AHD(Analog High Definition) is innovative technology in a new video format for

enhanced CVBS (COMET*) &HD video long-distance transmission.

High video quality on AHD 720P(1.0mp-AHD100,1.3mp-AHD720)

AHD or 1280H Video Output

Transmit video signal, audio signal and dual-way data communication signal over

one coaxial cable.

HD video transmission without video quality loss & delay

Extremely long transmission distance(500m)

The same connection structure as original analogue system without cable (Coax /

UTP) changing

Built-in IR Cut Filter

To stay abreast with the changing market demands, We launched AHD100 & AHD720 MODEL

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 )



1、Abnormal picture 2、Insufficiency 3、Lack of components

* After leaving factory (Changeable with fee )

1、Check it does not work properly for excessively high voltage burned

components

2、Man-made damage, short circuit, devices in burned ,leading to not

work

3、Changes the trigger circuit without authorization or improper

installation leading the damage

4、Using the ac power input leading the damage

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.
