Operation Manual

> TEMPERATURE FAILURE : This event occurs if the internal temperature of the NVR exceeds the allowed range.
Then, the NVR will not operate normally. If this is the case, check the following and take an adequate measure.
- Check if the ventilation of the NVR is clogged with foreign substances. If so, remove them.
- Keep the NVR away from a heat source such as a heater. Install it in a flat, lower area with good ventilation.
- If the problem persists, contact the retailer or service center.
> POE FAIL EVENT* : This event occurs if the power consumption reaches the specified level of the power supply
capacity of the NVR and the External PoE Hub*.
*Only for the 16Ch NVR model GRI-K4416A.
NOTE: To monitor the normal operation of the NVR, it is recommended not to change the buzzer output settings
of the fan failure event and the temperature failure event.
Network :
> TROUBLE IN INTERNET CONNECTION : Occurs if the Internet connection to the NVR fails. If you do not want to
connect the NVR to the network, leave the <Action> item blank.
> FAILURE IN REMOTE LOGIN : This event occurs if a remote client fails to log in due to an invalid ID or password.
You can specify the number of failed registrations for triggering the event by clicking on the ‘Arrow Down’ button.
> FAILURE IN DDNS UPDATE : This event occurs if the NVR tried to update the DDNS address but failed.
NOTE: If the DDNS address fails to be updated, the NVR may not connect to a remote client. If this is the case,
enter the IP address from the client side to allow access from the NVR. This is just a temporary measure. For the
IP address, move to <EXTERNAL IP ADDRESS> and check the <EXTERNAL IP ADDRESS> from the <NETWORK>
window.
ATTENTION: Please be aware that the <EXTERNAL IP ADDRESS> can change at any time in a dynamic IP
environment.
