Smart security is

smart business

With professionally monitored security, access, energy management and video monitoring solutions, you get peace of mind knowing that your business properties are protected and running smoothly — all from one app.


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
Automate your lights so that the proper areas of your business are well-lit during business hours and security lights are always on after hours.

Access Control 
Easily manage employee permissions for all the access points at your business. Quickly add or delete users, restrict entry to sensitive areas, and receive notifications when these areas have been accessed.

Exterior Camera
Watch live-streaming and recorded HD videos from the app. You can view multiple locations in one dashboard and easily jump right to a specific clip to see exactly what you’re looking for.

Image Sensor
The image sensor snaps a picture when motion is detected - such as when someone enters the office or moves behind a desk – and sends it to you.

Temp Sensor
Place temperature sensors in any area of the business where you need to optimize the temperature. This can also help regulate the temperature in areas that are otherwise prone to being too hot or cold.

Smart Locks
Fully integrated commercial-grade locks help keep offices, stock rooms, and delivery doors secure. Easily assign unique lock codes for employees, or remotely lock and unlock doors for staff and deliveries at any time.

Rear Video Camera
Get extra visibility for secluded or hard to monitor areas, such as the rear entrance.

Door Sensors
Know whenever a sensitive area of the business – such as an office – is accessed, and know if there’s activity when there shouldn’t be.

Dome Camera
Get 360-degree visibility in the heavy traffic areas of the business. With 24/7 recording and cloud hosting, you can have confidence that your video footage will be safely stored and accessible when you need it.

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.
