What’s Actually in a Burglar Alarm System?
Control Panel
The brain of the system. It processes signals from all sensors and triggers alarms. Professional panels (DSC, Honeywell, 2GIG) are more reliable and expandable than consumer panels. This is the piece worth investing in.
Door & Window Sensors
Magnetic contact sensors on every exterior door and window. Standard homes need 6-12 sensors. $15-40 each. These are the foundation of any alarm system.
Motion Detectors
PIR motion sensors cover interior spaces. Most homes need 1-3 depending on layout. Pet-immune versions available so your dog doesn’t set off the alarm. $30-80 each installed.
Glass Break Detectors
Detects the frequency of breaking glass — catches intruders who break windows rather than opening them. One per main living area is usually sufficient. $50-100 each.
Keypad
Where you arm/disarm the system. Touch-screen keypads with app integration are standard now. Typically 1-2 per home.
Siren / Sounder
Interior and exterior sirens. The noise is a deterrent — most burglars leave within 60 seconds of an alarm activation.
Do You Need Monitoring?
Professional monitoring means a 24/7 dispatch center watches your system and calls police when the alarm triggers. It’s optional — your system works without it.
- With monitoring ($15-40/mo): Someone calls police even if you’re unreachable or asleep. Police response time matters. Good for families, vacation homes, elderly relatives.
- Without monitoring: Alarm sounds, your phone alerts, you call police yourself. Works fine if you’re usually reachable.
Our honest take: Monitoring is worth the cost if you travel frequently or have a vacation home. For most primary residences with attentive owners, the alarm + camera system with push alerts covers you.
Burglar Alarm FAQs for Rockwall & DFW
What’s the best burglar alarm for a Rockwall TX home?
For most single-family homes in Rockwall, a professionally installed system with a DSC or 2GIG panel, 8-10 sensors, 2 motion detectors, and app control runs $1,000-$2,000. Add cameras for the complete picture. We can tailor a system to your home in a free consultation.
Does a burglar alarm lower my homeowner’s insurance?
Yes — most Texas insurers give a 5-20% discount for monitored alarm systems. Ask your agent. The discount often pays for monitoring within the first year.
How long does installation take?
A standard home alarm system (6-10 sensors, 1-2 keypads, motion detectors) takes 4-6 hours. We’re usually in and out in a single day.
Can I add cameras to my alarm system?
Yes — and this is one of the best upgrades you can make. When your alarm and cameras are integrated, you get footage of exactly what triggered the alarm. We integrate both systems routinely.
Will the alarm work if someone cuts the power or internet?
Good professional systems have battery backup (continues working through power outages) and cellular backup (continues communicating even if internet is cut). We install these by default on all monitored systems.
