The user-friendly IP recorders in the F Series - the FNR-4004/500 and FNR-4016/500 - make it truly easy to record over a network.
Video imagery is stored using the efficient H.264 compression. The maximum recording speed 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 FNR-4016/500 has 16 channels, the FNR-4004/500 four. 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.
So much for the common features - but what, in addition to the different channel number, are the differences? The most important difference lies in support to different manufacturers: whilst the FNR-4004/500 is ideal purely for eneo products (F Series, N and G Series currently under development), the FNR-4016/500 also supports products from Axis, Bosch, Panasonic, Sanyo and Sony, so that extra flexibility is provided for product selection during system planning and installation as well as upgrades.
