Video-monitoring for Municipalities
Increased security required by citizens in
municipal environments requires a full
development of video surveillance and
security solutions that are able to:
– Connecting and manage a variety of remote locations with different types of cameras.
– Generate video images of high quality for subsequent storage and analysis.
Atizapan de Zaragoza is one of the 125 municipalities in the State of
Mexico. It has an area of about 90km² and a population of half a million
residents. This urban municipality is part of the metropolitan area of Mexico
City.
The Public Safety Department of Atizapan Municipality has launched an
ambitious public project for citizen security throughout the municipality,
given the high levels of crime in the area. With this deployment, the C4 or
CIMA (Center for Intelligence and Monitoring Atizapan) receives and
stores real-time videos from 304 CCTV cameras located throughout the city.
The partner company that has deployed the project is Jomtel, a reputed
integrator in the sector of public security, which has provided turnkey
Albentia Systems technology that meets the most demanding solution.
About the Technology
Albentia Systems, Spanish pioneer
manufacturer in the sector of wireless
broadband, presents, with his partner in
Mexico ,Jomtel, a solution for digital
video-surveillance networks based on
IEEE 802.16 technology.
Albentia Systems implements robust and
reliable solutions, able to operate in
highly interfered outdoor environments
and under the most demanding climate
conditions.

SUCCESS STORY
The Solution
The solution featured both point-to-multipoint and point-to-point technologies,
since the project required a backbone for transport of all videos to CIMA, as well as
a multipoint network where 304 cameras would be deployed. All base stations,
CPEs and PtP radiolinks in the network were provided by Albentia Systems.
Point-to-multipoint access network for IP cameras:
The 304 cameras were distributed in 76 poles located in the avenues and major intersections. On each pole there were 4 cameras, 3 fixed cameras and a PTZ were installed on each pole and they all had night vision. The cameras were connected by a switch to an ARBA Pro CPE with an integrated 20dBi antenna. The same CPE connected multiple IP devices, facilitating deployment and minimizing costs.
76 CPEs were wirelessly connected to various base stations distributed around 5 communication towers. In total there were 22 ARBA Pro base stations. Albentia Systems worked with the integrator to optimally design the network, taking advantage of the variety of antennas available for the base stations (60°, 90° and 120° integrated or external antenna).
All towers had more than one base station and ARBA Link transport device, so 8 synchronism units were installed to avoid co-channel interference thanks to Albentia Systems’ true TDD technology.
Point-to-point transport network from towers to the Intelligence and Monitoring Center in Atizapan:
In order to get all the videos to C4, 11 ARBA Link radiolinks were installed. In the design process, network load was studied to assess whether it was necessary to install the 150 Link model or the 350 model, depending on the required capacity.
Some towers had no line of sight with the C4, so alternative points were used for intermediate links.
The Challenges
The principal objective of the project was to establish an effective surveillance and
public safety system that allows real-time monitoring key locations in the
municipality and recording images for later crime analysis.
The project was ambitious because it required video-surveillance in avenues and
principal intersections in the town, both day and night, and included a system for
citizens to activate an alarm in case of danger. The images and alarm signal had to
arrive at CIMA, so the network had to be stable and secure 24x7, and invulnerable
to falls, delays, packet loss or pixilation. For such critical security purposes, an
unprofessional wireless technology would not be suitable.
The project required an easy deployment that allowed the municipality to save
costs in terms of time and resources. The equipment had to be rugged and robust
in order to perfectly operate outdoors and in a highly interfered urban
environment, so the project needed a high spectral efficiency solution that could
provide special protection against interference.
Finally, another fundamental challenge of the project was to achieve maximum
transmission security, to prevent the interception of images by anyone other than
the management bodies of municipal entities.
Synchronism Units (SCUs)
An SCU is a device designed for
synchronization and managed power
supply of base stations and radiolinks.
Each SCU allows feeding of up to 4
devices and, thanks to its managing
capability and its connection to the data
network, it is possible to check what
devices are being fed, stop or activate
this power supply, and monitor each
port’s power consumption.
Thanks to its synchronism signal
generation system, the SCU allows
installation of multiple radio devices at
the same location, completely
suppressing interference between them.
