now have more options for selectively trans- mitting and storing video footage.
H.264 and H.265 compression standards were designed for consumer electronics and the film industry and took an all or nothing approach to compression. H.264 is the de-fac- to standard in video surveillance today, with H.265 being adopted over the next few years depending on products, computing power and patent circumstances which are more complex
for H.265. New security-centric compression technology, on the other hand, dynamically allocates regions of interest depending on ac- tivity in the camera’s field of view.
The part of the video frame containing interesting details are recorded in full image quality and resolution, while areas containing no forensic value are filtered out. This ensures that important details like faces, tattoos or li- cense plates are isolated and preserved, while
irrelevant areas such as white walls, lawns and vegetation are sacrificed using smoothing. The result is optimal use of available bandwidth and storage which leads to significant savings. Depending on video resolution, frame rate and scene activity it can cut bandwidth and storage requirements by half or more for most surveillance applications.
Sustainability: Becoming Better Global Citizens
This brings us to the fifth trend: sustainabil- ity which goes hand-in-hand with optimal use of resources.
Green-initiatives will continue to gain momentum. Sustainability will become a significant influence on decision-making at every level—from conserving power to mini- mizing waste. Achieving those sustainability goals will necessitate greater collaboration between customers, distributors, strategic partners, manufacturers and suppliers to en- sure better global citizenship across the en- tire value chain.
This will be expressed in a variety of ways from taking steps to lower the entire chain’s carbon footprint and assure compliance with environmental laws and regulations to ad- dressing social and ethical questions such as government corruption, human rights viola- tions, compulsory child labor, fair wages and sourcing minerals from countries where their sale would be used to finance armed conflict.
For many companies, sharing a mutual commitment to sustainability will become the litmus test for doing business together and for building long-term strategic relationships.
What Will be the Impact for You?
The megatrends mentioned in this article are certainly not exclusive to the security in- dustry. You’ll find that they have permeated many other industries as well. The questions you need to ask yourself are: How will my business deal with them? Will their impact be cataclysmic or catalytic? To know that you need to educate yourself. Attend seminars to learn what thought leaders have to say. En- gaged in conversations with industry peers. And align yourself with vendors and strate- gic partners who understand the long-term trajectory of these trends and have a solid roadmap for embracing them.
