Caution: Installations in Lightning Prone Areas
In lightning prone areas, in-line coaxial lightning arresters should be used on the
video cables. The arresters should be installed at the cable entry of the building that
houses the FastTrace-R. Cameras should also have suitable lightning protection
rods installed as close to them as possible. The use of fibre optics to provide
electrical isolation on the video signals is strongly recommended in high-risk areas.
Figure 40: Video Configuration
3.4.1 Video Input Requirements
To ensure high quality images, the FastTrace-R must synchronise correctly to the incoming video
signal for the selected video standard. For synchronisation to occur the following conditions must
be met:
• the synchronisation pulse amplitude at each video input must be within the range of
0.2 volts to 0.4 volts,
• the peak video amplitude with reference to the black level (ie. not including the
synchronisation pulses) at each video input must be within the range of 0.5 volt to 1.0 volt,
and
• for colour cameras, the minimum colour burst level at each video input must be at least
100 mV.
If the video level is low, cable compensators or video line drivers should be installed at the video
source. They should be adjusted to boost the video signal to within the voltage limits given
above.
