It looks like the LoJack Car Security System finally has some serious competition in the form of Escort's Entourage CIS and PS, featured at this year's CES show in Las Vegas.

The $399.95 Escort Entourage CIS is installed somewhere in the vehicle, but unlike like the LoJack system, which becomes a permanent part of the car, the Entourage PS can be transported from one vehicle to another. The Entourage CIS can send text messages and e-mails if it senses the vehicle has moved while the owner and the special key fob are away.

Should that happen, the optional GPS security system automatically activates and the owner will get a phone call from Escort. Besides theft-prevention, the technology can also help you track the vehicle's location and, as CNet.com notes, track teen drivers and let them know when they are driving too fast or that they're simply out too late. Ford has a similar idea in the form of its MyKey on the Taurus, which can program the car to limit speed, not to mention set a maximum stereo volume of 45%.

Unlike the Entourage CIS, the Entourage PS is portable. The unit can be hidden in a number of different vehicle locations and will still receive a signal that can be sent to your smartphone or computer. While the Entourage PS is $50 cheaper, it does need to be charged about once a week. As with the CIS model, the PS can send text messages and e-mails as often as the owner wishes.

The portability of the PS is a big plus, but what sets back both of these Entourage products is the required subscription fee. The Blackline GPS used for the Entourage CIS and PS is $179.95 a year. The police-operated LoJack, in contrast, requires a onetime charge of about $600-700 depending on the installer, but no monthly fees. Regardless, it's clear that vehicle owners hoping to track their vehicle or recover it after a theft have more choices than ever before.
