Are you afraid that you might miss something important? With a spy camera carefully concealed on your body, you can enter a room and observe with your eyes, and then look over everything else later, with the benefit of slow motion added in. A spy camera of this sort can come in very handy, and it is easy to use and virtually undetectable.
A spy camera that is placed on your body for surveillance purposes makes use of a transmitter that sends the images it captures back to a recorder of some sort. This can be a VCR or DVD, but increasingly sophisticated technology allows it to be sent to computers. This means that you can set your computer to record the images from your camera, and then you can look over them later, focusing on different parts of the images, and seeing things that maybe you failed to see the first time with the naked eye.
There are different ways that a spy camera can be hidden on your body. Usually they look like regular objects. For instance, a camera can be hidden in a button, baseball cap, or a pair of sunglasses. They can even be in common objects that someone might carry, such as a pen, pager, cigarette pack, lighter, or book bag. Some of them are in the form of bore scopes that also serve the same purpose. In any case, the point of a spy camera is to be able to take images without others knowing what you are doing.
In addition to a spy camera hidden on your body, you might find it useful to wear a small listening device. This will only serve to augment the visuals you capture, and can even help you add context to what you are seeing. Additionally, it gives you the ability to listen again for things that you might have missed during your initial surveillance.
When you perform surveillance, it is important to make sure that all your bases are covered. This means that you should have a backup to your own eyes and ears. This is possible with a small listening device and a body worn spy camera.
