The Department of Homeland Security (DHS) Science and Technology Directorate’s (S&T’s) National Urban Security Technology Laboratory (NUSTL) released a new Video Security Systems Technology Handbook.

Video security systems (VSS) provide surveillance capabilities used to protect people, assets, and systems. VSS equipment is often used to support comprehensive security systems by incorporating video coverage and security alarms for barriers, intrusion detection, and access control. The new handbook serves as a reference for emergency responders, law enforcement security managers, and other security specialists to aid in planning, designing, and purchasing VSS products.

This handbook was first published in July 2013 and was originally called the “CCTV Technology Handbook,” since the leading video surveillance technology at that time was closed-circuit television (CCTV). This 2025 edition has been updated to reflect current terminology and modern VSS technologies, including cameras, lenses, monitors, multiplexers, recorders, and transmission systems, and internet protocol-based systems. It includes systems that incorporate technologies like edge analytics, cloud storage and artificial intelligence. The handbook provides considerations for implementing a VSS. An overview of video analytics and programmatic considerations such as design, data storage and retention, cyber security strategies, and system integration is also included. The Video Security Systems Technology Handbook is available in NUSTL’s System Assessment and Validation for Emergency Responders (SAVER) library.
