To connect the CCTV cameras, it is necessary to use a power source
providing the appropriate voltage and current depending on the project as a
whole. In this article, you will learn how to choose the right power supply for
your surveillance camera.
In most modern installations with analog cameras, power is centralized
and distributes power to all installed cameras. This type of power supply can
be used to connect several cameras according to their maximum current.
Connection is extremely simple
as there are labels on each of the connectors, the power supply must be
connected to a power outlet using the connectors, and the positive and negative
connectors are connected to the cameras. There is also a connector for
grounding.
It is recommended to use a power supply with a maximum capacity of 80%
to avoid any overload problem. When the system is turned on, there is an
initial peak current which can compromise the source if it is too close to
maximum capacity. For a video surveillance project, it is necessary to know the
current (amperage) consumed by each camera in order to be able to use the
appropriate power supply.
This information can be found on the camera label or in the
installation manual. In some cases, there is information on the power supply in
W (watts). It is therefore sufficient to carry out the conversion by simple
division calculation. From there you can calculate which current is used.
Now that we know how much current is needed for one camera, just do
the same for the others and add up the total number of cameras that will be
used in the project to calculate the power needed, not forgetting to use 80% of
the capacity.
Some explanations on image
resolution.
No matter what combination of analog or digital surveillance equipment
a company has, it is always good to know how it works. The functionality of any
CCTV or IP camera focuses on two things: image resolution and field of view
(what area is covered on the screen).
The video resolutions currently
available.
There are many subdivisions within the categories of video
surveillance systems according to the number of pixels, the size of the screen
and the panorama (field of vision).
The reason why no table dealing with video resolution comparisons
would be complete without an analog section is that there are still a lot of
low definition analog systems in use. They are often the only choice for a
small business. Cameras using analog technology are often integrated into
digital systems as a hybrid surveillance security blanket.
Cameras capable of operating at an angle of 180 or even 360 degrees
have also been improved. The video resolution of these applications will also
be provided in the table.
The terminology and numeric parameters listed below describe the size
(resolution is measured in pixels), how it is transmitted, and how it is
stored.
Best pharmacy safety practices.
Pharmacies are a tempting target for criminals. With the circulation
of cash and large quantities of controlled substances, pharmacies are often the
target of theft. A quality security camera system can be a valuable tool for
loss prevention, management assistance and helping you meet regulatory
requirements.
Go to the local requirements
page.
The recommendations or requirements for surveillance cameras in
pharmacies vary from region to region. In addition to other measures required
or recommended by your local licensing agency, high-resolution cameras can
provide indirect benefits such as lower insurance costs, or better confidence
from your customers.
Show your protection.
To get the most out of your security camera systems in Chicago,
you need to make sure your cameras are visible and that signage signs are
posted throughout the pharmacy. Some traders may adopt the theory of
"hidden cameras", but security cameras are more effective in
preventing theft when potential perpetrators know they are being watched. In
addition to the usual entrances and exits, the cameras must monitor all the
places where the medicines are stored, dispensed, counted, kept or put back in
stock.
Adopt the most modern features.
When thinking about the features that your security camera system needs,
it is important to think about how the potential sequences can be used. From
images of security cameras that we often see in the news or on YouTube, it
seems that many business owners are content with the "just enough"
approach.
However, grainy images and poor quality cameras will not help protect
your business in the event of theft. Our technicians work with you to map your
location to ensure that your cameras have an adequate field of vision and cover
all areas for your security needs. With a wide range of cameras with special
functions such as panoramic zoom, wide-angle lenses and infrared sensors, we
can design a set of cameras that will best meet your security needs.
3 main security controls of a
warehouse.
Warehouses face many problems: contraband, theft and even terrorist
activities, all pose potential risks, and can threaten the financial and legal
well-being of your business. This is why warehouse owners are generally known
for their strict and effective security practices.
The importance of warehouse
security.
Warehouses are very visited places, daily logistical problems often
take a long time to resolve. However, it is essential that warehouse staff and
owners take safety and productivity into account. Follow these instructions to
stay on top of security risks.
When it comes to warehouse security, the first thing you want to
control is who has access to the facility, and when access is granted. In order
to monitor this, you need to have an effective video surveillance system, if
possible with face recognition. Security, however, should not start at your
warehouse door. Obviously, your perimeter must be secured with a fence and a
checkpoint. Vehicles should always be watched and parked away from cargo areas.
Pickups and deliveries should only take place in designated areas with adequate
security measures.
2. Installation of
cameras.
An effective warehouse security plan relies heavily on the security
technology in place. Surveillance cameras covering all sides, possible
entrances and exits are essential for warehouse security. Monitoring systems
must be maintained 24 hours a day, with image storage for at least 30 days. To
ensure that you can recognize the people recorded on your cameras, it is
important that your system is installed by a team of professionals. Factors
such as positioning, programming and the type of security camera are not as
easy to determine as you might think.
3. Train your employees in safety.
Security, surveillance and threat awareness are not to be overlooked.
In order to guarantee the security of your warehouse, it is necessary that all
of your staff understand their security responsibilities. Communicating the
importance of security checks to your staff is essential for the processes of
receiving, processing, storing and sending filmed images. Employees are much
more likely to report threats if they understand why and exactly how to do it,
because even small threats can report a potentially compromised shipment or
turn into dangerous situations. It goes without saying that regular fire, alarm
and natural disaster drills are essential.
