Another boom year for HD CCTV
Trend3:
More storage options for video surveillance
Storage configured for video surveillance is gaining
more industry attention. The RAw capacity shipped
of SAN, NAS and dAS storage used for video surveil-
lance is increasing at around 40% each year. (CAGR
2014-19). The traditional boxed appliance model,
(born out of the death of the VCR) typically included
DVRs in a capacity to suit and perhaps external DAS
for extra capacity; this was simple and it worked. Yet
video surveillance has evolved and this type of ap-
proach has been insufficient for an increasing percen-
tage of users.
Average camera resolution continues to increase. HD-compliant 1080p
25/30 fps cameras have established themselves as the minimum expected
from new cameras. Panoramic and 4K cameras are two further storage-
hungry high-growth categories.
Analytics and more efficient compression technologies will reduce
some of the storage requirements. However, these technologies are not
going to offset the large increase of data from increasing shipments of
higher specification cameras, which are capturing much more informa-
tion than ever before.
Also the increasing perceived value of video information will increase
the length of time it is stored. Increased storage requirements in video
surveillance is the consequence that few want to talk about or to plan for.
Body-worn camera boom
The body-worn camera market could drive the wider video surveil-
lance industry to re-assess its approach to storage design. Shipments of
body-worn cameras are forecast to boom in 2016. Specifically, in the
United States, tens of thousands of new body-worn cameras will enter
the market with the assistance of new federal funding. All these cameras
require their footage to be retained for long periods (often years). Despite
the unit shipments of body-worn cameras being only a drop in the ocean
compared with those of traditional fixed video surveillance cameras,
several parallels can be drawn between the storage headaches faced by
both markets:
· Many of the end-users and those tasked with maintaining body-
worn cameras (law enforcement officers) have a limited IT background
(like many security professionals). They need an integrated system de-
signed with total cost of ownership in mind, accounting for both upfront
and maintenance costs.
· The probability of reviewing footage decreases with its age. How-
ever, preferably it should remain accessible. Increasing retention can
provide anti- litigation, insurance and operational assistance. An efficient
storage infrastructure can enable the use of post-recording analytics.
· There's likely to be an advantage in pulling together stored informa-
tion from different inputs video + metadata from other sensors:
- Body-worn for law enforcement other digital evidence or wearable
tech.
- Video surveillance connected IoT devices.
Initial cloud storage offerings have made headway in the body-worn
camera market, yet IHS believes that the longer-term costs of increased
spec. cameras and more widespread deployment mean a hybrid approach
will best suit the larger systems. This approach will incorporate multiple
storage types and will often be the most cost-efficient solution. In its
most basic form, this means a combination of cloud and local storage
with one unified platform.
Increased use of multiple tiers of storage
The use of this approach for body-worn camera storage could be the
catalyst for the wider adoption of a similar approach in video surveillance
storage, especially in higher channel-count systems.
In the market for storage used for video surveillance in 2016 we can
expect to see: Increased use of multiple tiers of storage.
Use of storage tiers in video surveillance has previously meant just a sepa-
rate archive or directly attaching add-on capacity to recorder appliances.
Now we're seeing a multitude of options designed for video surveillance,
which all pull together different storage tiers (in some cases storage me-
dia) into a unified platform. This allows more efficiency in varying how
recorded footage is treated throughout its lifetime; in some cases data is
moved from edge to centralised storage and into the cloud.
Video surveillance suppliers and storage specialists
As storage demands have increased, some video vendors are turning
to specialists to provide systems which can cope with high numbers of
high-resolution video streams. In terms of video management software,
this means the integration of data from different storage types, tiers and
physical locations is required, with similar performance from each.
Chinese vendors increase enterprise storage offerings
Commonly storage can account for most of the equipment cost for
higher-channel-count systems. Large capacity storage can be very expen-
sive. As seen in many product categories, Chinese vendors have extremely
competitive offerings; specific storage for video surveillance has been
behind cameras on their product development roadmap. This year we'll
see more enterprise storage products for video surveillance available from
Chinese vendors.
The industry has moved so far from the days of the cassette recorder.
However, its implementation of enterprise storage may be forced to
evolve further to cope with the demands of increasingly low priced but
high specification cameras.

video surveillance trends
Top video surveillance
trends for 2016
than HD SDI solutions and a greater cable reach.
Most of the growth in demand for HD CCTV since 2012 has
therefore come from the three leading "analogue HD" formats with each
battling to become the dominant standard. The incompatibility of these
standards has been cited as a major drawback to their even greater adop-
tion. It is argued that once a user has selected cameras and recorders using
one of these technologies, they are tied in to replacing them and expan-
ding their system with cameras and recorders using the same technology.
In late October 2015, at the CPSE Chinese security trade show, the chip
vendor Techpoint announced that it had made the first step in removing
this barrier. It claimed that DVRs using the latest generation of its TVI
chips can record footage from both TVI cameras and AHD cameras.
Another barrier to greater adoption of HD CCTV that is often cited
is that its maximum image resolution is much lower than that of network
cameras. Techpoint announced plans to overcome this barrier too, by
launching 3 megapixel equivalent cameras, followed by 5 and 8 mega-
pixel equivalents. Its competitors are likely to respond by improving the
functionality of their own solutions.
Given this background, IHS forecasts that HD CCTV equipment will
be increasingly selected in preference to SD analogue equipment. Growth
in the longer term is likely to be constrained by the move to IP cameras.
However, 2016 at least will be another boom year for HD CCTV.
