Protecting what
matters most

When it comes to protecting your home and loved ones, you want a security system that is tailored to your specific needs. Don’t sacrifice security for convenience.

Securing your
smart home

More than a smart app or a cool thermostat, CSI seamlessly connects your security, lights, locks, thermostats, video and more — for seamless automation and control.

Each system is customized to your home’s unique configuration and your needs. Our team of experts will find and design the solution that’s right for you.


Window Sensors
They can notify you if a window is left open and communicate with your thermostat to help modify the temperature setting if left open for too long.

Light Control
Manage lights with automatic schedules, and set rules to have lights automatically turn on in an alarm event for added visibility and safety.

Garage Door 
Always forgetting to close the garage? Get an alert if the garage is left open, and close it from your app.

Doorbell Camera
See who's at the door with live video and two-way voice. If you’re not home, you can speak to your visitor and even unlock the door for your trusted guests.

Image Sensor
See what’s happening when motion is detected. The image sensor snaps a picture and sends it to you, so you’ll know what’s happening.

Temp Sensor
Add a temperature sensor to any room for added temperature optimization.

Water Sensor
Don’t let water leaks go undetected. Get alerts if a leak is detected and avoid potentially costly water damage.

Smoke & Co2 Detector
Protect your family with safeguards for dangerous conditions. In the event of a fire, the system signals for emergency response. If carbon monoxide is detected, it shuts down the HVAC to limit circulation.

Smart Thermostat
You can keep the family room comfortable on the weekend, make sure the nursery is exactly the right temperature at naptime, and have the whole house drop to a savings setting when nobody is there. The Smart Thermostat uses all the security sensors around the home so it can automatically respond to different conditions and activities.

Outdoor Camera
Know what's going on outside your home without having to leave the couch. Weather-resistant, freeze-resistant and UV protected, with a wide field of view and night vision.

CSI has made all the difference in the world. Out the gate, they have been amazing. I feel totally taken care of and my rep has taken a truly consultative approach to help us navigate our system. He showed up with a technician during the install and was very patient even with all of my questions. Calling their monitoring system is great and the team on the phones is quick, professional and friendly. I highly recommend CSI!

They have great customer service and good attention to detail. It's nice to have a robust security company with the Mom and Pop feel. They have the ability to dispatch their own armed security patrol to check out your property, which let me tell you really saves on False alarm bills. I have recommended them to other people and will definitely continue to do so.

The main aspects that drew us to them were two things: price and the no False Alarms. I signed immediately on the day that I met them and luckily did not have to look back. While there were one or two hiccups on the path to completion, CSI staff and owner addressed everything above and beyond our expectations! Because of all these qualities, I could not recommend a better service in the Los Angeles area for security systems.

Professional people of the highest integrity, at a very reasonable cost. Courteous staff; always on-time, recommending, installing, and monitoring all that you need, and not more. They installed Security cameras, both closed circuit, as well as cloud Ring (various units).  This tied it with Door and Window alarms has kept our property safe. I highly recommend them.

CSI Security provides responsive service, great value pricing for monitoring of our burglar and fire monitoring services.  They stand by their motto of No False Alarm Fines and if it does happen, they reimburse and ensure that our equipment and monitoring are up to code.  Angelia is a great listener.
