In the rapidly evolving landscape of video surveillance technology, the Dahua SD8A440PA-HNF-5G camera stands out as a remarkable innovation. This camera is not just a device for monitoring; it's a sophisticated integration of multiple cutting - edge technologies that make it suitable for a wide range of demanding surveillance scenarios.
System Overview: An All - in - One Surveillance Solution
The SD8A440PA-HNF-5G is equipped with an advanced AI chip, enabling it to provide an all - in - one solution for large - area video surveillance. Unlike conventional cameras, it boasts an extended monitoring range and the ability to automatically track targets.
Thanks to its infrared technology, this camera can produce vivid images both day and night, ensuring high - quality surveillance footage regardless of lighting conditions. Its suitability for various scenarios, especially advanced defense areas requiring high - level control, is further enhanced by the option for a custom - made anti - corrosion structure and IK10 rating.
Protection and Environmental Adaptability
The camera offers robust protection features, including an IP67 rating, which means it is dust - tight and can be immersed in water up to 1 m deep for 30 minutes. The TVS 8000 V protection provides lightning proof, surge protection, and voltage transient protection, ensuring the camera can withstand harsh weather conditions and voltage fluctuations.
This makes the camera highly reliable and durable, reducing the risk of downtime and the need for frequent maintenance in outdoor or challenging environments.
Imaging Technology: Capturing Every Detail
High - Quality Image Sensor and Starlight Technology
At the heart of the camera is a 1/1.8" 4Megapixel STARVIS™ CMOS image sensor. This sensor, combined with Starlight technology, allows the camera to capture high - quality images even in extremely low - light conditions. The minimum illumination is as low as 0.005 lux@F1.4 in color mode and 0.0005 lux@F1.4 in black and white mode. When the IR light is on, it can operate at 0 lux, ensuring round - the - clock surveillance.
IR Illumination and Distance
The camera is equipped with 10 IR illuminators, providing an impressive IR distance of up to 500 m. This enables the camera to monitor large areas effectively, even in complete darkness. The illuminator on/off control is designed with a zoom priority and manual option, offering flexibility in different monitoring scenarios.
Optical Zoom and DORI Distance
With a 40× optical zoom lens, the camera can capture detailed images of objects from a distance. The lens has a focal length ranging from 5.6 mm to 223 mm and a maximum aperture of F1.4–F4.5. The field of view varies accordingly, allowing for both wide - area monitoring and close - up observation.
The DORI distance (Detect, Observe, Recognize, Identify) of the camera is another notable feature. According to the standard system EN - 62676 - 4, the camera can detect objects up to 3,034.5 m away, observe up to 1,198.6 m, recognize up to 606.9 m, and identify up to 303.4 m. This makes it highly effective for long - range surveillance applications.
Intelligent Features: Enhancing Surveillance Efficiency
IVS Technology
The camera incorporates Dahua's advanced IVS (Intelligent Video Analysis) technology, which uses sophisticated video algorithms to support various intelligent functions. These include tripwire detection, intrusion detection, climbing fence detection, loitering detection, abandoned/missing object detection, fast - moving object detection, parking detection, people gathering detection, and vehicle/human alarm classification. When an event is detected, the camera can trigger linkage tracking, enabling real - time response to potential security threats.
Face Recognition
Face recognition is a key intelligent feature of this camera. It can extract face attributes from captured faces and store them in an internal database that can hold up to 10,000 face images. This allows for real - time capture and comparison of face images. The camera supports face detection, optimization, tracking, capturing pictures, uploading high - quality face snapshots, and face enhancement. It can extract 6 face attributes (gender, age, glasses, mask, mustache) and recognize 8 facial expressions (angry, sad, hate, scary, surprise, calm, happy, confused).
Video Metadata
The camera supports video metadata extraction, which includes information on human faces, human bodies, motor vehicles, and non - motor vehicles. This metadata can be used for efficient data retrieval and analysis. Face information includes gender, age, glasses, masks, beards, etc. Human body information covers hat, top, top color, bottom, bottom color, bag, etc. Motor vehicle information includes license plate color, type, vehicle color, sun visor, seatbelt, smoking, calling, ornament, annual inspection sticker, etc. Non - motor vehicle information includes type, color, top type, top color, number of people, etc.
Network and Communication: Staying Connected
Equipped with a built - in high - performance 5G mobile communication module, the camera supports 5G network connection and two networking methods: Non - Standalone (NSA) and Standalone (SA). It is backward compatible with 4G connections. This wireless connectivity allows the camera to register on the platform and transmit videos, pictures, intelligent feature information, and alarm events. Users can remotely monitor and operate the camera in real - time through a client.
The camera also supports various network protocols, including TCP, FTP, RTMP, IPv6, IPv4, DNS, RTCP, PPPoE, NTP, RTP, 802.1x, HTTPS, SNMP, DDNS, UPnP, ICMP, UDP, IGMP, HTTP, DHCP, SMTP, SNMPv1/v2c/v3(MIB - 2), Qos, RTSP, ARP, ensuring smooth network communication and interoperability.
Video Compression and Streaming: Optimizing Performance
The camera adopts Smart H.265+ technology, which is an optimized implementation of the H.265 codec. It uses scene - adaptive encoding strategies, dynamic GOP, dynamic ROI, flexible multi - frame reference structures, and intelligent noise reduction to deliver high - quality videos without straining the network. Compared to standard H.265 video compression, Smart H.265+ reduces bit rate and storage requirements by up to 70%, making it highly efficient in terms of bandwidth and storage usage.
It supports multiple video compression formats, including H.264H, H.264B, Smart H.265+, H.264, MJPEG (Sub Stream), Smart H.264+, H.264M. The streaming capability includes three streams, allowing for flexible viewing and recording options. The video frame rate can be adjusted according to different resolution settings, ensuring smooth video playback.
PTZ (Pan/Tilt/Zoom) Capabilities: Precision and Flexibility
The PTZ function of the camera offers a wide range of movement. The pan range is 0° to 360° endless, and the tilt range is –30° to +90°, with auto flip 180°. The manual control speed for pan is 0.1°/s–240°/s, and for tilt, it's 0.1°/s–75°/s. The preset speed for pan is 220°/s and for tilt is 100°/s. It can store up to 300 presets, 8 tours (with up to 32 presets per tour), 5 patterns, and 5 scans.
The Power - off Memory feature ensures that the camera returns to its previous state after a power failure. The idle motion can be set to pattern, preset, scan, or tour. The PTZ protocol is compatible with DH - SD Pelco - P/D (Auto recognition), making it easy to integrate with other systems.
Audio and Alarm Features: Comprehensive Monitoring
The camera supports audio input and output, with audio compression formats including G.711a, G.711Mu, G7221, G726, MP2L2, G729. This allows for two - way audio communication, enhancing the monitoring experience.
