Dahua Dvr is working but fan are not work so after some time will
dvr dsp ic fail.
because customer and cctv engineer dont know about fan are
working or not so will dsp ic fail of dvr. that dvr is not repairable.
most of dahua dvr are use plastic saft in pcb fan. so will
create problem in dvr.
Restart problem, Hdd problem, Playback problem, and sometime
no display.
if your dvr no display then first chek fan. if fan are not
work then problem in dsp. so its reparable or not, will know after chek pcb
booting.
( Note: used metal saft in this model DH-DVR5116H,
DH-DVR3116 but used plastic saft in new model )
we are installation of cctv but we are first change fan. we
are used fan of metal saft. we are not use adaptor which come with dvr but we
are use 12v, 5amp adaptor. extar fan are use in dvr for pcb cooling. if you are
used 2 hard disk 4TB in dvr then use always extra 12v,10amp smps for only dvr.
we face of problem in dahua product. like HDD problem,
Restart problem. fan problem but Hikvision DVR is good quality in market
nothing any problem like dahua.also available other brand but not good quality.
AHD dvr are also good quality in market but service problem.
we are also sale AHD dvr with service becose we are repairing on chiplevel. so
we will can give them solution. we have tie-up with local brand becose you can
sale easly and can not compair with otherbrand for price. you can sale with
your price.
