# NVR HiWatch DS-N316(D) Fix Progress
|
|
|
|
## Problem
|
|
All 13 XM cameras (53H20AF) cycle online/offline every ~30 seconds on NVR.
|
|
NVR IP: 192.168.1.123, FW: V4.76.015 build 250210
|
|
Network: 192.168.1.x (Знаменское, через Cudy router 100.70.54.204 Netbird)
|
|
|
|
## Camera List
|
|
1:192.168.1.42, 2:192.168.1.69, 3:192.168.1.101, 4:192.168.1.40, 5:192.168.1.64
|
|
6:192.168.1.70, 7:192.168.1.20, 8:192.168.1.58, 9:192.168.1.57, 10:192.168.1.56
|
|
11:192.168.1.63, 12:192.168.1.47, 13:192.168.1.41
|
|
|
|
## Key Discovery: DVR-IP Protocol Works!
|
|
- XM camera admin password: empty (""), XM hash: tlJwpbo6
|
|
- Login: EncryptType=MD5, PassWord=tlJwpbo6, UserName=admin, port 34567
|
|
- msg_id 1000=login, 1042=config_get, 1040=config_set
|
|
- TCPMaxConn: 10 (connection limit theory WRONG)
|
|
- RTSP accepts ANY auth (Basic, no auth, wrong creds) — auth NOT the issue
|
|
|
|
## What Was Tried & Failed
|
|
- Disabling sub-stream (VideoEnable=false) → NVR still tries stream 102, gets accessFroDeviceStreamFailure
|
|
- Anonymous RTSP (Anonymity=true) → still cycles
|
|
- HIKVISION protocol → online=true but no video (can't get device params)
|
|
- Custom Protocol → badXmlContent (400)
|
|
- streamType=main → NVR returns 400 (only "auto" supported)
|
|
- PUT /ISAPI/Streaming/channels → notSupport
|
|
- ONVIF DeleteProfile → camera ignores
|
|
- SetVideoEncoderConfiguration → camera closes connection
|
|
- Different passwords → no effect
|
|
- MTU change → no effect
|
|
|
|
## Current NVR State
|
|
- CH1 still has 192.168.1.42 configured (camera is FROZEN — ports closed, pings OK, needs power cycle)
|
|
- All other 12 cameras are alive
|
|
|
|
## Root Cause Investigation
|
|
- NVR error: accessFroDeviceStreamFailure (stream access fails)
|
|
- RTSP DESCRIBE works fine from client (200 OK)
|
|
- Camera accepts any RTSP auth
|
|
- Issue may be in SETUP/PLAY phase or RTP transport
|
|
- NVR does ONVIF → gets RTSP URL → tries DESCRIBE/SETUP/PLAY → fails after ~20-30s
|
|
|
|
## SSH Tunnels Pattern
|
|
```bash
|
|
ssh -o StrictHostKeyChecking=no -o ConnectTimeout=10 -o ServerAliveInterval=10 -L LOCAL:REMOTE_IP:REMOTE_PORT root@100.70.54.204 -N -f
|
|
```
|
|
|
|
## Key Scripts
|
|
- /root/nvr_clean_test.py — full test: DVR-IP config + NVR add + monitor
|
|
- /root/xm_full_explore.py — explore camera settings via DVR-IP
|
|
- /root/xm_disable_substream.py — disable/enable sub-stream
|
|
- /root/xm_fix_rtsp.py — change RTSP anonymity settings
|
|
|
|
## Next Steps
|
|
1. Do full RTSP session (SETUP+PLAY) to verify stream actually works
|
|
2. Check if NVR uses TCP or UDP for RTP transport
|
|
3. Maybe try adding camera with empty password ("12345678" - 8 char minimum for NVR)
|
|
4. Consider: maybe NVR ONVIF GetStreamUri returns different URL than direct ONVIF query
|
|
5. Camera 192.168.1.42 needs physical power cycle
