Traditional Video Surveillance ($50,000+)
vs.
Event-Based Videofied Solution ($2,500)
Executive Summary:
Totally Wireless Video Security has been effective but cost and complexity has limited
deployment to protecting high value assets. Separating the “surveillance” component
from the “security” component has reduced the cost by orders of magnitude and made
portable Video Security affordable for mass deployment to small groups and individual
personnel. The Videofied (video+verified) solution eliminates continuous recording and
provides “event-based video” of only the events triggered by motion sensors. When the
sensors detect an intruder, a 10 second video clip is captured and sent to the command
post or monitoring station along with the alert. This video enables appropriate response
for specific events.
The Videofied system has no A/C connection and is entirely self-powered – no wires
anywhere. Videofied cameras are equipped with infrared illuminators for night vision
and integrated with a motion sensor and encrypted transceiver in a package the size of a
fist. The cameras use 915 MHz spread spectrum RF to communicate to a book-size

communicator which transmits alarm events and video to the command post over the cell
network. The RF range between the cameras and communicator is 2,000 feet line of
sight. A single communicator can manage up to 24 cameras spread out over half a square
mile or an entire building.
Videofied enhances existing surveillance systems by providing early warning for more
sophisticated pan/tilt/zoom cameras. Wireless camera placement makes it possible to see
around corners, inside buildings and cover areas normally hidden from traditional mastmounted cameras. The system is available in a fly-away kit the size of a briefcase. This
low cost, totally wireless video security can be deployed with small mobile teams that
were impossible to protect using more expensive video surveillance systems. Eventbased video enhances force protection because it is affordable enough to provide even
individual personnel with video protection. It is portable, self-powered, and fits in a
briefcase; powerful video security in a small deployable package.

TOTALLY WIRELESS SURVEILLANCE: Sophisticated and Powerful
Totally wireless video systems have been available for decades but, because they cost
hundreds of thousands of dollars, they were used in only in extreme situations or military
applications. This is changing with the growth in wireless communications technology
and the cost of such systems has been reduced in recent years. Digital networks and
wireless communications allow wireless cameras where wired cameras had been too
difficult or expensive to install. Integrators create a self contained totally wireless video
system by adding power using a generator or solar panel, on a platform or a trailer
mounted portable “kit” more like television news vans than intrusion alarms. In fact,
these totally wireless systems are powerful security tools that can be very effective and
are certainly growing in popularity as their cost comes down.
The entire wireless system is designed around a platform or trailer with a vertical “mast”
for mounting cameras, radio antennas and communications electronics. The integrator
builds each system for specific project requirements based upon:
 Radio Frequency
Radio communications for these systems usually are based on one of 4 bands from
900 MHz to 5.8 GHz. The ideal frequency is a compromise based on a number of
factors including the amount of data to be transmitted, site conditions, obstructions in
line-of-sight, available power and compatibility with other equipment.
 Power Consumption
The totally wireless kit must include a generator, fuel cell or solar panels and
batteries. Power consumption of the entire system, length of desired operation,
environmental conditions are some of the main considerations.
 Cameras
Often multiple cameras are needed to meet requirements incorporating features such
as night vision, field of view, zoom and resistance to environmental extremes.
 Video Analytics
Analytics are becoming increasingly important in sophisticated systems. Analytics
are a way of programming computers or the cameras themselves to be able to
intelligently “alert” someone to an event or intelligently target the camera itself on an
object. Analytics eliminate a person staring for hours at a video display(s) waiting
for something to happen.
 Other Sensors
Additional sensors are often used to monitor a site such as infrared beams, pressure
switches, infrared motion detectors, etc.
 A receiving station with staff specially trained in video surveillance must monitor the
site.
Depending on the options chosen, systems are available with infrared cameras that can
spot an intruder hidden in the bushes at 200 yards or read a license plate at half a mile.
While these systems used to cost hundreds of thousands of dollars, now a typical solution
of this type starts at around $50,000. Still the cost and complexity of such systems makes
mass marketing difficult or impossible and many price sensitive applications requiring

totally wireless video are unserved. In addition, cameras still do not look around corners
or through buildings which makes “total coverage” of some sites difficult.
EVENT-BASED VIDEOFIED: Affordable, Portable, Anywhere
Commercial intrusion alarm technology evolved from wired systems to wireless in the
1980s with the appearance of a new generation of cost-effective wireless sensors from
several suppliers. Next, transmitting alarms from the security panel to the monitoring
station went wireless using proprietary narrow band radio, analog cell phone and finally
the inexpensive digital GPRS cell network. Yet the typical wireless intrusion alarm is
still connected to A/C power and doesn’t work in many totally wireless applications.
Video has been “surveillance-centric” by providing remote real time viewing from
continuously recording cameras. Commercial manufactures created video security
systems by integrating video with intrusion alarm panels and other sensors. These
systems are not wireless and run on A/C power. Videofied separated “surveillance” from
a video intrusion alarm to create a new cost-effective wireless video solution. The
product won “Best in Show” award for new product innovation by the Security Industry
Association at the ISC West in Las Vegas 2007. The system is optimized for video
security instead of surveillance – the camera is only on during an alarm. Videofied is
self-powered and transmits alarm events and the video of what caused them over the
standard GPRS cell network. The innovation is not so much what the system does but
the price at which it does it – a technology inflection point. Videofied made video
security portable and affordable. Videofied dramatically reduced equipment costs while
eliminating most of the complexity/cost of integration/installation. The cost-effective
concept is designed around the wireless P-Cam, a digital camera integrated with passive
infrared (PIR) motion sensor complete with an internal battery-pack. The motion sensor
acts as a reliable analytic (with much greater accuracy than camera-based pixel change
systems) for the digital camera – the camera only sends videos of what caused the alarm.
The P-Cam also includes infrared illuminators for true night vision.
In ideal conditions the batteries on the panel and P-Cams will last 4 years and eliminate
the need for generators or solar panels. The P-Cam conserves power by keeping the
camera off until an intruder trips the motion sensor. When an intruder is detected, the
camera takes a 10 second video and compresses the video to a small 200K MPEG file.
This file is encrypted and sent by radio transceiver to the security panel which is powered
by 2 sets of batteries (one used as a backup). The range between the camera and panel is
up to 2,000 feet line of sight. The control panel sends the alarm and video to the
monitoring station over the GPRS cell network – the operator sees the alarm and the
video of what caused it. During the alarm, the monitoring operator can request real-time
images from the P-Cams – but this is much different from surveillance where cameras are
always filming/recording and accessible for remote viewing. Videofied can manage up
to 24 P-Cams. The current camera is not intended to get wet and operates down to 32 F.
The new IP 65 weatherproof rated P-Cam will operate down to -20 F, ideal for securing
site perimeters and outdoor assets.

The basic “kit” in this case includes two cameras, the control panel, and keypad has a
retail price of less than $2,500 while a system with 10+ cameras and the optional add-ons
is well under $10,000. Monitoring Videofied is substantially less expensive than video
surveillance because it is so simple it doesn’t require special operators or workstations.
Monitoring personnel don’t need to manage surveillance controls for pan, tilt, and zoom
and remote DVR operation.
Applications:
This affordable new concept solves historically difficult security applications where
power and communications don’t exist or are cost prohibitive. Many situations often
required portable or temporary security installations where wires were impractical or
impossible.
 Force Protection applications requiring intrusion detection to secure a perimeter or
building now have an affordable solution, even if the location changes daily.
Videofied is affordable enough to protect small groups or even individual personnel.
 Storage Trailers and shipping containers are vulnerable with no power or
communications. Totally wireless video using the GPRS cell network can provide
video security even in transit. It is perfect for high-value shipments. Additionally, it
is possible for a single panel to secure a number of trailers/containers in a storage site
by placing a single camera in each one.
 Unattended vehicles and equipment are targets of tampering, sabotage and theft.
Cameras placed inside the cab or engine compartment resolves this and gives an early
warning of a potential incident.
 Hazardous material areas need immediate security at an accident site, exactly what
this system provides.
 Temporary installations for command centers, convoys, and special open air events
can now be installed in minutes, even in multiple buildings, by a single person.
 Remote infrastructure is subject to both theft and sabotage. Totally wireless video
provides security while enabling the appropriate form and level of response
depending upon whether the video shows an animal, children or something worse.
Conclusion:
Sophisticated totally wireless video surveillance systems are becoming less expensive
and moving from military to commercial applications. They are becoming more common
in large construction projects, mines, large public gatherings and festivals. However,
cost-effective video security opens new markets where totally wireless surveillance
systems are still too expensive. It creates a new “mass market” for video security where
most construction sites, commercial buildings and even residential applications are viable
prospects. In addition, because it is so extremely cost-effective, Videofied enhances
more sophisticated video surveillance systems by enabling a user to place “more eyes in
the field” giving redundancy and better video coverage than can be accomplished by a
single system. Surveillance cameras mounted on a single mast simply cannot cover all the
areas at risk within a job site. They cannot see inside of buildings or look around corners.
Multiple portable P-Cams can be placed and moved anywhere to deliver short videos of
intrusions so that surveillance operators know where to look and what to look for with
their sophisticated high definition cameras. The other traditional method to secure these

sites has been with security guards. Guards are expensive and can only be in one place at
a time. Video security acts as a force multiplier to maximize the efficiency of a single
guard by alerting them of an intrusion and providing video of what or who they are to
pursue.
