Dahua launches 800TVL camera - unveiling the evolving and better

Dahua Technology releases the leading industry 800TVL analogue cameras — 19-series, which unveils the evolving and better “Analogue+ Era”. The image quality has been brought to a new height throughout analogue history. The 800TVL 19-series cameras feature in-house Mega-HDIS technology (Mega-High Definition Image Sensor), delivering ultra-high image resolution (1280x960). The advanced image sensor can achieve twice better resolution than the previous one, which is equally to 1.3-Megapixel in IP resolution. This series also uses an advanced ISP chipset, allowing the outputting frame rate up to 50fps that makes real-time preview and playback superb smooth. Image quality In addition to the outstanding outdoor/indoor performance under enough light sources, the 19-series is capable of rendering excellent image even at night or under low-light condition. 3D-NR The 3D-NR technology provides a more accurate noise reduction. Smart IR Smart IR solution features non-LDR (light-dependent resistor) technology, enabling an intellectual algorithm to detect more accurate timing of switching on/off ICR filer as well as to adjust the IR LEDs current for better visual effect under low-light scenarios. The first wave of 800TVL 19-series camera release includes six models, (FW191G/FW191D/FW191J/ D190C/DW191H/DW191E) with various designs and sizes; lenses are selectable from 2.8mm to 16mm, which satisfies diverse applications either indoor or outdoor. With all mentioned above, this camera series presents the highest image resolution in analogue history ever, which is apparently ideal for applications where high image quality is valued.

System overviewExperience 4MP video and the simplicity of using existing cabling infrastructure with HDCVI. The Cooper series 4MP HDCVI camera features a compact design and offers a high quality image at a friendly price. It offers various vari-focal/fixed lens models with a multi-language OSD and HD/SD switchable output. Its structural flexibility and high cost-performance makes the camera an ideal choice for SMB solutions. Functions 4 signals over 1 coaxial cableHDCVI 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 signal or triggering alarm. Moreover, HDCVI technology supports PoC for construction flexibility.* Audio input is available for some models of HDCVI cameras. Long distance transmissionHDCVI technology guarantees real-time transmission at long distance without any loss. It supports up to 700m for 4MP HD video transmission via coaxial cable, and up to 300m via UTP cable. **Actual results verified by real-scene testing in Dahua's test laboratory. SimplicityHDCVI technology inherits the born feature of simplicity from traditional analog surveillance system, making itself a best choice for investment protection. HDCVI system can seamlessly upgrade the traditional analog system without replacing existing coaxial cabling. The plug and play approach enables full HD video surveillance without the hassle of con-figuring a network. Smart IRThe camera is designed with array LED IR illumination for best lowlight performance. Smart IR is a technology to ensure brightness uniformity in B/W image under low illumination. Dahua’s unique Smart IR adjusts to the intensity of camera's infrared LEDs to compensate for the distance of an object, and prevents IR LEDs from overexposing images as the object come closer to the camera. Multi-formatsThe camera supports multiple video formats including HDCVI, CVBS and other two common HD analog formats in the market. The four formats can be switched over through OSD menu or by PFM820(UTC controller). This feature makes the camera to be compatible with not only XVRs but also most end users’ existing HD/SD DVRs. Multi-language OSDOSD menu provides multiple image adjustments and function settings to meet the requirements of different monitoring scenes. The OSD menu includes configurations such as backlight mode, day/night, white balance, privacy mask and motion detect. The camera supports 11 languages for OSD menu, namely, Chinese, English, French, German, Spanish, Portuguese, Italian, Japanese, Korean, Russian and Polish. ProtectionThe camera's outstanding reliability is unsurpassed due to its rugged design. The camera is protected against water and dust with IP67 ranking, making it suitable for indoor or outdoor environments.With working temperature range of -30 °C to +60 °C (-22 °F to +140 °F), the camera is designed for extreme temperature environments. Supporting ±30% 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.

System Overview The IR Megapixel Fixed camera delivers 2MP resolution with a motorized 2.8mm/3.6mm fixed 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. Intelligent Video Analysis (IVS)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 is to generate warning message via detecting dramatic scene change and to guarantee effective video surveillance. 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 30m (98ft). Protection (IP67, wide voltage)The camera allows for ±25% input voltage tolerance, suitable for the most unstable conditions for outdoor applications. Its 6KV 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. Image FlipCapturing unnecessary data such as surrounding hallway walls can increase storage requirements without any added value. The image flip feature allows the camera's image to be rotated in 90° increments for better video optimisation. InteroperabilityThe camera conforms to the ONVIF (Open Network Video Interface Forum) specifications, ensuring interoperability between network video products regardless of manufacturer.
