Surveillance is often comprised of four main categories

• Video Surveillance

  • Can include the following:
    • Motion detection
    • Night vision
    • Facial recognition
  • Remote access
  • Provides real-time visual feedback
  • A wired solution security camera is physically cabled from the device back to the central monitoring station
  • A wireless solution often relies on Wi-Fi to send its signal back to the central monitoring station
  • Pan-Tilt-Zoom (PTZ) System
    • Can move the camera or its angle to better detect issues during an intrusion
  • Best places to have cameras
    • Data center
    • Telecommunications closets
    • Entrance or exit areas
  • Cameras should be configured to record what they’re observing

• Security Guards

  • Flexible and adaptable forms of surveillance that organizations use
  • Helps to reassure your staff or customers that they are safe

• Lighting

  • Proper lighting is crucial for conducting effective surveillance using both video and security guards
  • If you create well-lit areas, this can deter criminals, reduce shadows and hiding spots, and enhance the quality of your video recordings

• Sensors

  • Devices that detect and respond to external stimuli or changes in the environment

  There are four categories of sensors

  • Infrared Sensors
    • Detect changes in infrared radiation that is often emitted by warm bodies like humans or animals
  • Pressure Sensors
    • Activated whenever a specified minimum amount of weight is detected on the sensor that is embedded into the floor or a mat
  • Microwave Sensors
    • Detect movement in an area by emitting microwave pulses and measuring their reflection off of moving objects
  • Ultrasonic Sensors
    • Measures the reflection of ultrasonic waves off of moving objects
