Modern analog systems can be cost-effective for straightforward upgrades that reuse existing coaxial cabling. IP cameras provide greater resolution, flexible network deployment and stronger support for analytics.

Request a site survey and a retention calculation before procurement. A professional design should document camera purpose, recording duration, user access and maintenance responsibilities.
