2. INTRODUCTION
Security lighting is lighting that
intended to deter or detect
intrusions or other criminal activity
occurring on a property or site. It
can also be used to increase a
feeling of safety.
Lighting is integral to crime
prevention through environmental
design
It is usually the first line of defense
at the security fence or wall line.
3. Increased distance monitoring
Increased movement detection
Increased clarity for CCTV cameras
Deter intrusion attempts
Peace of mind
BENEFITS OF SECURITY LIGHTING
4. AREAS INCLUDED
Parking lots: five foot-
candles to two foot-
candles
Driveways four to five
foot-candles
Sidewalks four foot-
Windows and doorways:
four foot-candles
candles
5. CONTINUOUS LIGHTING
STANDBY LIGHTING
EMERGENCY LIGHTING
PORTABLE LIGHTING
Continuous lighting floods a given area with
overlapping cones of light.
Fence sensors or manual input are used
trigger lights when suspicious activity is
detected.
Powered by a battery or generator, emergency
lighting is used when normal lighting fails.
These are temporary lights that are usually
manual and movable.
TYPES OF SECURITY
LIGHTING
6. Illumination refers to the process of
providing light or brightness to an
area or object. It involves the
deliberate use of artificial light
sources to enhance visibility,
illuminate spaces, or highlight
specific objects or features.
Illumination is an essential aspect
of lighting design and plays a
significant role in various
applications, including residential,
commercial, industrial, and outdoor
settings.
ILLUMINATION
7. GENERAL OR AMBIENT LIGHTING
TASK LIGHTING
General or ambient lighting provides overall illumination to
a space, ensuring a comfortable level of brightness for
everyday activities. It is typically achieved using overhead
fixtures, such as ceiling-mounted lights, recessed lighting,
or chandeliers. General lighting aims to evenly illuminate
the entire area without creating harsh shadows.
Task lighting is focused illumination designed to facilitate
specific activities or tasks. It provides targeted light for
activities that require enhanced visibility and precision,
such as reading, writing, cooking, or working at a desk.
Task lighting sources include desk lamps, under-cabinet
lights, or adjustable spotlights. Task lighting is usually
brighter and more concentrated than general lighting to
provide ample illumination for the task at hand.
TYPES OF
ILLUMINATION
8. ACCENT LIGHTING
DECORATIVE LIGHTING
Accent lighting is used to highlight specific objects,
architectural features, or decorative elements within a
space. It adds visual interest, depth, and drama to the
environment. Accent lighting can be achieved using track
lighting, wall-mounted fixtures, or adjustable spotlights. By
directing light onto focal points, accent lighting creates
contrast and draws attention to the highlighted areas or
objects.
Decorative lighting serves aesthetic purposes, adding
beauty and visual appeal to a space. It includes decorative
fixtures, such as chandeliers, pendant lights, or wall
sconces, which are designed to be visually striking and
create a focal point. Decorative lighting fixtures often
incorporate unique shapes, materials, or intricate designs,
making them a statement piece within the overall lighting
scheme.
9. INFRA RED SECURITY LIGHTING
IR light, also known as infrared radiation, is a different type of light on the
light spectrum that emits radiant energy. It has wavelengths longer than
visible light, and it is invisible to the human eye. When it comes to security, IR
is a great option when you don’t want an intruder to know they are being
watched, but you still need surveillance capabilities to know they are there.
IR and your security cameras can provide this type of “invisible” security
since both types of cameras—digital and analog—rely on IR LEDs to be able to
“see” what’s happening when it’s dark or there isn’t an available light source.
10. When a camera switches to night mode, the images that the camera captures
inside can change from color to black and white, the picture becomes “grainy,”
and/or it becomes too dark which shows nothing but a black image. Color is
crucial to your security cameras’ ability to see clearly when the sun goes down.
By adding light, however, your camera can go back to color. This change also
increases the detail your cameras can capture, making it much easier to more
accurately see what’s going on in the cameras’ field of vision. If you want the
ability to read the license plate of an intruder, for example, you’ll need that more
detailed recording that your IR light-enhanced security cameras can provide.

Infrared illuminator
11. IR 850nm illuminators are most commonly used for day/night cameras and
closed-circuit televisions (CCTVs). They are classified as “semi-covert”
since they do produce a faint red glow that can be seen when looking at the
camera, making them not completely invisible although still very useful.
IR 940nm illuminators do not emit that faint red glow, making them nearly
invisible to the naked eye, earning them the “covert” classification. IR
940nm illuminators are widely used by law enforcement, military, traffic,
and railroads.
If you’re thinking about adding IR to your security camera, it’s important to
consider the different types. IR illuminator emits light within the following IR
range:
12. WHAT ARE INFRARED SENSORS?
Infrared sensors are a specific
type of motion sensors that use
infrared radiations. The main use-
case of this device is within
physical security and, in
particular, for intrusion detection
purposes.
The two types of infrared sensors
are active infrared sensors and
passive infrared sensors with
these last ones being the
preferred ones in the context of
physical security.
13. HOW DO INFRARED SENSORS WORK?
The functioning depends on if the sensor is active or passive (PIR).
Active infrared sensors work with radar technology and they both
emit and receive infrared radiation. This radiation hits the objects
nearby and bounces back to the receiver of the device.
Through this technology, the sensor can not only detect movement
in an environment but also how far the object is from the device.
This is especially useful in robotics to detect proximity.
14. HOW DO INFRARED SENSORS WORK?
For the physical security use case, however, passive infrared
sensors (PIR sensors) are definitely more widespread.
The PIR sensors do not emit radiation but simply receive the
one that the objects nearby are naturally emitting.
The basic functioning is that the passive infrared sensors
trigger the alarm when there is an anomaly in the infrared
waves measured in the room.
This happens if, for example, a warm object (like an intruder)
crosses ways to the signal of the device.
16. Infrared radiation works on the lower end of the electromagnetic
spectrum and is therefore invisible to the human eye. The infrared
section of the electromagnetic spectrum is found between the
visible waves and the microwaves. The infrared wavelength is
between 0.75 and 1000µm and is separated into three regions:
Near-infrared - from 0.75 to 3 3µm
Mid-infrared - from 3 to 6µm
Far-infrared - higher than 6µm
17. Infrared technology is widely used for commercial purposes for:
Night vision devices.
In astronomy, to detect objects in the universe by telescopes and
solid-state detectors.
In military activities for missile tracking.
In art restoration to analyze paintings and discover hidden painting
layers.
For tracking nanoparticles in living organisms.
