Vivotek Hikvision 2MP H.265 Speed Dome Network Camera

Delivering up to 50% saving storage space and network bandwidth, the next generation H.265 video compression standard now is gradually being adopted by major security manufacturers. In IFSEC 2016 security show taking place at the ExCel London exhibition center, companies like Dahua, Hikvision, IDIS, Vivotek and more showcase many H.265 high definition network cameras can operate using a combination of H.264 and H.265 simultaneously. In this article, we intend to introduce you the H.265 2-megapixel IP PTZ cameras from two different companies – Vivotek and Hikvision.

Hikvision Darkfighter DS-2DF8223IW

DS-2DF8223IW is the cutting-edge smart PTZ network camera from Hikvision H.265 DarkFighter series. This camera is designed especially for ultra low light surveillance in large coverage areas, it utilizes Hikvision's industry leading 1/1.9"  2-megapixel CMOS image sensor, and its designed specifically to capture 1080p Full HD video with sharp color and monochrome images in extreme low light environment. 

DS-2DF8223IW is equipped with a powerful auto-iris 23x optical zoom lens (5.9-135.7mm), supports 16x digital zoom. Having high efficient IR illuminators can provide up to 200 meter IR distance, utilizing Smart IR technology can automatically adjust IR-intensity depending on the zoom ratio.

The Darkfighter DS-2DF8223IW PTZ camera also features a wide range of smart functions, including face detection, intrusion detection, line crossing detection and audio exception, benefitting users with great improvement on security efficiency, more importantly, with key events / objects being recorded for further forensic needs. These features, combined with smart tracking, which enables the camera to detect any progressively moving object and follow it within the camera’s area of coverage without fault. Smart Defog and EIS (Electronic Image Stabilization) are further supported to improve image quality in challenging conditions.

Vivotek SD9364-EHL PTZ Camera

Vivotek SD9364-EHL is a professional outdoor speed dome IP camera that supports advanced motion detection and automatic tracking. This camera features a 30x optical zoom lens (f = 4.3 ~ 129 mm) with fast auto-focus,high-speed pan and tilt operations at 300° per second, 255 presets, 110dB Wide Dynamic Range (WDR), and both HEVC/H.265, AVC/H.264, MJPEG video codec. It's an outdoor-ready 1080p Full HD pan/tilt/zoom camera that utilizes industry-leading 1/3" 2-megapixel progressive scan CMOS image sensor can capture 1080p video at maximum 60fps frame rate. 

Powered by Multimedia SoC, it supports defog, electronic image stabilization (EIS), video motion detection, auto-tracking on moving object, alarm trigger and event. Including high efficient 3rd generation infrared illuminators, the camera can see up to 150 meters in complete darkness. By employing Vivotek Smart vari-focal Smart IR technology, provides vari-angle IR coverage to avoid IR-saturation problem. Adopting weatherproof and vandal-proof design, it is suitable for monitoring wide open areas and harsh environments, it can operate in -50°C ~ 55°C (-58°F ~ 131°F) wide temperature range, can be powered by 95W PoH/PoE DC 48V。

H.265 + Smart Stream Technology

Armed with a 20x/30x optical zoom lens, these H.265 Full HD speed dome cameras are able to capture details at top-notch quality. By combing both H.265 and VIVOTEK’s Smart Stream II technology, which enable the cameras to optimize quality for desired regions and maximize efficiency of bandwidth usage, it is capable of reducing both bandwidth and storage consumption by up to 80% while maintaining the highest standard of image quality.

110dB True-WDR

Utilizing WDR Pro technology enables these H.265 cameras to capture details clearly under high-contrast lighting conditions where both dim and brightly lit areas are present in the field of view.

Defog & EIS

The defog feature enables the speed dome cameras to capture clear images under foggy conditions, exponentially enhancing operational performance. The incorporation of EIS technology enables the speed dome cameras to mitigate the effect of camera vibration due to high wind, ensuring a stable image.
