Meh.  All that does is shoot blindly when it detects a heat source.

A better mod would be to make it an actual Sentry Gun that tracks targets and fires at them, like this :

Think of the implications for this, btw:  A truly paranoid person could build up several of the paintball/airsoft sentry gun using real guns.  It would be relatively simple to build them, the technology is there for a reasonably handy person to build them, and you could armor them well enough that they would be resistant to small arms fire typical of that carried by law enforcement.

Because of the nature of electro-mechanically actuating the trigger, you could also turn what is a legal semi-automatic firearm into the functional equivalent of a machine gun, limited only by the actual time it takes the action to cycle.  With semi-auto firearms, the rate of fire is limited by how fast the individual shooting can pull the trigger, and to get a cyclic rate of 600 RPM, you'd have to press the trigger 10 times in a second.  Fastest shooter in the World, Jerry Miculek, can only do about 526 RPM (for 5 shots).

But even the project in TFA has domestic security implications:  How hard would it be to wire up concealed pipe-bombs, or even just hidden single-shot improvised shotguns, around your compound that are actuated by infrared sensors?  Child's play, just like wiring up a light.  Have a remote activation switch so you only turn it on when you hear the black helicopters circling.  Arrange the geometry of the detector so that the only way it can be detected by remote sensing is if you are in the activation area of the detector (ie., behind an obstruction that channels movement or around a corner), so that the ebil gubbmint stormtroopers won't know about it until it's too late.

You could make a very formidable defense using something like that.  Consider what might have happened if Osama bin Laden had something like that at his compound:  AK-based sentry guns and IR booby-traps activated by a "panic switch" in his bedroom.  Navy SEALs enter the compound, and because he knows the jig is up from the noise of helicopters and shooting, he hits the button.  SEALs can't advance through the hallways because every time they do, they are shot at by machines or they activate some booby-trap that kills one or more of them.  Makes it a much harder nut to crack, and it's possible (though unlikely) that in the confusion post-attack that bin Laden escapes.

It is indeed going to be a Brave New World that we live in.  At least, it had better be.

Important Note:  I'm not advocating doing any of these things, because that would be a violation of the law, and morally setting up automated lethal traps is reprehensible.  This is just a gedankenexperiment about the security implications of technology like that.

When I was working at Fujitsu -we had all toy guns banned in the building after the CEO got hit inadvertently as senior Programmers were in a foam dart war with their managers.

I've got a couple sensors that would work for this.

We already use the damn things to identify and track targets as it is, but the sensor is stationary.

This is all on paper, of course.

It's lots of fun, my boss just shakes his head. Pretty good range on it too.
Wish I could automate it.

They can have my foam-darts when they pry them from my lightly bruised fingers.

I noticed that, too. It's still cool and fun, but I don't think it would be worth the effort to have it only fire blindly.

Listen, we're all in strung-out shape, but stay frosty. We can't afford to let even one of those things in here.

You know, I have an old Bondwell B310+ laptop, the same kind used for the sentry gun controllers in that movie.  Except mine has the LCD screen, not the neat plasma screen.  But still, it's kind of cool in a geeky sort of way.  I ripped out the 40 MB drive, put in an 80 MB, and loaded it with Minix.  Every couple of years, I haul it out, boot it up, and play with it for a little while until I get bored, then I put it away again.

Looks like sumpthing a cam girl had in her room; hooked up to your tipping her some coinage... Cool in and out action. Or so I overheard at the gym locker room; yeah, overheard... Not that I would tip all my rent $$$.

It wouldn't be very difficult with an Arduino, some IR sensors and a couple of servos.

I was looking at all the parts I have here and was daydreaming about making a drone.  Then I realized it wouldn't be hard at all to make an RC/Autonomous drone.  Take off RC, flip a switch for the processor to take over, and use GPS and inertial sensors to fly a pre-programmed pattern.

Until I saw it's very illegal and I don't want it getting sucked into a bizjet engine and killing everyone on board.

Fly it low and program a course to avoid airports.
