• As shown in the table above, voltage decreases as the wire gets longer.
Therefore use of an excessively long adaptor output line for connection to the
camera may affect the performance of the camera.
…
Standard voltage for camera operation : DC 12V±10%, AC 24V±10%
…
There may be some deviation in voltage drop depending on the type of wire and the manufacturer.

3.2. Connecting to Power
■
AC/DC Power
Both of AC24V and DC12V can be used for the input power of this product.
When using other adaptor not the adaptor (DC12V/4A) provided by the company, make sure
that the specification is over AC 24V/1A or DC 12V/2A.
■
PoE(Power Over Ethernet)
PoE(Power Over Ethernet)is the function of LAN related devices, which supports data and
power simultaneously with only connection of LAN cable without separate power input cable
installation for power excitation to the product.
When connecting camera to PoE device, please connect to the device complying with PoE
(IEEE802.3af) specifications. In case non-standard product is used, it may cause performance
degradation or trouble.
Connect the terminals following the line colors below.
RED is for ALARM input, WHITE for ALARM output and BLACK for GND signal.
■
AC/DC Combined use
• In case PoE and power adaptor are connected to camera simultaneously, the power
authorized first by the product is used.
