Video Surveillance: what’s hot, what’s not
If you want the low down on how the latest developments in video surveillance are impacting the security sector, then look no further than The Video Surveillance Report 2019 which has just been released by IFSEC Global.
This is the fifth annual report and is based on a survey of 321 professionals involved in the supply chain for physical security systems.
Here, we bring you some of the key video surveillance highlights:
Cloud based video surveillance
This has not been as popular as you might expect, with just under one third of end users storing data on cloud-based platforms; of those that do, half use a private cloud. Cybersecurity concerns were cited as the most common reason for not using cloud-based technology.
Facial recognition technology
Facial has made a real breakthrough, with more than one in four security professionals polled now using it. Prices have come down whilst advances in processing power and deep learning algorithms have dramatically improved accuracy. The top two reasons given for adopting facial recognition is faster, easier and more effective investigations and crime prevention. However, privacy remains a major concern.
AI and deep learning
is an exciting development, albeit in its infancy. Currently only 6% of end users use video analytics driven by deep learning algorithms, but half of those who currently don’t, expect to adopt this within the next five years. The main hindrance to usage is cost, but this is expected to come down considerably.
Also, in the field of video analytics, analytics at the edge has transformed how data from video surveillance systems has been processed. Whilst the majority of people (61%) still use the traditional server based model where data is sent from cameras to a separate appliance to be analysed, analytics at the edge is growing rapidly in popularity. This form of data processing takes place within the camera and makes for more efficient use of bandwidth and storage.
With the popularity of IP based CCTV systems, cybersecurity is a key concern. Those polled thought the greatest vulnerability comes from installers neglecting this aspect during design, installation and maintenance, although end users’ lack of internal training and policies, along weaknesses in their network, were also highlighted.
Improved video images and footage are considered the overwhelming main innovations in cameras. Gone are the days of grainy images where identification of a person was nigh on impossible, thanks to improvements in image resolution, frame rates, defogging, image stabilisation, lens distortion correction and wide dynamic range.
