SOLAR STREET LIGHTS

SOLAR STREET LIGHTS


 
Solar street lighting systems are designed to operate as one integrated system. This system includes the power generation, storage and management (solar panels, battery & controller) as well as the light itself, support frame & weatherproof housing.

PIR Sensor


                                            PIR  Sensor




Passive Infrared (PIR) Occupancy Sensor is used to provide automatic lighting control for energy savings and convenience in a variety of commercial applications, including: Small offices, Conference rooms, Lounges, and Class rooms.

Electricity:
It has been estimated that a single unit of energy saved at the end use point is equal to 2.3 units of energy produced.
If energy efficient methods are mplemented properly about 25000mw equivalent capacity of power can be created through promotion of energy efficient measures.
PIR Motion Sensor for Automatic Light Control
PIR Motion Sensor is a fully automatic indoor and outdoor security / courtesy light controller capable of controlling up to 2000W incandescent or 30W x 20 fluorescent of lighting in day as well as at night. The built–in Passive Infrared (PIR) Motion Sensor turns on the connected lighting system when it detects motion in its coverage area. During the day, the built in Photocell Sensor saves electricity by deactivating the lights. You can reduce your electricity bills by using PIR Motion Sensors & Occupancy Sensors.
An adjustable time knob lets you select how long the light stays on after activation & thus stops the wastage of electricity. In the evening or at night, you can also manage at what time the lights should become ON by the LUX adjustment knob provided in the Sensor.
Energy Saving Sensor:
By the use of PIR Sensor, considerable energy can be saved by switching off the lights when the space is not in use. Savings are huge in larger facilities.
It has been estimated that a single unit of energy saved at the end use point is equal to 2.3 units of energy produced.
If energy efficient methods are implemented properly about 25000 MW equivalent capacity of power can be saved through promotion of energy efficient measures
PIR Motion Sensor for Security of Houses
If PIR Motion Sensor is installed in front yard or back yard of your house, it works as Security Sensor in nights. As if any body jumps or sneaks within its detection range, the connected lights / Sirens or beeps can be activated automatically to create Panic to the Intruder.
Working Principle: -
  • The PIR Sensor senses the motion of a human body by the change in surrounding ambient temperature when a human body passes across.
  • Then it turns on the lighting load to which it is connected.
  • The lighting load will remain ON until it senses motion.
  • Once the motion is seized it switches OFF the lighting load.
  • During the night, the LUX adjustment knob allows you to adjust the luminosity based on which the lighting load will either switch on / off automatically.
Applications: -

·    Common toilets, for lights & exhaust fans
·    Common staircase / Entrance / Basements
·    Parking areas / garden lights
·    Living room, Malls, ATMS
·    Changing rooms in shops
·    Offices / Conference Room
·    Corridors & many more!
Advantages: -
  • PIR Motion Sensors will itself recover its cost by reducing your electricity bills and will further save your electricity cost for the future.
  • Very easy installation and can be installed by in – house technician itself.
  • No separate wiring is required hence no additional installation cost.
  • No modification is required and complies with current aesthetics.
  • Pay back within ten months according to residential meter and six months according to construction meter.

DIGITAL VIDEO-AUDIO MONITORING AND BROADCASTING SYSTEM




DVAMBS

   DIGITAL VIDEO-AUDIO MONITORING AND BROADCASTING SYSTEM






   
      
    
                                                                                   





DVAMBS is specially designed for installation at schools, Hospitals, and other applications where Broadcasting and Audio-Video Monitoring is required simultaneously.

It is an essential system for the modern methods of teaching in schools and room monitoring of patients in Hospitals. Our system has been to enable the Principal/Hospital Warden to control all the class rooms or Wards
of the school building /Hospital.

DVAMBS can be used for
  • Announcement to any individual ,a group or all the stations
  • Relaying recorded lessons /speeches to rooms.
  • Contacting a particular room and getting back information.
  • Recording of conversations for enforcing discipline/patient monitoring
  • Recording of teachers lectures/attendants behavior so as to enable the teacher/attendant to overcome deficiencies.

The salient features of system DVAMBS are
  • DVAMBS is based on DIGITAL Switching Technology ,unlike electromechanically in conventional broadcast systems. this make the systems very compact, easy to manage and maintain.
  • DVAMBS has the unique feature of permitting announcement and monitoring to be made from other locations with additional Master Control Module only.

DVAMBS is capable of operating in five different modes.
  • Audio Monitor Mode: for listening the conversation at station.
  • Video monitor mode: for live video monitoring at station.
  • Address Mode: for making announcement at any particular station.
  • Group Address Mode: for making announcement to any group of stations. Any number of stations can be selected.
  • All call Mode: to address or playback recorded message to all the stations simultaneously.
