Spy equipment used by professionals and security services like X-Mil Security can generally be broken down into several distinct groups. They are used to keep an eye on subjects during the day, as well as all night long, and typically involves video cameras, still photography, and more "analog" equipment. It is also an integral part of security guard patrol and service in the UK. Handling these type of equipment is taught as part of their training.

Video Cameras of Varying Kinds

One of the primary pieces of spy equipment currently in use is the video camera. Over the past decade or so, these specialist cameras have shrunk dramatically in size and it is now possible to mount them virtually anywhere inside or outside the home or business. By default, they can transmit live video to professionals monitoring the scene, but they come with a number of modern enhancements that extends their usefulness.

The first of these enhancements is known as FLIR, or Forward-Looking Infrared technology. This is used to show the actions of those under surveillance even during the dark of night. Infrared technology "pings" the area surrounding the camera, showing humans, animals, homes, and other scenery, as if it was mid-afternoon outside.

These cameras are also increasingly being modified in another key way: Internet connectivity. Today's surveillance cameras can be hooked up to local networks, transmitting data via the Internet and sending recorded video the cloud for a remote, DVR-like functionality. Best of all, this means cameras can be monitored from any internet-enabled computer.

Still Cameras and Mobile Applications

Whether it's a still camera or a mobile "tracking" app for smartphones, small devices are increasingly being used by the pros to learn the subject's location and make sure that they are followed, or tailed, no matter where they happen to be. Once the mobile has been tracked, it's a good idea to use digital forensics for data analysis of the phone. Great for analysing videos and images too in order to dig deeper into the investigation. Still photography has always been a key asset for professional covert surveillance, and its usefulness has only been enhanced by smaller photo sensors and better megapixel ratings in recent years.

On the flip-side, if you yourself suspect of being spied on and you have tons of sensitive information saved onto various media devices - it would be best to get a good and reliable media destruction service provider. These types of companies specialise in effectively destroying sensitive data from various types of media - such as sim cards, servers, hard drives or even video tapes.

Remote FR Transmitters

Often referred to as a "bug," remote RF transmitters are perhaps the best form of covert surveillance for monitoring in-person discussions, phone calls, and business activities. Though bug sweeping is often performed in many high-level office environments, the process is still quite rare and that makes the "bug" a very effective way to listen in on key conversations.
