I am about to run a whole ton of communication cable in an existing two-story house, and so I am considering buying an inspection camera to help with this. As I started looking around, they range in price from about $75 on sale to $800. I'm not a pro contractor, but this will be a tool I use a few times a year (mostly to help fishing wires), so I don't think I need anything really high-end: One model I was considering was the Royobi Tek4 Inspection Camera (which is ~$140).

enter image description here

What all the sub-$250 units seem to be missing is the ability to store images ("take pictures") on an SD card or whatever.

So my question is this: if you own an inspection camera, how often do you actually store images, and how useful is the ability? If you don't have a model that can do this, do you often wish you did (or end up using another camera to take a picture of the screen)? For casual, non-pro use, is it worthwhile to spend $100+ additional on this ability?

EDIT: Follow-up, a year and a bit later

I ended up purchasing a fairly simple model that doesn't have the ability to store pictures. I've taken a picture of the screen using another camera once or maybe twice. The problem is it's exceptionally hard to get a picture that has enough context for other people to understand. In most cases, you really have to be the one holding and manoeuvring it to understand what it is you're looking at.

I've used this primarily for fishing cables and drilling holes (using a very long installer's bit) inside finished walls, and it's allowed me to avoid hitting plumbing (in spots where I never would have even attempted to drill blind) and just generally work within tight spaces. It's very useful for getting a fish line through a hole in a sill plate while working through a hole in drywall the size of a single-gang retrofit box. I've also used it to see behind pipes and vents to trace wiring/plumbing.

It's one of those tools that you can get by without for the most part, but it saves a lot of time, and once you have it you start finding a lot of uses. That said, it's saved me enough time and from opening enough drywall that it's easily paid for itself.

  • Do any of the lower end devices have output ports? If so, you might be able to capture images/video on an external device (if you ever found the need).

  • Yeah, a few do, but it's generally a composite output. To capture, you need something like a laptop + USB tuner card and a bunch of cables connecting everything, which seems pretty awkward. I am thinking it would actually be simpler (and probably about the same quality) to just use a regular camera and take a picture of the screen. :)

  • ...but, but, how will you take pictures of problems and post them to DIY.SE without that function!? (In all seriousness though, I'd just take a picture of the screen with my phone.)

Well, I don't think you will buy such thing again in the next years, so I suggest that you consider it a major purchase and plane for all reasonable usecases, not only for laying cables. You can use it later for all sorts of inspections - finding sources of noise, finding sources of leaks, finding clogs in ducts and sewers, etc.

I believe ability to take pictures can be worth it - you can post a picture here and ask if that's mold or you can send it to the utility company to convince them that it's a leak on the common property and not on yours or you can use it to post something really curious to your twitter/facebook/whatever account. You decide whether these usecases are worth considering and how often you might encounter them.

One very important thing is you have to actually test how the thing works. It may be that it saves pictures of infernal quality that can only be used as garbage.


Unless you get a very wide field of view and a very good quality image a static picture will not tell you much anyway, so a video function would be more useful that static pictures.

However I believe you can get USB inspection cameras that are cheap and allows you to record/view on your laptop - they may be a better option for DIY.


I think the target demographic for saving pictures is pros who want to show the homeowner what they're talking about so they're not accused of making things up. When would a homeowner want to save pictures?

  • You want to take the picture in to the store / to your friend / post it here to solicit help with something
  • You find something like mold and want to document it for insurance purposes

That's the only things I can think of, and to me it's not worth the money. I've got other tools I'd rather spend the money on that would get used a lot more often.


I bought a $10 one that is simply a remote USB camera for a phone. Plugs into the micro USB charge port on my phone, or into a regular PC via a micro-> full size adapter.


  • Its very cheap - if I lost it or damaged it in a wall then I'm out $10.
  • Save function - it takes a photo on the phone like the built-in cameras.
  • Small and lightweight - sits in the toolbox in an old hard drive case for protection
  • Built in LED for illumination around the lens.


  • Colour rendition is poor - can't really tell if a wire is red or brown, or white when its up by the internal LEDs.
  • Control - as soon as the camera is out of your fingers, there is no good way to control where it looks. So you have to tape it to a wire rod, or rotate the lead in your fingers to get it looking in the right direction.
  • Illumination is poor - there's dark shadows in the "distance" and things up-close are overexposed. I've had luck shining a regular torch / flashlight through the entry hole, or through another access should one be available.

I'd 100% recommend a super cheap one for occasional use, but an expensive one would need more justification.

Here's a saved photo showing a small pebble caught in the handbrake caliper on my other half's car rear wheel. This was done by pointing camera behind wheel and using a pocket torch to light the area.
