Most tough dogs will fight quietly but will bark/growl at strangers (especially when protecting their own turf). We also train dogs in a technique called "bark & Bite" on building searches and suspect escort/guarding.
Home Defense US: Bird Shot in a shotgun is very effective weapon as it does not generally penitrate the exterior of the house or the walls.
Spot on here. 12 gauge bird/buck shot will reduce collateral damage.
Camera's... CAMERA's... they are cheap and wireless you can place them darn near anywhere and provide you with the ability to see before you respond.
Let me preface this last statement by stating that part of my income is derived from providing clients with CCTV security solutions. The rest of my income is derived from providing electronic security (burglar alarm, access control, fire alarm, industrial control supervision, etc....) Its my bread & butter but...........................
Sometimes people are lulled into a false sense of security with electronic sensors. They will definately bring help..........eventually. During most violent home invasions/push-ins, kick-ins, the time from point of entry to contact with the intruder can be seconds. At this point, CCTV is a silent witness to the unfolding crime.
burglar alarm, CCTV etc..... is for the polite easily discouraged burglar, not the trained professional/Criminal sadist who is intent on harming you and your loved ones.
Rule #1 of force/loved one protection, layer your security with electronic long range perimeter sensors combined with physical security that prevents/slows penetration combined with multiple options to eliminate the threat.
