FAQ
TL;DR: With 2 FI8904W cameras, direct pairing with a BCS CVR0801‑IV fails because “the stream is after MJPEG and the recorder supports H.264.” [Elektroda, xury, post #16921767]
Why it matters: You avoid wasted setup time by matching codec/protocol support before wiring or port‑forwarding.
This FAQ is for DIY CCTV users asking how to connect Foscam FI8904W to a BCS CVR0801‑IV for wireless preview and what realistic workarounds exist.
Quick Facts
- FI8904W outputs MJPEG; CVR0801‑IV expects H.264, so they won’t pair directly. [Elektroda, xury, post #16921767]
- Manual add requires camera HTTP/RTSP ports plus credentials; without RTSP/ONVIF it fails. [Elektroda, luk9753, post #16919795]
- Example BCS port set: TCP 37777, UDP 37778, HTTP 8080, RTSP 5554. [Elektroda, prodaniel, post #16919826]
- FI8904W UI shows only HTTP port; users couldn’t locate any RTSP setting. [Elektroda, prodaniel, post #16919826]
- Practical workaround: view FI8904W in Foscam’s own app, not iDMSS/gDMSS. [Elektroda, jpl, post #16922151]
Will a Foscam FI8904W work with a BCS CVR0801‑IV over Wi‑Fi?
No. FI8904W streams MJPEG, while the CVR0801‑IV expects H.264. “The stream is after MJPEG and the recorder supports H.264.” [Elektroda, xury, post #16921767]
Does the FI8904W support ONVIF or RTSP out of the box?
Users reported only an HTTP port in settings and could not find any RTSP option. That blocks ONVIF/RTSP adds. [Elektroda, prodaniel, post #16919826]
How can I check if my camera exposes ONVIF and find its stream path?
Use ONVIF Manager on a PC in the same subnet. 1. Set camera IP. 2. Scan in ONVIF Manager. 3. If it appears, note the URL and port, then add that port in BCS. “Try to add a camera in BCS after this ONVIF port.” [Elektroda, jpl, post #16921447]
I set correct IP, gateway, and DNS. Why can’t the recorder see the Foscam?
Because codec support matters more than network reachability. FI8904W is MJPEG, and the recorder needs H.264. [Elektroda, xury, post #16919819]
Can manual adding with ports and credentials make FI8904W work?
Manual add requires HTTP and RTSP ports plus login. Without RTSP or ONVIF, the attempt will still fail. [Elektroda, luk9753, post #16919795]
Do I need router port‑forwarding to add the camera on the same LAN?
No for local pairing; the blocker here is codec incompatibility, not NAT exposure or forwarding rules. [Elektroda, xury, post #16921767]
Can iDMSS/gDMSS show the FI8904W stream directly?
No. Use the Foscam app for preview instead. iDMSS targets Dahua/BCS streams. [Elektroda, jpl, post #16922151]
What are realistic workarounds if I must preview the FI8904W?
Use the Foscam app for standalone preview, or an NVR that accepts MJPEG. App mixing with iDMSS isn’t supported. [Elektroda, jpl, post #16922151]
Will updating the BCS recorder firmware help cross‑brand compatibility?
It can help with ONVIF interoperability. Dahua/BCS added many improvements in recent updates. [Elektroda, luk9753, post #16919795]
What port settings were shown working on the BCS side in this case?
Example shown: TCP 37777, UDP 37778, HTTP 8080, RTSP 5554 on the recorder. Camera showed only HTTP 8081. [Elektroda, prodaniel, post #16919826]
What do MJPEG and H.264 mean in simple terms?
MJPEG sends each frame as a JPEG, using more bandwidth. H.264 compresses video efficiently. The recorder needs H.264. [Elektroda, xury, post #16921767]
Does using Ethernet instead of Wi‑Fi change compatibility here?
No. The user tested wired and wireless with no difference. Codec mismatch still blocked adding. [Elektroda, prodaniel, post #16919748]
How many cameras were planned in this setup, and why does it matter?
Six total (4 existing + 2 FI8904W). Capacity planning matters if you swap to H.264‑capable units. [Elektroda, prodaniel, post #16919183]
Can an older DVR that supports MJPEG ‘bridge’ the FI8904W into the BCS?
Users asked this, but no success path was confirmed. Mixing firmware images across brands is not advised. [Elektroda, prodaniel, post #16922068]
ZXTECH NVR with Dahua DH‑IPC‑HFW4800EP works on LAN but not remotely—what now?
The post notes LAN preview works, but no P2P or remote view. Check NVR’s remote method and app pairing. [Elektroda, ralfik12345, post #17058088]
