With an electronic access system, every entry to your sites is logged for later review. This can be an invaluable tool when investigating vandalism or theft, or for tracking response times or techincal activities internally.
Electronic access control gives you the ability to set user-level access rights all the way down to individual doors and times. This minimizes your exposure to risk by granting no more site access than is necessary.
If a tech or outside contractor needs access to a locked site, you can open that door remotely from your central terminal.
This gives you an extra degree of flexibility while making sure that you know about entries into your sites.
Electronic access is faster and better that using locks and keys. You'll never have to look through a ring of keys to find the right one, and you won't waste space in your pocket or briefcase carrying bulky rings of keys.
