When using the SM5000 as the time server, the clock on the Endura system may become out-of-sync.

Issue

  • Clock(s) on Endura Device(s) are not synchronized.
  • Possible mismatch of video playback timestamp within WS5000/5200.
  • Personnel maintaining the system wish to follow best practices.

Product Line

Pelco Video Management

Environment

  • Pelco Endura System which includes an SM5000 or EE500.

Cause

  • Network Time Protocol Synchronization setup is invalid or not optimal.
  • There exists no Dedicated NTP Server equipment/device.

Technical Explanation

ENDURA SM5000- EXTERNAL NTP SERVER

The SM5000 System Manager is an integrated hardware and software platform that serves as the system management component of the Endura system. The SM5000 provides distributed administration of multiple devices on the network, manages system security, and functions as a key server for user and device authentication and NTP time server.

When configuring the SM5000 as the time server, please note that over a period of time, the clock on the Endura system may become out-of-sync to other clocks, such as a company clock. This is a known process called time drifting. 

The terminology normally used to describe accuracy of a clock is known as stratum level. Typical stratum levels include 0, 1, 2, or 3. The lower the value the more accurate the time. Stratum level 0 and 1 are available in specialized external NTP devices. One example is the Spectracom network time server model 9389.

Be default, the stratum level of the SM5000 is 2. Therefore, to prevent time drifting on the SM5000, it must be synchronized to a more accurate external NTP time server with a stratum level 1. The benefit of synchronizing both an Endura system and company clock to the same NTP server will ensure that time remains consistent between both systems.
