When you're out of the house, you want to know that your valuables are safe from burglars and snoops. However, a full security system or even a security camera might be a little out of budget.
In some cases, you might only need to monitor a single door, say if you're renting a room or staying in a hotel. Maybe you want to watch a drawer, closet or jewelry box. In those cases, there's a simple solution that you might be able to do for free.
If you have an unused smartphone or tablet lying around, you can turn it into a security camera with very little effort. If you do use a tablet, it will need to have a rear camera.
You'll also need a stand to keep the gadget upright and pointed in the right direction. I sell a good, inexpensive smartphone and tablet stand in my store. With that in place, now you just need the app.
