b. The DVR configuration is correct
c. The system time is correct to +/- 10 seconds
d. All but one of the cameras is working i.e. 1 camera failure is allowed
without reducing the availability in the first week. For week 2 and
onward the system is considered unavailable.
Availability is defined as:-
Total Time period – Total Hours unavailable during time period
Total Time Period
Time Period is the sum of all the operational hours of buses operating
on contracts compliant with this specification during a period.
Total Hours unavailable during a time period is the sum of all the
unavailable hours of buses operating on contracts compliant with this
specification during a period
Unavailable Hours are calculated from the time the fault status is made
available to the operator to the time the system is fixed.
For a system to be considered as unavailable one or more of the
criteria in a. to d. above is not met.
The period is 28 days.
3.2 Audit
A. The operator will be audited to ensure compliance against the required
performance. The operator will be expected to maintain records of:-
i) CCTV system inspections.
ii) Faults identified and date/time fixed.
B. The operator will provide Availability reports on request.
C. LBSL shall have the right to audit against the requirements in this
specification to ensure traceability and accuracy of the data recorded.
