4 General considerations
4.1 General considerations
A VSS is the combination of image capture devices, lighting, interconnections, image handling
devices, etc. selected and installed to meet the customer’s security surveillance requirements. The recommended procedure for implementing a VSS is detailed in the following subclauses 4.2 to 4.8.
4.2 Risk assessment
4.2.1 General
Prior to VSS design, and to help understand its purpose, a threat assessment and risk analysis should be performed. The threats and hazards to the premises should be identified and assessed for their likelihood and impact. These represent the risk to the premises or organization.
A risk assessment should be carried out and the VSS should be designed to mitigate the assessed risks. VSS designs should be made in accordance with this standard.
NOTE ISO 31000:2009 describes the principles for the carrying out of a risk assessment.
There is no single model design for a VSS. The design should be based on the individual location and premises, the threats and content in these locations, and the anticipated threats or damage.
Examples of issues to be considered are included below:
a) cost of loss:
1) what is the value for example financial, intellectual, etc. of the contents at the location?
2) what is the effect of disruption to activities at the location? b) location:
1) what is the quality and extent of any existing physical security?
2) is the location situated in a high crime risk area?
3) are there adverse environmental conditions?
c) occupancy:
1) is the location unoccupied for extended periods?
2) are there security guards?
3) do the public have access to the location?
d) theft, robbery and threat history:
1) is there a history of thefts, robberies or threats at the location?
2 and if so. what was the method of attack for any orevious threat?AS NZS 62676.4 pdf download.
