Snapshot does not work on Amcrest firmware V2.400.AC02.15.R.20170731 #102

tchellomello · 2019-01-07T22:38:43Z

Fails on:
2.400.AC01.15.R
2.400.AC02.15.R.20170731

See: #86

Hello, I use a dahua nvr, and where an http call to snapshot.cgi used to work (yes with digest authentication) on an older nvr, I have now replaced it, and the api seems quite different. There was also a call for ConfigManager.cgi&getConfig?name=ChannelTitle that also now fails....but I found in fiddler that there is an RPC2 call that is made now with json that replicates this function, eg:

'{"method":"configManager.getConfig","params":{"name":"ChannelTitle"},"id":51,"session":135423203,"params2":"000001bc3115e090000017d2"}' http://nvrip/RPC2

Hoping that someone might be interested in working on this, as is may be similar for the snapshot call, that may have moved to the rpc2 method also.....

I suspect the issues seen here and on #86 have been fixed by HA PRs 21664 & 21720 and amcrest release 1.2.5. FWIW, my camera has version=2.400.AC02.15.R, build:2017-07-31, and it works fine with the above PRs.

@pnbruckner , can you try that on yours?

@pnbruckner using the latest merged #108 still the same problem on my camera. Maybe is something with my camera.

pnbruckner · 2019-05-20T21:18:47Z

The 1.5.1 release just made should fix these incorrect reports of error 401. However, if the snapshot command doesn't work, there will just be a more reasonable error, which is a connection error. There are two reasons I know of why a snapshot command will fail. The first is trying to issue two snapshot commands simultaneously, e.g., from two different hosts. The one that starts first should succeed, but the second may result in a "connection closed with no response" type error. The other is if the snapshot quality is too high. This I believe can cause an error 500.

Since this issue is fairly old, and there have been several updates to this package, as well as the HA amcrest component, I'm going to close this issue. Feel free to reopen if necessary.

BTW, I'm also working on a new HA amcrest component release that should significantly improve its overall error handling, especially if/when the camera goes "off line."
