Home security involves physical security systems, alarm systems, and personal security measures to deter crime. Physical barriers like fences and lighting, as well as video surveillance, alarms, and security personnel can help secure homes and detect intrusions. Crime prevention through environmental design strategies like natural surveillance, natural access control, and natural territorial reinforcement can also help enhance security.

1. BUILDING SECURITY

2. SECURITY & BUILDING SECURITY
• Security is freedom from, or
resilience against, potential
harm (or other unwanted
coercive change) from
external forces
• Home security is both the
security hardware in place on
a property as well as personal
security practices.

3. WHY DO WE NEED SECURITY
• With the increase in Urbanization, the influx of people into cities increased
drastically and since these people are from diverse backgrounds, we see
social disorganization in society
• It provides both motive and opportunity for various crimes like burglary,
assault and battery, murder, arson, vandalism etc.,

4. WHY DO WE NEED SECURITY
• The FBI reported that in the USA,
1.7 million homes were
burglarized in 2014.
• The same report shows that an
estimated loss of $3.9 billion was
suffered by the victims in the
same year.
• Overall, when the average value
was applied to the estimated
number of burglaries, the average
dollar loss per burglary offense
was $2,251

5. HOME SECURITY
Home security mainly involves 3 things
• Security systems (doors, lockers, lighting, fences etc.,)
• Alarm systems (motion sensors, heat sensors, smoke detectors etc.,)
• Personal security measures (ensuring fenestrations are closed, alarm
systems are active etc.,)

6. PHYSICAL SECURITY
Physical security systems for homes are generally intended to:
• Deter potential intruders (e.g. warning signs and perimeter markings)
• Detect intrusions and monitor/record intruders (e.g. intruder alarms and
CCTV systems); and
• Trigger appropriate incident responses (e.g. by security guards and police)

7. PHYSICAL SECURITY
• Physical barriers such as fences,
walls, and vehicle barriers act as the
outermost layer of security
• Tall fencing, topped with barbed
wire, razor wire or metal spikes are
often emplaced on the perimeter of
a property, generally with some
type of signage that warns people
not to attempt to enter

8. CPTED
• Crime prevention through environmental design (CPTED) is a multi-
disciplinary approach to deterring criminal behaviour through
environmental design
• CPTED strategies rely upon the ability to influence offender decisions that
precede criminal acts
• It has 3 main concepts
Prevention is better than cure - Desiderius Erasmus

9. NATURAL SURVEILLANCE
The purpose of natural surveillance is to show the potential offenders of the
risk of committing a crime. It involves:
• Designing streets to increase pedestrian and bicycle traffic
• Placing windows overlooking sidewalks and parking lots
• Utilizing curved streets with multiple view points to multiple houses'
entrances

10. NATURAL SURVEILLANCE
• Not using shrubbery taller than
1 M – an aesthetically appealing
way to provide security
• Create landscape designs that
provide surveillance, especially
in proximity to designated points
of entry and opportunistic points
of entry

11. NATURAL ACCESS CONTROL
• Use a single, clearly identifiable, point of entry
• Use structures to divert people to reception areas
• Restrict entries to sensitive areas like guard rooms and control rooms
• Eliminate design features that provide access to roofs or upper levels

12. NATURALTERRITORIAL REINFORCEMENT
• Maintained premises and landscaping such that it communicates an alert
and active presence occupying the space
• Motion sensor lights at all entry points into the residence
• Provide trees in residential areas (but take care they don’t allow a means of
access to upper floors of an adjacent building)

13. Intrusion detection and electronic surveillance
CPTED methods cannot guarantee security and this is where we need the help
of technology
• Alarm systems and sensors
• Video surveillance
• Mechanical and Electronic access control systems
• Identification systems and access policies

14. ALARM SYSTEMS AND SENSORS
• Alarm systems can be installed to alert
security personnel when unauthorized
access is attempted
• Alarm systems work in tandem with
physical barriers, mechanical systems,
and security guards, serving to trigger a
response when these other forms of
security have been breached
• They consist of sensors including
motion sensors, contact sensors, and
glass break detectors

15. VIDEO SURVEILLANCE
• Surveillance cameras can be a
deterrent when placed in highly
visible locations, and are also
useful for incident verification and
historical analysis
• A human must be monitoring the
situation in real time in order to
respond in a timely manner

16. CCTVTYPES
• Dome CCTV Camera
• Bullet CCTV Camera
• C-Mount CCTV Camera
• Day/Night CCTV Camera
• Infrared/NightVision CCTV Camera
• Network/IP CCTV Camera
• Wireless CCTV Camera
• High-Definition HD CCTV Camera

17. CCTVs USED IN RESIDENTIAL AREAS
• Bullet CCTV Camera
• Day/Night CCTV Camera
• Wireless CCTV Camera
• Network/IP CCTV Camera

18. VIDEO ANALYTICS
• Although the term closed-
circuit television (CCTV) is
common, it is quickly
becoming outdated
• Video content analysis is the
capability of automatically
analysing video to detect and
determine temporal and
spatial events

19. MECHANICAL ACCESS CONTROL
• Mechanical access control systems include turnstiles, gates, doors, and
locks
• If the usage is high, Keys quickly become unmanageable, often forcing the
adoption of electronic access control

20. SECURITY PERSONNEL
• However advanced the technologies are, the security guard cannot be done
away with.There always needs to be a guard in a guard post for the people
to feel safe
• All of the technological systems that are employed to enhance physical
security are useless without a security force that is trained in their use and
maintenance, and which knows how to properly respond to breaches in
security

21. SECURITY PERSONNEL
• Security personnel perform many
functions: as patrols and at
checkpoints, to administer electronic
access control, to respond to alarms,
and to monitor and analyse video
• Though using a guard dog seems an
old way, it is proven to be an excellent
deterrence factor for potential
offenders

22. SECURITY LIGHTING
• Intruders are less likely to enter well-
lit areas for fear of being seen
• When lighting the grounds of a
facility, widely distributed low-
intensity lighting is generally
superior to small patches of high-
intensity lighting, because the latter
can have a tendency to create blind
spots for security personnel and
CCTV cameras

23. EMERGENCY LIGHTING
• An emergency light is a battery-backed lighting device that switches on
automatically when a building experiences a power outage
• They are connected to the main supply where they are charged and kick into
action when needed.They usually work up to 90 minutes

24. EXIT LIGHTS
• An exit sign is a device in a public facility denoting the location of the closest
emergency exit in case of fire or other emergency
• Most relevant codes (fire, building, health, or safety) require exit signs to be
permanently lit

25. CAR PARKING LIGHTING
Things to consider when planning lighting for parking areas
• The appropriate lighting level

26. DIMMING AND CONTROL
• The use of LED light sources and intelligent lighting controls (from PIR to
video detection systems) can be used to trigger lighting level changes, when
combined with a Smart City System
• This will provide all-important energy savings and also ensures that the
scheme is not over-lit. Helping to avoid potentially obtrusive light during
hours of darkness

27. COLOUR OF LIGHT
• Make sure pedestrians can see and be seen
• The light source with neutral white light of 4000K or warmer being
preferred

28. GLARE
• Keep column numbers to a minimum. Bracket arms and luminaires with
zero degree inclinations and choose light sources with minimal upward light
• The use of fewer columns, but higher mounting heights, may help minimise
clutter and maintenance points
