You love your pets. I know I sure do. My dog is a very important
part of my family and I hate having to leave him alone all day
while I'm at work. That is why I installed what I call the 'PetCam'
- a web enabled IP camera that allows me to check in on my dog from
any location via the world wide web. And guess what, it turns out
that Fido is quite busy while I'm away - and he has an incredible
internal clock - he gets very agitated about an hour before I
return home from work - who knew!
Installation of a web enabled Pet Cam is actually quite easy to
do. The first thing you need is high speed Internet. Sending video
over the web requires both speed and a healthy bandwidth allocation
from your internet service provider, so make sure to check with
your ISP on any existing bandwidth caps. Both Cable and DSL
Internet services are idea for this application.
Next, you will need a router to which you will connect your
internet camera. If you want the freedom of a wireless IP camera
(recommended), a wireless router will be required. Most IP cameras
come with a CAT5 Ethernet connection, but who wants cables running
all over the house! This article assumes that you already have a
router installed and functioning with a high speed Internet
service.
Now comes the fun part - choosing the right camera for the job.
Because we are looking at transmitting video over the Internet, the
best choice is an Internet IP camera. Do not confuse these cameras
with a webcam. Although they might look similar, Internet cameras
are a small computers with a built in web server. Unlike a webcam,
they are independent entities that do not require an external
computer to function. They are the ultimate independent
contractor!
Keep in mind that most Internet IP cameras work with CMOS video
sensors, therefore even if night vision is offered, it probably
won't work very well - these cameras are meant for well lit
applications.
I strongly recommend the Linksys WVC54GCA and DLINK DCS950G
Internet Cameras - both are great entry level IP cameras that will
get the job done and can be purchased at a reasonable cost (between
$100 to $150 US dollars). More advanced (and expensive) models add
features such as Pan and Zoom - nice to have features, but not must
haves.
If you already have a DLINK or Linksys router, it may be a good
idea to stick with the same manufacturer for your Internet Camera
as the included documentation will provide more specific router
configuration information.
OK, so how do we get this remarkable little device to broadcast
video to the Internet. The first thing we need to do is configure
the new internet camera. This usually involves establishing a wired
connection to the camera from your router. You then load the
configuration software onto your computer and proceed with the
setup as specified by the documentation.
The first thing the software will do is detect the new camera
and have you specify a unique IP address for the device - try to
avoid using DHCP, as a static IP address is preferable. If you are
using a wireless camera, you will need to configure the wireless
settings for the camera, including any security passwords for WEP
or WPA. Additionally, you will need to identify and document the
port number used by the camera to communicate with the outside
world (some cameras let you choose the port).
If your internet service does not have a static IP address, you
will need to open an account with a dynamic DNS service provider
such as DynDNS.com. This service provides you with a free domain
name which will automatically detect any changes in your home IP
address. Most cameras will have a configuration page where you can
enter your dynamic DNS settings.
All that is left is to do is open a port on your router, a
process referred to as port forwarding. This will allow the camera
to communicate with the outside world in a secure fashion.
This may all sound a bit complex, but it is actually quite easy
to do if you are even mildly tech savvy. If you need assistance, a
quick call to your local Nerds on Wheels service should have you up
and running in no time at all.
