PULSE FXI6 Series Installation Guide 
17 | P a g e  
NOTE: The users might need to configure the Primary Stream and Secondary Stream properly. 
Sometimes, the user might like to watch the live video stream from the web GUI in low resolution mode 
while recording a copy via “Surveillance System” software in high resolution due to the limitation of 
internet bandwidth. In this case, for example, primary stream can be configured to have better 
resolution, and then the users can use primary stream to record while watching secondary video 
streams. 
Audio Settings 
Preferred Audio Codec – The FXI6 supports up to 3 different Vocoder types, a-law 
(PCMA), u-law (PCMU) and G.726. The audio can also be turned off by switching the setting 
to “Disabled” 
Power Frequency - this setting should match the power frequency used in the country to avoid flickering
