Digital Videos Vulnerability to Data Tampering Necessitates Authenticity Certifications
The compelling benefits of digital video recording such as excess storage, easy retrieval of
footage, and remote viewing have helped it outstrip analog recording in video surveillance. The
clarity of digital video and its superior data processing have further cemented its dominance over
analog video. Data on digital format is even admissible as evidence in courts of law. However, it is
still grappling with certain technical shortcomings, one of which is that it is not completely
tamper-proof. As technologies such as artificial intelligence (AI) are still nascent, very little
has been done to standardize AI-related technology. To ensure that the information recorded is
authentic, the industry for data processing technologies used in video surveillance has to establish
certification or trademark standards.
This Technical Insights study provides an overview of advances in recording and data processing
technologies for video surveillance. It covers technologies such as closed circuit television (CCTV),
digital video recorder (DVR), network video recorder (NVR), automatic network replenishment (ANR),
and video cassette recorders (VCR). The research service enables companies to align their
positioning strategies to benefit from these emerging technologies.
Easy Availability of Broadband Technology Encourages Use of Digital Format
The availability of broadband technology is actively promoting the uptake of Internet Protocol
(IP)-based video surveillance. Since the use of broadband technology is rapidly becoming prevalent
globally, end users are becoming more enthusiastic about using network-based security systems that
provide secure coverage of large areas. Higher bandwidth, along with better compression techniques,
is greatly helping the provision of sophisticated solutions on IP platforms.
"The availability of broadband Internet also fuelled the use of DVRs and NVRs, which has
allowed greater amounts of data to be stored," says the analyst of this research service.
"It also enables the capture of better quality pictures than CCTV."
Video Surveillances Strong Value Proposition Attracts Varied Markets
Video surveillance technologys brisk development is expected to have a profound impact on
several other technologies including digital signal processors (DSPs), imaging software, and mass
storage. Such massive-scale developments are anticipated to influence several end-user sectors to
deploy the technology. The most proactive adopter is homeland security, as is evidenced by the
considerable investments made by users at both corporate and national levels on CCTV infrastructure
and video IP solutions. "This increased need for security, while being a crucial market driver,
is also a technology driver since it encourages the security software market to invent more reliable
and fail-proof systems," notes the analyst.
Although national security is expected to be the prime driver of video surveillance, corporations
also have a robust business case for migrating to digital video. Video surveillance solutions are
likely to be implemented in sectors such as healthcare, mining, gambling, and critical
infrastructure areas in future.
