Outdoor Surveillance

Operational & Safety Advantages of CZM Microphone Technology

  • Captures high quality evidentiary audio data; conversations and other audio signals
  • Reduces operational costs; reduces number of surveillance staff needed and thereby labour costs
  • Improves safety for security staff
  • 24/7 unmanned, time-scheduled audio recording / surveillance
  • Configurable to a variety of environments, situations and surveillance objectives
  • Plug-n-play adaptability to video cameras, pc-based meeting recording software, content management software or digital and analogue audio recorders

CZM’s Technical Advantages

  • Greater pick-up range than directional microphones
  • Capable of audio pickup up to 250 m (273 yds) away (depending on environment, atmospheric conditions and surrounding noise levels)
  • Captures sound at 360 degrees radially
  • Captures sounds from above and below
  • One CZM microphone is equivalent to six 24-inch parabolic microphones; yet it requires less than half the space of one 24-inch parabolic mike
    • Combine the CZM microphone with a parabolic dish and it delivers the pick-up power of a hyper-parabolic microphone
  • Greater forward sound pressure gain with no increase in self-noise
  • Higher acoustic gain; virtually no distortion of audio signal
  • Easily configurable for stereo (two microphones each configured in 180 degree directional pattern)E3A Outside

CZM’s Advantages for Outdoor Applications

  • Available in camouflage colours
  • Highly portable and lightweight
  • Can be mounted horizontally or vertically
