Yes it can. You can either get it as a Toyota accessory or you can have a shop add it on with an after market system. It is more complicated due to the Smart Key system, but it can be done.
I would get the Toyota system simply because it is controlled by the Smart Key and does not require an additional remote.
Others like after market because some have additional features, have a longer range, and have a lower price.
If you do go after market- make sure your shop has a good reputation, is insured, and offers a good warranty. The TCH is a complex vehicle, and you don't want them to screw up the electronics.
Good luck.
P.S.- try searching using different words or combinations. I searched a few times and got about 17 results in the Camry Hybrid forum alone. Also try looking at
www.greenhybrid.com too- lots of good information on that website.
