Indoor Surveillance

Operational 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

Other features of CZM microphones make them easily configurable to a variety of environments, situations and objectives.

  • Compatibility:  The CZM microphone is compatible with the majority of monitoring and recording systems
    • Plug-n-play adaptability to video cameras, pc-based meeting recording software, content management software or digital and analogue audio recorders
  • Placement & Ease of Installation:  One CZM microphone will cover virtually any corridor or office space (i.e. up to 1200 sq. ft. (40’ x 30’ room).  Mic on CeilingAdditional CZM microphones can be installed for larger areas.
    • Mounts unobtrusively on ceilings, walls, in corners, or moulded into wall panels, etc.
    • Can be mounted horizontally or vertically
    • Portable and easy set-up for off-site locations (construction equipment & materials handling yards, etc.)
  • User Friendly:  The CZM microphone technology is available as either as a stand-alone system (See E3-A Surveillance System for details), or it is easy to set-up and connect to the recording system of your choice.
  • Aesthetics:  The CZM microphone is available in a variety of colors that will match any décor; can be mounted unobtrusively on ceilings, walls, corners, or moulded into wall panels, etc.Oak CZM

CZM’s Technical Advantages

  • Delivers superior speech intelligibility for low level voice inflection (sibilance)
  • 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)

Important: It is the responsibility of the installation company and end user to install any audio listening devices and surveillance equipment in compliance with provincial/state and federal privacy laws. If you are unfamiliar with these laws, consult a qualified attorney.
