4. General considerations

   1. General considerations

A CCTV system is the combination of image capture devices, lighting, interconnections, image handling devices, etc. selected and installed to meet the customer's security surveillance requirements.

Prior to CCTV system 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 CCTV system should be designed to mitigate the assessed risks. CCTV 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 CCTV system. 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:

1. cost of loss;

1. what is the value e.g. financial, intellectual etc of the contents at the location?

2. what is the effect of disruption to activities at the location?

2. 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?

3. occupancy;

1. is the location unoccupied for extended periods?

2. are there security guards?

3. do the public have access to the location?

4. 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 previous threat?

Results from this assessment are used to help to inform decisions about what type of CCTV system to specify and install.

The results of the risk assessment (see 4.2.1) should be used to determine the requirements of the CCTV system and its components. Where appropriate a security grade should be assigned to the components, sub-systems and functions of the CCTV system. The identified security grade requirements should be specified in the OR and agreed by the customer and system designer.

Depending on the level of risk, the security grade needs to be defined for the following CCTV system functions:

1. Common interconnections

2. Storage

3. Archiving and backup

4. Alarm related information

5. System logs

6. Backup and restore of system data

7. Repetitive failure notification

8. Image handling device PSU monitoring

9. Image buffer holding time

10. Essential function device failure notification time

11. Monitoring of interconnections

12. Tamper detection

13. Authorisation code requirements

14. Time synchronisation

15. Data authentication

16. Export/copy authentication

17. Data labelling

18. Data (manipulation) protection
