Monitoring setup  in the forest based on the wifi with 2.4 GHz frequency.

I am planning to setup the network using the wireless with frequency 2.4GHz. Can I get the the data for this signal distortion in the forest area?Is there any any special...

5 0

Hi Dilip,

I do not have data about signal distortion in a forest area and with the signal you are intended to use.

However, in a savannah environment, when I put a tour on the highest point of the park, Lora signal (avg 900MHz) is less distorted than WiFi signal (2.4GHz). This is normal as a physics law: the frequency determines the wave length, and the less the length (obviously the less the frequency), the less obstructed the signal.

So, without interfering with your design, I would say that in a forest configuration, WiFi will need more access points deployed and may be more costly, and in your context, even when using LoRa, you will need more gateways than I have in a savannah.

To design the approximate number of gateways, you may need to use terrain Visibility analysis.

To design the cameras deployment, you will need to comply with the sampling methods defined in your research. However, if it is on for surveillance reasons, you may need to rely on terrain visibility analysis also.

Best regards.

I've got quite a lot of experience with wireless in forested areas and over long(ish) ranges.

Using a wifi mesh is totally possible, and it will work.  You will likely not get great range between units.  You will likely need to have your mesh be fairly adaptable as conditions change.

Wireless and forests interact in somewhat unpredictable ways it turns out.  Generally, wireless is attenuated by water in the line-of-sight between stations.  From the Wifi perspective, a tree is just a lot of water up in the air.  Denser forest = more water = worse communications. LoRa @ 900Mhz is less prone to this issue than Wifi @ 2.4Ghz and way less prone than Wifi @ 5Ghz.  But LoRa is also fairly low data rate.  Streaming video via LoRa is possible with a lot of work, but video streaming is not at all what LoRa was build to do, and it does it quite poorly at best.

The real issue I see here is to do with power levels.  CCTV, audio streaming, etc are high data rate activities.  You may need quite a lot of power to run these systems effectively both for the initial data collection and then for the communications.

If you are planning to run mains power to each of these units, you may be better off running an ethernet cable as well.  Alternatively, you can run "power line" networking, which has remarkably good bandwidth and gets you back down to a single twisted pair for power and communications.

If you are planning to run off batteries and/or solar, you may need a somewhat large power system to support your application?

 

I would recommend going with Ubiquity 2.4Ghz devices which have performed relatively well in dense foliage of the California Redwood forests. It took a lot of tweaking to find paths through the dense tree cover as mentioned in the previous posts.

How are Outdoor Fire Detection Systems Adapted for Small Forest Areas, Considering the Predominance of Indoor Fire Detectors?

How are fire detection mechanisms tailored for outdoor environments, particularly in small forest areas, given that most fire and smoke detectors are designed for indoor use?

1 0

Fire detection is a sort of broad idea.  Usually people detect the products of fire, and most often this is smoke.

Many home fire detectors in the US use a radioactive source and measure the absorption of the radiation by the air.  More smoke means more absorption.

For outdoor fire detection, PM2.5 can be a very good smoke proxy, and outdoor PM2.5 sensing is pretty accessible.

This one is very popular in my area.

You could look at WILDLABS' State of Conservation Tech research results! Shows ~⅓ of survey respondents are female (though this is obviously just a subset of the total people/women in conservation tech, the subset being those who filled out the survey).

@EstherGithinji runs some of the WILDLABS Women in Conservation Tech programs so she would have lots of insights into this!

Hello fellow Brett. Cool project. You mentioned a waterseal testing process. Is there documentation on that?

I dont have anything written up but I can tell what parts we used and how we tested.



Its pretty straightforward, we used this M10 Enclosure Vent from Blue Robotics:

 

Along with this nipple adapter:

Then you can use any cheap hand held break pump to connect to your enclosure. You can pump a small vacuum in and make sure the pressure holds.

Here's a tutorial video from blue robotics:

 





Let me know if you have any questions or if I can help out.

Cheap camera traps with "Timelapse+" mode?

Hi everyone,I have a fairly specific query about camera trap time lapse functionality. I am looking for cheap models that have something similar to Bushnell's "Timelapse+" mode,...

10 0

Thank you @mguins  and @NickGardner for your praise and addition. I had not thought of the backup possibility, but it sure is a good point, Michelle. I find it amazing how often one reads about and experiences camtrap malfunction. Even the relatively cheap ones are still quite a lot of money for what is, at the end of the day, a relatively simple piece of electronics and a plastic container.

Frank's idea of using 2 camera traps is inspired!

I've fiddled with cheap camera traps a bit, and some (most?) of them use a low power, inaccurate timer for the time lapse function instead of the accurate real time clock.  This is ok for Michelle's purpose, but not for Nick's as he needs to specify the exact time of day to trigger.

I made this interface to allow a camera trap to be triggered by an external device.  To it you could attach, say, a timer programmed to fire at the desired times, to cause a capture.  A $4 DS3231 RTC module could do the job, after the alarm times have been programmed into it with , for example, an Arduino.

Hi Nick, 

Any update from your project? did you find good price value Camera Traps?

We in Indonesia don't have local suppliers for any research grade Camera Traps like Bushnell, Browning or Reconyx. So we need to import them and the price inflated a lot even without the distributor. So, me and my team recently use the China model like GardePro or Meidase one ($40-60). Though we bought it in the US in small quantity if some of our friends travel back to Indonesia. They have more feature than typical Bushnell with same price range. The images are AI upscale, but doesn't really bother us. So I am curious if you found any good Camera Traps to recommend? Thanks!

Cheers,

Dhanu

Hi Dhanu,

Our group moved to Wildlife Insights a few years back (for a few reasons but mostly ease of data upload/annotation by multiple users) so I haven't tried EcoAssist. This being said, I will look into it as a pre-WildlifeInsights filter to analyze the tens of thousands of images that get recorded when camera traps start to fail, or get confused with sun spots (which can be common at one of our sites, a south-facing slope with sparse canopy cover).

Thanks for sharing!

Wildlife Conservation for "Dummies"

Hello WILDLBAS community,For individuals newly venturing into the realm of Wildlife Conservation, especially Software Developers, Computer Vision researchers, or...

3 4

Maybe this is obvious, but maybe it's so obvious that you could easily forget to include this in your list of recommendations: encourage them to hang out here on WILDLABS!  I say that in all seriousness: if you get some great responses here and compile them into a list, it would be easy to forget the fact that you came to WILDLABS to get those responses.

I get questions like this frequently, and my recommended entry points are always (1) attend the WILDLABS Variety Hour series, (2) lurk on WILDLABS.net, and (3) if they express a specific interest in AI, lurk on the AI for Conservation Slack.

I usually also recommend that folks visit the Work on Climate Slack and - if they live in a major city - to attend one of the in-person Work on Climate events.  You'll see relatively little conservation talk there, but conservation tech is just a small subset of sustainability tech, and for a new person in the field, if they're interested in environmental sustainability, even if they're a bit more interested in conservation than in other aspects of sustainability, the sheer number of opportunities in non-conservation-related climate tech may help them get their hands dirty more quickly than in conservation specifically, especially if they're looking to make a full-time career transition.  But of course, I'd rather have everyone working on conservation!

Some good overview papers I'd recommend include: 

I'd also encourage you to follow the #tech4wildlife hashtags on social media! 


 

 

I'm also here for this. This is my first comment... I've been lurking for a while.

I have 20 years of professional knowledge in design, with the bulk of that being software design. I also have a keen interest in wildlife. I've never really combined the two; and I'm starting to feel like that is a waste. I have a lot to contribute. The loss of biodiversity is terrifying me. So I’m making a plan that in 2024 I’m going to combine both.

However, if I’m honest with you – I struggle with where to start. There are such vast amounts of information out there I find myself jumping all over the place. A lot of it is highly scientific, which is great – but I do not have a science background.

As suggested by the post title.. a “Wildlife Conservation for Dummies” would be exactly what I am looking for. Because in this case I’m happy to admit I am a complete dummy.
