Dahua cam OK with Domoticz
Posted: Wednesday 14 August 2019 18:38
Hello,
This ref from aliexpress "dahua franchised store" works quite well: IPC-HDW4233C-A-V2
For 40 bucks, the night vision is really impressive + wide angle useful.
On domoticz, OK using this snapshot URL:
cgi-bin/snapshot.cgi?
For more advanced stuff, FTP for snapshots can be a bit tricky to setup because the cam uses, after some tcpdump debug, unusual commands like ALLOC (for server to allocate size of the image to upload before doing so, a remnant of old FTP servers with storage amount of the 80's I presume) and create dated subdirectories (on top of a basedir that is the cam network name).
ALLOC command for instance cannot be used by vsftpd => had to move to proftpd (I already planned to do so to benefit from it's hiddenstore to avoid sometimes getting some partially uploaded file) + allow a few commands for directory creation...
RTSP works well with VLC but my main use is snapshots -> FTP, retrieved by a python service that checks for new uploads every 10s & compress/cypher uploads and immediately send them on a dedicated gmail account.
Only remaining issue is setup must be done using a plugin only running in IE. But possibilities on this side are also good for the price: Face recognition (like the one implemented in cameras) to increase probability of captures with someone that may be identified. Motion setup/tuning works well. For day vision with high contrast HDR is implemented on the sensor. Didin't tried, but some video fencing can also be setup to trigger event on people entering/leaving a zone.
The drawback may be for those using video capture on motion etc instead of snapshots... No avi/mp4 usual file formats but a format that looks to be dedicated for network video servers. Could not read this using VLC.
Anyway, for the price tag, it's IMO a good choice + a cam that does not need a dumb-phone app for setup (thus a cloud connection for the app to reach the cam! No way for this in my home) and can be firewall'ed to remain within one's LAN (I always block cam external access in router + setup a bad gateway IP on the cam).
Well, would be better with a clean HTML5 interface avoiding plugins like Axis but that's not the same price.
