-
O (Out)
: Connect an amplifier to this port (line
out). This device does not feature a built-in audio
amplifier unit and therefore requires the user to
purchase a separate speaker system with a built-in
amplifier.
- I (In) : Connect an audio source to this port. (Line in)
A built-in microphone is featured on the front. DC-

Alarm
- O (Out) : It is the BJT (Bipolar Junction Transistor)
- open collector output. If the voltage and current
exceed the specification limit (Max. Load: 30mA,
Max. Voltage: 5VDC), the product could be
damaged. When connecting the device which
exceeds the specification 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.
- I (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.
•
SD Memory Card Slot
Used to insert a micro SD memory card into the
camera. (An SLC (Single Level Cell) or MLC (Multi Level
Cell) card by San Disk or Transcend is recommended)
• Do not remove the SD memory card while the
system is in operation. Removing the card while
the system is in operation can cause the system
to malfunction and/or corrupt data stored on the
SD memory card.
• An SD memory card is a consumable product
with a finite service life. Prolonged use will
damage the card's memory sectors and result
in data loss or memory card failure. Test the SD
memory card regularly and replace it whenever
necessary.
• Cable Rubber
Foreign matter may get inside if reconnecting is failed
after removing the cable access hole rubber.
• Check your local laws and regulations on making
video or audio recordings. The user will be held
liable for any violation of the law.
• When switching over from 12 VDC to PoE as the
power source, the system will be rebooted once the
power adapter is disconnected.
• Organize the power cable so that it will not cause
people to trip over or become damaged from chairs,
cabinets, desks, and other objects in the vicinity. Do
not run the power cable underneath carpet or a rug
or plug the cable into a power outlet shared by a
number of other devices.
