Currently staying at my parent's house with my toddler whilst they are away to cat sit (at their request).
Some weeks ago, their next door neighbour was broken into during the night whilst they (including young child) slept. Despite there being valuables available, the single thing that was taken was a knife left on the side in the kitchen - which tells me the intruders had intent to harm.
I tried to persuade my parents to have a security system installed that included some CCTV so that activity downstairs could be viewed from a phone, but they opted for a basic alarm system. It is currently armed and so my fear is not of whether someone could intrude without knowledge, but more so of if the alarm sounds, do I assume it's an intruder and call 999? What if it's just one of the cats? The prospect of it going off in the middle of the night and it being a false alarm, but me responding like it's legitimate is causing me enough anxiety to keep me awake.
