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!

Dealing with Cows whilst camera trapping
5 August 2022 11:17am
9 August 2022 12:02am
Hi David,
Harold is correct. Cattle do like to use anything to scratch against. They are also pretty inquisitive.
Cattle don't like shadows or flowing rubbish/ material. So attach a flag post near the camera or build a cage around it. Yet with a cage, cattle will most likely rub up against it.
Never ending cycle of the scratching vs what you don't want moved
9 August 2022 3:22pm
I like the idea of supplying them with a scratching post solution, I will look into that. Thorns/gorse is also a great idea.
Thanks very much for the suggestions! I will let you know what works!
9 August 2022 3:24pm
Hi Kim,
Thanks for the response. I think they can hear our cameras clicking when they are set off and they come to see what is happening so I would totally agree with the inquisitive cows!
I will try the flag idea as building cages is just not going to be practical with soil depth.
Thanks for the suggestion!
Cheers
Dave
Can deep learning identify seabirds? (species, within-species, individual)

— Damien R. Farine (@DamienFarine) May 27, 2022
Individual identification needs tens of pictures per individual of known individuals as training data, which will be the challenge here.
Absolutely feasible, to learn how to train a CNN to identify species from satellite images I did a few tutorials on ID species from photographs. With the right training dataset it should be fairly straightforward. For individuals? Easier on species with clear markers (fins).

Hi Jitendra.
If they are still images, many people are using Megadetector to analyze their images. I'm not sure how it will do in species classification, but it can tell you if there are images of interest in the shots. Others here can probably give you more detailed instructions on how to use it to batch process camera trap images.
2 August 2022 10:24am
Have you considered creating a Kaggle competition? If you already have lots of images, and some that have been labelled, then this could be a good way to get people working on a solution

9 June 2022 1:22pm
Hi Meredith
We used some cheap Browning trail cams to record grey seal behaviour on the Farne Islands over the last autumn as a timelapse. We recorded an image every 1 min during the pupping season, which you probably don't need not need to record glacial melt, and they performed brilliantly. The batteries (8 x Lithium AA) lasted the whole of the season, from Mid October until the end of December, but we had to periodically swap the 32Gb SD cards as they would fill up after about 3-4 weeks. We also had to tape over the movement detector as that function still works even when timelapse is in operation.
At the end of the season, we switched to every 2 min to pick up the final waifs and strays and to get some info on the moult, but, due to logistical reasons, we didn't have the chance to replace the batteries, nor could we change the SD cards. Even so, one of the cameras lasted until mid April i.e. over 6 months on a single set of batteries. We only had one of the eight cameras break and that was because a seal went over the top of the camera wrenching it from is anchorage point and eventually into the sea! It did get washed up but was in a sorry state after all that!. The others were all working perfectly and were ready for the seabird season.
Happy to provide more info if you need it

Hi Meredith,
Here's a little more information about the Arribada cameras. They are solar powered and received enough power in the Antarctic winter continue photographing. We programmed them to take an image every hour, which might frequent enough for you to monitor glacial ice. Even with 3 years of continuous monitoring, the memory card did not fill up. I think they are priced a little higher than 90 USD, but they can stand alone without maintenance for a long time. Depending on how remote your field site is, that might be beneficial.
We can send over some of the sea ice images we collected. They're fun and interesting to look at if nothing else.

How do you store your camera traps?

I store my Cameras in one gallon plastic bags with a zipper lock. Most cameras will fit in that size bag. There is a note card that goes in the bag, The note card lasts longer in the bag and does not smear which it will if you write on the outside and is very important if you are running a lot of cameras. You can make a nice note card with a word processor and lay out everything you want to note. The Notes can be whatever you want to track but the most useful is the brand and model, the date the camera was purchased, The Date it went into the storage bag, Notes on if the camera has been updated. The camera number, the password if the camera needs a password, The person who put the camera in the bag with their full name and the date, A note on how the camera did on it's last deployment, Camera works fine, YES, or whatever might be wrong is listed. I would also list any special features that the camera can perform, such has WIFI enable, Cell Camera, etc. I also make sure the Cameras number is easy to see on the card. When the cameras go out they should have a camera number on the inside of the camera so you can track it in your field notes and make sure all the bags come back from deployment so they are ready for when the cameras come back in from the field.
The batteries are removed from the camera, When I bring a camera in from the field I test each battery with a battery tester. If all the batteries are still good that information is noted on the bag card that the batteries were tested and their strength. Keeping the batteries with the camera keeps you from mixing batteries of various strengths. Remove any bad batteries and note if a new one has been added. If you decide to replace all the batteries, Note on the card that they are NEW and their strength because all new batteries should be tested to make sure you did not get a bad one. If batteries are not available put that on the Note card, NOTE, removing the batteries will usually require all the settings to be redone, I still put on the note card, CAMERA NEEDS NEW SETTINGS.
I also put in the SD Cards, with SD size on the Camera Card. Some of my older cameras only take a 32 gig or smaller, while my new cameras take 125 Gig SD cards. If putting out a camera for a very long run I want to grab one that can take a large SD card. I usually have two SD cards for each camera so they can be swapped out but keep the same cards. Put on the Camera Card that the SD card should reformatted before the next deployment or you can reformat the SD card before the batteries are removed, but NOTE on the camera card that the SD cards are formatted and ready to go. This is a good idea so you know before storage that the SD cards work.
Last I add one packet of Silica Dry packs. The bags are 5 grams. I use DRY and DRY. I got them in a 50 packet bag from Amazon, about 8 bucks. They are cheap and do a great job of removing all the moisture from the Camera, batteries, SD card, and keeps them dry for even very very long storage.
Hope this helps, when the camera number goes up the more you need to keep them organized.
17 June 2022 4:40pm
I forgot to add, I put the cameras in the bag with the doors or camera halves OPEN so the moisture does not stay in a closed camera, we want everything to stay dry.

23 February 2022 10:22am
16 March 2022 3:07pm
@TomRS @greghall and @htarold my initial (and brief) tests with the microwave sensor (same as this one: https://wiki.dfrobot.com/MicroWave_Sensor_SKU__SEN0192) I have suggest it's really sensitive to movement at fairly close range (~2m or less). Whilst this is impressive (like, it can detect my finger moving a few mm @ ~1-2m), it suggests that in order to avoid a lot of false positives/blank images, a fairly high tolerance or threshold would have to be set in the code. This will take a bit of trial and error to get right I reckon. Even though it has an in-buit potentiometer to toggle 'sensitivity' (equates to distance), even at the lowest setting, which is what I have it at, it's still really sensitive out at several metres. It definitely does appear to have an ability to tell the difference between a 'one off' or superficial movement, and more consistent movement that might be expected when an animal moves through an area. Maybe a combo PIR (interrupt) and microwave sensor (double checks after wakeup) could be a goer...although that could be a bit slow...Anyway, thought I'd share...
