Day & Night Network Camera 221 10-Pack
High performance, professional day and night network camera
The AXIS 221 Day & Night Network Camera is a high performance camera for round-the-clock surveillance over IP networks.
With the ability to provide high quality images under all lighting conditions, the AXIS 221 is an ideal solution for indoor and outdoor applications, including the surveillance of buildings, roads, parking areas, garages, railway stations and airports. The camera is supported by the industry's largest base of video management software for video and alarm management.
The AXIS 221 features an automatic, removable infrared-cut filter, which enables the camera to provide color video when there is sufficient light, and black and white video in dark conditions. It uses a high performance Pentax lens and a progressive scan CCD image sensor that enables moving objects to be presented without distortion. In addition to support for 45 frames per second at all resolutions, the AXIS 221 offers simultaneous Motion JPEG and advanced MPEG-4 video streams to optimize image quality and bandwidth efficiency.
Power over Ethernet Technology background The AXIS 221 also supports a number of advanced features that give the camera increased flexibility and capabilities, including Power over Ethernet, video motion detection, pre- and post-alarm buffer, and inputs/outputs for connecting external devices such as door sensors and relays to activate light or close doors. Power over Ethernet makes the installation easier, cheaper and more secure since Power over Ethernet can take advantage of UPS (uninterrupted power supply), which provides back-up power in case of a power failure.
