The success of any surveillance activity depends on how effective a person can perform observations and get information without being discovered. This usually involves concealing one’s self to avoid detection or using carefully concealed equipment such as cameras to observe at a distance. Equipment used for surveillance usually utilizes video and audio elements in order to acquire information. Though some surveillance equipment is clearly visible to the public (e.g. traffic monitoring cameras), covert operations require that equipment be hidden in plain sight to prevent the target from thinking that he or she is being observed.

One piece of equipment which has been gaining widespread popularity is the spy cam glasses. In its basic form, it is a pinhole camera mounted on an eyeglass frame. Though some people may think such equipment is the stuff of fiction, spy cam glasses are as real as any other standard surveillance equipment. Spy camera glasses range from simple designs (basic miniature camera setup) to state-of-the-art spy glasses which feature night vision and high-definition quality video output.

If you are considering acquiring spy cam glasses, the following technical information can serve as a guide.

  • Overall design. Current spy cam glasses have designs which attempt to blend in with the crowd. Some even imitate popular designs (such as Ray Bans and Wayfarers) to make it less obvious to the untrained eye. The goal is to make it as inconspicuous as possible to prevent detection.
  • The hidden camera. Its basic form includes a complete color camera featuring miniature lens, wires, and battery pack all placed inside the frame. Most spy cam glasses have multiple functions for video recording, taking snapshots, and playing mp3 files.
  • The wires. Wires used in spy cam glasses are integrated into the frame. This is to ensure that no wires are sticking out. As an alternative, wireless versions that use WiFi are also available.
  • Camera lens. It is strategically mounted on the nosepiece to give the effect that the camera “sees” in the wearer’s perspective. It features a CMOS sensor (usually about 5 megapixels) with a focal length of around 5.5mm. It is recommended to look for spy cam glasses which feature scratch-resistant polarized lenses.
  • View angle. To ensure maximum coverage, spy cam glasses offer at least 65 to 90 degrees field of view.
  • Transmitter. Spy cam glasses have the option of having a transmitter installed to allow transmission of images and sound to a secondary device such as a mobile phone. A wireless transmitter can also utilize WiFi signals for video transfers.
  • Image resolution. For most spy cam glasses the most common resolution is 400 TV screen lines.
  • Video output. Most spy cam glasses feature 960 x 720 or 1280 x 720 resolution in AVI video format at 25 to 30 fps.
  • Storage capability. The more space, the better. Having an 8GB storage chip can provide at least 4 hours worth of recording time. A growing number of devices are also exploring the idea of utilizing microSD cards for data storage.
  • Frame design. Extra care is observed when designing frames since anything that would be out of the ordinary may raise alarms and compromise an operation.
  • Battery packs. Batteries are commonly integrated into the frame design for portability. Most lithium ion batteries provide 1.5 to 2 hours of continuous video recording. Charging normally takes 2 hours.
  • Audio recording. The capability of recording audio can be turned on or off depending on the instructions received by the wearer.
  • Connectivity. Most spy cam glasses can be connected to a USB 2.0 port for fast uploading of video and audio surveillance files.

To give you an idea how far the technology has come, here are a few general specifications of some spy cam glasses in the market today:
