Cellular Interception

These days, landlines are used for office-talk and faxes, not confidential conversations. A secure landline is expensive to maintain, and very difficult to successfully bug without professional training. If someone can afford to have an intelligence detail to maintain their phone lines, they do it for a reason, and they do it well. Wire-tapping is still very effective but cell phone interception is becoming increasingly wide-spread. Units designed to tap cell phone transmissions are very expensive, and usually government agencies are the only bodies legally able to use them. The GSM passive cellular interceptor is the industry standard, but they go for around $15,000. The units are capable of intercepting and recording cell signals at 900MHz and 1800/1900MHz bands, which are the most common for North American cell phones. They are also able to track and triangulate positions based on a cell signal; these devices are straight out of fiction.

Tracking

When tracking a subject is important, and so is cost-effectiveness, a GPS tracking device is the best option. There are two main types of GPS devices, those that update a receiver actively and those that are passive. A passive GPS tracking device stores positions onboard for later retrieval, the obvious downside being you must retrieve the device to find where the subject has been. An active device updates a receiver in real time so a subject can be followed. A good passive GPS device costs around $100. They are readily available and have many commercial applications: hiking, touring and flagging travel spots. An active GPS unit can cost between $500 and $1000. These are the superior choice for surveillance, because you can track a subject's movement from a remote location without the need to retrieve the transmitter.

Keylogging

Being computer-savvy is one of the most important and efficient ways of sleuthing today. One of the most reliable and simple ways to gather information from a computer is to log keystrokes. This is less intrusive and quicker than breaching that computer system's security and hacking can lead to a dangerous counter-intelligence trace. A key log can be gathered by either a physical attachment to the computer, or an invasive program that reports back to the operator. Both have their advantages, and both are priced around $100. A physical key logger is usually placed between the keyboard and computer tower where they contact, this device records every key stroke, and stores them inside its casing. These are totally undetectable digitally, as they do not interact with the computer's software. However, they can be easily seen on a close physical inspection of the computer casing. A key logging program addresses this weakness by being totally hardware-free but can be detected digitally since it uses the computers memory and must access the internet to report to the surveillance team.
