 •

Audio

 -

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) 

 •

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.
