The files only work once they are on the card

My Trail Camera protects your trail camera with a handful of small bait files — ordinary web pages that sit quietly on the SD card and look like photos and settings. They do nothing at all until someone opens one. If your trail camera is stolen and the thief puts the card into a computer or phone and opens one of those files out of curiosity, the page reports back to you: what device opened it and from which internet connection — and its location, if the person opening it allows it in their browser.

But none of that happens while the files are still in a ZIP in your downloads folder. The protection starts the moment the files are on the SD card and the card is back in the trail camera. This guide walks you through getting them there properly.

You will need the trail camera already added to your account, the SD card, and a computer with a card reader.

Step by step

  1. Add your trail camera to your account first. When you add it, pick the correct model. For a number of brands, the "photo" bait files are then named the way that brand names its pictures — for example IMG_ for Reconyx or PICT for Browning and Bushnell. For other brands the files start with IMAG. The settings file also carries the model's name.

  2. Download the bait ZIP from your dashboard. In your list of trail cameras, click the 🪤 button next to the trail camera (Download bait files for SD card). You get a single ZIP named mtcam-trap- plus your Device ID, containing a short README.txt and a set of files that look like photos, a settings export, a detection log, a map, PIN tools and a few config files.

  3. Unzip the files on your computer. Extract the ZIP so you can see the individual files. The bait files have to be on the card as separate files — a ZIP file on the card is not what a trail camera normally saves.

  4. Copy every file onto the SD card. Put the card in your reader and copy all of the extracted files onto it. The more of them are on the card, the better your odds — a thief only has to open one of the HTML files for you to get a detection.

  5. Mix them in with real photos. If the card already has genuine photos and videos, leave them and put the bait files among them — for example into the folder where your trail camera saves its pictures (usually DCIM). A "photo" sitting among real ones looks far more natural than a lone file on an empty card.

  6. Make a folder or two. Create a folder with a name like SYSTEM or CONFIG and put a few of the files there as well. That spreads your bait across more places on the card.

  7. Safely eject the card and put it back in the trail camera. Eject the card properly so the files finish writing, then put it back into your trail camera. The trail camera keeps working as normal; the bait files just sit there until someone opens one.

Why each step matters

The whole idea rests on the files looking believable and being easy to stumble into. Brand-style file names, mixing them with real photos and adding a folder or two all serve one purpose: making a curious thief open one. You are not hacking anyone — the file only reports back when a person deliberately opens it, and location is only shared if that person allows it in their own browser. Everything else is just making the bait convincing.

It is worth testing one yourself before the trail camera goes out, so you can see a detection land in your dashboard and know the chain works end to end. We wrote a separate guide for that: Test your bait files at home — without a false theft alert. Read it before you deploy, so your own test doesn't get logged as a theft.

Common mistakes

  • Leaving the files zipped on the card. A ZIP is never opened by accident. Always extract first and copy the individual files.
  • Only copying one file. Each file you add is another chance a thief clicks it. Copy them all.
  • Editing the files. You can freely rename the HTML files to blend in, but don't open them in an editor and change what's inside — that can break the part that reports back to you.
  • Formatting the card in the trail camera afterwards. Many trail cameras erase the whole card when you format it in the camera menu. If you format, your bait files are gone — copy them on again afterwards, and check the card whenever you swap it.
  • Picking the wrong model when adding the trail camera. The file names won't match your brand and the card looks inconsistent. Set the right make and model, then download the ZIP.
  • Worrying about re-downloading. You can download the ZIP again any time — for a second card, or if you misplaced the first one. Each download contains fresh files, and the old files you already deployed keep working. Nothing you put out in the field stops reporting just because you downloaded again.

Once the card is in, you're protected

That's the entire job: download, unzip, copy everything onto the card, mix it in, eject, and redeploy. If the trail camera is ever stolen and someone opens one of the files, the detection appears in your dashboard, the trail camera is marked as stolen, and you get an email with what the file found out — evidence you can hand to the police.
