Expert Verdict (2026) - Why Buy?
"The Kenwood DMX40S is the 'Smart-Sized' powerhouse of the Kenwood lineup. At Lockdown Security, we recommend the DMX40S for vehicles with limited space behind the dashboard, thanks to its ultra-shallow chassis design that makes installation a breeze in challenging modern dashboards. It features a crisp 6.8-inch capacitive touchscreen that is significantly more responsive than older resistive models, providing a premium feel for Wired Apple CarPlay and Android Auto. What truly sets the DMX40S apart in this price bracket is the 3.7V high-voltage pre-outs, delivering a clean, powerful signal to your amplifiers for a noticeable jump in audio clarity. Combined with full iDatalink Maestro support to retain your factory steering wheel controls and vehicle data, the DMX40S is the perfect blend of installation flexibility and high-fidelity performance."

Quick Response
Had good experience a few years ago with parking sensor installs (front and rear) for 2 cars. Just got 2 dashcams installed. Duane gave quick responses online with a very reasonable price. Both cars, front and rear cams installed professionally and looks seamless (tech was very informative). Leo and Titus - front desk - took care of things efficiently, answered all my questions in a friendly manner. Got my cars back in the time specified. Very good selection, service, installation.

Extremely Professional
Everyone at Lockdown was extremely professional, knowledgeable and pleasant. They also had the additional hardware I needed rather than ordering it separately beforehand. Leonardo was very patient answering my questions and going through how to set up and use my new Dashcam. Sal was great going over the installation process and asking me questions how I wanted it installed. I would highly recommend their services.

Awesome Experience
Just installed the thinkware q200 dashcam today with awesome experience. Booking the appointment is easy and service is excellent. After the installation, staff also walked me through the set up and everything is done within 2 hours. The cost is same as the website shows and no other hidden cost. Highly recommended. 👍
