Internal as well as external monitoring and surveillance is considered very important security measure in the CSL operation ethos. Accordingly all CSL offices are equipped with top of the line monitoring and surveillance systems.

The systems not only monitor but also record all the actions and operations for later day analysis if required. All recordings are stored with the Security Head at the site and are not accessible to any one except on explicit clearance from Head of Security at HO.

The Systems in most case are using DVR based recording and can also be viewed from remote locations.
