Wireless Webcam Comes of Age
Wireless webcams are among the latest in innovations for surveillance, security and personal communication. Originally developed for military applications, a wireless webcam is able to communicate by way of radio signals or through a wireless network and thus eliminate the need for wires connecting the device to your computer.
The range of a wireless webcam can be from 10-30 feet for Bluetooth and up to 300 feet for 802.11 applications. Most have repeater capability that can double or triple the range. Infrared cannot penetrate walls and is line of sight only. Cell technology is not limited by distance.
Wireless webcams have the same convenience and ease of installation of wireless routers. No more wires to pull through messy attics or dirty crawl spaces, plus wireless technology makes moving your webcams a snap.
Your options when choosing a wireless webcam are as numerous as the imagination. Features can include live feed (the ability to see what the camera is pointed at in real time) from a computer, PDA or cell phone, the ability to remotely pan/tilt, night vision, motion activation and built-in microphones.
Some wireless webcams have the ability to send a text message or email notifying you that motion has been detected along with a picture of the area in which motion has been detected.
Another option is to live stream your camera to the internet where you can view, record, share and share your content. Can you say nanny-cam?
Your wireless webcam will need a power source. Battery power tends to be the norm and are generally recharged by connecting them to your computer with a cable. For more remote applications you will want to have a models that can be powered by a constant power source run to the camera. There are even solar powered webcams for outdoor applications.
Another consideration when choosing your wireless webcam is the frame rate. For most webcam applications 16 frames per second is fine. For smoother movements you will want 24 frames per second and if you need to view fast moving action you should look for 30 frames per second.
To be live-viewable your wireless webcam will use your IP address. This is great unless you have a dynamic IP address. If that is the case you may have to use a service that charges a monthly or yearly fee. The ability to send motion detected notification messages is not affected by having a dynamic IP address.
