Perform the following connections according to the installation environment and application of your camera.

Basic Connections

Alarm Input/Output Terminal Connections

Before attempting the following connections, be sure to turn off all components of your system.

Improper connection may cause smoke or failures. Before attempting to connect each system component, carefully read the instruction manual that comes with it to familiarize yourself with the correct connection procedure.

### Basic Connections

#### APower Connection

Connect the power terminals (24 VAC/12 VDC) of the camera to a power supply.

###### AConnection to 24 VAC power supply

Although the power terminals have no polarity, the earth grounding wire must be connected to the GND (earth grounding) terminal.

###### BConnection to 12 VDC power supply

Note the polarity (+/–) of the power terminals when connecting the camera to a 12 VDC power supply.

Incorrect polarity may cause damage to the camera.

Be sure to use an 18AWG or thicker wire power cable.

A voltage drop may occur depending on the thickness of the power cable. If you must use a long power cable, determine the cable type by ensuring that the voltage at the 24-VAC/12-VDC terminals is within the operating range of the camera.

When using PoE to power the camera, do not use the camera's power terminals.

#### BNetwork Connection

This camera is designed so that you can use all of its functions via network operation.

By connecting the network (LAN) socket of the camera to your PC using a LAN cable, you can configure and operate it from the Web browser installed on your PC.

Use a LAN cable no longer than 100 m (109.4 yards) with the shield type CAT5 or higher.

The supported Web browser is Internet Explorer Ver.6.0 SP2 or higher, or Internet Explorer Ver.7.0.

###### About the internet connection

Port forwarding for the video port must be enabled on the broadband router.

For details on how to set port forwarding, please refer to your router's Instruction manual.

To connect two or more cameras, on the NETWORK SETTINGS screen, assign them with port numbers that are different from that of the first camera.

###### Using PoE

This camera supports PoE (Power over Ethernet). This means that you can install the camera in locations where there is no 24-VAC/12-VDC power outlet nearby.

When using PoE to power the camera, do not use the camera's power terminals.

Do not power the PoE hub or PoE power adapter until you finish connecting the camera.

AConnecting the PC and camera through a switching hub

You can use a PoE-compatible switching hub to extend the transmission distance.

For details on the extendable distance, please refer to the hub performance in the specifications, etc.

BConnecting the PC and camera through a switching hub and a power adapter

#### CCamera Monitor Connection

To perform focus adjustment with the camera, connect the supplied cable to the MONITOR OUT socket of the camera, and connect a monitor to the camera using a video cable.

After adjustment, be sure to remove the monitor cable.

### Alarm Input/Output Terminal Connections

To connect a cable, while pushing the protrusion of the terminal, insert the cable into the opening and then release it.

#### AAlarm Output Terminal Connection

Connect a buzzer, lamp, or other alarm device to one of the alarm output terminals (ALARM OUT1 or 2).

After connecting an alarm device, configure the output conditions for the corresponding alarm output terminal (ALARM OUT1 or 2) via network operation on the ALARM SETTINGS screen.

Alarm output terminal configuration is also possible via remote operation.

#### BAlarm Input Terminal Connection

Connect an alarm switch, infrared sensor, or other external device to one of the alarm input terminals (ALARM IN1 or 2).

After connecting an alarm device, configure the input conditions for the corresponding alarm input terminal (ALARM IN1 or 2) via network operation on the ALARM SETTINGS screen.

To use the alarm input terminals as Day/Night switching terminals, follow the steps below.
(This function is supported only by VCC-HD2300P/VCC-HD2300)

Under [DAY/NIGHT], set [DAY/NIGHT] to “COLOR” and select the terminal you want to use in [EXT ALARM].

On the ALARM SETTINGS screen, in [POLARITY], select the signal polarity of the alarm input terminal.

#### CAlarm Input Terminal Connection for Clock Adjustment (CLOCK IN)

You can connect an external switch to the ALARM IN1 terminal and use that switch to adjust the camera's internal clock.

To do so, via network operation, configure the [CLOCK IN] setting on the CLOCK SETTINGS screen.
