TAPA STANDARDS – FAQ Section

CCTV Systems. FSR 5.4.2 states that a “Minimum 3 frames per second per camera” is required. Modern CCTV installations can achieve and do much better than this. Some studies suggest a minimum of 10 frames per second is needed to preserve evidential quality images. Why is the TAPA frame rate so low?

3 frames per second (FPS) is deemed by TAPA to be the minimum acceptable rate for CCTV recording. In most cases this is an acceptable speed to see the actions of someone walking across the field of vison and be able to interpret their general actions. It may, however, not be sufficient if someone is moving quickly or does something to conceal small items on their person or in a general area. The 3 FPS was set by TAPA over 10 years ago. The WWCCB has discussed this requirement and will likely propose the FPS is increased to 8 or more in the next FSR revision. The resistance to increase the FPS rate previously has come directly from some members who are concerned about the additional costs of storage and/or data bandwidth problems on their networks. While this concern had merit some years ago, the cost, image storage options and other features of modern CCTV systems now demand a review of TAPA’s minimum FPS rate requirement. One idea being discussed is to set the new frame rate for only new installations so existing facilities and re-certifications will not be penalised. More to come on this topic, we will keep you posted. There is also a useful website from IPVM that explains the quality of different FPS speeds
