Quoted from PW79:

Ring doorbell & Wifi cams are worthless.
It’s pretty much SOP to cut the co-ax & CAT5 outside before entry.
That takes all cloud based cams offline. BTW those have a high traffic shutdown too. So most of those will only “record” a 30-sec clip once per 5 minutes. Also motion detection on cameras is not reliable. So you get 1 minute of a 10 minute event? That’s a 90% fail IMO
IP based communication on alarms, or landline, again is terrible. Lines will be cut & a power loss renders them useless even if the alarm has backup battery since your WiFi or voip modem does not.
Glass breaks on the wall are almost always worthless. They need to be line of sight with the window & no curtains or blinds can be used. It often takes several of those in 1 room. Shock sensors on the window are the way to go.
Protect every door, every accessible window via shocks, toss in a few motions for redundancy when away, use cell based communication only, use real NVR cams & avoid smart home automation like the plague.
A real alarm + legit CCTV system will be apx $5K+ There are folks who want a “deal” and then folks who want security. Reps & techs can quickly identify who is who & if you’re perceived to be the first you will get sold a deal & not security.
Guns are good but you need an audible warning it’s time to flee or defend. Otherwise you will get smoked as the intruder has the upper hand. I’m not ready for a home invasion with taking a shit, making fried rice or playing pinball.
Plus collateral damage is real. Will you miss. Will it hit your kid or the neighbors house?
The best bet is to not come home & interupt your intruders or deal with one who snuck in when you were home. What if someone opened the window to your kids room & had no interest in the guns, money, jewelry & pills in your master suite?
A gun won’t do shit there.
Monitored CO and Smoke is a reeeeally good idea too.
Go to a professional IMO
