How many days of footage can I store on the IPC-HDW3841EM-S-S2?

This camera uses efficient AI coding and H.265 compression to save space. With the maximum supported **256GB MicroSD card**, you can record approximately **3 to 4 days** of continuous 4K footage. If you use the WizSense 'SMD 4.0' feature to record only when humans or vehicles are detected, a 256GB card can store history for several weeks.

Will the 2.8mm lens on this camera allow me to read license plates clearly?

No, the **2.8mm fixed lens** is designed to provide a wide **107° viewing angle**, making it excellent for general overviews of yards or rooms. While the 4K resolution provides great detail, reading license plates usually requires a narrower lens (zoom) or the vehicle to be very close (within 5-8 meters).

What mobile app is required to view the IPC-HDW3841EM-S-S2 remotely?

To view live video and receive push notifications on your phone, download the **DMSS** app (available for iOS and Android). It connects easily via the P2P QR code found on the device, allowing you to manage the camera from anywhere.

Is the IPC-HDW3841EM-S-S2 sold here the official EU version or a Chinese import?

We stock the **Official EU version** of this model. This means you can safely update the firmware without risking region-locks, and it complies with all local standards. Apsardze24.lv is an authorized partner, ensuring you receive genuine hardware.

What warranty coverage do you offer for this 4K WizSense camera?

We provide a comprehensive **2-Year Warranty** for all clients (both Private and Business). Since our service center is located locally in **Riga**, any necessary warranty repairs are handled quickly without the need to ship the unit abroad.

Does the IPC-HDW3841EM-S-S2 come with a power supply included in the box?

No, the power adapter is not included because this is a **PoE (Power over Ethernet)** camera. Most users power it directly via an Ethernet cable connected to a PoE switch or NVR. If you do not have PoE, you will need to purchase a separate 12V DC 1A power adapter.

Can I integrate this camera with third-party NVRs or NAS systems?

Yes, this model supports ONVIF (Profile S, G, and T) and CGI, making it compatible with many third-party recorders and NAS setups like Synology. If you have a specific system you are unsure about, please contact our technical support team at [email protected] for verification.
