Part 1 – Introduction

• Alarm I/O

- Out: It is the BJT (Bipolar Junction Transistor)

- open collector output. If the voltage and

current exceed the specication limit (Max load:

30mA, Max Voltage: 5VDC), the product could be

damaged. When connecting the device which

exceeds the specication limit, refer to the picture

(circuit) below.

If used with an external inductive load (e.g.

relay), a diode must be connected in parallel

with the load for protection. Otherwise, the

product could be damaged.

- In: Connect an alarm-in device to this port.

(Mechanism: Choose between an NC (Normally

Closed) type or an NO (Normally Open) type)

Connect a mechanical or electrical switch to the

alarm in port and the GND (ground) connector.

Alarm in range is 0V to 5V. In order to detect alarm

input from an electrical switch, the signal must be

higher than 4.3V from an NC switch or less than

0.3V from an NO switch and must last for longer

than 0.5 seconds.

• Factory Reset Switch

Restores the camera's default factory settings. For

more information, refer to the Factory Reset.

When inserting an , audio in/out, or RS485 connector,

hold down the button and push the connector in

through the exposed hole. Release the button and

then gently pull on the wire to ensure a secure

connection. To disconnect the cable, press down on

the button again and pull the cable out.

• Check your local laws and regulations on making

video or audio recordings. The user will be held

liable for any violation of the law. (Article 25-5 of

the Personal Information Protection Act: Operators

of image data processing devices may not operate

such devices for purposes other than as originally

intended during device installation, place such

devices at locations other than as originally

intended, or use such devices to record audio.)

• The network connector is not designed to be

connected directly with cable or wire intended for

outdoor use.
