How to increase the range of a wireless camera?

option 1
A wireless range extender takes the signal from the main wireless router and re-emitted, increasing the wireless range. If you put one or more extenders in a strategic point home, you can reach problem areas. However, discretion should be used because it reduces by half the bandwidth between the central router and the remote computer.

option 2
Wireless N technology uses multiple antennas to increase speed and eliminate areas without wireless coverage. Today, it is the most advanced wireless technology and the recommended solution for most situations.

option 3
Powerline is a technology that uses standard electrical wiring to transfer data. To create a network point, simply connect one Powerline Adapter into an electrical outlet. It is the ideal solution for special cases that require high bandwidth and wireless solution is not feasible, for example, streaming video to a basement.

Length of antenna won't significantly affect range, in fact your antenna should be 1/4, 1/2. Now a simple calculation tells you ideal antenna length is between 6-7.5 cm or 12-15cm.

Right next thing is your 900 MHz (33 cm) band is rather busy, and there will be a lot of interference, both cordless phones and wifi as well as PTT walkie talkies being run on this frequency. So it would be an idea to switch it onto a higher frequency in the 1GHz region.

In terms of boosting the power, if the transmitter is built into the camera itself you're going to have to think of a way round it, such hooking the camera up to a separate more powerful transmitter.
