IPC-HFW2441T-ZAS-27135 is a variable focal length IPC camera from the WizSense series , used to build vision systems. The device enables recording images from places and objects under 24/7 monitoring, ensuring reliable identification and a high level of security for both people and protected property.

The device is equipped with a 1/2.9" 4MP image sensor, low illuminance, HD CMOS image sensor , which allows for generating images in 2688x1520 resolution . The sensitivity in Starlight technology and available correction functions, including WDR, 3D NR ensure excellent quality of the received image. A motozoom lens , which, using a built-in electric motor, allows for external, remote adjustment of the focal length level, and also automatically adjusts the sharpness level itself. An infrared illuminator with a range of 60m guarantees 24-hour monitoring while maintaining the specificity and readability of the obtained recordings. Additionally, the AI ??artificial intelligence technology with the perimeter protection function and SMD plus , increases the level of security and guarantees the detection of all undesirable behavior. The advantage of the device is also a built-in microSD card slot (256 GB) and a built-in microphone. The IPC-HFW2441T-ZAS-27135 megapixel camera is characterized by a high degree of resistance to adverse weather conditions ( IP67 ).

AI Features in Dahua Cameras

Over the past few years, artificial intelligence (AI) has been applied in various ways in the security market. With the development of technology, AI performance has improved, which has contributed to the greater accuracy of the offered solutions. Unlike standard intelligent functions (IVS), AI solutions can improve the precision of image content analysis. Dahua WizSense network cameras have new intelligent functions that work even in the most difficult lighting conditions, and thanks to deep learning algorithms, the device performs key tasks better than before, such as perimeter protection, image structuring with division into categories of recognized objects.

Perimeter protection

The main task of the perimeter protection function is to detect an intruder when they cross a specific line or enter a protected area. The Deep Learning camera is able to distinguish objects that violate the controlled area, e.g. a tree from a car, or a person from an animal. Additionally, the device sends an alarm when an unwanted event is detected.

Smart Motion Detection Plus (SMD+)

With the intelligent algorithm, Dahua Smart Motion Detection technology can identify and categorize targets that trigger motion detection and filter unwanted objects. In this way, false alarms are reduced to a minimum.

Noise reduction system - 3D NR

The noise reduction system allows you to maintain image clarity in the event of a fluctuating signal strength level. In practice, this function protects recordings from the so-called ghosting effect and allows you to maintain detailed and crystal clear video recordings.

Region of Interest - RoI function

The Region of Interest system enables the quality of the recorded image to be increased in parts of the observed scene indicated by the user. Thanks to the ROI function, it is possible to economically record recordings and save the total size of video files while maintaining the original image quality in priority areas.

Extended Dynamic Range - WDR

The WDR function allows you to obtain a clear and detailed image, thanks to the skillful leveling of both too bright and dark fragments of the recording. Thanks to the WDR system, it is possible to maintain the readability of the entire monitoring in places with different levels of lighting of the observed scene.

Back Light Compensation - BLC

The function allows you to eliminate the effect that occurs when the camera is pointed towards a strong light source, i.e. when the foreground becomes dark and illegible. Compensation consists of brightening the foreground, unfortunately also at the expense of the background, which also becomes brighter. In general, the function improves the image quality. 

High Light Compensation - HLC

The algorithm detects image points that are strongly illuminated and then masks them, allowing for effective observation. HLC mode is extremely useful when observing underground parking lots. It allows reading license plate numbers that are covered by "bright spots" from the headlights.

Privacy Masks

Using the privacy zone camera features, it is possible to adapt the way the observation system works to the spatial specificity and security requirements of a specific installation location. Thanks to the privacy mask system, it is possible to freely designate parts of the image that will be excluded from video surveillance.

Starlight technology camera

Dahua Starlight is a technology designed for use in difficult environmental conditions, even with minimal lighting. In extreme low-light conditions, Starlight technology is able to provide color images in almost complete darkness.

Power supply via PoE technology

Power over Ethernet is a solution designed for quick and easy installation of network devices, convenient operation of 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 computer twisted pair. Saving the total number of cables necessary to run the device improves the monitoring system and allows the camera to be located away from traditional mains power sources!

 

Smart codec support

Smart H.265+ codec provides high image quality without burdening the network. H.265+ encoding has dynamic GOP, dynamic ROI, flexible framing and intelligent noise reduction. It provides bandwidth and storage savings of up to 70% compared to the H.265 standard.

Software

In order to improve the operation of its products, Dahua Technology also offers free or paid software packages intended for installers, companies and home users.

Dahua ToolBox

Dahua ToolBox is a platform for distributing all kinds of applications (e.g. Smart PSS, ConfigTool, etc.) thanks to which you can easily configure the equipment, update it or generally manage the local and remote CCTV system.

ConfigTool

ConfigTool is an easy-to-use PC application used to search, configure and update Dahua devices. One of the important functions of the program is to modify access passwords and reset them. Configtool quickly finds IPC cameras, recorders (NVR, XVR), access control devices and VDP video intercoms in a subnet using the MAC address.

Smart PSS Software

Dahua has created Smart PSS software for PC and MAC users to create and personalize their own observation system. Smart PSS can work with up to 256 devices and, in addition to displaying live images or playing back recordings, it allows for multi-monitor operation, e-map and e-PTZ support, video analytics support, face detection options, and advanced search for individual events.

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 video operation and surveillance in CCTV systems. DSS Express can be easily extended with a license, providing the operator with access control solutions, VDP systems and alarm devices. DSS Express is the ideal 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 allowing integration with many surveillance systems, DSS Pro provides central management, information exchange, convenient connections and cooperation of many services. It allows management of devices, alarms and user permissions. It provides data storage functions, video wall support, maps and advanced functions.

DMSS

DMSS is an application designed to view images from cameras and to manage Dahua recorders on smartphones and tablets. The program allows for remote device operation (recorders, cameras), image preview, remote PTZ control, audio support, taking pictures (snapshot - image dumps) or recording - monitoring recordings, etc.
