Hi @P_S 

Thanks for reaching out to TP-Link Business Forums.

May I confirm if you setup the same time zone on both your NVR and Tapo cameras? Please make sure your NVR and Tapo cameras are on the same time zone.

Also, may I know how do you manage the NVR? Personal Edition or Enterprise version VIGI APP?

Can you view the live feeds on the VIGI APP?

  @Gabriel-TP 

Not enterprise edition.

Initially the NVR was on UTC and the cameras were on +5. I changed the NVR to +5.5 and the problems started thereon. Couldn't find a way to change the camera timezone through the tapo app.

Only 1-2 random motion notification are being registered on the Vigi app and NVR recordings. The cameras are logging motion/people/vehicles etc as it should via Tapo app (which isn't helpful to me).

Note I did earlier reduce the sensitivity of motion detection on the NVR but it was working fine until I changed the time zone setting. But I can't find an option to adjust sensitivity via the vigi app to test if this is part of the problem.

Also is there a way to get the NVR to process smart object recognition on its own? I've read that the Tapo cameras don't send events via onvif event info. But I've noticed that the Vigi live view has smart green frame on objects such as people and vehicles. So is there a way for the NVR to do smart object recognition on its own?

Thanks for your help.

Hi @P_S 

I'm not professional in Tapo device. But if you want to change Tapo time zone, here might be the tip:

For devices that do not support changing the Time Zone in Device Info:

For cameras/doorbells, open the Tapo app > tap the Device Card > tap the gear icon in the top right to enter the device settings page > tap "Device info" > "Time zone" to choose the correct time zone.

The ONVIF standard defines an event handling mechanism. When a third-party IPC supports ONVIF, it usually has a built-in motion detection function. Once the IPC detects a change in the image locally, it generates an event and sends this event message to the NVR via the ONVIF protocol. Upon receiving the event, the NVR executes preset actions (e.g., recording, alarm push, pop-up window).

Therefore, the NVR itself cannot do samrt object recognition on its own.

  @Gabriel-TP I can confirm that cameras and NVR are on the same time zone (somehow Tapo app notifications have an incorrect time stamp- perhaps a bug).

Thanks for explaining about the Onvif protocol and events. I have a tech background. From my understanding, the Onvif protocol supports sending event tags that include "Human", "vehicle" etc via XML. The camera supports this and is apparently sending the events. The NVR is also supposed to support event handling (see screenshot of compliance certificate) but for some reason the NVR isn't processing/receiving them. So that would mean the NVR is not fully Onvif compatible as it is meant to be and/or TP link has chosen to limit the compatibility of its NVR to only Vigi cameras for event handling beyond basic motion. This would be disappointing as we purchased the system after seeing this Facebook post and video from TP Link which said that Tapo cameras work with Vigi NVRs: https://www.facebook.com/share/v/14dPZnCNQg8/?mibextid=wwXIfr

Hi @P_S 

Correction:

Currently, we do have two NVRs - VIGI NVR2016H-16MP(UN) 2.0 & VIGI NVR2008H-8MP(UN) 2.0 - support AI By NVR function. The IPC only needs to send video data to the NVR, and the event detection is implemented by the NVR. How to enable the AI by NVR feature for detection on VIGI NVR | TP-Link

It only supports four event types such as motion detection.

However, your NVR1008H does not support this feature.

IPC and NVR Time are usually set to use NTP and automatically obtain the same time from the same NTP Server. Please check if the time zone of the NVR and the IPC are consistent. You may screenshot the time settings on both NVR and Tapo IPC to us.
Check if the toggle for Time Verification under NVR Network > Network Service > Onvif is enabled. If it is, then the NVR will verify the time in the Onvif message. If the time error exceeds 1 minute, the message will be discarded.

Please provide us with the Tapo hardware and firmware version.

If this still not help, I will then create a ticket on your behalf. Then please provide your NVR and Tapo IPC access to us, along with the packet capture during adding the Tapo to NVR and the Tapo triggers motion detection but without any events on the NVR (please indicate the IP addresses of both devices).
