Considering all the possibilities of violent threats present at any government institution, it makes the most sense to upgrade to IP video, especially when coupled with verification and video analytics.
IP-based video surveillance systems benefit any organization that uses standard IT infrastructure due to its seamless integration, unlike analog systems that typically require a separate, proprietary, and sometimes costly network of cables. In addition, live verification of video maximizes the effectiveness of intrusion and alarm systems by providing security personnel and law enforcement a set of "digital eyes" to confirm burglaries as they are happening--or prevent them entirely.
