FIGURE 4: LiDAR technology works with millions of data
points called “point clouds” to render 3D accurate object
displays without the use of video surveillance cameras
to advance today’s security protection systems.
LiDAR sensors detect, track and classify objects;
details of a few inches can be detected at more than
100 meters. One LiDAR system in autonomous vehicles
not only detects pedestrians, but it can also tell which
direction they are facing. Figure 4 shows a detailed
LiDAR rendering with a colorization process for
added visualization.
Perimeter protection systems can accurately predict
where a thief may breach a protected space or where
a pedestrian will walk. Essentially, LiDAR’s most popular
usage is on autonomous vehicles; stationary LiDAR alerts
on traffic incidents; protection of pedestrians on cross-
walks (Figure 5) and may be used to detect and recognize
objects around a perimeter.
FIGURE 5: LiDAR is effectively used for the protection of pedestrians on crosswalks, whether in a smart city,
university or corporate campus, as well as other public venues.

Unfamiliar to many is that casinos use a form of zone
cabling architecture already. However, the individual
cabling hubs where an 802.3bt compliant power source
equipment (PSE) should be has a legacy, unsupervised
low voltage camera power supply still powering the
cameras. Collaborative security and ICT industries should
be supporting the full suite of power and management
protocols in many powered devices (PDs), such as IP
cameras and acoustic sensors.
LiDAR’s Bright Idea
Will LiDAR replace basic object recognition? The auto-
nomous vehicle industry has gifted the industry with
LiDAR devices, capable of visual object recognition that
rivals video analytics at a far lower cost.
LiDAR’s safe, projected laser units measure how long
it takes for the light to hit an object or surface, calculating
the distance to the object the light just hit and forming
data points. Millions of those data points, called “point
clouds,” are processed as a 3D visualization in seconds,
rendering accurate object displays color coded by class-
ification, height and relative position without the use
of video surveillance cameras. Objects are visualized
and recognized while maintaining privacy in public
spaces and without the high costs to redact or blur facial
features and vehicle license plates in video clips. Unlike
radar or sound waves, LiDAR does not dissipate as it
travels back to its scanner, so not only can a moving
object be recognized, but its position and direction
is also visible.
