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!

BoomBox camera trap models?
1 June 2022 6:46pm
16 January 2023 10:41am
Hi @Freaklabs and anyone still here!
@hikinghack recently conducted an autopsy of the Browning Strike Force HD Pro X (BTC-5HDPX) camera trap that I got, and I've posted some photos in this Flickr album:
In particular, there's a close-up of the board:
An initial look by my friend @htarold suggests that it might be possible to tap into the triggering mechanism:
But I wonder if @Freaklabs has any insight into how this compares to Boombox camera traps that you have worked with??
18 January 2023 11:20am
The PIR motion sensor is at the top of the device board. You can see they are using a 3-pin analog motion sensor. From there it goes into a processing circuit. Unfortunately it looks like they built their own PIR processing circuit to determine motion so it would need to be reverse engineered to determine where to connect to.

Best Camera Trap Models Database: Input Needed

Many thanks, "mactadpole" for the promising remarks concerning the Browning Dark Ops Pro XD dual-lens BTC-6PXD:
"...we are extremely pleased with the BTC-6PXD. We went with these because they only use 6 aa batteries and they were smaller/lighter than the BTC-8A."
Given the similarity between the western Ecuador conditions you describe and those we face in Costa Rica the Browning - 180$ from Amazon where 37 reviews are predominantly favourable - sounds like the camera for us. Your 12.2.2021 report is now over a year old, however. Please, has anything changed since then? Any other candidate we should consider?
5 August 2022 2:00pm
Hi Shawn,
I am looking into camera traps to use for an arboreal project in Panama, I am really interested in your experience of mounting camera traps up trees. The photo shows an interesting mount, did you make it yourselves?
How were the seals on the Brownings? I have been tempted to go for reconyx cause they have really good o-ring seals but they may just be too pricy so looking for a reliable alternative.
Anything you can share will be useful.

Hi Tyler,
Would like to introduce you to Ceres Tags products
- Ceres Tags products come in boxes of 5, 10 and 24.
- There are some software partners such as Earthranger, Mapipedia and possibly CiboLabs that would be able to assist you with your mapping vegetation requirements
- Ceres Tag does not require any towers, base stations and infrastructure. This allows you to see any movements from the heard outside of their normal herd (boundary alerts), and you will not be disturbing any of the flora and fauna with infrastructure set up.
- For the timing you are looking at, Ceres Wild pings directly to satellite 24 times a day. For Ceres Trace and Ceres Ranch there are 4 within 24 hours. Taking into consideration, when you set up alert areas, you will get them directly to your phone/laptop via your software of choice
- Ceres Ranch is a reusable tag that has just been launched. Use it on this project, remove the tag and then use the tag on your next project
- The software you choose will assist with the history of your animal movements. Ceres Tag is integrated with 11 software partners and in-development with 18 software partners https://cerestag.com/pages/software-partners
- Understanding it is a short-term project, you would be able to use Ceres Tags products without the additional expense of setting up and removing infrastructure- towers, gateways
- With Ceres Tag, you are purchasing the box of tags and picking a suitable software to deliver the information you require. On average, a box of 10 Ceres Trace Tags, is the same as 1 LoRaWAN tower.

Thanks a million, @Rob_Appleby @Freaklabs @StephODonnell ! Apologies for the delay on my end - I was busy shifting to (and settling into life on) Príncipe island. A live trouble-shooting session would be very much appreciated, thank you! Given that it is December, and I suspect everyone will be off for holidays quite soon, would sometime in January work? The week of the 9th? Or possibly the week after, depending on when everybody is back from hols. In the meantime, I will check what we have on our field site (for future reference), as well as if we have a multimeter in our Cambridge office.
Many thanks again, and I look forward to hearing from you on when is a good time in January for this.

Cameratrap flash overexposure
25 October 2022 11:04am
4 November 2022 5:27pm
I have not used Bushnell camera traps for quite a while, so this may not apply, but most makes have a flash intensity adjustment. If you have already tried that without success then opaque or translucent tape over the LEDs will do the same job.
4 November 2022 7:55pm
We have used cut pieces of translucent milk jug plastic to make a flash attenuator. Stack as many as you need to reduce exposure and tape on.

Camera Issues
2 October 2022 6:57pm
6 November 2022 7:05pm
Thank you so much! this was great information! I will look into the SD card. The SD cards were working fine, but they have stopped. If they were incompatible they wouldn't have worked at first, right?
As for batteries, I am confused. Our photographer at work said lithium doesn't do well in the weather and temperature changes. On here it sounds like you guys are saying lithium is better then alkaline (which the user manual also says to use), who do I listen to?? And how do I find lithium batteries that fit the cameras?
7 November 2022 7:39am
Hi Britnee,
Sometimes cards do just stop working/become incompatible. It could be a firmware glitch, but it's a bit like how a USB thumb drive can stop being recognised in a PC sometimes. I'd try a good quality card no larger than 32GB and with a class 10 rating, format it in the camera and then test it. You could also try formatting the cards that previously worked and trying them again.
Lithium batteries can indeed suffer in the cold (how cold is getting there?), but alkalines are, generally-speaking, a poorer choice all around. Are you using the best quality Duracell or Energizer alkalines? They might be up for the task. You could also consider a rechargeable sealed lead acid or gel battery. They suffer a little in really cold weather (all batteries do to some degree I think), but you could compensate by getting a higher-than-necessary capacity model (for example, double what you might need for a normal deployment). You mostly just need to make or order the correct lead to plug the battery into the camera. It should say somewhere in the manual what connector it uses, but it's usually something like a 1.7mm DC plug (e.g.
CUI Devices PP-013
PP-013 CUI Devices DC Power Connectors DC Power Plugs & Audio Plugs datasheet, inventory, & pricing.
Mouser Electronics) but you'll have to double-check.
Cheers,
Rob

Feedback Wanted: Security Enclosures
19 December 2018 9:41am
15 July 2022 9:50pm
(Not sure how I missed this thread earlier).
I think different usage models lead to different security box enclosures. E.g:
1. High Risk Locations: You need the camera to be in a particular location, dictated by something other than optimal theft deterrence, for a long time. Or your site features very large animals (elephants). Here it seems like you pay the price (in weight) to make the thing as secure as possible (including on steel pole sunk into concrete!).
2. Low Risk/Exploratory: You have flexibility on where to place the camera, perhaps aimed at capturing specific animals or behavior, and can place the camera to try to make it less conspicuous to thieves. Also, you may be changing the location frequently. Finally, rules associated with the site may limit disturbance. Here, you'd like some protection, but you'd like to reduce weight and impact to the site.
We do a lot of (2). For this, we use camera-specific, relatively thin gauge, two-piece commercial steel enclosures -- e.g. from CamLockBox.com. These enclosures feature 1/4" holes in the back for securing to a tree; and methods for using a padlock and/or a cable lock to secure the camera in the box. These do a very good job protecting from most animals (bears, not elephants), and deter opportunistic homo sapiens.
13 October 2022 9:35am
Hi all,
Thank you for all your insights. I think @rcz133 has summed it up nicely: security enclosure design depends on the required usage.
I've tried to go for a design that I hope will work in most deployment scenarios. It should provide good mechanical protection from animals and if locked up properly should deter opportunistic theft as proper tools would be needed to get in.
Thanks to Cambridge Design Partnership, I now have a finished design and will be having some built for testing in the next few weeks.
The final specifications were:
- 16 gauge stainless steel.
- The enclosure is made of two parts that are easy to place together into a whole.
- The two enclosure parts fit together tightly with mechanical retention.
- The two enclosure parts are locked together by a padlock and/or a python lock.
- When using a python lock this also locks the camera into the enclosure.
- When locked the enclosure cannot be pried apart with a screwdriver or knife.
- The enclosure locking point positioning makes it difficult for the padlock to be bolt cropped.
- It is easy to place the camera into the enclosure so that it aligns with all lock points and apertures.
- The enclosure securely holds the camera in place with minimal horizontal movement using internal guides or fixtures.
- The bottom half of the enclosure with the camera inserted can be affixed to a tree with a strap or python lock before the top half of the enclosure is attached.
- The enclosure can be affixed to a tree using a strap, python lock or 1/4" mounting screws points.
- The enclosure allows water to easily exit through holes in the bottom and does not allow it too pool in the corners.
- The enclosure provides some cover above the lens aperture to provide sun screening and rain protection to the lens.
- The enclosure is powder coated in a matt colour scheme of dark green or brown for ease of camouflaging.
Once I've got the prototype enclosures I am keen to put them through their paces and do some testing to destruction to find their weaknesses.
If anyone has any tests they would like to see performed please let me know in the thread.
Thanks,
Sam
18 October 2022 2:54pm

Rainforest SigFox available for use

26 September 2022 10:20pm
Hi Roland,
This is really amazing, great to hear about your set-up! I'm just wondering what the overall cost was to set up this system? Just thinking in terms of setting up something similar in other parks and what they should expect with regard to price. Would also be great to hear about the overall effort, e.g., hours/team members required. It would be great to have this act as a blueprint for other organizations/research stations wishing to deploy a similar system within their respective national parks/areas/etc.!
10 October 2022 8:33am
Hi Rolland,
Interested too, but why did you choose SigFox (a private network) rather than LoRa (open network)?
Sigfox currently has some financial troubles that, don't know what it will become in the long term.
18 October 2022 11:55am
Hi Everyone,
We chose sigfox becuase it seems to have better range and is plug-play, whereas LoRa requires more custom programming and updating. Getting a gateway cost us $2000 for a year's lease + deposit. We covered solar power. There are also some 'minigateways' you can purchase but I don't know how they compare in range (plan to test). So far we are happy with the performance, in that it has worked consistency with no outages (once we stabilized the power supply). I think the annual costs are about $10 per tag. We are working on a paper that will describe this in more detail. So far just using for tracking tags but also looking at a trap sensor.
cheers
Roland
MegaDetector on Edge Devices ??
19 February 2021 12:30am
30 August 2022 5:05am
Has anyone tried running the MegaDetector model through an optimizer like Amazon SageMaker Neo? It can reduce the overall memory footprint and possibly speed up inference on devices like Raspberry Pi and Jetson.
27 September 2022 10:19am
Great work Luke @sheneman! Having a relatively lightweight bit of hardware to run MDv5 on will open up opportunities for many more people. The upfront financial cost of a Jetson Nano is an order of magnitude less than a computer with a beefy GPU.
I haven't used any of the Nvidia edge devices yet. Do you think it would be possible for someone to make a disk image with MDv5 pre installed to lower the entry barrier of learning a new system, installing software, environments and packages etc.?
A difficulty I have seen for some projects is not having access to or not having internet bandwidth to utilize cloud compute services. If anyone needs to churn through camera trap image processing in a remote field station this may now be possible!
10 October 2022 12:27pm
Great work, unfortunately, I'm not familiar with programming but computer friendly enough to follow a good tutorial. I was wondering if you will share your findings?
Thanks for the work.
Multi-SD card reading hubs
2 October 2022 3:46am
4 October 2022 2:04am
Good point and nice link. My USB 3.0 (errr USB 3.1 Gen 1) portable HDD gets a real read speed of 133 MBps or ~1Gbps. The theoretical max is 5 Gbps but I think the speed is limited by processor used by the HDD/USB bridge controller. Most SD card readers may be more limited even if the SD card can handle higher data rates. That may be why it could be best to just use the multi-port device from SanDisk.
7 October 2022 4:35pm
Jamie,
I have been using a 12-card Lexar Professional Workflow system for several years to process images from 24 trail cameras. The system has 4 bays, with 3 card readers per bay. I wrote software to automatically download and rename the images using metadata read from the info banner burned into the images by the camera. (Alternatively, the software can use the Exif metadata attached to the image.) The software is described in a recent Wildlife Society Bulletin:
The software is available on github:
Don't be put off by "time-lapse recordings" - it works on still images also.

Hi Pen-Yuan.
I need to revise what I said before. Browning devices within a specific model number have similar PCBs, ie: we worked with the BTC-8A for the Spec Ops Advantage. They're currently on the BTC-8E which we've found to have a different PCB. So I think the rule we're using on Browning at the moment (and most vendors) are that the model number needs to match, else it's likely the PCB is different. This also happened to us with Bushnell Trophycams. We're running into this issue now with a Boombox customer planning a Browning deployment. We're currently getting the camera trap in so we can reverse engineer the newer model and interface it to Boombox.
