◆ Connecting to POWER
A. Power connection (Power supply: (DC12V / AC24V)
The recommended adapter specification for EL-750 is DC12V/3A, AC24V/1A over.
Please check the standard power requirement before connecting the power.
B. Power Cable (Extension)
As the table below, voltage drops as the wire is longer so that the use of an excessively
long power cable (or extension cable use) to the camera may affect the camera's
performance.

· Standard Voltage for proper camera operation is DC12V +/- 10% / AC24V +/- 10%
· AWG #24 : 10M is the maximum cable distance for proper operation.
Longer than 10 Meters, it may cause a damage to the product.
The manufacture is not liable for problems caused by an authorized
installation.
· AWG26, AWG28: It is not recommended. It causes a severe damage to the camera.
*Caution
a. There may be a deviation in voltage drop depending on the type of wire and its
manufactuer.
b. Please Do connect one camera by the input power! No other devices!
c. Please power on after installation finished.
