live streaming to a cell tower

Can someone tell me what options there are to set up a live streaming camera in a remote location with direct line of sight to a Telus (Canada) cell phone tower which is about 1...

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? 

Doug

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

Hello Wildlabs Community, Does anyone have advice on where to start with arboreal camera trapping and the surveying intensity needed to detect arboreal species? I found a this...

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!

Maybe the alkaline battery will be an option in the future, which is more environmental friendly.

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

Hello everyone, I'm Patrícia and I'm currently working as a reseach assistant in Príncipe island. One of my tasks here is to use artificial nests to...

10 0

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

 

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

We are exploring rechargeable battery options, particularly for Cuddeback XChange Color (C1) models. These cameras use 8x AA batteries, and ideally need a charge of 1.5V...

9 0

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.

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 

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!

Hi

I just tried and works great, I will include it in my workflow. 

Thanks for your work!

Wide angle camera trap

I am looking for a camera trap model with a wide(r) angle lense than the conventional ones offer. The model needs to be able to function properly in a tropical forest environment...

12 0

Important considerations raised by Peter!

In my case it was not important though, as I was using the trap camera in timelapse mode.

 

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.

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!

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? 

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).

Nice! I'm building an esp32-cam with a Pi Zero server and I have the photos sending to it now. The last step is to build a housing for it and get it outside to capture some photos of the bears coming out of hibernation. Should be fun! I'm hoping to download photos from the camera over 1km away from my house, while sipping tea haha.

Akiba I have used ubiquiti loco m5 to broadcast internet with great success when I was setting up internet for a park for a 10k run I was able to get atleast a mile with no issues with internet 

not discorcuaged just looking  to piggy back off of a local wifi and be able to connect to a diy camera trap and be able to either do live video feed or capture a pic and then with a program I create send it to email or txt message 

the place I am looking at I can get almost a mile in distance but the problem is the power it would have to be some kind of solar power don't want to have to change batteries ever other day 

Something I'm working on that might work well for you and is super affordable at about $30 per camera.

ESP32-cam (not super high quality photos though) with a motion sensor and it sends the photos to a PI Zero W that can be accesses at any time via wifi. I'm using the TPlink portable but have found that WemosD1 boards and upgrading the firmware to be able to do wifi repeaters works well.

Here's the camera I'm using:

https://starairvision.com/esp32-cam-motion-camera-with-date-and-time/

I'll make a post on here when the full project is built and I've tested the range. The repeaters use something called mesh networking. You can have a number of them in a row to get the camera out into the forest. Or if you have lign of sight you can use a signal booster and or a directional antenna.

Thanks Ryan would like to hear more about this, the project look awesome what distance are you getting from your wifi router

One barrier that was discussed in the presentation was the "risk" or uncertainty of a payoff when talking to potential funders. It seems to me that the "risk" factor of collaborations like this, for funders, would be analogous to the investment and payoff when developing a genomics program. Relative to traditional field research, it takes a much greater investment in time, with different expertise, to create a reference genome for a species of interest and then pull SNPs, etc. Nevertheless, funders seem to recognize the potential for genomic research and genomic tools. Do you think that greater openness to “risk” in conservation genomics results from closer intellectual proximity (i.e., molecular biology vs organismal biology), or to conservation genomics being a more mature field (i.e., more examples of success), or to other factors? If intellectual proximity is a key factor, then conservation tech collaborations will continue to face this barrier, but if lack of successful examples are a key factor, then perhaps this barrier will become less of an issue for conservation tech in the future. Thoughts?

Hi. Just watched the Youtube version (I'm in the unable to watch live hemisphere) and wanted to say that was a great talk. I wish it could have gone for another hour. I liked hearing about the issues and concerns from Melanie on the biology/ecology side. Also could totally relate to what Ed was talking about from the tech side about how it's difficult to have long term collaborations since there isn't really a conservation technology career path at the moment. 
I think one of the things we're trying to do with courses like Build Your Own Datalogger is to get people involved in wildlife/conservation side more comfortable with the tech. The goal is to hopefully build a shared repository of technical knowledge that people in the wildlife community can contribute to and benefit from.
