Details

The Dahua IPC-HFW3849T-ZAS-IL-27135 camera is part of the WizSense series and is equipped with an AI chip that enables real-time image analysis. Thanks to advanced deep learning algorithms, the camera effectively recognises people and vehicles, eliminates false alarms and increases detection accuracy. Features such as SMD 4.0, Intelligent Perimeter Security (IVS), AcuPick, AI SSA and Smart Search enable quick event search and automatic adjustment of image parameters to environmental conditions, making this model an ideal solution for professional surveillance systems.
The device captures images at a resolution of up to 8 megapixels and produces high-resolution colour images, even in very low light or complete darkness. Round-the-clock colour performance is achieved through the use of a modern lens, a high-sensitivity sensor and warm white illumination, which ensures a colour image in the absence of sufficient light sources.
Key features:
  • resolution 8 MP – 3840 × 2160 at 25 fps
  • 2.7–13.5 mm motorised zoom lens
  • full-colour – colour images 24 hours a day
  • white light and infrared illuminator with a range of up to 60 m
  • SMD 4.0 (Smart Motion Detection 4.0)
  • intelligent events: line crossing and zone movement detection (entry and exit) with human/vehicle filtering
  • AcuPick enables quick search for recordings featuring a selected person or vehicle
  • Smart Search enables quick searching of recordings based on defined motion detection areas
  • AI SSA (AI Scene Self-Adaptation) uses deep learning algorithms to automatically optimise image functions
  • RTMP protocol, allowing the audio-video stream to be sent directly to popular streaming platforms such as YouTube, Vimeo or Twitch
  • waterproof (IP67) housing
  • built-in microphone
  • alarm connector 1 IN / 1 OUT
  • 1 IN / 1 OUT audio connector for connecting a microphone / speaker
  • microSD card recording capability
  • 12 V DC or PoE (802.3af) power supply
Key features:
Hybrid illuminator with intelligent switching

With the default settings, the camera automatically switches between IR illuminator and white light modes. In night mode, the camera operates with the IR illuminator, but when an object is detected in the monitored area, the scene is illuminated with white light. This provides better identification capabilities (the image is in colour). Additionally, the active deterrent function may be activated, consisting of visual (flashing blue and red LEDs) and audible (audio alerts) signals.

SMD 4.0 (Smart Motion Detection 4.0)

Traditional motion detection worked by detecting changes in the intensity of light reaching a pixel (or larger groups of pixels) on the sensor. Any such change in light triggers detection, which is why the system picks up movement from objects that are irrelevant from a security perspective. Such motion detection is sensitive to, for example, leaves rustling in the wind, flying insects, birds, shadows or precipitation.
The new SMD motion detection system can analyse motion detection events to distinguish between people and vehicles. This ensures that alarm notifications are filtered and unnecessary alarms are blocked. If the system records to a compatible NVR, the footage can be filtered to detect either people or vehicles. The SDM 4.0 feature in the camera is an enhanced version of motion detection, based on deep learning algorithms. Event filtering efficiency reaches 99%, and the detection range has doubled.
Intelligent perimeter protection

The perimeter protection functions - crossing the virtual line and entering the protected zone - can recognise objects of interest. They work on the basis of a deep learning algorithm and can accurately recognise people and vehicles. As a result, false alarms caused by irrelevant objects can be significantly reduced. Recordings can be quickly filtered to isolate these objects.
Full-color technology
Full-colour cameras capture high-resolution colour images day and night. They are characterised by a very high sensitivity of 0.003 lux, so that the camera requires low light levels to generate a useful image - street lighting or moonlight is sufficient. This is made possible by fitting a lens with a large F1.0 aperture - more light reaches the sensor. In addition, the more sensitive sensor handles incident light more effectively and the signal processor maintains a balance between noise reduction and blurring of moving objects. If there is insufficient light, the built-in white light illuminator is switched on.
The 24-hour colour image ensures better identification of details of vehicles or people. A particularly important advantage in night-time operation is that there are no reflections from precipitation or insects, which are common problems in IR illuminator operation.
RTMP protocol for transmitting video and audio directly to popular streaming platforms
The camera supports the RTMP (Real-time Streaming Protocol), which is required to connect to popular streaming platforms (YouTube, Vimeo, Facebook, Twitch, etc.). This allows you to broadcast live to a virtually unlimited audience. It is ideal for broadcasting events such as Masses, church services, sports matches, training sessions or remote learning.
Starlight
The camera is equipped with a high-sensitivity sensor (0.003 lx), which allows it to produce a usable image even in low light conditions. Reduced noise results in better image quality, and compression is also more efficient. The image in daylight conditions features accurate colour reproduction, and the camera itself switches to night mode later than in standard solutions.
Extended Dynamic Range (WDR) 120 dB

Correct operation of surveillance cameras in difficult lighting conditions is one of the top priorities of equipment manufacturers. The dynamic range of the sensor is a parameter which describes the ability of the camera to simultaneously register very bright and dark areas. Cameras with high dynamic range (WDR) perform better when observing frames with high lighting contrast. The image in most WDR-equipped cameras is created by exposing the sensor with different exposure settings (slow shutter for dark elements and fast shutter for bright elements). The resulting image is a combination of both frames and processing based on the algorithms set by the manufacturer.

H.265 compression (+)
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.

Privacy zones
Obscuring selected areas in the frame is an important element of surveillance systems. For this purpose, the privacy zones function has been introduced in the cameras. It allows certain parts of the camera's field of view to be made invisible (masked). Examples of places that require this are building windows, toilets in school bathrooms, prison bathrooms, etc. If these places were not masked, personnel with access to the monitoring equipment could violate the privacy of the monitored persons and thus break the applicable law.
PoE power supply
PoE (Power over Ethernet) is the name of the IEEE standard for powering network devices via twisted pair cable while transmitting data. It is possible to supply power to devices such as cameras, telephones, switches, access points, etc. The guaranteed transmission distance for power supply is 100 m. The two most popular standards are 802.03af, which guarantees a minimum power of 12.95 W for end devices, and 802.3at – power of 25.5 W.
