You'd piddle on my porch if I opened the door with lambchop and chucko greeting you...You'd be the new doggy toy if they wanted.
You're being swindled by cons with contracts...
Can your A-D-Doo alarm alert you to someone walking at 3 a.m. 200+ feet prior to the reaching the property line while you're snoozing? No it can't.
Can your acme alarm smell and alert you to a wild fire 2 miles away at 230 a.m.? No it won't.
Can your acme alarm sense danger or bad intentions before you'd ever see it or sense it? No it can't.
Can your acme alarm run into the dark on it's own and pin some spook, you never saw or heard, hiding on your property while alerting you? No it can't.
Dogs are an absolute must for home security. It's why special forces, military and cops etc., use them.
BTW, my dogs are many times more trustworthy than your neighbors and your own friends and are probably are better behaved with better manners. I know this because I know people well.
Ya they drink filtered water, salmon table scraps and home made oven baked milk bones...Best friends ever. Worth every single penny too.
There is no better sensors or security for the home other than staying awake all night with a riot gun strapped to your back in addition to perimeter LPs.
Good luck with your acme alarm Tex.
Can your dogs call you when you are away?
