Risks such as these can be prevented by adopting control measures such as placing the CCTV security cameras in locked enclosures to prevent tampering and damage due to natural occurrences. Inspections can also be done to deter and identify attacks on CCTVs.
Natural disasters present a huge risk for CCTV security systems. It is virtually impossible to prevent earthquakes, floods or fires from happening; however you can minimize the damages or loss of data from your CCTV. Although insurance usually covers the loss of equipment and other valuable property, it will not be able to replace the data lost. The best solution for this is to get a good remote backup system for electronic data such as videos and images, configuration data, usage logs and more. Equipment that backs up data instantly reduce the risks of data loss in comparison to scheduled weekly/monthly/yearly backups.
Modern types of digital CCTV systems are hugely dependent on continuous computing equipment. Potential hard disk failures are usually prevented by redundant disk storage systems. The minute a disk failure has been detected, it will be substituted with a replacement disk from which data that has been lost is automatically copied. This is a very long and time-consuming process and the large storage capacity can also create additional risks. For example, the storage system may not be able to manage with rebuilding load due to missing data or maybe data from coincidental disk failures may not be protected.
Different attacks on CCTV data from human threats are grouped into the following categories:
• AVAILABILITY-this means information is not provided when needed. This is because the information may have been deleted (intentionally or otherwise) or there is a disruption to normal processes such as physical damages to the equipment and communications
• PRECISION-this means the information has been compromised. Real data may have been replaced with artificial data or the authenticity of the information presented is dubious.
• PRIVACY-information from the CCTV surveillance system has been disclosed to unauthorized people. This may have happened with or without the CCTV owner’s knowledge. A good example of this is duplicating and disseminating the video to media outlets without permission.
Mistakes and oversights can and do happen even with the best of intentions in mind. Such mistakes include unintentionally deleting records or even entire hard drives, overwriting backups, poor system maintenance, incorrect positioning of the cameras and neglecting to perform regular, scheduled backups for the security CCTV systems.
