You might be asked to set a fixed (static) IP address for the camera on your home wireless network. we talk about how (in most cases) your wireless clients obtain an IP address (when on your network) through the Dynamic Host Configuration Protocol (DCHP). DHCP just gives you an address based on the next one that happens to be available on your network; it can change from time to time.

However, to access the camera from outside your home, say from your office, you want that IP address to be the same all the time so that you don’t have to guess what address it obtained from your DHCP host. When setting up your camera, it will probably ask you to give it a fixedaddress on your network. To do this, simply choose a number outside the range that’s governed by your host’s DHCP client range. If you let your router assign DHCP from within the range of numbers from 192.168.254.0 to 192.168.254.50, you can pick any number above 50 and below 254, such as 192.168.254.100. You need to make sure that you don’t pick a number being assigned by the router’s DHCP, or you might find that your number gets taken by another assignment. The wireless communications doesn’t have to be 802.11b, although we would argue that it makes sense to use standards-based gear when you can. Danny likes his X10 FloodCam that videotapes all activity around the house, night or day, and sends the images to a VCR or PC. That system uses 2.4 GHz to send the signals, but it’s not standardized wireless LAN traffic. Over time, we believe that many of these systems will move to 802.11 or Bluetooth when those chip and licensing costs continue to come down.Wireless Security Camera System

Controlling Your Home overYour Wireless LANAnother area of wireless activity is home control. If you got excited about going from the six remote controls on your TV set to one universal remote control, you ain’t seen nothin’ yet. (And if you still have those six remote controls up there, we’ve got some options for you, too.)

The problem with controlling anything remotely is having an agreed-upon protocol between the transmitting functionality and the receiving functionality. In the infrared (IR) space, strong agreement and standardization exists for remote controls among all the different manufacturers, so the concept of a universal remote control is possible for IR. (IR remotes are the standard for the majority of home audio and video equipment.) But in the radio frequency (RF) space, there has not been the same rallying around a particular format, thus making it difficult to consolidate control devices except for within the same manufacturer’s line. And then you have the issues of controlling non-entertainment devices, such as heating and air conditioning, security systems, and so on. Those have different requirements just from a user interface perspective.

Wireless IP Camera

If you have this,Wi-Fi Home Security Alarm Camera System,These problems are solved.
Keeping an eye on your home is simple, even thousands of miles away. Just hook up the 3G Wireless Camera ( JH09 ) and leave it running. You can check at any time through your smartphone to monitor your house and you can relax in the knowledge that should anyone break in you'll instantly be alerted with frame grabs of the intruders sent to your mobile. In peace of mind you could check what is happening in the house through 720P live video stream. Even when the power is cut off, the internal battery is ready for up to 4 hours’ usage to detect abnormal motion/voiceaided by the PIR sensor.
