It’s too usual that it’s almost often ignored. The handy briefcase has been the equipment of choice by a wide variety of professionals ranging from teachers to salesmen to detectives and yes, even spies. The unassuming briefcase is every spy’s best friend, capable of keeping secrets, storing fascinating spy equipment and, thanks to innovations in recent years, even storing a complete surveillance system. Thinking of buying a briefcase surveillance system? Here is a short guide to its contents and how it works:
Camera
A briefcase surveillance system usually includes at least one camera integrated into its physical structure in order to record images. These cameras are capable of producing high resolution images and may be played in color or black and white.
Because this is used for surveillance purpose, the cameras are capable of handling images in low lighting. In some models, black and white cameras have the advantage of having lenses with maximum illumination of as low as .003 lux, a feature that allows it to produce good images even in near darkness.
Dependent on the model, the lenses on a briefcase camera are auto-focal lenses, although there are others that may be equipped with zoom lenses that can be manipulated remotely.
Microphone
The microphone is also included in the briefcase surveillance system so it can receive audio transmission during a video recording.
DVR
The briefcase also has a mini digital video recorder connected to the camera. All images captured by the camera are recorded by this device and may be uploaded onto a computer or viewed through a monitor later.
Power supply
Each briefcase contains cables, battery packs and power supplies. Because the briefcase surveillance system is essentially a wireless device, it derives its power from a battery pack. Batteries are generally rechargeable and capable of running the briefcase for a few hours.
How it works
The briefcase surveillance system is used basically to obtain and record information. It has been used for many years but only by professionals. Recently, though, it has been made available to private individuals.
The most usual function of this surveillance system is for recording still and video images using cameras built into the bag. The cameras are activated by a hidden switch or by way the bag is carried. One model, for example, uses its side camera if it is lifted and carried by the user. If the bag is laid on its side, it automatically switches to the camera located in its bottom panel.
