Solar panels in the tropics

Hi Tom,

I'm with Akiba, you have to test.  A collaborator has deployed solar-augmented kit in secondary jungle and some of them got enough light, and others didn't, so it can work.  The open circuit voltage of solar panels doesn't change a whole lot in dim light, but the current drops drastically.  So you would choose an oversize panel of the same voltage (or a bit higher).

Thanks

I've been intrigued by this topic. Thinking about ways you could use drones or some kind of launcher to deploy panels above the canopy. Sadly I live in the great white north so I have no way of testing any concepts. Maybe even some kind of solar balloon that could float above the canopy. Interesting design problem.

Hey Tom,
Since the output is dependent on a couple of factors such as the solar irradiance of the place, shading from the canopy, the type of solar panels (mono, poly or amorphous) and orientation of the panels, etc, I'd suggest you use a software to simulate the different parameters to get an almost accurate estimation of the output. You can try PVsyst- it has a free month trial (I haven't used it before but I hear it's great) or any other PV software :)

camera with fast trigger- and recovery time?

Hi Lars, yes it is and the picture management software I use is also able to read the EXIF data with the correct time stamp. It is just unconvenient for our workfklow, to not be able to read the time stamp right away from the picture. But it is not really an invincible obstacle. 

@Stephanie as luck would have it, I recently released some firmware for Browning BTC-7E-HP5 and BTC-8E-HP5 cameras that contains a number of feature enhancements, including the oft-asked-for seconds-level resolution on the Date/Time in the image info strip.  See my recent blog posts on the topic, which incudes pointers for where to find the firmware images.  Links below

Time-lapse cameras for monitoring nesting birds in the Arctic

Hi Chris, 

We developed a time-lapse camera for Penguin Watch that ran for 3 years straight in Antarctica, so should be able to survive in the Arctic. With your Plotwatcher did you use any supplementary solar (we do in the summer months). If not, we're aiming to upgrade the camera and introduce a lower power camera module this year, which should get you the 500k images on 4 x AA 1.5v batteries, but we're a number of months away from that build so couldn't help you right away. It would be good to keep in touch to see where you get and we can help you downstream. 

More on the current camera here; 

https://arribada.org/2021/12/16/three-years-in-antarctica-affordable-and-durable-time-lapse-monitoring

Thanks Alasdair! 

The Plotwatchers and Brinnos didn't require any solar for the 500K on 4aa batteries. We place the cams near the nest (actually at the nest peering into the nest bowl with a new design I came up with where the only thing above ground is a ribbon cable and the camera board attached to a metal rod we lag blot to the tundra, the batteries and main board are in a 1020 pelican case and buried; see below for an image of the above-ground portion of the cam and an image of a nest from a cam [if you look closely you can see one of the eggs just hatched and there are now 3 eggs and 1 chick in the bowl]). 

      

I'd be very interested in what you all are working on for the next design. How small would it be?

Thanks Chris,

Probably quite similar in size to your existing setup above, but we'd use two Li-ion rechargable batteries most likely (could be an 18500). I'll be sure to share more information later this year.

Cheers,

Alasdair

BoomBox camera trap models?

As discussed in this other thread, I've been planning to mod some camera traps,...

6 1

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.

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??

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.

I'd be happy to chat with you if you wanted! My expertise is within passive acoustic monitoring particularly. The Conservation Tech Directory might be useful for you in identifying relevant actors within the space.

My original background is in ecology and conservation, and am now in the elected leadership of the Gathering for Open Science Hardware which convenes researchers developing open source tech for science. I am not working on a specific piece of technology right now, but am happy to contribute some higher-level views for your interview if that helps.

Hi Simon, 

i've popped you an email too, but actually sharing some more information here about what you're after will mean you'll be able to get better help from our full community. 

What are you looking for in particular? It sounds like there is particular piece of software you've seen that could be useful in your work - do you know what it's called? What do you need to do - image recognition, call recognition? Alerts when calls happen or are you looking for something more detailed? The more you tell us about what you're trying to do the better we'll be able to help!

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?

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.

Cheers

New paper - An evaluation of platforms for processing camera-trap data using artificial intelligence

We review key characteristics of four AI platforms—Conservation AI, MegaDetector, MLWIC2: Machine Learning for Wildlife Image Classification and Wildlife Insights—and two auxiliary platforms—Camelot and Timelapse—that incorporate AI output for processing camera-trap data. We compare their software and programming requirements, AI features, data management tools and output format. We also provide R code and data from our own work to demonstrate how users can evaluate model performance.

New paper - Real-time alerts from AI-enabled camera traps using the Iridium satellite network: A case-study in Gabon, Central Africa

Sending real-time alerts from ecological sensors such as camera traps in areas with poor data connectivity is complex and involves integrating a large number of potentially complex hardware and software components. Our results demonstrate that these components can be successfully integrated to achieve reliable, near real-time alerts from camera traps under challenging field conditions.

Why would you want to avoid alerting the rangers ?

You don't need high tech for this; elephants leave very obvious tracks and sign. 

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. 

 

I just came across this interesting paper in which seismic monotoring of animals like elephants was mentioned. 

This is the study refered to:

Cheers,

Lars

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.

 

Kind regards,

Asiem
