IP security cameras..?

I have been looking at some security cameras on ebay... specifically the ip type that I can monitor from anywhere... All the units I have looked at seem to come with an ethernet cable...... why do I need this ?? I thought I would only need a power lead ??

    How exactly did you imagine they would connect to the net without an ethernet cable? (otherwise known as a network cable or a cat5)

    You plug the power in, plug the ethernet into your router (and the other end into the cam) and i'd imagine you will have a CD with instructions to follow to connect to the cam and configure it.

    If its wireless, you'll be connecting it with ethernet and then it'll be configured and you can remove the ethernet cable.

    OK, so I am usually a jerk on questions that are stupid, but this might be a legit question!! I know; holy crap.

    Most people who are running cams like this don't want a bunch of cables and having an outlet next to every cable is a pain. There is a protocol called Power Over Ethernet or PoE. This means that the power to go to the cam also goes over the network cable allowing you to have a single cable that handles the data and runs the cam.

    To make this work, you either need a data switch that is able to run PoE (expensive - in the $8-16K range) or you use power injectors that put the power onto the cable. The PoE cams are the good ones and will generally be a better choice than externally powered cams.

    Of course, if that was not the question.... yes you need a DATA cable to get all the 0's and 1's that make up the pretty pictures to your monitoring station. Otherwise, they fill up the cam and spill onto the floor causing a slip and fall hazard.

    Answers on here are a little arsey..?

    Basically the Eithernet cable connect the cam to the network to tansmit the images, like a dvd player, you need a cable to power the unit and a cable to transmit the image to the tv...

    If you plug the cam into a network that is connected to the internet, then you will be able to view what the cam is picking up, software my need to be installed!

    Im not an expert in this field but if you need help with anything or want something explained, please feel free to email me on

    The camera needs to connect to your network in order to be accessed via the internet. The Ethernet cable allows for such a connection. Without that cable (assuming it doesn't have wireless functions) it cannot be accessed via a network, including the internet.

    if it is an IP camera it must connect to the internet. This could be wireless or cable.

    He tenido buenas experiencia con los productos de sitios web, había comprados cámara muy buenas a un precio muy bueno, como viajo mucho he comprado y una cámara para el coche porque nunca se sabe cuando la necesitas, la cámara va perfectamente, buena resolución y un buen ángulo, aunque a lo mejor no me haga falta, a este precio es mejor tenerla porque es muy utilla.

    How else are you going to receive an image? Hate to sound 'arsey', but c'mon!

    It's to connect them to the network so you can see them from everywhere.
