The SDHD94Q "Quad Box" can convert the analogue signal from up to 4 cameras into one HD video output and can be displayed as a live quad screen image on a single HD recorder input, effectively giving the HD recorder 4 times the input capacity.
The recorded video images from the analogue cameras will be recorded in their true TVL resolution when recorded on a KRATOS HD recorder, surpassing the 540TVL recording limitation that current analogue based DVRs suffer from.
By re-using the analogue cameras in existing instalations, the initial upgrade cost of introducing a KRATOS Full HD recorder becomes very affordable.
