What Our Customers Say

Don't just take our word for it - read what our San Diego customers say about Smart Shield Systems.

Google Reviews 4.9(106 reviews)

“We had an old ADT panel that was constantly false alarming. Yud came out, replaced it with a Qolsys IQ4 panel, and moved all our door and window sensors over. He added a glass-break in the living room and programmed the app so we can arm from our phones. No more 3 a.m. false alarms. Very clear about what we needed and what we didn’t.”

Maria T.

San Diego, CA

“Smart Shield installed 12 cameras around our warehouse and loading dock in Chula Vista—eight outside, four inside. They ran the cables properly and set up the NVR so we can pull footage by date and camera. We had a break-in attempt a month later and had clear footage for the police. Exactly what we needed.”

James R.

Chula Vista, CA

“We have three rental units in Escondido and were tired of driving over to hand off keys. Smart Shield put in smart locks on all three units and set up temporary codes per tenant. We get a log of who entered and when. Turnover is way easier—we just send a new code. They explained the hardware and left instructions for our property manager.”

David & Lisa K.

Escondido, CA

“We already had sensors and a panel from the builder, but no monitoring. Smart Shield added 24/7 alarm monitoring and set up the app so we get alerts and can arm/disarm from the phone. We had one real alarm when someone tried the side gate—central station called and we could see the zone. Peace of mind for our coastal place.”

Patricia L.

Carlsbad, CA

“Yud and his crew tied our existing alarm into our smart home. We can now arm the system, lock the front door, and turn off the lights with one “Goodnight” scene on Alexa. They added a Z-Wave thermostat so it backs off when we arm Away. No more separate apps—everything is in one place. Took a half day and they left it all working.”

Tom S.

La Jolla, CA
