Security: Become Master of All You Survey

You install software updates to keep your Mac and iPhone secure. Let them return the favor by keeping tabs on your home while you're away.
Keep an iSight on Things
Mac has a built-in iSight--or almost any QuickTime-compatible camera attached--you’re one step away from a surveillance system. All you need is software like Security Spy ($50) or EvoCam ($30), and you’re in the counterespionage business.
Each application records pictures and video to your Mac continuously, according to schedules you define, or when it detects motion in a camera’s field of view. Just launch the app, point your iSight where you expect snoops to sneak (like a doorway or maybe the desk holding your plans for world domination), then leave your computer running. When the camera picks up movement, the software can start recording, email you a photo of the suspicious event, or alert the Mac running your home automation system to trigger a larger security plan. If you’re more curious than concerned, both applications can upload pictures to an FTP site and serve video to the internet, letting you view your camera’s feed from a browser. You can even log in remotely and tweak your security camera’s settings.

EvoCam's surveillance system indulges your counterespionage fantasies.
An iSight or webcam is fine for a small room, but Security Spy and EvoCam can monitor and control multiple video sources simultaneously. If your need to know extends to several rooms or even outdoors, you’ll want to weave a larger web of spies... er, cameras.
Expand Your Horizons
Stepping up from a single-camera system doesn’t have to be difficult. The same software and principles apply; you’ll just add additional cameras, video servers, or network cameras to view and control it all from a central Mac.
Video servers send footage from multiple cameras to your wired or wireless network. If your cameras are digital, other Macs running surveillance software can do the job of the server. But if you’re using analog cameras like Q-See’s night-vision-capable QSC48030 ($199.99), you’ll want a dedicated server like Axis’ 240Q ($499.99) to digitize the signals so they can be seen by your Mac.

Network cameras have built-in web servers that can join networks without the need for extra gear. A wide range of network cameras is available for every budget, from Panasonic’s webcam-style, 802.11g-enabled BL-C131A ($299.95) to the Axis 214 PTZ ($1299.00), which wouldn’t look out of place in a villain’s lair (or on a department-store ceiling). These and many other network cameras also sport lenses that can remotely pan, tilt, or zoom in to give you a better view of the action.
There are endless varieties of hardware to consider, but the good news is there’s plenty of gear out there to fit your needs. Both Security Spy and EvoCam’s sites offer lists of compatible equipment that make good starting points for building a home-surveillance network.
Sensor Yourself
Handy as video surveillance is, it probably won’t be a good fit for every room in your house. For places where cameras are impractical, obtrusive, or just plain weird, Insteon motion sensors and magnetic door switches can keep tabs on who goes there when you’ve gone out.
SmartLabs Design’s battery-powered Wireless Motion/Occupancy Sensor ($34.99) installs almost anywhere to detect motion in a 110-degree arc at a range of 40 feet. When an intruder is discovered, the Mac running your Insteon system can send you an email, turn on lights, or release the hounds. Because these motion detectors work by sensing heat, you’ll want to install yours in places without extreme fluctuations in temperature. That includes areas near heating grates, fireplaces, or large windows that get lots of sun.

SmartLabs' wireless motion sensor alerts you to intruders.
If motion detectors won’t do the job, guard your perimeter with SmartLabs’ TriggerLinc Wireless Open/Close Sensor ($34.99). Half the sensor attaches to a door, and the other half installs beside it on the door frame. Opening the door breaks the magnetic contact between the halves, letting your network know a would-be 007 has entered the room or found the hidden compartment in your desk. Since the TriggerLinc is compact and wireless, it installs on just about anything that opens: windows, drawers, server closets, you name it. You’ll never wonder if the babysitter has raided your liquor cabinet again.
Unlock the Possibilities
Security isn’t just about keeping people out. It’s also about letting the right people in, and the internet can help. The web lets you access secure information... why can’t it open your front door? For a monthly fee of $12.99, that’s just what Schlage’s LiNK Starter Kit ($299) can do. Its lever lock (also available in a dead bolt model) replaces the one already installed in your door, and ten buttons above its traditional keyhole allow entry with a programmable access code. But the lock also sports a battery-powered transmitter that talks to the included Bridge, a base station that connects to the internet and creates a wireless network for other LiNK devices, like the lamp controller that rounds out the kit.

Schlange's LiNK Starter Kit remotely opens your front door.
Once you’re a LiNK subscriber, you can log in to Schlage’s site and control your lock from anywhere. Need a friend to check your house while you’re away? No problem--remotely program your lock with a custom access code. The in-laws arrived while you’re stuck at work? Just open the door for ’em (or don’t, we won’t judge). You can even use the free Schlage LiNK iPhone app to manage access while you’re on the go. If you’re worried about being locked out when the internet is down, Schlage claims its locks’ batteries will last up to three years... but keeping a spare key on hand never hurt anybody.
Put Professional Security a Touch Away
Schlage’s LiNK is one of several commercial packages that combine home security, automation, and the iPhone to monitor and control your home without fuss. Even if you’re not the DIY type, you can bring your peace of mind into this century.
Commercial security companies offer plans and products designed to work together seamlessly. Products can include motion detectors, cameras, and other sensors run from a central control panel on a wall instead of your computer. While the basic idea is the same as a home-built system--devices monitor your house and warn you in case of trouble--commercial systems can offer integrated fire detection and alerts to personnel who will contact the authorities in an emergency. Plans cost anywhere from $30 to $50 a month (plus installation fees), but their features and simplicity may be worth the expense.

For a monthly fee, commercial security companies can provide more than peace of mind.
Alarm.com, CPI Security Systems, and Platinum Protection each offer free applications that let iPhone users control their security systems. These apps let you arm and disarm your system, monitor camera feeds, receive notifications when sensors detect something, and view a history of recent security events. Want to know what time your teenager really got home from his friend’s house? There’s an app for that.
