Sound Quality

The performance quality of both audio and video recording and playback has seen enormous improvement over the last few decades. Video improvements are easily noticeable and commonly incorporated through all levels. Most prominently in security with HD CCTV systems, with digital storage and playback being much more user friendly than analogue tape systems. While audio technology has gone through similar improvements, they are frequently overlooked and sometimes not applied.

Whether in an emergency or routine communication, unheard and misunderstood commands can have severe consequences and at best interfere with the efficiency of the security operation. While two-way radios are still the most common means for security officers to communicate with each other, even the most basic modern models have vastly improved transmission and speaker quality compared to what was recently the industry standard. And as with all aspects of modern communication, cell phones have completely changed the process of contacting guards or supervision and informing them of changes such as updates to post orders.
