VDP systems and alarm devices. DSS Express is the perfect solution for small and medium-sized projects.

DSS Pro
DSS Pro is an efficient, flexible, scalable and highly reliable central management system. Thanks to the client-server architecture that allows for integration with many surveillance systems, DSS Pro ensures central management, information exchange, convenient connections and cooperation of many services. It allows you to manage devices, alarms and user rights. It provides functions of central data storage, support for vision walls, maps and advanced functions.

Mobile applications

DMSS
DMSS is an application designed to view the image from cameras and to manage Dahua recorders on smartphones and tablets. The program allows you to remotely control devices (recorders, IP cameras), view image, remote PTZ control, audio support, taking pictures (snapshots) or recording movies (monitoring recordings), etc..

DSS Mobile2 is a security surveillance software designed in collaboration with the Dahua DSS platform. It has a user-friendly interface and offers a smooth video game experience, supports multi-point touch and gesture recognition, enables real-time preview, playback, PTZ control and e-map management from IP cameras, IP speed dome cameras, DVR and NVR
