As said, what do you want to achieve with a camera? The chap down the road had his garage emptied a month or two back. All captured in full HD. And then? Unless the police recognise them from previous encounters or you've modelled your life on The Equalizer, not much will happen. In practice, the apprehension rate for burglary is close to zero.
Discouragement is your friend. Thieves are lazy, they'll take the paths of least resistance and minimal risk. Somewhere they can get in and out quickly, and if it will take time, somewhere they can take that time without being seen or interrupted.
I don't think having an actual alarm is worth the expense (we got rid of our ours) but having a good facsimile of an alarm is a very good discouragement (we kept the boxes and a LED). Given a choice, thieves will go for a house without one. Make the house look occupied, smart lights or dumb timers, and motorized blinds etc. It's astounding here in winter when it's dark how many houses are clearly empty. You make sure everything is reasonably secure, but that's really to reduce the wriggle room for insurers, you can have all the fancy deadbolts and locks, they'll smash a window, patio or door, or UPVC panel. The back of our house has more glass than brick. Security lights can be useful, but if it's a secluded place, you might just be giving them some light to work under. Think about how you'd break in, access routes etc. and what would stymie you. Thieves generally aren't the brightest people.
We do have five Arlo cameras. I'm happy with them. They're mostly for reassurance, bought back when we both travelled a lot. They're wireless and run on batteries – the original lithium cells lasted about six months, I got some rechargeables that last a couple of months. There's couple in the house covering entry points (all that glass), one on the garage looking back at the house and anyone trying to get into the garage itself, one on the porch and one on the side of the house looking down the driveway. The driveway cam activates the porch, so works like a Ring and we get a mugshot. They're the original models, a couple of years old now, so 720p. Close up the quality is fine, you're not going to identify a face at the bottom of the drive. Night vision is fine close-up as the IR is internal. I did wonder about the wifi as we've always had issues, but it works fine with the cameras outside the house. It's a dedicated network and seems to pump out one hell of a signal.
But again, what would we do with the footage? The same applies for a full high def wired CCTV system (we got quotes for several thousand pounds not to mention the monthly subscription, the Arlo cost about £500). You could film the miscreants in the act – in Imax quality – and obtain a DNA fingerprint, and their home address, but the might of Surrey's finest would not exactly swing into action. You'll get a crime number and many, many unhappy hours filling out insurance claims.
(and a nod to off-site computer backups, something like TV can easily be replaced, a computer full of photos, all your music etc. less so. I know several people who lost their computer and, oh, the USB drive they'd been using a backup...)
