Whether or not you're safer with a gun in the home is controversial and heavily written about, the risks of being shot by your gun vs the likelihood of you shooting a would-be-attacker. I don't have an opinion on the subject as I'm not prepared to wade into the literature, but it seems like this tech would avoid the chance of the former while still giving you the chance at the latter.
I'm not disagreeing with your post, quite the opposite. I just want to point out that the Kellerman study (which you allude to) that claimed a gun was 2.7 times more likely to be used against a resident of the house than against a non resident was horribly flawed.
The claim of the paper was that people who have a firearm in the home are more likely to die from their own guns. Don Kates proved that most of the victims in the study were shot by guns from outside the home, which makes the presence of the homeowner's gun independent of the death.
Kellerman also "proved" X -> Y, using data that actually proves Y -> X, by introducing a selection bias. Most of the victims in the study regularly engaged in criminal behavior. Criminals have a much higher probability of meeting a violent death, so murder victims are predominantly criminals, or their friends, family, or other associates. Criminals are also more likely to have guns in the home (which is strange given that it's illegal...).
What the study actually showed was a high correlation between being a murder victim and having a gun in the home. It did not sample gun owning households at random and determine how many suffered a shooting with a gun from that household.
