The DCS-6915 Outdoor 20X Full HD WDR Speed Dome Network Camera is a high-definition professional surveillance & security solution suitable for small, medium, & large enterprises. The DCS-6915 features a 3 megapixel sensor capable of Full HD 1080p resolution, allowing for very clear surveillance footage to be taken. The powerful 20X optical zoom & 10X digital zoom ensure that you can see even the smallest details with ease. Proportional pan & tilt make it easy to precisely adjust the cameras view. When the camera zooms in, the panning speed is automatically slowed to improve camera tracking & control. PTZ presets allow the camera to monitor specified areas along predefined paths. The broad tilt range from -10° to 190° allows the camera to see beyond the true horizon, meaning you can see more even when zoomed in. Specially designed for use in challenging environments the DCS-6915 has a toughened metal, industry-certified IK-10 (vandal-proof) & IP66 (weather-proof) housing. This means that it is able to withstand sudden high impacts, as well as adverse weather conditions. With its built-in heater & fan, the camera can operate in extreme environments at temperatures ranging from -40 to 50 °C (-49 to 122 °F). To maximize bandwidth efficiency & improve image quality, the DCS-6915 provides real-time video compression using the H.264 & MJPEG codecs. This versatility enables a wide variety of security applications, such as monitoring public areas to detect incidents & to coordinate responses, enforcing access control to restricted areas, deterring criminal activity, or monitoring inventory. Furthermore, bandwidth requirements can be adjusted in real-time over the network, & recorded video files can be saved to an internal Micro SD card 1. IP surveillance cameras are often installed in areas with consistent lighting, like offices, banks or stores. This makes it easy to set exposure levels for optimal image quality.
