In total 290 cameras now operate throughout the district.
IronmongeryDirect, a specialist ironmongery, issued Freedom of Information requests to all local authorities in England and Wales and found that almost seven in 10 have increased their CCTV presence since 2019.
The Harrogate district's increase of 36% over the past three years ranks it above the national average of 22%.
It has experienced the 53rd largest percentage increase in cameras of the 308 councils that replied to the survey.
In Yorkshire as a whole, only York and Doncaster increased the number of CCTV cameras at a faster rate than Harrogate.
Overall the research found the number of public CCTV cameras in the UK has now risen to more than 100,000, with some local authorities more than quadrupling their surveillance over the last three years.
The authority with the highest increase in the UK was Gwynedd, in north-west Wales, where the council now operates 468 cameras – a whopping increase of 363%.
