FAQ
TL;DR: For BCS NVR0401-P/NVR08025M-P, motion detection lives in the cameras (typically 2–3 detection algorithms), not the NVR; browser‑based firmware updates can help usability—"it will help as much as possible." [Elektroda, jpl, post #16675519]
Why it matters: This FAQ helps installers decide when to update firmware, how to do it safely, and where to get files.
Quick Facts
- Motion detection is processed on the IP camera side, not the NVR, so NVR updates won’t fix detection accuracy. [Elektroda, jpl, post #16675519]
- A user enabled Dahua Easy4ip by flashing a “twin” Dahua firmware via web browser and then resetting to defaults. [Elektroda, bronek1307, post #16915754]
- Typical BCS service charge mentioned for help was 60 PLN (previously 80 PLN). [Elektroda, szymon122, post #16673486]
- Official BCS firmware (including P2P-enabled builds) is available on the vendor FTP. [Elektroda, mzielarz, post #17176799]
- Newer software improves browser login (reduced reliance on Webplugin) and works with newer Windows 10 browsers. [Elektroda, szydas, post #16674454]
Can I flash Dahua firmware onto a BCS NVR?
Yes, at least one user flashed a matching Dahua “twin” firmware onto a BCS recorder, then reset to factory settings. Branding changed and Easy4ip appeared. Browser upload succeeded where Smart PSS failed. Proceed only if models truly match. [Elektroda, bronek1307, post #16915754]
What are the risks of installing third‑party firmware?
“Uploading third-party software to the recorder may end up killing the device,” even if the hardware looks identical. This is a real risk with cross‑flashing. Confirm equivalence before any attempt, and have a recovery plan. [Elektroda, szymon122, post #16672075]
Will updating the NVR improve motion detection?
No. In an IP camera → NVR setup, the camera handles motion detection. One expert notes Hisilicon‑based cameras expose only about 2–3 weak algorithms. Update or replace cameras for better detection. [Elektroda, jpl, post #16675519]
How do I perform the update if Smart PSS won’t upload the file?
Try the web interface instead.
- Find a Dahua/BCS firmware that matches your unit’s parameters.
- Upload via the NVR’s web browser interface.
- After flashing, restore factory settings.
Smart PSS failed for one user; browser upload worked. [Elektroda, bronek1307, post #16915754]
Where can I download official BCS firmware (including P2P builds)?
BCS publishes updates on its FTP, which includes builds that add P2P features to some models. Use the official FTP to avoid mismatched images. [Elektroda, mzielarz, post #17176799]
Why should I consider updating at all?
Common reasons include improved browser login with fewer plugins, compatibility with newer Windows 10 browsers, and direct camera interface access from the NVR menu. These can streamline daily use. [Elektroda, szydas, post #16674454]
How do I find a Dahua “twin” for my BCS NVR?
Match on core parameters, then obtain the Dahua firmware that aligns with those specs. One user did this after Dahua support redirected him to BCS. Verify before flashing. [Elektroda, bronek1307, post #16929677]
Will flashing Dahua firmware remove BCS branding?
Yes, the reported cross‑flash resulted in “no trace of BCS” after a reset. Features like Easy4ip also appeared in the menus following the update. [Elektroda, bronek1307, post #16915754]
Do I need to factory‑reset after updating?
Plan to reset. The successful cross‑flash case required restoring factory settings post‑update to stabilize the system and expose new options. [Elektroda, bronek1307, post #16915754]
How responsive is BCS support, and what might they ask?
Call them. Experienced members report helpful staff and that helpline agents often ask, “What is wrong that you want to update?” Be ready with specifics. [Elektroda, raffin, post #16676101]
How much could vendor assistance cost?
A community member cited a 60 PLN fee for assistance, noting it had been 80 PLN before. Costs vary; confirm current pricing before sending hardware. [Elektroda, szymon122, post #16673486]
What is Easy4ip/P2P in this context?
It’s Dahua’s cloud/P2P access option that enables remote login without manual port forwarding. After flashing a matching Dahua build, a user gained Easy4ip on a BCS NVR. [Elektroda, bronek1307, post #16915754]
