# What are the top-rated physical security systems for office buildings balancing strong access control against employee convenience?

&lt;p&gt;&lt;span style=&quot;background-color: transparent; color: rgb(0, 0, 0);&quot;&gt;Physical Security reviews on G2 make camera-agnostic compatibility sound simpler than the install work usually turns out to be. Camera-agnostic and hybrid-cloud claims are the easiest part of a retrofit to verify on paper and the hardest to verify in practice, since compatibility with existing hardware often depends on the specific model and firmware version of what&#39;s already installed rather than a general promise of compatibility. The install cost usually surfaces in labor and downtime rather than the software license itself, especially if any existing readers or cameras turn out to need firmware updates or replacement mounts before they&#39;ll talk to the new platform.&lt;/span&gt;&lt;/p&gt;&lt;p&gt;&lt;span style=&quot;background-color: transparent; color: rgb(0, 0, 0);&quot;&gt;A rollout that avoids ripping out hardware still requires someone to audit what&#39;s actually installed, building by building, and that audit work rarely shows up in a vendor&#39;s pitch about avoiding a full replacement. For a retrofit specifically, the software cost is usually predictable up front, while the install cost is the one that tends to surprise people once the existing hardware turns out to be less uniform than expected.&lt;/span&gt;&lt;/p&gt;&lt;p&gt;&lt;br&gt;&lt;/p&gt;&lt;p&gt;&lt;br&gt;&lt;/p&gt;
