Notice about construction of the surveillance system using this unit
• This unit can be controlled by the external devices via RS-232C terminal or LAN terminal. This unit can also be used to
control external devices via external terminal, RS-422/485 terminal, or RS-232C terminal. Owning to these functions,
this unit fl exibly applies to the high grade security system, but the whole surveillance system may be affected by the
malfunction of this unit or the external devices depending on the setting contents of this unit, the connection with the
external devices, or combination between this unit and the external devices.
• When configuring a surveillance system using this unit, it is recommended to confirm first that this unit operates
normally with the other devices connected.
• It is recommended to copy or back up the important recorded contents.
• Damages rising out of any operational error of the surveillance system or loss of the recorded data or any other
damages because of any user malfunction of this unit are not covered.
• Do not use the notifi cation function of this unit for making critical judgement nor any purpose related to human lives.
• When this unit cannot recognize the external device which is being used for recording due to the power failure,
decreased voltage, or other failures, the recording point may be moved to the internal HDD of this unit or the other
external HDD. To prevent occurence of such problem, it is recommended to use uninterruptible power supply.
• If the power plug is disconnected or the breaker switch is turned off during recording, HDD may be damaged or
playback of recorded data may become impossible.
If the breaker switch is turned on and off everyday, set the timer recording to be performed only for the period that the
breaker is on and do not turn off the breaker during recording.
• It is recommended to check periodically that recording is perfomed successfully by playing back the recorded data.
There may be cases when the unit's built-in motion detection function does not operate properly due to external
condition, video input signal, or other factors.
The user will not be indemnifi ed for problems (e.g., recording failure or playback failure) that occur with either the unit or
a connected device during operation. It is recommended to back up the important recordings regularly as a precaution
against possible breakdowns and accidents.
