Camera traps have been a key part of the conservation toolkit for decades. Remotely triggered video or still cameras allow researchers and managers to monitor cryptic species, survey populations, and support enforcement responses by documenting illegal activities. Increasingly, machine learning is being implemented to automate the processing of data generated by camera traps.
A recent study published showed that, despite being well-established and widely used tools in conservation, progress in the development of camera traps has plateaued since the emergence of the modern model in the mid-2000s, leaving users struggling with many of the same issues they faced a decade ago. That manufacturer ratings have not improved over time, despite technological advancements, demonstrates the need for a new generation of innovative conservation camera traps. Join this group and explore existing efforts, established needs, and what next-generation camera traps might look like - including the integration of AI for data processing through initiatives like Wildlife Insights and Wild Me.
Group Highlights:
Our past Tech Tutors seasons featured multiple episodes for experienced and new camera trappers. How Do I Repair My Camera Traps? featured WILDLABS members Laure Joanny, Alistair Stewart, and Rob Appleby and featured many troubleshooting and DIY resources for common issues.
For camera trap users looking to incorporate machine learning into the data analysis process, Sara Beery's How do I get started using machine learning for my camera traps? is an incredible resource discussing the user-friendly tool MegaDetector.
And for those who are new to camera trapping, Marcella Kelly's How do I choose the right camera trap(s) based on interests, goals, and species? will help you make important decisions based on factors like species, environment, power, durability, and more.
Finally, for an in-depth conversation on camera trap hardware and software, check out the Camera Traps Virtual Meetup featuring Sara Beery, Roland Kays, and Sam Seccombe.
And while you're here, be sure to stop by the camera trap community's collaborative troubleshooting data bank, where we're compiling common problems with the goal of creating a consistent place to exchange tips and tricks!

Article and Discussion: Scale of camera trap studies
25 August 2016 11:50am
5 October 2016 3:42pm
But in answer to your question, @P.Glover.Kapfer , I haven't heard of any near this large. TEAM Network would be the closest - 17 sites, 14 countries and approximately 1000 camera traps deployed over 2000km 2 that are monitored annually. @efegraus - does TEAM Network have ambitions to be expand to this sort of scale?
@ollie.wearn perhaps you might know of some other big scale camera trapping projects?

How many cameras in a camera trap?
4 July 2016 4:32am
11 July 2016 2:55pm
Hi
In some cases you need to recognize individuals, such as in capture-recapture analysis for abundance/density estimations, or you might want an index of individuals that are detected (instead of number of detection).
If you need to recognize individuals is better if you have both flanks of the animal photographed, and even better if the animal has natural marks (such as rosettes or stripes like jaguars or tigers), but you can also use scars and general body complexion to help.
You can still make a capture-recapture study with one camera trap, but you have to choose only pictures of one side of the animal to use, and discard all the other pictures of the other side (since you won't know if are the same animal), doing that you decrease the detection probability, because now it would be the product of the likelihood of the animal walking trough the camera and the likelihood of going in the direction that you need.
Using one camera per site is a good setup for a site occupancy study, and you can even estimate abundance with the Royle-Nichols method, if your data fits it.
I hope this helps

We have just started testing an array of three cameras recording video at an African wild dog marking site. The idea is to give seamless coverage of an area larger than can be monitored by one camera, with maximum chance of detecting animals approaching from any direction. As a bonus it produces pictures of both sides. The cameras have only been out for a week, so it is too early to assess how well the arrangement works.
1 November 2016 1:38pm
We have a set of three Bushnells covering an African wild dog scent-marking site. They are at the apices of a triangle, with each camera just at the edge of the field of view of one of the others. This gives us a higher probability of detecting animals at the site, a better view of the action on at least one of the cameras, and no dead spots below each camera.
I was hoping to use two Reconyx Ultrafire XR6s on game trails at each of ten scent stations, but the cameras cannot detect animals walking towards or away from them.

Hi Steph - just to follow up on your post: @MarcusRowcliffe , James Durrant and I have been working on a bit of software to implement the "computer vision" techniques that are mentioned in that paragraph. You can see a demonstration of it in action here. It requires camera-trappers to "calibrate" their camera traps during setup (or take-down), by taking pictures of a standard object (for example, we use a 1m pole held vertically) at different distances. The calibration takes ~10 mins per location. From this, you can reconstruct the paths that animals take infront of cameras, the total distance they travelled, and therefore their speed.

I was initially thinking of dozens or maybe even hundreds of nodes coming back to a central wired connection point. I wonder if something like Google's project Loon could work in place of an on-the-ground network.
But stepping back from the tech for a moment, really the problem we're trying to solve here is being able to have remote monitoring cameras that don't need anyone to go out to change batteries or memory cards. After salaries, vehicles/transportation is the top expense at pretty much all of the conservation partners we have. Anything we can do to reduce the travel (and the time of the people as well) is huge.

So, in terms of power, does the "classic" solution with a set of solar panel cells on top of the box have some major flaws? I'm pretty sure I've seen self-powered meteo stations looking like this positioned along motorways/higways (don't remember what country or even a continent was it :-) Not being an expert in photo-voltaics, I would risk saying that a purposely-designed cell pointing up, directly at the sun, will have better efficiency than a re-purposed CMOS censor :-)
And indeed, talking to something overhead (either the baloons or Facebook's drones - forgot the name - or maybe even satellites?) would be probably much simpler than ground-based communication. If we had big enough energy budget, the communication channel would be "relatively easy" to implement...

Some camera trap manufacturers offer solar power as an add-on or option off the shelf. I agree that using the image seems like a solution looking for a problem.

@heidi.h Definitely a valid question. It looks like they have it connected to a zooniverse project, which means they are using citizen science to not only set up and maintain the cameras, but to process the data. Pretty neat.
What we do
Our main task is to get our trail camera volunteers up and running with equipment and training. Volunteers can now apply to host a camera in Wisconsin survey blocks where they have access to land (visit dnr.wi.gov, keyword "Snapshot Wisconsin" for more information). Trail camera volunteers are in charge of setting up a camera and retrieving its SD card (containing saved photos) at least four times per year. Volunteers then send the photos to WDNR to be posted on Zooniverse. By the end of 2017, we expect to have enough cameras for > 2000 volunteers to participate in the project -- these cameras will produce millions of photos each year!
While we get our trail camera volunteers set up, we have plenty of other photos to show the Zooniverse community. WDNR staff have placed over 300 trail cameras in two areas of the state now home to a species of elk (Cervus elaphus) formerly abundant throughout North America. Elk were extirpated from Wisconsin in the 1800s due to overhunting and habitat loss. Reintroduction efforts began in 1995 and continue today, and we're curious to know how the elk are doing! Classifying the photos from the elk reintroduction areas will give us great information about population size and distribution, and examine how elk presence overlaps with that of wolves--natural predators of elk.
