Not long ago, home security systems were disturbingly less than foolproof. If you forgot to arm the system or change the batteries, if the power went out (in the case of a hardwired system) or if an intruder was quick enough to disable the system before it sounded the alarm, your home was left unprotected.

Fortunately for homeowners, advances in wireless technologies, smartphones and mobile apps have changed that. Today‘s security systems are much more difficult to foil or forget about. For example, a software-supported system can send you a text message every time a door or window is opened, whether you’ve armed it or not. It can stream live video or send still images of what’s happening in your garage, living room or anywhere you’ve installed a security camera. And some systems can even alert you before a break-in — the moment a burglar pulls into the driveway.
Home security and home automation have been integrated into relatively inexpensive single platforms. Systems that would have cost thousands of dollars five or 10 years ago cost only hundreds today.
Smart security system benefits
Home security has teamed up with home automation so the same interactive service can make your house look occupied at all times. The system turns lights, TVs and radios on and off at random intervals or according to the schedule you choose. Even the blinds can be raised or lowered upon your command or according to a schedule.
The latest systems allow you to monitor your home’s security and safety — you can even watch your kids as they return from school — and control many functions with a smartphone.
Home security systems can also alert you about other hazards, including fires, elevated carbon monoxide levels and power outages, or if someone is tampering with a safe, a locked tool chest or a medicine or gun cabinet. You can use the systems to check on a child returning home from school (by arranging for a no-activity alert shortly after the child is due home). Or if you lose sleep wondering when the water heater is going to flood your basement, you can use a security system to alert you if there’s a leak.
Carbon monoxide detectors are required by code in many communities, and now they can also report dangerous CO levels to your security companies monitoring system.
Interactive systems offer other benefits as well. Prefer not to hand out keys to housekeepers or other service providers? You can unlock a door for them from wherever you are, whether you’re at work, on a trip or simply taking a walk. You can also program your home’s temperature so you don’t waste energy on unnecessary heating or cooling. During cool seasons, these systems can automatically lower settings when you’re sleeping or away and raise them again when awake and at home. Or if you’re driving home from a trip and want to cool off the house before you arrive, just pull out your smartphone and send the command.
Kwikset’s SmartCode deadbolts can be locked or unlocked remotely using wireless security software and a smartphone. You can also operate the lock with the keypad or with a key.
Buying a smart security system
Smart systems’ hardware hasn’t changed much in appearance in 25 years. There are some new specialized sensors and video cameras, and window and door contact switches have shrunk, but the basics are the same: a control panel or console, magnetic contact switches, motion sensors and a siren. Like many old-style systems, the new models also connect to central monitoring stations. The big difference is the degree of interactivity. New software platforms allow you to send commands, program home systems, view surveillance video and receive alerts on a smartphone or computer -- whether you’re at home or away.
When shopping for a system, review software platforms first. The two biggest are Alarm.com (which has partnered with more than 2,500 dealers) and iControl (partnered with ADT and Comcast). Read the user reviews before you sign the contract.
You’ll have to decide on a cellular-primary or a broadband-primary system. A cellular-primary system connects to the monitoring station wirelessly, so it’s not affected by a power outage or if someone cuts a cable. However, it is limited in transmitting large quantities of video, so many cellular-primary systems incorporate broadband for video. Broadband-primary systems, on the other hand, have cables running down the side of a house, and those cables can be cut to disable the system. Some services offer cellular backup in case this occurs.
Choose a reputable dealer that will sell you the equipment and a monitoring plan. Many dealers will also install the system for you, but some dealers sell equipment and services to DIYers. For example, FrontPoint Security, a national provider based in Virginia, sells the Simon XT, a GE-brand system that homeowners can easily install; the company also offers Alarm.com features and a third-party monitoring plan. Installing the system yourself can save you several hundred dollars — and make you more knowledgeable about how it works.
Several smart security systems offer add-on touch-screen controllers. This model from Interlogix
features two-way communication so you can talk with personnel at the
monitoring station in an emergency. It will also tell you current
weather conditions and allow you to program your thermostat.
Smart systems do not restrict the type of security hardware you can use, although a dealer may limit your choices. The inside-the-house components may be hardwired or connect wirelessly via radio frequency (RF radiation). Though hardwired components are considered the standard because they are more difficult to disable and don’t rely on batteries for power, the reliability gap has narrowed (or even disappeared) with new technology. Alarm.com and its partners offer “smash-and-bash” protection for wireless systems: As soon as a point of entry is breached, the central monitoring station is sent a pending alarm signal — it doesn’t wait to find out if the person who entered is you or a bad guy. If the system is not disarmed within the programmed amount of time, the alarm is treated as an intrusion. So a smashed controller won’t stop the central station from calling the police.
A conventional system, on the other hand, does not send a signal for a period of time (typically 30 seconds while it allows the homeowner to enter a code and then more time for the dialer to call the monitoring station). For a smart burglar, that can be long enough to disable the security system or to grab some valuables and run.
Wireless hardware is much easier to install than wired components, making it more appealing to DIYers. It can also be taken with you if you move. If you’re in the market for a wireless system, keep these tips in mind:
• Consider all of the available wireless peripherals, including modules for controlling lights and appliances, thermostats, cameras, motion sensors (some can distinguish between a pet and a person), water sensors and glass-breaking and vibration sensors.
• Seek out long-life battery power. Lithium-sensor batteries can last three to five years. When they do run low, the system lets you know well before they’re totally depleted.
• Look for a controller with a backup battery so your system will stay active if the power or Internet is out. If you plan to install smoke alarms, you’ll need a 24-hour battery backup rather than the four-hour backup offered by many manufacturers.
• All smart systems require a subscription to a third-party alarm-monitoring service. Ask about which central station will be handling your account, and be sure that it is UL certified.
A Wireless Motion Alert from Chamberlain lets you know before an intruder reaches your front door. You can install as many as eight sensors for total perimeter coverage.
Security equipment and monitoring costs
There are two costs to keep in mind when shopping for a security system. The first is for the equipment and installation (if you’re having it professionally installed). This can run from a few hundred dollars for a basic system (or less that half of that if you install it yourself) to more than $1,000 for a full-feature system with specialized sensors and wireless smoke and carbon-monoxide detectors. The second cost is the monthly service charge that includes fees for software-driven features and central station monitoring. It typically ranges from $35 to $60 a month. Some dealers, much like mobile phone and cable TV companies, will reduce the installation cost in return for a multiyear contract.
