Dear Jls1900,
Firstly, I doubt whether CCTV has facility to do audio recording. CCTV just captures videos and nothing else.
Secondly, even if it is believed that CCTV can capture the audio also even then also will it tantamount to policing on the employees? What is the prime objective of running an enterprise? Is it giving value to the stakeholders, is it providing quality goods or services to its customers or keeping an eye on the employees surreptitiously? Will it not demotivate the employees? If yes, then will you be able to measure the cost of demotivation?
The unsaid part of your post is lack of trust on certain section of the employees. Why things have come to such a pass that you felt need to record the conversation of the employees? Your need shows the vitiated culture of the organisation.
Sometimes, the conversation with the customers is recorded for the training purposes. Going further, few airlines record videos also to track the customer dissatisfaction. Therefore, please specify the exact purpose of your activity. Without that it may not be possible to provide the exact solution.
Thanks,
Dinesh Divekar
