"We experienced beeping coming from our key pads on our ADT system. Certain zones were reported to check. We replaced batteries in the smoke detectors but that did not resolve our problem. Called Maximus Security, Kevin performed a complete system check. Found our back up battery was low on reserve power and replaced. Also rebooted system and performed certain coding that resolved our issues. All this for a very reasonable charge. What’s better, we got a call from Kevin a week later as a follow up call just to check if all was well. 5 star service!"

Home Security Systems FAQs, answered by experts

When deciding whether a home automation system is right for you, consider the advantages and disadvantages first.

Pros

  • Home automation can help make your home more energy efficient, possibly lowering utility bills.

  • A wide range of automated solutions is available to meet your needs.

  • Centralized and remote control of different home automation systems.

Cons

  • Home automation can be costly.

  • Not all automated systems are compatible with each other.

  • Over-dependence on home automation can be problematic if systems cannot connect to the cloud.

Smart deadbolts are a worthwhile investment for homeowners seeking more convenience, flexibility, and advanced features than a traditional deadbolt can provide. While a strong conventional deadbolt offers sufficient security for most, smart deadbolts provide significant upgrades.

Key benefits include keyless entry via smartphone, keypads, or biometric sensors, and the ability to lock or unlock your door remotely. You can also manage access for guests by creating temporary codes, eliminating the need for physical keys and the risk of them being lost or duplicated. Many models integrate with smart home systems and offer features like automatic locking, entry-exit monitoring, and tamper alerts with encryption for enhanced security.

However, there are downsides to consider. Smart deadbolts are more expensive than their traditional counterparts and rely on batteries and wireless networks to function. This dependency introduces potential vulnerabilities, such as hacking by skilled intruders and privacy concerns. Installation can also be more complex. Despite these drawbacks, the added layer of convenience and protection makes them a compelling option for many.

Each has its use, depending on the scenario. Security doors are primarily intended to keep people out of the home, while storm doors are used to protect the home from extreme weather. Both tend to be made from heavy-duty metal and may include glass panels to allow light to enter the home. Storm doors can feature mesh screens, just like screen doors, to allow for increased ventilation and to keep out pests. Security doors rarely, if ever, have mesh screens.

It depends on the type of sensor your home security system uses. If it’s a motion detector, any moving thing could set it off, from a roaming pet to a wind-blown curtain. Contact sensors would be triggered by the window being opened or moved. Also, be aware that any sensors placed too close to your vents could trigger false alarms whenever your heat or air conditioning is running.

False alarms happen, and they could be due to a problem you need to troubleshoot, like faulty wiring, a mistaken setting, or the system needing an update. Turn off your system by disconnecting its power supply (both the battery and transformer) and give the manufacturer a call to see what they advise.
