Video imagery is stored using the efficient H.264 compression. The maximum refresh rate per channel is 25 frames per second. The resolution, frame rate, bit rate, picture quality etc. can be set separately for each video channel and configured optimally to the site conditions. This therefore allows the best possible setting for, for instance, surveillance over a large area with many details (railway station platforms, public areas, etc.) so that details are clearly recognisable with digital zooming into the picture as required. On the other hand, a lower picture quality, resolution, etc. can be set to reduce network load and memory requirements when surveillance merely has to detect movement in the monitored area. This is also supported by dual video streams: this function allows simultaneous transmission of video imagery from one channel over two video streams that can also be configured -to match the end device for instance (monitor or smartphone). The memory requirement can be reduced even further by individually configuring recording for each channel: it can be set manually, according to a time schedule, or for an alarm or movement.
The FNR-4016/500 has 16 channels, the FNR-4004/500 four. Though the number of possible channels reduces according to the resolution of the connected cameras: the FNR-4016 has 16 available channels for the standard resolution, eight channels for 1.3-megapixel cameras and four channels when 2-megapixel cameras are used. The FNR-4004 can process video data from four standard IP cameras or from two IP cameras with a resolution of 720p. Up to eight SATA hard disks can be installed in the FNR-4016 housing to achieve very large storage capacities. The FNR-4016 has 16 alarm inputs and eight alarm outputs, the FNR-4004 has four alarm inputs and one alarm output.
Further functions include the digital zoom to allow zooming in on relevant details at the click of a mouse for live pictures or during playback, two USB ports for user-friendly data export, integrated
motion detector for each channel, extensive options for user management, PTZ control of connected pan/tilt systems (RS-485), pre- and post-alarm recording and privacy masking, that masks out image areas not to be covered by surveillance, such as windows in a residential building. Automatic camera configuration on the FNR-4004 also simplifies start-up: the IP Recorder automatically searches for connected F Series cameras and fully configures itself so the cameras are then ready for operation in just a few moments.
Software Finitra
The Finitra software solution is included in delivery. Up to 16 video channels can be managed, recorded and operated with Finitra regardless of whether an F Series IP camera, IP dome or IP recorder is connected. Recordings up to a resolution of 2 megapixels per channel are supported. Display on the monitor is real time, different split screen settings can be selected for viewing. Intelligent search functions in the recordings, motion for instance, flexible recording settings options (time schedule, permanent, alarm or motion triggered) and numerous other functions are what make Finitra a comprehensive solution for IP-based video surveillance.
