These days, a wide range of security camera equipment and capabilities exists which can make any security surveillance system extremely able and highly functional.

Many wireless systems exist which make use of different means of getting their image signals from the camera to the receiver/monitor/recorder devices.

WiFi is now one of those.

For those who don't know, WiFi stands for "wireless fidelity." It's actually a trademark that belongs to the WiFi Alliance and the use of its name is allowed for certain products that have been certified and which are used within a class of wireless local area network (WLAN) devices.

The manufacturing of these devices is based on IEEE 802.11 standards published by the IEEE LAN/MAN Standards Committee.

Basically, any device wishing to make use of wireless fidelity technology has to meet the standards put out by that committee if it hopes to sport the "WiFi" logo, which is visible on any device, either on its casing or in its accompanying literature.

Adding WiFi security cameras to an already existing home WLAN (WiFi local area network) is relatively straightforward, as well.

Think about it; there's already a nice secured and encrypted home network operating smoothly.

All the desktop and laptop computers are joined to the network and there's even an existing intruder alarm in the home. But what about the outside areas?

Sure, buying a new and separate video surveillance security camera setup could work, but it can cost a lot from a complete set-up especially if you just want something covering one or two locations.

Purchasing a very nice WiFi-enabled security camera with a 250-foot transmission range and a host of other features can make a lot of sense.

For a lot less than a full system you can get one or two WiFi (or IP) cameras

And consider what they can do; for one, they're capable of being accessed from certain mobile support platforms, meaning a look can be taken from a video-capable cell phone.

Additionally, they can take a picture if someone or something – when the camera's equipped with motion sensor ability – and send it to a person's email, complete with a JPEG (picture) attachment.

They can also be managed remotely through certain well-known networks as well.

They also can hook into most popular Internet web browsers including IE, Firefox and Safari on both PCs and Macs. This is an extreme versatility.

Like anything else that has to do with wireless networks, it's important first of all to make sure the WLAN is secured and protected via means of strong encryption.

Also keep in mind that these cameras are making use of radio frequencies, so there's always an issue with radio interference.

And a camera that fails to send a strong enough signal to the server is just useless, so always ensure that any camera is rated for at least 250-feet of broadcast strength.

If thinking about buying a few of these cameras, make sure they come with the ability to make use of the browser that the household is most familiar with.

Also, they should be able to see images in at least low-light conditions as well as the ability to send remote notifications via email in the event there are any issues, either with the camera itself or in the event it detects motion in front of its field of view.
