Keep Your System.

Keep What Works.

You don't need a new security system to get a better security company.

The Biggest Myth in Home Security

Most homeowners assume changing security companies means replacing everything.

In many cases, that's simply not true.

Our Philosophy

At Excalibur, we believe homeowners shouldn't have to replace perfectly good Alarm.com equipment just to receive better service, better support, and modern security features.

That's why we start by evaluating what already works.

If your existing equipment is compatible, we'll recommend keeping it.

Because replacing good technology just doesn't make sense.

What We Can Often Keep

• Control Panel

• Door & Window Sensors

• Motion Sensors

• Glass Break Sensors

• Cameras

• Doorbells

• Smart Locks

• Garage Controls

(Compatibility varies by system.)

What Usually Changes

The company behind your system.

Not necessarily the system itself.

Why This Matters

Keeping compatible equipment can often:

• Reduce installation time

• Reduce unnecessary replacement

• Preserve your investment

• Minimize disruption

• Get you back online faster

Our Specialty

This isn't a shortcut.

It's a skill.

Proper system takeovers require experience, planning, and technical expertise.

It's one of the reasons homeowners throughout San Antonio choose Excalibur.

A Real Example

Recently, we helped a San Antonio homeowner switch security companies while keeping much of their compatible Alarm.com equipment, including perfectly functional, hardwired, sensors from 15 years ago. 

Instead of replacing a perfectly good system, we focused on improving the service behind it.

That's what "Keep What Works." means.

Questions We Hear Every Day

1. Can I keep my security panel?

Many Alarm.com-compatible panels can remain in service. We'll evaluate your system and explain your options before recommending any replacements.

2. Can I keep my cameras?

In many cases, yes. Compatibility depends on the camera model and platform.

3. Can I keep the Alarm.com app?

If your compatible equipment remains on the Alarm.com platform, you can continue using the Alarm.com app.

4. Will I need any new equipment?

Sometimes. If certain devices aren't compatible or have reached the end of their useful life, we'll explain exactly why and recommend only what's necessary.

5. How do I know if my system is compatible?

That's exactly what the Compatibility Assessment is for.

6. Does this cost anything?

Your Compatibility Assessment is complimentary and comes with no obligation.
