The Intruder Alarm Report 2020

Emotion recognition – up next for surveillance?

Emotionrecognition-19In a recent surveillance tech expo held in Shenzhen, China, it seems emotion recognition in surveillance was the hot topic that resulted from the event. The technology trend looks set to be particularly prevalent in the travel sector, being rolled out at airports and subway stations.

Facial recognition has certainly become a more focused topic in the public sphere over recent years – not just in the security sector. Though, while the benefits in security and safety are numerous, concerns over private data security are never far from the surface. Blurring technology is one method that many software companies appear to be using, in order to overcome these concerns.

Other problems include the sophistication of the technology and whether it is reliable enough, as facial recognition cameras work often work best at eye level, so the camera can effectively ascertain and assess the specific distances between points of the face, in order to match this to its data.

Emotion recognition

Emotion recognition would, presumably, be taking things a step further. Some of the world’s largest companies are reportedly developing the technology, but commentators suggest it isn’t yet at a stage to be completely utilised reliably.

The idea behind emotion recognition for the security sector is likely to mean that cameras will be able to automatically recognise signs of stress and nervousness, as well as other common signs of unscrupulous activity. In western China, the technology is currently being deployed at customs, in a bid to prevent illegal acts of terrorism and smuggling, says authorities.

While it doesn’t appear quite ready for full commercial use, reports indicate it was clearly a hot topic at the expo and as examples of use continue to develop, it will certainly be interesting to see where emotion recognition technology goes.
