AI features in Dahua cameras

---

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

Perimeter protection

---

The main task of the perimeter protection function is to detect the intruder in the event of exceeding a specific line or entering the 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 man from an animal. In addition, the device sends an alarm when the undesirable event is detected.

Smart Motion Detection Plus (SMD+)

---

Thanks to the intelligent algorithm, Dahua Smart Motion Detection technology can determine and categorize the goals that trigger traffic detection and filter side objects. In this way, the amount of false alarms is reduced to a minimum.

Comparison of focal length lenses

---

The camera also has an adjustable 2.7 ~ 13.5mm lens. In addition, it provides remote capacity of the focal control of the lens through the Motozoom function and the autofocus automatic focus function function.

Illuminator IR

---

The camera is equipped with infrared illuminator with a range of work reaching up to 40 meters. LEDs provide a bundle of infrared light that illuminates the monitoring area at night.

Built-in microphone

---

A sensitive microphone is built in the camera, which allows you to keep additional audio signal registration, in parallel with video material.

Memory card slot

---

The camera also has a microSD card socket with a maximum capacity of 256 GB. The card is used as a spare memorial site that can be used to create local copies of recordings.

3DNR - Noise reduction system

---

The noise reduction system allows you to maintain image transparency in a situation of variable signal strength level. In practice, this function protects the recordings against the occurrence of so -called The smoking effect and allows you to maintain detailed and crystal clear video recordings.

WDR - Extended dynamic range

---

The WDR function allows you to get a transparent and detailed image, thanks to the skilful leveling of both too bright and darkened fragments of the recording. Thanks to the WDR system, it is possible to maintain the readability of the entire monitoring in places with a varied lighting level of the observed scene.

BLC - Backlight compensation

---

The function allows you to eliminate the resulting effect when the camera is directed towards a strong light source, i.e. when the first plan becomes dark and not legible. Compensation consists in brightening the first plan, unfortunately also at the expense of the background, which also becomes brighter. Generally, the function improves image quality.

HLC - High light compensation

---

The algorithm detects image points that are strongly lit and then masks them enabling effective observation. HLC mode is extremely useful when observing underground parking lots. It allows you to read the license plates numbers that are covered with "bright stains" from the headlights.

Smart lighting function

---

The intelligent lighting function allows you to change basic image parameters, such as exhibition, contrast or brightness. The signal processor analyzes the image on an ongoing basis and immediately after detecting the x -ray reduces the power of the infrared illuminator. Thus, the image becomes more pronounced and the x -rays disappear.

RoI - Region of Interest

---

The Region of Interest system allows you to increase the quality of the recorded image in fragments of the observed scene indicated by the user. Thanks to the Roi function, economic recording of recordings and saving the total video files with the original image quality in priority areas is real.

Dodatkowe funkcje

Starlight camera

---

Dahua Starlight is a technology designed for use in difficult environmental conditions, even with minimal lighting. In the extreme conditions of low lighting, Starlight technology is able to provide a colorful image in almost total darkness.

Powered by PoE technology

---

Power Over Ethernet is a solution developed with a view to carrying out quick and uncomplicated assembly of network devices and comfortable equipment operation and easy installation modernization. Thanks to PoE support in the 802.3af standard, connecting an IP camera will be real using the popular UTP computer pair. Saving the total number of cables necessary to start the device improves the monitoring system and allows the camera to be located away from traditional network power sources.

Support H.265 compression and Smart codec

---

The latest H.265 compression provides 40-50% savings in the field of bandwidth and memory. H265 coding uses advanced technology to improve the ratio between the size of the stream and the quality of the image. The H.265 compression format is only supported as part of one manufacturer.Smart codek H.265+ provides high image quality without charging the network. H.265+ coding has dynamic GOP, dynamic roi, flexible creation of frames and intelligent noise reduction. It provides saving of the bandwidth and disk space up to 70% compared to the H.265 standard.
