Most companies are not getting all they can out of
their
DVRs (DIGITAL VIDEO RECORDING SYSTEMS). This is either because they
are using outdated technology, they haven't been told how to use all of
the features their systems possess or they simply do not have their
systems set up in the best possible manner.
Following are a few tips on how to optimize a
DVR and get the most out of your system.
In the past, surveillance equipment allowed employees with access codes
to retrieve the same data as a store manager or owner. Today's
access-code technology, however, allows owners to restrict specific
information from employees using certain codes.
Purchase equipment featuring the latest technology. It is well worth the
money spent to purchase the most up-to-date surveillance equipment. A
few examples:
Access Codes. In the past,
surveillance equipment allowed employees with access codes to retrieve
the same data as a manager or owner. Today's access-code technology,
however, allows owners to restrict specific information from employees
using certain codes. For example, a manager who was once able to access
the surveillance camera in his or her own office can be prevented from
doing so.
Computer Security. With a
growing number of people becoming computer savvy, it is harder for
owners to ensure the security of their surveillance system when they are
using outdated technology. On the other hand, modern technology exists
that allows for Windows® features, such as CTRL-ALT-DEL to be disarmed,
thus avoiding system shutdowns by unauthorized people. This same
technology can restrict Internet access, avoiding employee time spent
surfing the Web when they should instead be processing orders.
Silent Send. The technology used
in today's
DVRs allows for a "silent send" -- this is a copy of any information
being downloaded to a back-up disk and sent to a designated area such as
a file on the network main-frame. Owners now have the ability to record
any backups being made by their employees.

DVRs. Modern
DVRs include internal and external monitoring systems that will tell
the owner or manager how many days of recording time are being stored on
the
DVR. They also can send an e-mail message to the owner or manager if
they are no longer receiving a signal from a surveillance camera,
eliminating hours or even days, of lost footage.
Higher-Resolution Cameras.
Megapixel cameras allow owners to capture license plate numbers of
customers at their gas pumps and other details normally lost with
standard cameras, which have only between 300 and 500 TV lines of
resolution. PTZ cameras have to manually jump to location and optically
zoom, plus they capture an image at 640 x 480 resolution and can only
look in one direction at a time. Mega-pixel cameras, on the other hand,
have resolution of 1,600 x 1,200 and greater. Because these cameras zoom
digitally, the entire picture is intact and available, giving both
detail on zoom and wide area shots when not zoomed. With megapixel
cameras, there is no chance of losing the shot.
Have an Overview Shot.
Set
up at least one camera that monitors all critical areas in the bldg.
This footage is important not only for security purposes, but for
liability purposes, as well. By having a clear view of the entire
operation, the owner can avoid situations such as fake slips and falls
where a customer or employee finds an area that isn't captured on video
and fakes a mishap.

Get a quality picture of each customer or employee’s face
at his or her point of entry. Many times, bldg. surveillance systems are
set up to grasp only an overview of the premises.
In
such cases, potential thieves will become familiar with camera locations
and take specific steps to ensure that the overview cameras do not
capture a quality image of their face (i.e. by wearing baseball caps or
keeping their bodies angled at a certain position). This creates an
obvious problem when owners need to use surveillance videos as evidence
in a court of law.
When owners capture a quality facial picture of each customer or
employee at the point of entry, they are then able to use overview shots
as evidence against thieves, vandals and others based on clothing and
other general descriptions from the point of entry and camera.
Integrate Registers with Cameras and
DVRs. Recording the register area and coding the surveillance
video when no-sale and void transactions occur, allows retail owners to
quickly search for and review employee activity during these types of
transactions. Combined with megapixel cameras, owners can then review
the exact currency being handled by the employee, cutting back on friend
discounts and outright theft.
Switch to broadband networks such as cable, DSL or T1 connections.
Modems cannot handle the high-quality images being sent by modern
surveillance cameras. Trying to use a modem for remote viewing is nearly
impossible. When using a cable, DSL or T1 connection, managers and
owners can review employee or customer activity from remote locations
without losing photo quality.
Replace Hubs with Switches. The
10 MB transmittal speed of network hubs and the fact that hubs send data
from each computer to all ports on the hub, can cause issues with the
DVR recording IP cameras, while possibly causing delays in video
speeds and network congestion.
In fact, hubs can create a 30- to 40-percent loss of video streaming on
congested networks. By replacing hubs with switches, which create a
virtual one-on-one connection from surveillance camera to
DVR or from the
DVR to the remote client, owners can increase video streaming from
one to as many as 30 images per second, depending on network speed.
Owners also may find that other internal software using the network
increase in speed, as well.
Clean Your
DVR.
DVRs
are great collectors of dust and other environmental debris, which can
greatly affect their output. In most environments,
DVRs should be cleaned at least once a month. In some environments,
however, where more particles are floating in the air, cleanings should
be done as regularly as every three weeks.
In addition to cleaning the
DVRs, owners should be careful where the
DVRs are stored. Storing a
DVR next to or close to high-amp electric lines will create lines
and other disturbances in the recording. It also is important to make
sure that
DVRs have a proper amount of ventilation to ensure they are working
at the optimum level of electronic efficiency.
Research Suppliers. Not all
equipment suppliers will provide owners with technical advice and
customer service. In fact, some are happy to sell their equipment --
regardless of whether or not a specific product is the best-suited
equipment for the surveillance environment -- and leave the owner to a
trial-and-error process of learning how to use that equipment.
When an owner decides that he or she is ready to update the surveillance
system, they should contact reputable suppliers. An owner can even go so
far as to ask if tech support will be provided, or if paid support will
be made available as needed, and at what price.

lease.
