How Many Home Security Cameras Do I Need?
If you’re thinking about installing a CCTV system in your
home, one important thing you need to figure out is how many security cameras you
will need. Not having enough cameras means that you won’t be able to monitor a
lot of areas, but having too many cameras is a waste of money. It can be a
confusing task to figure out the right number of cameras, but this post will
break down everything you need to know.
Why It Matters
When people are first installing a home CCTV system, many of them skip
on figuring out how many security cameras they will need and decide that
they’ll just add more as time goes on. Doing this might save a little bit of
money now, but it’ll end up costing more in the long-run. For example, if you
start off buying 3 security cameras and a 4 channel NVR, you’ll only be able to
use a total of 4 cameras. If you decide that you want to add 2 more cameras in
the future for a total of 5 cameras, you’d have to buy a new NVR to support
that 5th camera. Additionally, if you don’t determine what areas you want to
monitor now, you may end up buying cameras that are not suited for your
purpose. If you can determine how many and what type of cameras you need now and,
in the future, you’ll be able to avoid problems like these.
Determining How Many Home
Security Cameras You Will Need
Purpose of Surveillance
Before you buy any home security cameras, you should first think about
what you will be using the cameras for. Determining the purpose of your
security cameras will allow you to figure out how many cameras will need for
each area. For example, if you will be using the cameras to monitor for any
crime, you should opt to buy more outdoor cameras. If you want the cameras to
keep watch over your family or pets, you should use more cameras for indoor
usage.
Areas of Coverage
After deciding your purpose, the next step is figuring out which areas
you want to place the home security cameras. To make things simple, you could
make a list of all of the rooms and areas inside and outside of your house.
Then check off all of the places where surveillance is absolutely essential.
Most people choose to use security cameras for areas such as:
- Front of the
house, including the front door, walkways, driveways, and attached garages
- Backyard,
including any points of entry like any backdoors or gates
- Nursery/child’s
room
- Family room
- Rooms with
valuables
In general, most homes will only need a system of 4 cameras:
- 1 outdoor
camera to overlook the front door/porch area
- 1 outdoor
camera for the front yard and 1 more for the backyard
- 1 indoor camera
to monitor children or valuables
Other Factors to Consider
However, keep in mind that not all homes are the same so each one will
require different things. Other factors that you should consider include:
- House size:
Bigger houses may need more indoor cameras since there’s more rooms to
monitor.
- Outbuildings:
If you have extra storage sheds or other buildings on your property, you
may need to buy more cameras to install inside/outside those buildings.
- Property size:
If your house is situated a large lot, you may need more outdoor cameras,
especially ones that can monitor extended distances.
- Type of home
security cameras: If you are using cameras that can see further or can
capture wider areas, you might be able to use less cameras for all of the
areas you want to cover.
Available bandwidth: Having limited bandwidth could affect the quality of your security camera footage so make sure you have the necessary bandwidth to handle your cameras. Reach us out for CCTV Installation Sydney.
