people-counting function of their video analytics
to check exiting numbers against those
who entered the building earlier in the day.
As another backup, they can check data from
sensors installed to monitor carbon dioxide and
lighting to track how many employees remain
in each space after closing time.
In potentially hazardous workplaces such
as manufacturing or warehousing facilities, a
BMS that has been integrated with the facility's
security system can be used to create automatic
workflows that initiate lockouts, turn
on emergency lighting or open doors in case of
an emergency. These automated responses can
potentially avert life-threatening situations as
well as help reassure workers that safety systems
are working behind the scenes to protect them.
It can also help first responders know the exact
people count in a specific space or zone so that
they can take appropriate action.
Enhanced Occupant Well-Being
While HVAC and lighting systems are essential
to occupant well-being and comfort, security
systems play a role in creating and maintaining
safe, healthy buildings. When integrated with
a BMS, security and HVAC systems can work
together to enhance the performance of both.
For example, video systems and connected
sensors situated throughout a building can provide
insight into how spaces have historically
been used to predict where and when occupants
are likely to engage with one another. At
a more tactical level, they can alert staff to an
unidentified object left in the building or an
occupant who has slipped and fallen.
Foot traffic patterns, tracked by video surveillance
and analytics, can inform the BMS allowing
settings for ventilation, temperature and
humidity controls to adjust to improve occupant
comfort and well-being. Video and access
control systems can also show facility managers
where and when crowds tend to form.
In corporate office buildings, for example,
there's often a rush at building exits or turnstiles
at the end of the workday. Using a BMS,
operators can command the access control system
to temporarily open exit doors and unlock
turnstiles to ease the flow of exiting employees.
Unified Situational Awareness
The ability to monitor and control the performance
of all building systems on a single
BMS dashboard using real-time data provides

facility managers with numerous advantages.
Facility managers can, for example, track key
performance indicators for security, occupant
well-being, air quality, energy efficiency and
space utilization and fine-tune settings when
and where needed.
The BMS dashboard can also allow facility
managers to achieve integrated outcomes by
combining the functions of individual systems.
A BMS can enlist the access control system to
track how many people enter and exit a space.
Let's use the example of office building workers
who often must badge in but not out again.
Video analytics can automatically track people
exiting as well as entering a given space. More
critically, if a smoke detector alerts the BMS to
a possible fire in the building, it can signal the
access control system to lock elevators, unlock
all emergency exits and open turnstiles to expedite
safe building evacuation.
By providing big-picture visibility into occupant
well-being and safety KPIs, a BMS helps
building owners and managers use all available
assets - security systems included - to improve
occupant experience.
Foot traffic patterns, tracked
by video surveillance and
analytics, can inform a BMS to
adjust ventilation, temperature
and humidity controls.
Five key benefits:
1. Seamless security
2. Enhanced occupant
well-being
3. Unified
situational
awareness
4. Greater
productivity
5. Improved
sustainability
