wired security camera system offers more
stability than wireless cameras, as you’re
not relying on your Wi-Fi network for
video transmission (plus there’s no interference from nearby devices). But wired
security cameras are more difficult to
install, often requiring you to drill holes
and fish wires through walls and floors to
connect to a DVR or network video
recorder. If you’re planning to stay in
your home for a long while and don’t
mind hiring a professional to install it,
a wired solution may be right for you.
Wireless cameras, on the other hand,
are much easier and quicker to install
since you can use them in more places,
and they don’t require a cable to run to
the DVR or internet modem/router.
However, unless they’re battery or solar
powered, wireless cameras will still need
a source of power, such as a nearby AC
outlet. As you might expect, wireless
cameras can be more expensive, but
almost all work out of the box with an
app for remote viewing.
Several smart options
can help keep your
home safe when
you’re not there

tationing one or more video
cameras in your home is an ideal
complement to an alarm system.
There’s peace of mind in knowing that whatever is happening in or
around your home is being captured,
saved or shared.
These internet-connected cameras
let you see when the kids come home
after school, what your pets are up to all
day or if something unwanted is happening. Here are a few considerations to
help you decide which camera system is
best for you.
How many, and where?
One of your first decisions is whether
you want one camera, such as a video
doorbell to see who’s approaching your
home, or if you’d like a whole system
of cameras to place in and around
If it’s the latter, these cameras often
connect to a digital video recorder (DVR)
to store the captured footage onto a hard
drive (or sometimes a flash memory
card), just in case you need it.
Of course, weatherproof cameras are
required if you’re buying for the outside
of your home, as these are more durable
in order to withstand the elements.
Wired or wireless?
Wired and wireless solutions each
offer pros and cons. Generally speaking, a
Costco o;ers a variety of security
camera systems in the warehouses
and online at Costco.com.
Here are a few extra things to
look for in a camera system.
• Not all cameras let you
see footage remotely, so be
sure to look for this feature if
it’s important to you. Internet-
connected cameras can be
set up to send a notification
to your phone if they detect
motion or sound. Be aware
that some apps might charge
a small amount to store your
video online (in the cloud).
• Some internet- and
app-enabled cameras o;er
two-way voice support to talk
with whoever is home when
you’re not (or the other way
• Some camera systems
o;er ultra-sharp 4K video
quality, matching the resolution of newer televisions.—MS
