2. Security is a degree of resistance from harm. Harm can come in many
forms, may it be physical or monetary. We use security to protect what
we value the most in our lives. Security is a desired state of mind, but it
can be difficult to understand all the technology that provides security,
whether it be office security or home security. Here are a few types of
security to protect what you value.
3. Fire alarm
Fire alarms offer security from fire through the use of lights and sirens.
Fire alarms can be automated or manual. Manual fire alarms require
someone to pull a lever to activate the alarm, which sends signals to all
the campus’s alarms to activate. Manual fire alarms are typically found
in schools. Automated alarms activate when the sensor senses
uncommon conditions; for example, a smoke alarm will activate when
sensing carbon monoxide, and a heat alarm will activate when it senses
significantly high room temperature.
4. Closed Circuit Television
Closed Circuit Televisions, or CCTV’s, are cameras that point to an area
needing protection, such as an entrance or item of value, and send its
capture to a monitor to be monitored. CCTV’s are on a closed circuit, so
the capture that the camera picks up will not be displayed anywhere
other than desired monitors. The CCTV system can also be setup to
record, so a person constantly monitoring the display is unnecessary.
5. Access Control
Access Control is a method of controlling who may and may not enter a
location. The most primitive technology we have in our homes for
access control is locks on our doors. A little more advanced is the
automatic garage door opener. Businesses can opt for a Access Control
method by setting up a some type of data entry panel that requires
people trying to access have a password or pin, biometrics (retina scan,
facial recognition, or fingerprint), or a token (a keycard or a badge with
a Near Field Communicator on it).
6. Fencing
Fencing is a primitive method of security, but can be done correctly.
Fences can allow people to stay out if they aren’t climbable, and fences
that are climbable can be fitted with anti-climb countermeasures, such
as anti-climb paint, spikes, or barbed wire. The higher the fences, the
harder it is to circumvent. According to Coastal Protect, professionals in
home security, it’s also important to look for obstacles that can assist
with circumventing, such as nearby dumpsters, trees, or close
buildings.
