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!

wildlabsnetSubsea DIY Burnwire for Deep-sea BRUVS
6 December 2023 3:49am
11 December 2023 10:21am
Yeah from memory we found it difficult to get the relatively high voltage (~50VDC) and current (can't remember) in a small package, but we had almost no experience back then and gave up fairly quickly. We also found it difficult to get much help from the company if I remember correctly...
so is the problem with the nichrome waterproofing everything? I picture something like coating the nichrome in high temp grease (especially where it's in contact with the nylon line and the line itself) and encapsulating the entire thing in a semi-flexible silicone (so the line can slip out after detechment) with something buoyant to help pull it towards the surface maybe? Speaking of, how are tags being recovered (i.e. do they need to pop to the surface)?
15 December 2023 4:17pm
Hi Titus,
We've used this design/procedure for many years with our Deep Sea Camera systems, with good reliability. Not OTS but not hard to make and most of the materials come out to be inexpensive per unit. The most expensive item is the M101 connector ($25ea), but if you get them with extra length on the cable, you can essentially cut it off at the point where it joins the burn-loop and reuse that connector until it gets too short. You'd also need an F101 connector integrated with your BRUV, this connecting with the burnwire and forming the the positive side of the circuit, and a ground - our ground connection goes to a large bolt on the frame near the burnwire loop - but that connector generally shouldn't need replacement unless it gets damaged.
These burnwires generally break in 3-7min, burning at about 1Amp, ~14.5V. A thinner version of the coated wire could go faster or with less power required.
We do also employ galvanic releases as backups. I really like redundancy on recovery mechanisms! The ones we use are made by International Fishing Devices, Inc. Various distributors sell certain models of their products (i.e. different time durations) but if you contact them directly, they can also make custom duration ones for you.
19 December 2023 4:47pm
Hi Titus,
I've used latching solenoids as a release in a fresh water application. The product linked to is the one I have used, but has been discontinued (it's been quite a while). Anyway these little devices hold a plunger in place with a permanent magnet, but release the plunger when a coil is energised that counters the magnet. The holding force is not great, but more than enough to keep the safety on a mechanical trigger. The whole device can be potted and sealed (ideally under vacuum to eliminate voids). When pushing the plunger in to arm the solenoid, there is a definite click when the magnet kicks in, to confirm the locked state.
A similar device is the electropermanent magnet, which doesn't have a plunger, in fact it has no moving parts. You provide the steel piece that that this device will release when energised, as with a latching solenoid. It generally has greater holding force than a latching solenoid. I've used these in a seawater application. It's worth noting that there exist ferromagnetic stainless steels that can be used here to avoid corrosion.
Thanks,

15 December 2023 8:09pm
Hi,
This is a really late answer but I was new to wildlabs then. I have a security appliance that uses state of the AI models and user defined polygon areas of interest that generates video alerts of intrusions in typically under a second.
Although its setup to install automatically on an NVidia AI on the edge boxes of your intentions were to monitor a great deal of cameras you could also install it on a desktop with a high end GPU for very high performance. At home I use a desktop with an rtx 2080ti and monitor around 15 cameras and a thermal imaging camera (old one).
I have also tested a high end model (yolov7) on a high end thermal imaging camera image and it works fine as well.
Thermal imaging cameras are hellishly expensive though and I’ve found that new extremely light sensitive cameras like the HIKvision colorvu series almost obsoletes them in terms of people detection at night at a fraction of the cost.
If you are interested I’d be happy to show you a demo in a video meeting sometime if you like. I’m pretty sure it would meeting all your intrusion detection and alerting needs.

Hi there!,
You should definitely check out VIAME, which includes a video annotation tool in addition to deep learning neural network training and deployment. It has a user friendly interface, has a publicly available server option that mitigates the need for GPU enabled computer for network training, and has an amazing support staff that help you with your questions. You can also download the VIAME software for local use. The tool was originally developed for marine life annotation, but can be used for any type of video or annotation (we are using it to annotate pollinators in video). Super easy to annotate as well. Worth checking out!
Cheers,

Is this from camera trap images? Videos? Wildlife Insights is great! It uses Megadetector as a first pass to filter out empty images (those without animals), which you can also just use on its own. If you want to do individual re-ID, you can use Wildme. And as I mentioned previously in the comments, Zamba Cloud can work with videos. Conservation AI is another player in the game as well.

Also, take a look at TrapTagger. It has integration with WildMe.
Automatic extraction of temperature/moon phase from camera trap video
29 November 2023 1:15pm
1 December 2023 2:35pm
Hi Lucy
As others have mentioned, camera trap temperature readouts are inaccurate, and you have the additional problem that the camera's temperature can rise 10C if the sun shines on it.
I would also agree with the suggestion of getting the moon phase data off the internet.
1 December 2023 2:38pm
Do you need to do this for just one project? And do you use the same camera make/model for every deployment? Or at least a finite number of camera makes/models? If the number of camera makes/models you need to worry about is finite, even if it's large, I wouldn't try to solve this for the general case, I would just hard-code the pixel ranges where the temperature/moon information appears in each camera model, so you can crop out the relevant pixels without any fancy processing. From there it won't be trivial, exactly, but you won't need AI.
You may need separate pixel ranges for night/day images for each camera; I've seen cameras that capture video with different aspect ratios at night/day (or, more specifically, different aspect ratios for with-flash and no-flash images). If you need to determine whether an image is grayscale/color (i.e., flash/no-flash), I have a simple heuristic function for this that works pretty well.
Assuming you can manually define the relevant pixel ranges, which should just take a few minutes if it's less than a few dozen camera models, I would extract the first frame of each video to an image, then crop out the temperature/moon pixels.
Once you've cropped out the temperature/moon information, for the temperature, I would recommend using PyTesseract (an OCR library) to read the characters. For the moon information... I would either have a small library of images for all the possible moon phases for each model, and match new images against those, or maybe - depending on the exact style they use - you could just, e.g., count the total number of white/dark pixels in that cropped moon image, and have a table that maps "percentage of white pixels" to a moon phase. For all the cameras I've seen with a moon phase icon, this would work fine, and would be less work than a template matching approach.
FYI I recently wrote a function to do datetime extraction from camera trap images (it would work for video frames too), but there I was trying to handle the general case where I couldn't hard-code a pixel range. That task was both easier and harder than what you're doing here: harder because I was trying to make it work for future, unknown cameras, but easier because datetimes are relatively predictable strings, so you know when you find one, compared to, e.g., moon phase icons.
In fact maybe - as others have suggested - extracting the moon phase from pixels is unnecessary if you can extract datetimes (either from pixels or from metadata, if your metadata is reliable).
5 December 2023 10:09pm
camtrapR has a function that does what you want. i have not used it myself but it seems straightforward to use and it can run across directories of images:

Cool thread!
I will be testing Reolink Wi-Fi cameras in combination with solar powered TP-Link long range Wi-Fi antennas/repeaters later this field season for monitoring arctic fox dens at our remote off grid site in Greenland. The long range Wi-Fi antennas are rather power hungry but with sufficient solar panel and battery capacity I am hopeful it will work.
I am looking forward to explore the links and hints above after the field season.

The two cameras you mention below tick off most of the items in your requirements list. I think the exception is the “timed start” whereby the camera would “wake up” to arm itself after a certain date. Camlockbox.com provides security boxes for both.
Especially if a white flash is useful in your research, you may also want to consider the GardePro T5WF. I don’t have a lot of long-term experience with this camera, but it is one of the few that offers a white flash, and it has excellent battery life, especially for night captures. The audio can be a little flaky
I have done posts on these cameras, including a teardown. See:
https://winterberrywildlife.ouroneacrefarm.com/2022/04/10/browning-spec-ops-elite-hp5-teardown/
https://winterberrywildlife.ouroneacrefarm.com/2022/09/26/inside-the-bushnell-core-ds-4k-trail-camera/
https://winterberrywildlife.ouroneacrefarm.com/2023/11/18/gardepro-t5wf-white-flash-trail-camera/
I have heard reports that the HP5 can let in moisture in very wet environments. This may be a direct water contact type of thing, as we have never had water issues with this camera when it is installed in a lock box (US Northeast, Northwest).
We prefer the HP5 due to superior image and audio quality. That said, there is a known issue that with some HP5 cameras, with some fast (> 80 MB/s rated read) and large SD cards, the SD card can become corrupted, preventing the camera from capturing images. I address this, including a fix via firmware, in another post:

17 November 2023 9:19am
Hi Ben,
I would be interested to see if the Instant Detect 2.0 camera system might be useful for this.
The cameras can transmit thumbnails of the captured images using LoRa radio to a Base Station. You could then see all the captured images at this Base Station, as well as the camera's battery and memory information (device health). In addition, you could also change camera settings from the Base Station so you would not need to reclimb the trees to change from PIR sensitivity high to medium for instance.
The Instant Detect 2.0 cameras also have an external power port so a cable could be run to the ground to a DC 12V battery for long term power.
If you wanted to, you could also connect the Base Station to the Cloud using satellite connectivity, so that you can monitor the whole system remotely, but this will incur more cost and power usage of the Base Station.
I'd be keen to hear your thoughts,
Thanks,
Sam
Instant Detect 2.0 and related cost
16 November 2023 12:50am
16 November 2023 10:55am
Hi Kaarthika, hi all,
ZSL's Instant Detect 2.0 is currently undergoing Beta testing with external partners and so is still pre-production. We therefore do not have final pricing for the system.
Saying this, we have got a manufacturing partner fully set-up who has already completed two full build rounds of the system, one in 2020 and another in 2023. This means we actually have a very good idea of the system's build costs and what these are likely to be when we can manufacture the system in volume.
While I cannot release this pricing yet, I am confident that we will have an unparalleled proposition.
In particular, the satellite airtime package we can supply to conservationists due to the generosity of the Iridium Satellite Company means that each system can send 3,600 (25-50KB) images a month from anywhere in the world for a single fixed fee. This equates to around a 97% discount to the normal commercial rates.
We are currently very busy fundraising so that we can make this final step to scale the system.
If we can secure this funding, we hope to go into volume production by mid-2024.
Best wishes,
Sam

That's a very interesting question and use case (I'm not from deepfaune). I'm playing with this at the moment and intend to integrate it into my other security software that can capture and send video alerts. I should have this working within a few weeks I think.
The structure of that software is that it is two stage, the first stage identifies that there is an animal and it's bounding box and then there's a classification stage. I intend to merge the two stages so that it behaves like a yolo model so that the output is bounding boxes as well as what type of animal it is.
However, my security software can cascade models. So if you were able to train a single stage classifier that identifies your particular bears, then you could cascade all of these models in my software to generate an alert with a video saying which bear it was.

Hi @GermanFore ,
I work with the BearID Project on individual identification of brown bears from faces. More recently we worked on face detection across all bear species and ran some tests with identifying Andean bears. You can find details in the paper I linked below. We plan to do more work with Andean bears in 2024.
I would love to connect with you. I'll send you a message with my email address.
Regards,
Ed

Here is another metadata initiative to be aware of. OGC has been developing a standard for describing training datasets for AI/ML image recognition and labeling. The review phase is over and it will become a new standard in the next few weeks. We should consider its adoption when we develop our own training image collections.
OGC Seeks Public Comment on New Standard for Training Data for AI/ML Applications - Open Geospatial Consortium
OGC TrainingDML-AI Standard defines the model and encodings for standardizing any training data used to train, validate, and test Machine Learning models that involve location or time.

Trail cam recommendations for capturing small, quick mammals at night?

Hi @MaddievdW have you considered using a 'tunnel' to help, well, funnel, small critters into a space with a camera that makes it a bit easier for detections? A few years back, we made a PVC pipe tunnel with a protected food lure that seemed to work well with even cheapy trail cameras (and in fact, we ended up having to block some of the IR illumination using a few layers of athletic tape over the LED array). Here's a rather blurry image of a bandicoot we got:
And another of an antechinus:
We weren't that concerned with image quality, as we were actually testing an RFID logger in the tunnel also, and simply wanted to know if we got critters with no tags and what species (if possible). So one thing I'd definitely consider if you go down this path is focal length of the camera. Here's a previous discussion on a similar idea:
I guess you could always 'calibrate' it to a certain extent by just using a longer section of pipe. Here's what our set up looked like, but again, we had the RFID logger, so a camera-only version would be a bit simpler - the camera and battery was in the screw top section on the left-hand-side of the tunnel image and each entrance had RFID antennas linked backed to a logger in the same compartment as the camera:
All the best for your research,
Rob

Addressing each of the questions/issues posed:
Triggering Camera:
If you are getting triggers, but empty frames, during known visits by these lickety-split animals, the issue is the trigger speed. Looking at the Browning selection guide, for example, https://browningtrailcameras.zendesk.com/hc/en-us/article_attachments/12697703673243
I see that the Elite-HP5 models have a 100 ms advertised min trigger speed, which is slightly (50 ms) than the Dark Ops Pro DCL. This is equivalent to 2 earlier frames (at 60 FPS video), which could be significant with fast moving targets.
I have found, BTW, counterintuitively, that for Browning SpecOps and ReconForce models (Elite-HP5) that camera gets to first frame sooner when taking videos vs. when taking stills. I don’t understand this completely, but it’s a thing.
If you are not getting any triggers, then the PIR sensor is somehow missing the target. Make sure you understand the “detection zones” supported by your camera. These are not published, but can be determined with some patience and readily available “equipment” – see my post on “Trail Camera Detection Zones” at https://winterberrywildlife.ouroneacrefarm.com/2022/08/01/deep-tech-trail-camera-detection-zones/
Putting more than one camera at a site may also increase the probability that at least one triggers (and may improve lighting, see below)
If you’re consistently missing triggers, you may have to consider a non-PIR sensor. Unfortunately, this removes you from the domain of commercial trail cameras. Cognisys makes a number of “active” sensors based on “break beam” and (now) lidar for use with DSLR-based camera traps. You would also have to come up with your own no-glow lighting source, and hack the DLSR camera to remove the (built-onto-the sensor) IR filter. In our experience, these sets are 10x more expensive and time consuming vs. commercial trail camera sets, and are only justified by the potential for (a few) superior images.
The species-specific triggers and sets mentioned on this thread seem like a better option.
Avoiding daytime false triggers: All the commercial trail cameras I’m aware of have a single type of trigger sensor. It is based on a Passive InfraRed (PIR) sensor and Fresnel lens. Apps, Weldon and McNutt cover this admirably in Peter Apps, John Weldon McNutt, “How camera traps work and how to work them,” African Journal of Ecology, 2018.
These sensors trigger on changes in certain areas of the thermal field – in practice a combination of a heat and motion in one or more detection zones. They are not decomposable.
Some cameras (e.g. Browning SpecOps, and maybe the Dark Ops Pro?) allow you to set hours of operation so that the camera only triggers at night, for example. This would cause you to (for sure) miss “off hours” appearances by your target species, but would avoid daytime false triggers.
No Glow Image Quality: The good news about longer wavelength “No-Glow” flashes is that animals are less sensitive to them. The bad news is that the CMOS image sensors used by cameras are also less sensitive to the longer IR. Less signal leads to lower quality images. Others have mentioned adding supplemental no-glow illumination. An easy way to do this would be to set up two cameras at each of your sites. When they are both triggered, each will “see” twice as much illumination, and image quality will be improved. Browning SpecOps models (at least) have dynamic exposure control on video which allows this scheme to work (with only a frame or two of washout) while the algorithm adjusts exposure). For an example of this effect, see opening porcupine sequence in our video at https://www.youtube.com/watch?v=itx7KnlxKS4

Hi Maddie,
This camera has a very quick reaction time.
Shedding light on nocturnal behavior: A cost-effective solution for remote, infrared video recording in the field
20 October 2023 12:31pm
Do you or someone you love study nocturnal animals? Do you want to film behavior in infrared, but NOT spend $1k on a camera (that will die in the field anyways)? Is short battery life a constant battle? Here, this preprint will help!
To find out more, come to Variety Hour!

This is awesome - thanks for sharing Stephanie!! We actually were looking around for a low-cost video camera to augment an MPA monitoring project locally and this looks like a really great option!
Cheers, Liz
