Common questions
Are alarm installers licensed in Texas?
Yes. Texas DPS regulates alarm companies and installers under Chapter 1702. Ask for the company license and individual registration before work starts.
Can I keep my existing alarm equipment?
Sometimes. The installer checks the panel, communicator, sensors, and whether the system is locked to another provider. Some old panels are better replaced.
Do cameras need wiring?
Wired cameras are more reliable, but wireless can work when signal and power are solid. The installer checks Wi-Fi, walls, attic access, and where recordings will be stored.
Can you secure a vacation rental?
Yes. Smart locks, exterior cameras, noise or occupancy monitoring where allowed, flood sensors, and owner access logs are common for Padre Island rentals.
What causes false alarms?
Loose contacts, weak batteries, bad sensor placement, pets, doors that do not latch, and user error are common. A service visit should test each zone.
Do I need monitoring?
Monitoring is useful when you want dispatch or alerts handled even if you miss a phone notification. Self-monitoring is cheaper but puts the response burden on you.
Can you install smart locks?
Yes, but door fit matters. If the deadbolt drags or the frame is out of square, the smart lock will burn batteries and fail. Fix the door first.
How long does alarm installation take?
A typical wireless alarm install is done in a few hours. Whole-home wired systems, or setups with several cameras, can take a full day. The installer can usually give you a time window before the visit.
Can I get an alarm installed in a rental home?
Yes, renter-friendly wireless systems are common. They mount without permanent wiring and move with you. Check your lease first, and ask the installer for no-drill options if your landlord requires it.
