Last week, the USCP took possession of eight Persistent Surveillance Systems Ground – Medium (PSSG-M) units, fulfilling a request that Defense Secretary Lloyd Austin approved on June 2. The units capture high-definition video and include night vision, but do not feature facial recognition capabilities.

"This technology will be integrated with existing USCP camera infrastructure, providing greater high definition surveillance capacity to meet steady-state mission requirements and help identify emerging threats," the Pentagon said.

The same technology was used by troops during the wars in Iraq and Afghanistan to observe large areas day and night.

The Army will install the units and train Capitol Police on how to operate the systems, the Pentagon said.

In a statement last week, the USCP called the technology "state-of-the-art campus surveillance technology, which will enhance the ability to detect and monitor threat activity."
