This camera can come with an optional wiper, this can clear the viewing aperture of the lens in rain, maintaining image quality.
Hikvision's 2MP DarkFighter PTZ camera, DS-2DF8236I-AELW, is capable of delivering up to 2 megapixel resolution images at 25 frames per second (fps). Housed in an IP66 rated casing and featuring a full pan/tilt/zoom function, the DS-2DF8236I-AELW is an ideal external surveillance solution for wide outdoor areas.
The HikvisionDS-2DF8236I-AEL(W) PTZ CCTV camera is an ideal choice for external applications requiring a single camera to capture 24 hour coverage of a large area instead of implementing a number of IP cameras. Typical examples where this unit could be used include warehouse entrances and depots, popular tourism spots and supermarket car parks.
Obtaining closer views of specific areas that are of interest within the scene can be achieved with the 36x optical zoom and the 16x digital zoom allows further investigation into the image. These zooming capabilities result in an ideal surveillance choice in scenarios where the images captured may be needed for use as evidence. Endless 360° pan and 90° tilt allows a wide area to be covered with a single camera, a cost-effective CCTV solution within installations that would normally require multiple units.
An IR cut filter switches between full colour to monochrome night vision automatically when it senses a certain light intensity giving the DS-2DF8236I-AEL(W) True day/night capability, providing round the clock surveillance. The DarkFighter low-light capability technology within this PTZ camera allow for full colour images to be seen even in low light levels as well as an IR range of up to 200m, an ideal surveillance choice in large areas.
Hikvision's Smart tracking detects movement within the scene following the objects movements until it leaves the field of view - thus enhancing the effectiveness of the CCTV surveillance, ideal for an installation that requires a high level of security. Alarms can be set to alert users with a variety of video motion detection within the scene such as; intrusion and line crossing detection, these help to enhance security monitoring and when triggered, notifications can be sent to users via email or mobile devices. Twenty four programmable privacy masks are configurable within this IP camera that prevent operators from viewing certain areas of the field of view that may be private or sensitive.
The network camera also includes a range of image enhancement technologies such as electronic image stabilisation (EIS), which reduces the effects of camera movement from vibrations and defog technology, which filters dust, fog and smoke from images to improve visibility. For scenes in challenging lighting such as dark shadows and bright highlights, wide dynamic range (WDR) ensures detail is captured in all areas and 3D noise reduction improves video quality in low lighting. In addition to these imaging features, backlight compensation is also available to help prevent areas of interest being silhouetted against bright backgrounds. (The DS-2DF8236I-AELW camera even comes with a wiper to deal with water droplets on the lens opening to ensure clear images even in torrential rain.)
H.264, MPEG-4 and MJPEG compression standards are all supported providing flexibility depending on requirements. Triple streaming is supported in this model, reducing bandwidth requirements by enabling up to three streams with different resolutions and frame rates to be configured. A built-in MicroSD card slot (card not included) allows up to 128GB to be stored internally on the camera, providing a back-up in the situation of a network failure.
