Q: QuestionIt says AI powered. I have has this system now for over a month and there is no AI at all. If there was then it wouldn't tell me a human has been detected when a flying bug goes past or a little cat walks in frame. So what exactly is the AI doing?
Asked by KnucklezR.
- A:Answer Hi Knucklez, Thank you for reaching out, and I’m sorry to hear about your recent experience. Our AI Powered Sentinel System is designed to detect humans. To ensure this feature is enabled, please right-click on your NVR screen to view the menu > select Alarm > Motion Detection. Make sure AI Detection is toggled on, and set the sensitivity to Medium (this is our recommended setting). When AI Detection is enabled, the system focuses on human detection. You should also see a red box appear around detected humans if Human Box is enabled.

Q: QuestionIn the event that I cannot connect all cameras directly to the NVR, can I connect them to a PoE switch on the same local area network as the NVR?
Asked by cpuman216.
This question was asked about the related product: Defender - AI POWERED Sentinel 4K Ultra HD Wired 8 Channel PoE NVR Security System, 6 Metal Cameras & 1TB HDD - White
- A:Answer Hello, We don’t recommend connecting the cameras through a PoE switch. The cameras are designed to receive stable, dedicated power directly from the NVR, and using a switch can cause power inconsistencies, which may lead to cameras disconnecting, not powering on properly, or reduced performance. For best results and reliability, we recommend connecting each camera directly to the NVR. Best regards, Jenny | Defender Customer Experience Expert
