Make sure you have a crucifix on your doors.. and pray a house consecration novena.. Praying for the protection of your house and household daily is important to do!
Sometimes burglars come back to places that they think are easy marks. Be aware. If you want the police to jail them later on and them to be prosecuted.. you'll very probably need to have a game cam/lowlight camera covering the spot they like to visit so there is actual evidence to use against them.
If the camera is concealed it's more likely to record a burglar and not be disabled by the burglar.
Kyrie eleison! My condolences on the burglary. I know it feels awful!
I bought a security system a bit back. Sitting in a drawer, haven't installed it yet. I wasn't burgled recently so haven't felt too rushed. Put the security stickers I bought up already on the doors though. I got it for protection of persons rather than belongings.
It's advertised as 'wireless' they all tend to be these days, but accepts wired connections too. Since I don't like changing batteries all the time wired is the way to go for me, and I bought a separate pack of security wire and wired sensors for it.
Since I will just wire the first floor, at least at first, I can run all my wiring straight down through to the basement and that's all open so easy to wire. I have some fish tape to help as needed.
System came with the panel, a horn, some wireless remotes, resistors (helpful for the wired parts, read up on that if you DIY), wireless sensors and a motion detector, and some not so great but usable instructions for $55, and then I got the extra sensors and wire for I forget how much. Cheapest bargain basement type system.
Seems it's able to send SMS messages somehow I'm not too clear on it, don't have the instructions handy at the moment.. until I find them again it won't get installed that's for sure. Anyway, mentioning my bargain basement system is just to give an idea. Not saying I recommend going that route.
Seems like a bit of a pain in the neck project to DIY having to test out the alarm over and over again, and the connections, but that's the price of saving money by DIY -- time and effort. Sometimes it's worth it sometimes it isn't.
Pray all goes well for you!
