DYNAMIC SURVEILLANCE STREET LIGHT
BACKGROUND
Field
[0001] Embodiments of the present disclosure relate to dynamic surveillance street light.
In particular, embodiments of the present disclosure relate to a street light having an
embedded camera that can be operated intelligently depending on signal generated by
lighting system.
Description of the Related Art
[0002] Background description includes information that may be useful in understanding
the present invention. It is not an admission that any of the information provided herein is
prior art or relevant to the presently claimed invention, or that any publication specifically or
implicitly referenced is prior art.
[0003] Conventionally, street lights works as guiding lights in darkness and lighten and
secure a public facilities by providing light to the pedestrians and other on road vehicles.
They also help in preventing any crime or unlawful activity from happening in areas
illuminated by them. With development of technology and science the ways of configuring a
street light and various usages associated with it changed. In place of old sodium vapour
lights, or incandescent light bulbs, we started installing mercury light tubes, CFL lights, etc.
to reduce energy consumption for same illuminating power. Now LED lights are available in
markets that reduce the consumption of electric energy much more. We have started
installing solar powered panels for harnessing solar energy for generating electricity to light
up the street lamp. Street lights provide a feel of safety to people in their vicinity. Also, video
surveillance systems are being installed at different places to enhance security. These
surveillance cameras are installed at different places and are controlled through locally or
through a remote device.
[0004] It has been observed that most of the time the street lights or camera keeps
working even if no one is there and hence lots of resources are used without solving any
purpose. It has also been observed that installation of the street lighting system and
surveillance camera independently is not very cost effective. Some cameras can record videos
only in presence of light and hence there is dependency on light for these cameras to work
properly.
[0005] To overcome some of the above defined problems or inefficient issues, modern
lighting systems are coming with presence sensors integrated with them, that allow lights to
be controlled based on the presence/ absence of a object of interest, for example a moving
3
object. However, not many of these lighting systems have any control over the surveillance
camera, which keeps recording dark (blank) image in absence of light, and hence resources
consumed by surveillance cameras don’t solve any purpose. In other circumstances, it’s
possible that the camera observes some moving object even in dark when lights are switched
off, and to get a clear image, it may require that the lights are switched on. As the video
surveillance system and lighting system are not integrated to work in conjunction with each
other, sometime the lights remain switched off even when camera system requires it to be
turned ON, or camera system keeps on recording the blank image, even if there is no one and
when the lights are switched OFF.
[0006] Therefore there is required a system and method that allow integration of presence
based lighting system and dynamical video surveillance. Systems and methods are required to
optimize consumption of resources, such as power, storage, communication bandwidth etc.

SUMMARY
[0015] Embodiments of the present disclosure relate to a dynamic surveillance street light
(DSSL) and system forintelligently controlling a smart light and a surveillance camera. An
embodiment of the present disclosure provides dynamic surveillance street light that includes
a smart light and a surveillance camera, wherein the smart light can be controlled through a
current regulator circuit, using pulse width modulation (PWM) adjustment technique, that
controls dimming or illumination of the smart light based on input from a presence sensor
and wherein the surveillance camera can initiate or stop recording based on the input from the
presence sensor. In an exemplary embodiment, a Light dependent resistor (LDR) can
5
alternatively be used for controlling the dimming and illumination of the smart light, and
initiating or stopping the recording by the surveillance camera.
[0016] In an exemplary implementation, the smart light starts illuminating with full
intensity and the surveillance camera starts recording when presence of an external or moving
object is detected by the presence sensor. The smart light can start dimming and recording
through the surveillance camera can be stopped when the presence sensor does not detect any
external object or moving object for a duration of time.
[0017] In an exemplary embodiment, the DSSL can alternatively be configured to
mutually integrate the smart light and surveillance camera in such as way, that the dimming
and brightness of the smart light can be controlled based on movement of an object detected
by analysis of video captured by the surveillance camera, so as to enable the smart light to
illuminate with full intensity if a movement of an object is detected and dim the smart light if
there is no movement of object detected.
[0018] In an embodiment, the surveillance camera of DSSL can be an IP enabled
surveillance camera, which can be configured to transmit the recorded video through a wired
communication channel. In another embodiment, the surveillance camera can be configured
to transmit the recorded video through a wireless communication channel. In yet another
embodiment, the surveillance camera may have an internal storage to store the captured video
which can be transferred to a display through an external interface such as USB, or HDMI
port.
[0019] In an exemplary implementation, the surveillance camera integrated with the
smart light can be configured to be controlled from a remote surveillance room through a
wired or wireless means. The recording through the surveillance camera can be initiated or
stopped from a remote location. In an exemplary implementation, recorded data can be stored
at a remote database using a wireless or wired communication channel.
[0020] In an aspect, the DSSL also referred interchangeably as smart light with
surveillance camera, enables a traditional street light to become smart light by embedding a
presence sensor and a surveillance camera with it.The data storage means for storing recorded
data using digital video recording (DVR), etc., can be an internal storage that can be placed
inside the camera embedded with the street light or can be an external storage (storage can be
external hard drives, server based storage, etc.) means present at the dynamic surveillance
resource room.
[0021] In an exemplary implementation, the smart light can use LEDs, illumination or
dimming of which can be automatically controlled using Light dependent resistor (LDR).
6
[0022] In an exemplary aspect, the DSSL can detect an individual (or group of people)
performing any kind of suspicious activities and figure out if safety of an individual or object
has been compromised, if a person has met with an accident, or faces an emergency/crisis etc.
within the range of its illumination. On detection of any such activity the DSSL can raise an
alert and start recording high resolution videos. The video or image captured via the
surveillance camera can be communicated to the dynamic surveillance resource room over a
suitable wired channel (such as LAN, WAN, etc.), wireless communication channel (such as
Bluetooth, Zigbee, infrared, NFC, or an IP network, etc.) or using existing power
transmission network.
[0023] An embodiment of the present disclosure provides a system of smart light and
surveillance camera for intelligently controlling a smart light and a surveillance camera. The
system for intelligently controlling a smart light and a surveillance camera includes a control
signal triggering module configured to trigger a control signal indicative of presence of a
moving object, for controlling a smart light and a surveillance camera based on one or
combination of detection of presence of a moving object by a presence sensor and detection
of light of predefined intensity on a light dependent resistor, a smart light control module
configured to control illumination or dimming of smart light based on the control signal, a
surveillance camera control module configured to initiate or stop recording of video through
the surveillance camera and a communication module configured to transfer recorded video
through a wired or wireless communication channel to a remote database and enable
controlling of surveillance camera through a remote surveillance room. In an embodiment,
the communication module can be configured to user any or combination of a suitable wired
(such as LAN, WAN, etc.), wireless communication channel (such as Bluetooth, Zigbee,
infrared, NFC, or an IP network, etc.) or can use existing power transmission network for
communication purpose.
[0024] In an exemplary embodiment, the system on detecting presence of a moving
object can illuminate light to make the object more clearly visible , so that camera can
capture more clear images and videos of the object and it’s activities. The system can further
include a lighting control module, configured to, intelligently control the diming and
illumination/brightness of the (LED) lights depending on the presence of any object in the
vicinity of the light and provide a clear view for the camera to record the activity with more
clarity.
[0025] In an exemplary embodiment, the surveillance camera control module can be
configured to control the functionality and settings for panning and rotating of the camera.
The camera control module on receiving a control command indicative of presence of a
7
moving object can wake-up the surveillance camera from sleep mode and cause it to start
recording. The camera control module can enable the surveillance camera to go in sleep
mode and cause it to stop recording if it does not receive any control command indicative of
presence of a moving object from the triggering module.
[0026] In an aspect, the DSSL or system of present disclosure can achieve 24x7
surveillance providing security by means of surveillance and simultaneously save on energy
consumption.

light (DSSL). In an exemplary implementation, the DSSL can have an integrated presence
sensor that can trigger a control signal for illuminating the smart light and start recording
video through the IP enabled surveillance camera, based on presence of a moving object in
field of view of camera or area of illumination of smart light. In an exemplary

[0060] In an exemplary implementation, the DSSL, for example smart light 102a
integrated with IP enabled surveillance camera 104a, can transfer the recorded video through
a wired or wireless communication channel to a surveillance room 108 through a network
106. The network 106 can be a LAN, WAN, MAN or internet. In an exemplary
implementation, the recorded video can be transferred from the DSSL to the surveillance
room 108 through a suitably configured power line transmission network. In an exemplary
implementation, features and control setting of the IP enabled camera can be controlled from
the surveillance room.
[0061] FIG. 2 illustrates exemplary functional modules of a system 200 for intelligently
controlling an integrated light and a surveillance camera in accordance with an embodiment
of the present disclosure. A system for controlling an integrated light and surveillance camera
includes a control command triggering module 202 configured to trigger a control signal
14
based on detection of a moving object by means of a sensor, a light control module 204
configured to control illumination and dimming of the smart light based on the control signal,
and a surveillance camera control module 206 configured to initiate or stop recording of
video through the surveillance camera based on the control signal. In an exemplary
implementation, the sensor can be light dependent resistor or a presence detection sensor. In
an exemplary implementation, the surveillance camera can be configured with a local storage
device to store the video.
[0062] In an exemplary implementation, the light control module 204 can be configured
to illuminate the light to a first defined intensity level upon receiving the control signal, and
dim the light to a second defined intensity level when the control signal is not received for a
first predefined time interval.
[0063] In an exemplary implementation, the surveillance camera control module 206 can
be configured to initiate recording of the video upon receiving the control signal and stop the
recording of the video when the control signal is not received for a predefined time interval.
[0064] The system can further include a communication module 208 configured to
transfer the video through a wired or wireless communication channel to a remote
surveillance room. The communication module 208 can be configured to use any or
combination of a suitable wired (such as LAN, WAN, etc.), wireless communication channel
(such as Bluetooth, Zigbee, infrared, NFC, or an IP network, etc.) or can use existing power
transmission network for such communication.
[0065] In an exemplary embodiment, the system 200 on detecting presence of an moving
object can increase it’s light intensity to make the object more clearly visible , so that camera
can capture more clear images and videos of the object and it’s activities. The system can
further include a lighting control module, configured to, intelligently control the brightness
of the (LED) lights depending on the presence of any object in the vicinity of the light and
provide a clear view for the camera to record the activity with more clarity and detail.
[0066] In an exemplary embodiment, the module 206 can be configured to control the
functionality and settings for panning and rotating of the camera. The surveillance camera
control module 206 on receiving a control command indicative of presence of a moving
object can wake-up the surveillance camera from sleep mode and cause it to start recording.
The camera control module can enable the surveillance camera to go in sleep mode and cause
it to stop recording if it does not receive any control command indicative of presence of a
moving object from the triggering module.
[0067] In an exemplary implementation, the module 206 can be further configured to
initiate the recording of video on receipt of a recording command from a recording command
15
generator configured with a light dependent resister to generate the recording command when
light of predefined intensity is received on the light dependent resister.
[0068] FIG. 3 illustrates an exemplary network setting that allows a smart light with
surveillance camera to choose any available access point to communicate with a surveillance
room in accordance with an embodiment of the present disclosure. As shown in FIG. 3, a
smart light with surveillance camera 304 can select any available access point, for example
access point 302b, from list of available access point 302a-n to transfer the recoded video to a
surveillance room 308 through network 306. In an exemplary implementation, the smart light
with surveillance camera 304 can user the access point for which signal strength is highest
and which has the highest bandwidth available. In an exemplary implementation, the access
point can be a wireless access point or a wireless router, a wireless gateway or a mobile
cellular tower or a wired network device. A smart light with surveillance camera 302 can
also be referred as dynamic surveillance street light, as smart light and surveillance camera is
dynamically activated based on detection of presence of a moving object.
[0069] In an exemplary implementation, the surveillance camera of DSSL in general can
be configured to record low resolution video and can start recording high resolution video
once a moving object is detected by the DSSL.
[0070] FIG. 4 illustrates an exemplary DSSL having smart lights, integrated presence
sensor and surveillance camera in accordance with an embodiment of the present disclosure.
As shown in FIG. 4, the DSSL 400 can include a smart light 402, made of LEDs, a presence
sensor 404 and a surveillance camera 406. The surveillance camera 406 can start recording
once the smart light 402 is illuminated. As soon as the smart light 402 starts dimming, as
result of absence of any movement in field of view or area of illumination, the surveillance
camera 406 can go in sleep mode. In sleep mode the surveillance camera can stop recoding
video and hence save lots of resources. In an exemplary implementation, the surveillance
camera 406 can be configured to record low resolution video during sleep mode. In an
exemplary implementation, video captured during sleep mode can be analyzed and if any
presence of suspicious activity is detected, a control signal can be generated to switch on the
smart light 402 with full illumination and surveillance camera 406 can start recording the
video in high definition mode.
[0071] In an exemplary implementation, the smart light 402 can be controlled through a
current regulator circuit, using pulse width modulation (PWM) adjustment technique, that
control dimming or illumination of the smart light based on input from a presence sensor 404.
[0072] Controlling of smart light 402 and surveillance camera 406 by auto sensing can
save lots of energy, storage and communication resources as well extend life of smart light

402. The DSSL 400 can be configured to compress the recorded video and stream the
recorded video to a surveillance room or over a computing device, such as laptop, tablet or
mobile phone, of a user. The DSSL 400 can enable a user to get real time high definition
video from surveillance camera 406 via internet, intranet available with a web browser or a
streaming media player DVD (digital video platform). An authorized user can also remotely
control and configure parameters of surveillance camera.
[0073] As one may appreciate, smart light 402 having embedded surveillance camera 406
can be used for dynamic lighting and surveillance in office blocks, shopping centers, hostels,
schools, underground garages, malls, public places etc. In an exemplary embodiment, the
DSSL 400 may have an internal local storage to store recorded videos.
