Do keep in mind that these locks can go wonky for any number of reasons, and that, if our neighbor is any indication, they have a very short (perhaps 3-5 years) life span. They just replaced their lock for the third time in nine years, each time going up a tier in apparent quality. The last one failed after a very hard freeze and being un-exercised for a week. Imagine getting home at 3:00 am and finding the lock inert. The key simply turned 360 degrees without catching and the remote did nothing even though the LED on it and on the lock responded. They had to break out a piece of glass to get the door open.
**One of my neighbours has one of these new, high tech front door locks.
Cost him 700 Bucks. Fingerprint, swipe card, cell phone compatible. I
just have a primitive key in lock system (the best I could obtain) with
a door frame strengthener). It'll do me. FWIW: I had to break into
through the front door of my in-laws home, after the old guy managed to
damage the door lock. The damage was substantial and I saw only one way
to remove the old lock. I had to cut the stainless steel bolt. I dug out
my battery angle grinder, fitted it with an innox disk and prepared for
a long job. FORTY FIVE SECONDS! That is how long it took me to cut
through the stainless steel bolt! YIKES! Burglars have it easy nowadays.
All the fancy locks are no match for an angle grinder and a suitable
cutting disk. An alarm is essential. Window bars? No problems. Locks
just keep honest people out. Further and for the record: A mate lives in
a high(ish) crime area. Fancy home, the best locks. After his home was
broken into twice in quick succession, he called me for help. I went
over immediately and fitted a siren box, with a blue strobe light and a
red LED. No break-ins since. I did, eventually, put a complete
(Professional) alarm system in his home, but the siren box, prominently
mounted does most the deterrence.

**For the most part, burglars hate motion activated lights. Yes, the
lights do give them an easier job, but it does alert others to the
intruder/s.

**ALL professional alarms are fitted with back-up batteries (my alarm
operates for about a week without mains power). Most modern
(professional) alarms operate with the cellular 'phone network. Cut
'phone lines are very much a 20th century problem.

**A large dog is not, necessarily, the best choice. It depends, of
course, but two small dogs are less easily bribed with food and make a
Hell of a racket when disturbed.
