Thank you for your information.
I understood already this type less speed than fiber optic.
I think this is enough try to use CCTV and FS.
Because CCTV and FS supplier didn't show to us requirement spec.
I want to contract to this one and try to use.
If it's not enough when we will consider for this (CCTV and FS) again.
I want to discuss with you on next Monday.
pls waiting to decide to it.
Thank you very much for your arrangement.
