Surveillance bugs vary with respect to size, type, shape and objective. They are designed for recording video, audio or even both. Installing bugs and voice recorders is usually performed by experienced detectives in smart devices, landline phones, alarms, flashlights, and sockets. The most common types are two: wired and wireless. The main difference is the capacity of storage and time recording, where the former outmatch the wireless devices. Last but not least, be aware that to install a recorder one should have physical access at your premises.
