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.

Structured light/lidar /laser for measuring animals in camera traps and BRUVs.
4 July 2021 10:41am
17 July 2021 2:45pm
The simplest version might be a laser rangefinder, a measurement of image size, and some straightforward geometry, whihc would allow reasonable calculations of linear measurements.
17 July 2021 4:48pm
I've been wondering about rangefinding/size-measuring technologies that could be incorporated into camera traps for a long time, and am following this thread and the work of @Freaklabs with great interest.
So far I see there's stereo photography, Lidar, structured light/illumination, laser rangefinding, being suggested. I'm curious if we could come up with a relatively exhaustive list of potential technologies, then possibly discuss the pros/cons of each when used in a camera trap? For example, laser rangefinding might give precise and accurate measurements but maybe because it is an active sensor it drains the battery quickly and the laser might affect animals?
If there's interest I can start a separate thread so as to not detract from this one.

Hi Doug.
We often work in remote areas like rainforests, desert, Australian outback, etc so we often have to develop custom hardware. We haven't seen anything that fits our needs in a budget range that could accomodate the projects that we work on.
We've since gottenr requests to make the devices publicly available but are still working on finding time to document and set up the manufacturing for them.
However you may be interested in one of the designs we've been using in the Middle East and Australian outback. It's for 3G cellular communications and has inputs for a solar panel and rechargeable batteries. We're manly using it to connect periodically to a cell tower and upload data it collects from other wireless devces (LoRa) in the area. But you can also use it for streaming if your solar/battery capacity is large enough.
If you're interested us, please direct message us on WildLABS and we can discuss more and perhaps set you up for pre-release hardware. I've included some pics below:

Thanks for your quick response. I am definitely interested in your device if I understand correctly. Your device sends the camera feed to the celular network? Telus advertises 4G/5G does that also carry 3G? So I would need a camera, solar panel battery and a celular data plan?

Hi Doug.
It's actually an interesting application, however it might actually be cheaper to try and put together an off-the-shelf solution rather than go custom. There seem to be some livestreaming trailcams that might give you what you want almost out of the box. The Spartan GoLive trailcam seems like it might do this. Also other animal webcam setups seem to use a combination of WiFi security camera + a WiFi-LTE modem. This might actually be the cheaper and quicker way to go.
I do think that having a cellular streaming camera setup specifically for wildlife is a really interesting design. Trailcams are generally designed for camera trap functionality so I suspect the live functionality would be an afterthought. I'm curious if they have to deal with things like heat and recovering the stream after the communications goes down.
In our designs, we assume a very resource constrained environment, ie: no power sources, little or no connectivity, etc. So looking at a design where it's specifically expecting a power source (ie: dedicated large solar panel) and good/decent cellular connectivity with the design focus on uptime might be something interesting to pursue.
But for now, I recommend checking out the live trailcams or a wifi security cam + LTE bridge setup. And if you're interested in a dedicated solution specifically for wildlife cams, I'd love to discuss what the requirements would be. It might be super useful for wildlife orgs and parks to build awareness and improve funding,as well as benefit the research and conservation community.

Arboreal camera trapping

Hi Michelle, I've worked on a few arboreal camera trap surveys so I might be able to share some information. With other researchers we've been working on a paper that reviews the current state of arboreal camera trapping, methods, recommendations, and what to expect in the upcoming years. It's still in review, but I'm sure most, if not all, of the authors will gladly help you with any questions you might have.
I've seen footage of pangolins in canopy cameras (https://twitter.com/rewild/status/1272904442061492226), try contacting @masselouxgarou and @thereal_jayhay on twitter. If you have any specific questions, let me know and perhaps I can point you on the right path!

I just did a quick search and it doesn't look like there's a place where you can ship them in Mexico. However, at least in Mexico City, there are a bunch of collection sites for old electronics and batteries (see below- sorry the link it's in Spanish).

Camera traps in the tropics: no detection of wildlife visits
12 April 2021 9:57am
3 May 2021 9:26am
Hi!
the distance varies depending on where it's possible to position the camera, but the mean distance is around 2.5m. Which for rats might be to distant.
Unfortunately we can't install a cctv system.
Thank you.
7 May 2021 1:33pm
Hi Patricia,
I think this is likely an issue with the PIR lens positioning. The PIR has detection zones that are designed to maximise image capture of things moving a certain distance away.
A quick fix would be to have the camera trap placed directly above the nests looking straight down. I have seen someone doing this on twitter for invasive species on islands but haven't been able to re-find the tweets.
I would use a rat substitute for testing, like a tennis ball on a stick. Warm this up in the sun and then insert into the field of view and check if the camera has captured it. You could try this in different orientations and angles to see where the detection zones might be.
Best wishes,
Sam
8 May 2021 6:19pm
Hello
I understand how frustating that can be....I would try with the camera closer. 2.5m seem too far away for rat...specially that it must have some vegetation between. Also think that the suggestion of putting the camera above the nest facing down is also a great idea...
Best of luck...

Recommendations needed: Rechargeable batteries for camera traps
16 February 2021 4:15pm
9 April 2021 3:55pm
I have only used Tenergy NiMH rechargeables, these put out 1.2 V. We've used it on Bushnell Trophycam, which have 2x4 battery sets, i.e. you only need 4 batteries for it to have enough voltage, the additional batteries don't increase the voltage, they only prolong working time. So 4x1.2=4.8 V instead of the expected 6 V from alkaline batteries. I would think that Cuddeback has a similar circuit setup, so an external 12 V battery might actually be too much, as some have already pointed out. With regular NiMH batteries what's most important is to get batteries with high mAh. The ones sold commercially usually have very low mAh, so they won't last very long. We have 2400 mAh, I think, and it works reasonably well, they can last for about a month in the field, IR flash works.
9 April 2021 4:20pm
Hello Akiba
That sounds good!
Do you have a picture of the complete setup?

9 April 2021 6:10pm
While the manufacturer might claim that the camera requires 8xAA at 1.5v each, most likely it will work just fine with NiMH batteries that have nominal voltage of 1.2V.
I have used eneloops with Reconnyx cameras for a long time, as well as with handheld GPSes and a myriad of electronic devices and not once run into trouble because of the lower voltage. Your camera should have a setting in the menu to select NiMH batteries, that will prevent it from shutting down too soon.
I suggest you do your own testing - run 2 cameras one next to another on a 1.5V alkaline battery and a 1.2V NiMH rechargeable one until it switches off and check the voltage on the "empty" cell.
Your issue will likely not be the voltage of the cell, but the current the battery can deliver, as it has to recharge a capacitor in the incadescent flash light. I see that the manufacturer declares up to 20s recharge time for night photos, which is a lot. That is a downside of a colour camera.
I don't know what the best source is for batteries in SA, but if possible, get rechargeable batteries from IKEA (Ladda NiMH batteries). They are rebranded eneloops pro for around 30% less and I am yet to find a better battery for a camera trap. Otherwise, like mentioned before, eneloop pro will be hard to beat for performance and reliability.

Hi seems great and easy to use! Just a question, can the software success to identify the species or "only" categorize animal/ vehicle/human? Can we "trained" the software to detect a specific species?
thank you
13 March 2021 5:54pm
Right now the only classifications are animal/vehicle/person/empty. It cannot discern between different species.
There is no support for training at the moment -- I am envisioning something down the line but I wouldn't say that's coming any time soon.
Hope that helps!

Wide angle camera trap
17 February 2021 3:51pm
19 March 2021 2:40pm
Important considerations raised by Peter!
In my case it was not important though, as I was using the trap camera in timelapse mode.
19 March 2021 3:42pm
I agree the PIR sensor and the camera will be "seeing" different pictures, but I believe that is exactly the effect that is sought: now too much of the elephant is out of the frame when the camera is triggered, and the wide angle lens is desired so that more of the elephant would fit in the frame at that same triggering point.
19 March 2021 6:51pm
In the TrailCamPro link above (comparing FOV and Detection Angle), I see a few "panorama" camera models. For example, the Moultrie 150i or Moultrie 180 (https://www.moultriefeeders.com/catalogsearch/result/?q=panoramic) - although they are all listed as discontinued.
It seems this might be a solution for Daniela's scenario.
I'm also interested because it could offer more forgiving setup (if the subject does not travel exactly where expected.)
Has anyone here worked with a panoramic camera? What did you find to be their pros/cons?

Hi @carlybatist, thanks for the encouragement! Madagascar feels pretty Southern African to us (it's a member of SADC after all and plus lemurs are cool), so perhaps it will be the next "different" set of species that we add, or our second model. We just wanted to start off biting off a smaller chunk and get it delivered and working well, instead of spreading ourselves too thin and never getting good at or delivering anything. So sure, maybe in about 6 months or so if you have training images we can use?
We use a COCO-dataset-trained base model and then add our own curated training dataset sourced from user's images (with permission) or public datasets, but not any Wildlife Insights data.
Yes, it can do birds flying through, see below. Right now we have only focussed on bigger birds (ostrich, secretary bird, bustards, guinea fowl, vulture, that kind of thing), many of which are found mostly on the ground anyway, but otherwise they get lumped together as "Bird (Other)" until we get enough of each to train a specific species. Also apparently flying porcupine! (oops).
And don't worry about all the questions, we're just as excited to answer them!
3 March 2021 3:45pm
That's awesome! And yes it's definitely in Southern Africa geographically, but the biomes and species are so different that I imagine it wouldn't necessarily be easy to generalize your models and training data to Mada sites. Does Wildlife Insights use any of the same training data you do? Just seems like there could be options for not re-inventing the wheel since yoursand their's initiatives/goals are similar. Also, is this all terrestrially deployed images? Or do you have training data from arboreal camera traps as well?
18 March 2021 5:23pm
Hi all,
Just wanted to make you aware, if you weren't already, of this other Wildlabs thread: https://www.wildlabs.net/community/thread/1080. Petar Gyurov (@pepi ) made a nice GUI for the Megadetector camera trap detection platform that he talks about and provides links to (also on his Github).

Could you explain a bit more, do you want a measurement of length, or whole volume?
Like @wkcmark said, there are some simple solutions for measuring length fish, using stereo arrangements for example (2 cams looking at the same spot from slightly different angles). I also found this creative solution, using a single camera in a special acrylic case, that makes use of refraction indices. This, again, is for underwater systems.
If you could project two lasers at a known angle on the body of the animal like in exploration submarines, you could calculate the distance from the camera and measure the animal, although this would be a manual process.
