Challenge, approach and results.

Video surveillance is one of the key elements of modern technical security systems and is widely used in the public and private sectors. The findings show that the most common errors are lack of clear procedures, excessive retention of recordings and insufficient awareness amongst employees. Based on the analysis, practical recommendations have been formulated for improving compliance with legislation.

Solution and Method

Video surveillance is one of the key elements of modern technical security systems and is widely used in the public and private sectors. It is intended to ensure the safety of people, property and control over access. However, due to the possibility of identifying individuals, such systems process personal data, which means they must comply with legal regulations, particularly the General Data Protection Regulation (GDPR) and the Personal Data Protection Act (ZVOP-2).

Failure to comply with these rules can lead to serious violations of individual rights and expose the organisation to legal and, ultimately, reputational risks. The diploma thesis addresses the key legal, technical and organisational aspects of video surveillance and analyses how to ensure compliance with legislation when processing personal data. The first part of the thesis presents the basic principles of GDPR and ZVOP-2, with emphasis on lawfulness, proportionality, purpose limitation, security of processing and the rights of individuals.

Particular attention is also paid to the importance of impact assessment (DPIA) and the obligations to inform the public. The following section analyses technical aspects such as types of systems, the role of artificial intelligence and cloud services, as well as technical measures such as encryption, access control and logging. Organisational measures include employee training, internal policies, access control and risk management.

The empirical part of the thesis is based on analysis of the company's internal documents and comparable cases from practice in Slovenia and abroad.

Results

The findings show that the most common errors are lack of clear procedures, excessive retention of recordings and insufficient awareness amongst employees. Based on the analysis, practical recommendations have been formulated for improving compliance with legislation. The diploma thesis confirms that compliant and secure use of video surveillance is possible if the organisation operates thoughtfully, in a coordinated and systematic manner.

Through a comprehensive approach, the thesis emphasises the importance of cooperation between technical, legal and organisational staff. Only by connecting these areas is it possible to establish sustainable video surveillance systems that do not threaten privacy but appropriately protect it, whilst at the same time fulfilling their fundamental purpose, which is to ensure security.
