Dahua DH-IPC-HDW2231R-ZS: Starlight technology

System overview The IR Megapixel Vari-focal camera delivers 2MP resolution with a 2.7~13.5mm varifocal lens. The camera's elegant blend of aesthetics combined with a range of easy mounting solutions provides an excellent choice for a variety of small to mid-size applications at an affordable price. Functions Smart Codec (H.265+ & H.264+)Smart Codec is the optimised implementation of standard video compression (H.265 & H.264) that uses a scene-adaptive encoding strategy, dynamic GOP, dynamic ROI, flexible multi-frame reference structure and intelligent noise reduction to deliver high-quality video without straining the network. Smart Codec technology reduces bit rate and storage requirements by up to 70% when compared to the standard video compression. Starlight TechnologyFor challenging low-light applications, Dahua’s Starlight Ultra-Low Light Technology offers best-in-class light sensitivity, capturing colour details in low light down to 0.006lux. The camera uses a set of optical features to balance light throughout the scene, resulting in clear images in dark environments. Intelligent video analysis (IVS)The Dahua camera is equipped with a built-in intelligent analytic algorithm based on video, which can realise intelligent functions like Tripwire and Intrusion, to quickly and accurately respond to monitoring events in specific area. It can enhance monitoring efficiency. In addition, the camera supports intelligent tamper detection, which generates a warning message when detecting a dramatic scene change, guaranteeing effective video surveillance. Wide Dynamic Range (WDR) The camera achieves vivid images, even in the most intense contrast lighting conditions, using industry-leading WDR technology. For applications with both bright and low lighting conditions that change quickly, true WDR (120 dB) optimises both the bright and dark areas of a scene at the same time to provide usable video. Smart IR technologyWith IR illumination, detailed images can be captured in low light or total darkness. The camera's Smart IR technology adjusts the intensity of camera's infrared LEDs to compensate the distance of an object. Smart IR technology prevents IR LEDs from whitening out images as they come closer to the camera. The camera's integrated infrared illumination provides high performance in extreme low-light environments up to 50m (164ft). Protection (IP67, wide voltage)The camera allows for ±25% input voltage tolerance, suitable for the most unstable conditions for outdoor applications. Its 2KV lightning rating provides effective protection for both the camera and its structure against lightning. Subjected and certified to rigorous dust and immersion tests (IP67), the camera is the choice for installation in even the most unforgiving environments. EnvironmentalDahua cameras operate in extreme temperature environments, rated for use in temperatures from -30° C to +60° C (-22° F to +140° F) with 95% humidity. InteroperabilityThe camera conforms to the ONVIF (Open Network Video Interface Forum) specifications, ensuring interoperability between network video products regardless of manufacturer.

Dahua Technology HAC-PFW3601-A180 3X2MP multi-sensor panoramic HDCVI IR-bullet camera
Dahua Technology HAC-PFW3601-A180 3X2MP multi-sensor panoramic HDCVI IR-bullet camera

Dahua’s multi-sensor Starlight panoramic HDCVI camera provides added flexibility for wide-area video surveillance. Three 2MP sensors work in tandem to create a comprehensive 180-degree 4K image with enhanced details and simultaneously outputs separate three channels of 2MP HDCVI video. This results in four crystal-clear video feeds from just one camera, drastically reducing installation and maintenance costs. Additionally, the multi-sensor camera also supports electronic cruise and multiple motion detection functionality. Its panoramic view makes the camera an ideal choice for large-size businesses and places such as airports, stadiums, parking lots, and shopping centres. Functions 180° panoramic view Equipped with 3x2MP CMOS sensors the PFW3601 camera can monitor full horizontal views and deliver high quality comprehensive 180-degree coverage with no blind spot. The camera is able to provide coverage of wide, open areas, such as airports, harbours, parks, public squares, shopping centres and more. Users will get overall video coverage with just one HACPFW3601 over coax with less hardware, saving you money. Multichannel video output With four BNC interfaces HAC-PFW3601 can output three channels of 2MP separate real-time video corresponding to three independent imaging systems and one channel of seamless stitching panoramic video at the same time. The three-in-one design combines details with full view to meet the efficient and cost-effective installation requirements. Intelligent mode Utilise Dahua's advance intelligent algorithm the panoramic channel is able to support electronic cruise, a.k.a. E-PTZ, which benefits the detection of moving targets in critical areas. Realise the regional area amplification of the panoramic image, the size and location are adjustable as you want. 4 signals over 1 coaxial cable HDCVI technology supports 4 signals to be transmitted over 1 coaxial cable simultaneously, i.e. video, audio, data and power. Dual-way data transmission allows the HDCVI camera to interact with the HCVR, such as sending control signals or triggering alarms. Moreover, HDCVI technology supports PoC for construction flexibility. Long distance transmission HDCVI technology guarantees real-time transmission at long distance without any loss. It supports up to 700m transmission for 4K and 4MP HD video via RG6 coaxial cable, and up to 300m via UTP cable. Simplicity HDCVI technology inherits the born feature of simplicity from traditional analogue surveillance system. Meanwhile, by having one PFW3601 camera, users can get several different monitor points, making it the best choice for investment protection. On the other hand, the HDCVI system can seamlessly upgrade the traditional analogue system without replacing existing coaxial cabling. The plug and play approach enables full HD video surveillance without the hassle of configuring a network. Wide Dynamic Range Embedded with industry leading wide dynamic range (WDR) technology, vivid pictures are achieved even in the most intense contrast lighting conditions. True WDR (120dB) optimises both the bright and dark areas of a scene at the same time to provide usable video. Advanced 3DNR 3DNR is noise reduction technology that detects and eliminates random noises by comparing two sequential frames. Dahua’s advanced 3DNR technology allows remarkable noise reduction with little impact to sharpness, especially under limited lighting conditions. Besides, the advanced 3DNR effectively decreases the bandwidth and saves on storage space. Protection The camera's outstanding reliability is unsurpassed due to its rugged design. The camera is protected against vandalism with IK10-rated and IP67 water-proof, making it suitable for most environments; such as public places, manufacturing and commercial facilities. Supporting ±25% input voltage tolerance, this camera suits even the most unstable power supply conditions. Its 4KV lightning rating provides protection against the camera and its structure from the effects of lightning.
