Caution
* Before use, please carefully check each strip function, avoid human
damage
* This camera is only DC12V power supply, if use the ac power input
will cause camera plate burned.
* Before use, please confirm input voltage is DC12V, if want to use
higher voltage ,add an external circuit voltage, otherwise, it will cause
the trigger damage
* Please don't do changes without authorization to trigger circuit,
otherwise, it will cause the trigger damage
* After leaving factory (Changeable )

AHD Format
AHD-L Definition(TVL) much higher than analog 960H, a bit lower than IP HD 720P;
although AHD-L's resolution is only 960H, but the transmission way based on
brightness and color separation technology, so the definition and resolution
between 960H and 720P.
AHD-M Definition(TVL) equal to IP 720P, this format's definition and resolution
equal to IP 720P, this is the most popular format in the market.
AHD-H Definition(TVL) equal to IP 1080P full HD; this format's definition and
resolution equal to IP 1080P, it will be come at the end of 2014.

Essentially, there is no big difference among CVI,TVI,AHD (all coaxial HD), but
each of them have features, the biggest feature of AHD is perfect compatibility,TVI
have the best image quality, but the problem is transmission capacity is weak, CVI
is the main item of dahua, will have a good prospects for development ( at least will
get success in the dahua company).Trend:SDI will come again and these four kinds
of plans will be coexist.
