Thursday, December 13, 2018 -- 11:00 AM PT/2:00 PM ET

An exceeding number of police departments and law enforcement agencies, whose officers spend upwards of 3-4 hours a day completing incident reports and other time-sensitive paperwork*, are turning to smarter tools, such as speech recognition solutions, to help transform their police reporting workflows.

Join us on Thursday, December 13, 2018 at 2:00 PM ET to hear why these law enforcement professionals are embracing smarter tools to complete higher-quality reports and move mission-critical information within the CAD/RMS faster and more efficiently – all by voice.

This discussion will provide you with an understanding of:

  • What law enforcement has to say about current reporting processes
  • Why officers, especially recruits, want smarter tools to help with police paperwork
  • Why manual reporting has a negative impact on report accuracy and productivity and can hinder criminal proceedings
  • How departments can speed up data entry within the CAD/RMs and move mission-critical information more accurately and efficiently
  • How speech recognition technology can help increase officer safety and improve situational awareness and productivity on patrol
  • Why embracing smarter technology increases community visibility, and minimizes costs

Learn how your department can make incident reporting faster, safer and more complete by registering for our webinar today.

Demystifying the Convergence of LTE and LMR Networks for First Responders

Brought to you by:

View now!

Originally aired: Thursday, December 6, 2018 -- 11:00 AM PT/2:00 PM ET

Narrowband Land Mobile Radio (LMR) networks and user radio equipment have been the cornerstone of mobile communications for First Responders for decades. The trend from traditional analog to more robust wireless broadband networks in recent years has improved the overall accessibility but questions remain on whether the new networks can provide all the required capabilities First Responders need to do their job.

Increasing demand for bandwidth intensive applications such as video, advanced mapping and analytics, alongside critical voice communications has been driving adoption of broadband LTE cellular networks, such as FirstNet.

Join our panel of industry experts for this insightful 60-minute on-demand webinar as they discuss the critical differences between LMR networks and LTE networking, how these technologies can successfully co-exist, and explore the future of critical communications for First Responders.

In this session, you will learn:

  • Current and future industry trends for LTE and LMR technologies
  • Challenges and obstacles with the convergence of technologies
  • Real-life examples of successful hybrid communication strategies for First Responders
  • Recommendations for future proofing your agency; adoption of new technologies and how to bridge the gap

New Developments in Night Vision and Thermal Imaging

The difference between the original technologies used to see bad guys in the dark and today's offerings is night and day.

March 26, 2010  |  by Tim Dees - Also by this author


Most people prefer to work and live during the day, but cops know the good stuff happens after dark. Operating in that environment means that you have to be able to see to do any good, so we've been developing and buying flashlights that are bigger, brighter, smaller, lighter, and more efficient (pick any two). Flashlights have an inherent weakness in that they tell the other guy where you are, even if you can't see them.

Night vision and thermal imaging devices allow you to see the other guy without this drawback, and sometimes even allow you to see him when you wouldn't be able to do so in bright daylight.

The category of devices called "night vision" and "thermal imaging" are used in similar settings and often for similar purposes. Even so, they are distinctly different in both the way they operate and in their capabilities.

Image Intensification (I²)

The technology usually called night vision is actually a form of image intensification. Very low levels of light are amplified, or intensified, to produce an image our eyes can view.

Light energy is composed of photons, elementary physical particles that are way too small to describe. The more light there is, the more photons are present. Night vision devices use the photoelectric effect to eject electrons from a metal plate when the plate is struck by photons, then shoot the electrons at a phosphor screen, converting the electrons back into photons and making portions of the screen glow. The glow pattern is the image seen by the user.

The technology has evolved through (so far) four generations. Generation Zero or "Gen 0" focused the electrons through a funnel-like anode, accelerating them toward the cathode phosphor screen. The resulting image was highly distorted, so that you knew something was there, but might not be able to tell what it was. The concentrated stream of electrons was also hard on the phosphor screen, so the image tubes didn't last long.

Gen 1 used more efficient designs to produce electrons from photons, so the devices worked at lower light levels with slightly less image distortion. But they retained the same problems with burning out the image tubes as the Gen 0 models. Gen 1 technology produced the "starlight scopes" used by the military during the Vietnam era.

Gen 2 night vision technology incorporated a microchannel disk into the scope design, placing the disk between the photon capture plate and the cathode image tube. The microchannel disk is perforated with millions of tubes (channels), passing the electrons through without compressing the stream through the funnel of the Gen 0 and Gen 1 scopes, decreasing distortion. The electrons are multiplied thousands of times as they pass through the channels, producing a clearer image from less light.

Some night vision devices of foreign manufacture, especially those offered as military surplus, claim to use Gen 2 technology. Many of these lack the microchannel plate, so they are really Gen 1, with the inherent problems with short image tube service life.

Gen 3 is the state of the art. The microchannel disk has more and smaller holes and the electrons that pass through them are multiplied even more than before. This improves the resolution of the image, and works with even less light. Gallium-arsenide photocathode image tubes convert the electrons flowing from the microchannel plate more efficiently. The images are still monochrome (no color), but the difference is dramatic, especially with telescopic images.

Night vision devices use a standard of line-pairs-per-millimeter (lp/mm) to measure resolution of the image intensifiers. Larger numbers indicate superior resolution, or clarity of image. Some advertisements for Gen 2 night vision devices (NVDs) claim 52 lp/mm resolution, but that may be snake oil. Representatives from ITT Night Vision, one of the most advanced manufacturers of Gen 3 gear, say their best equipment renders about 51 lp/mm, and standard Gen 3 units produce about 45 lp/mm.

Older I² tubes were prone to blooms when a light source was aimed into the scope. The bloom or flash overloaded the tube, washing out all detail, required some cool-down time to recover, and sometimes destroyed the operator's accommodation to low light for several minutes. Newer technology includes overload circuits that prevent this.
