basically our objective to interest in loop back, we need 8 channel dvr with loop back and 4 channel normal dvr, we will backup of 4 important camras location in recording in 4 Ch DVR Also. mean to say 4 cameras record on both DVR ( 08 and 04 Channel DVR ) because our corporate customer says that robber bring out the DVR also, so we will hide one 4 Ch DVR which have recording as backup of important location cameras in parallel.
Can we use loop T type BNC connector ?
请问这里哪位可以解释一下:
DVR 有带LOOP BACK 功能的说法么?我看到DVR 上满倒是有个LOOP OUT 接口?
是一样么?
哪位帮忙解释一下?不太懂这个功能具体作用是什么?
