How can I grab a "snapshot" from the Surveillance Station Web API? What I would like to do is grab a snapshot and feed it to a web page.

Not very familiar with how the Web API works for Synology Surveillance Station (I am a newbie at programming in general). I have tried reading through the help. The web API help can be found here. [Surveillance Station Web API](https://global.download.synology.com/download/Document/DeveloperGuide/Surveillance_Station_Web_API_v2.0.pdf)

When I enter this into a browser I am expecting to get a snapshot JPG back

```
http://MyNASip:5000/webapi/entry.cgi?camStm=1&version="8"&cameraId=1&api="SYNO.SurveillanceStation.Camera"&preview=true&method="GetSnapshot"

```

Am I understanding this right? 

Instead I get this in the browser

```
{"error":{"code":105},"success":false}

```

And I get the following in the /var/log/messages 

```
2018-02-05T13:15:03-06:00 DS215j synoscgi_SYNO.SurveillanceStation.Camera_8_GetSnapshot[15020]: group_is_admin_group_member_by_uid.c:14 SYNOUserGetByUID(4294967295) failed [0x1D00 user_get_by_uid.c:129

```

Is the an authentication issue?
