Currently, home using Caddx alarm system (installed in 1996). The system uses numberpads, and at one time can be configured to call owners outside with dedicated phone number. That has been removed. No app/wiifi function. Just standard beep codes. Never used it. There was an option to disable/enable by calling, used few times and forgot how to set it up.

Currently home undergoing renovations, and contractors have damaged most of the alarm wiring system. As most of the wires and sensors are 90s or changed once, I don't think this alarm is sustainable into the future. Changed the motherboard with some generic motherboard since no parts. Usually change battery every 5 years. The battery act as an UPS when blackouts occur (which is rarely nowdays).

Current alarm setting:
3 Door sensor
2 sliding window door
9 Vibration sensor for windows
1 IR roof sensor (no longer required now with new roof material).
3 alarm keypads
2 alarm buzzers(1 outdoor, 1 indoor)
2 auto light-on when buzzing. Indoor and outdoor.

Can anyone recommend alarm system? Is a wired solution better or a DIY kit purchse from shoppee/lazada ok?
