Physical intrusion detection is the process of detecting when an adversary enters or attempts to enter a space, for example for a covert house search. You can do this by making sure there is always someone in the space who would notice if an adversary tried to enter, or by monitoring the space with a video surveillance system.
A video surveillance system that monitors a space can have the following characteristics:
- The cameras can be motion-activated and send you an alert if they are detected and tampered with.
- The cameras can be positioned with the space entrances in their line of sight and/or in a discreet location.
- To prevent the system from monitoring you while you are in the space, you can turn it on just before you leave the space and turn it off as soon as you return.

| Name | Description | |
|---|---|---|
| Covert house search | You can use physical intrusion detection to detect a covert house search. | |
| Covert surveillance devices | ||
| Audio | An adversary often needs to covertly enter a space to install a covert audio surveillance device in the space. You can use physical intrusion detection to detect such a covert entry. | |
| Location | An adversary often needs to covertly enter the space where a vehicle is parked to install a covert location surveillance device on the vehicle. You can use physical intrusion detection to detect such a covert entry. | |
| Video | An adversary often needs to covertly enter a space to install a covert video surveillance device in the space. You can use physical intrusion detection to detect such a covert entry. | |
| Evidence fabrication | An adversary often needs to covertly enter a space to plant evidence in the space. You can use physical intrusion detection to detect such a covert entry. | |
| Targeted digital surveillance | ||
| Physical access | You can use physical intrusion detection to detect when a space has been physically accessed by an adversary. | |
