Down hole camera rig - Help me spend some money

Hi all,

This is going to be an odd request. I volunteer with a search and rescue team in California. Recently, we've had more callouts for mine-related searches and incidents.

We are a technical team that can lower people down into environments like this, but it's slow and it incurs risk. If we had another way to clear a mine shaft quickly, it would add to our capabilities and speed up searches where we suspect someone might have fallen or been dumped into an abandoned shaft.

What I'm looking to do, is build a high-quality rig that can be lowered down a hole.

Here is what I think we want:

1. Ability to record video to an on-board card/device in HD. Camera must have a wide field of view and good dynamic range.
2. The capability of sending video back (possibly at lower quality) wirelessly. I'd like suggestions for 900/1.2/2.4/5.8Ghz rigs.
3. To go along with #2, a high-quality portable monitor that also record the session to an SD card. Ideally, one that can run on 12V and that has the abiliity to use an external receiver and/or antenna that we can position directly over the shaft.
4. A bright, rugged source of diffused light. I don't care about color-correctness so much. It needs to be able to provide sufficient light for the above cameras to illuminate a 10x10' area from 10' away if at all possible.
5. The above equipment will need to be packaged so as to be waterproof. Often times mines will end in sumps, so it may do a "splashdown" at the bottom. It does not need to be dive-rated. We have machining, 3D printing and other fabrication at our disposal.
6. The whole thing should be able to be operated with a simple checklist and nto require NASA-level oeprators. It will most likely get stuffed in a Pelican case and forgotten about between missions. The batteries for everything should be easy to charge and maintain.

For purposes of this discussion, let's say the budget is $1500. More money could be begged if there is a compelling reason why it would make the project better.

Any suggestions would be most appreciated.

Cheers,

Arclight

The first thing that comes to my mind is a Go-Pro. Don't know about the wireless capabilities though, possibly with a Eye-Fi wireless SD card? Lighting could be a problem too.

How would you be lowering this? Would it be possible to just have an umbilical that would allow you to power/control a camera with Infrared capabilities and then also get the video feed back up?

Arclight,

You forgot to add how deep you want to go. We recently took delivery of the Searchcam 3000 which seems to fit all your requirements, depending on depth, and PRICE! Searchcam makes a cable probe which will go deep, but I don't think it has all the bells and whistles. You might check with your regional US&R teams to see if they have one to use. They will probably want to send a tech with it, but that can be of benefit. Looking at bodies/parts through the vid screen can be challenging if you haven't used a setup like this before and it's easy to miss important items and evidence. PM me if you have any questions, as there might be some information that is not suitable for the general public.

This would get lowered anywhere from 100' to over 700' if the shaft is straight. The raise/lower system is a separate issue, but I'm thinking about buying 200m+ reel of 3mm Spectra cord and installing it on a hand capstan system.

Keep in mind these shafts are usually pretty large (like up to 8x10' cross section). I'm not 100% sure if a sewer cam system would have sufficient light or field of view for this, but I'm open to alternatives.

Passive IR/heat detection is a good suggestion, but we're usually not looking for people who are still warm if they have taken a tumble down one of these shafts. I know it sounds morbid, but it's just the reality of the situation.

Spunky2268, check your PMs.
