HD-SDI Cable Connection & Sourcing Warning *** Important Notice Regarding Warranty
Do not connect any camera cable to the FHD4G, FHD4W or FHD4C High Definition DVR while the DVR is powered up, or while any of the LED
indicator lights are illuminated, or this action will VOID the Warranty of the FHD4G, FHD4W or FHD4C DVR.
HD-SDI signal speed is 1 -1.5 GHz/s and compared to analog signal of 550TVL 270 MHz/s it is 4 -5 times faster so the need for a coaxial cable is
important. HD-SDI dedicated coaxial cables do not exist commercially yet, so the existing coaxial cable with impedance of 75ohm coaxial cable must
be used for installation and when there is a break or BNC connector then the additional elements of external shock must be cautioned while
reconnecting the camera cables or camera extension cables.
Required Camera Cable Connection To DVR Procedure:
•Remove all power from the DVR,
•Check the LED indicator lights to make sure they are not illuminated,
•Connect Camera Extension cable to the camera optical head,
•Then & only then connect camera Extension cable to DVR.
Those who fail to read this warning, and or fail to follow “Required Camera Cable Connection To DVR Procedure” will be liable for all cost
of repairs to the DVR as well as all non-warranty related shipping costs.
