More than two cameras at a trapping station?

[Hannah de Villiers]

Hi there, 

I am wondering if it is possible to pair more than 2 cameras at a trapping station? I am monitoring railway underpasses for wildlife usage by placing cameras at the entrances, and in some cases I need 2-3 cameras at each entrance (so 4-6 cameras at each station) in order to cover the full width of the structure's entrance. The problem is that if an animal is detected on more than one camera at a similar time, I would obviously want the sighting to be classified as "dependant", even if multiple cameras have captured images of the animal. This works perfectly for the paired cameras where only one camera is required at each entrance. 

If this is not possible - which I think it isn't - has anyone faced a similar challenge or does anyone recommend a way to "hack" this so that my 4 or 6 cameras at one trapping station are somehow linked, and the same sighting can be deemed dependent?

Otherwise I would imagine I'd have to edit the data export / report manually...

Many thanks in advance for the help and advice!

Hi Hannah,

This is possible using the Advanced menu.  The process is as follows:

1. Select a trap station, click Details and then click Advanced in the bottom right
2. Click the latest session from the left-hand menu (the one which is "ongoing")
3. Drop down the "Actions..." menu, then click "View Cameras"
4. Use the "Create Session Camera" form and "+" (on the left) to add all of the required cameras to the selected session.

Once a camera check is submitted, only the first 2 cameras will automatically come across into the next session, however media will be eligible to upload to every camera.  For reporting purposes this will work as expected where sightings are eligible to be considered "dependent".

Hope that helps,

-Chris

Thanks Chris for this earlier response. Your solution works perfectly. 

In the Library, is there a way to view photos in chronological order (by the time of the photograph, from all linked cameras at a site) vs the default sorting which appears to be by camera, and then chronologically? I want to look at all occurrences of an animal across 2+ cameras at a site in order to classify what it did (e.g. did it cross through an underpass or just approach and leave). At the moment, this is difficult as the photos of the same animal off different cameras are not showing up together in the Library. 

Thanks very much again for the help!

Hi Hannah,

This sorting in the library is not something that's supported today, though I think it makes a lot sense. I've captured this in the project backlog (https://camelotproject.atlassian.net/browse/CAM-278) and we'll look to introduce this to a future version of Camelot.

Awesome, thanks Chris. Appreciate it. 

To search the Library for a specific day, I'm getting no results when I enter the below search:

captured:2021-07-15 // captured==2021-07-15

The search works if I use [ captured>="2021-07-15" captured<="2021-07-16" ], but for some reason this more simple search above doesn't work? Probably a very stupid question, sorry!

Thanks, 

Hannah

Hi Hannah,

I completely agree about the behaviour here though sadly Camelot treats "2021-07-15" as midnight of that day, so matches only images at that time.  The alternate search you've suggested is currently the best way to match on a given day.

I've raised a task to improve the behaviour here so that specifying a day matches any image falling on that day: https://camelotproject.atlassian.net/browse/CAM-279
