This paper addresses video surveillance of Chilean municipalities using drones as a low-cost policing response to urban insecurity and its impact on the right to privacy and personal data protection. The text explains the municipal police powers that have been invoked to uphold the legality of video surveillance at the local level. In examining four municipal cases, it looks at how surveillance is being carried out with drones and how this has been supervised by the competent authorities, concluding that there are real risks to privacy in the operation of surveillance systems. To this end, the issue is contrasted with the applicable regulatory standards and comparative solutions. Chile lacks specific regulations for video surveillance and a robust legal framework to protect personal data. The paper also evaluates the action of courts that have legitimized surveillance, even without a legal basis, concluding that the combination of low-cost and highly intrusive technologies and the lack of an adequate legal framework creates a significant threat to the exercise of privacy and personal data protection at municipal level.
