Wired Alarms
Hard wired alarm panels and devices are typically cheaper to buy compared to wireless, but there's also the additional cost of the cable, cable clips, trunking etc. Wired systems are usually more expensive in a domestic property due to the complexities and time involved routing and hiding the alarm cables.
Since the devices in a hard wired alarm system do not run on batteries there's no battery replacement cost there. However the back-up battery in main control panel and the external siren battery will require changing approximately every 3-5 years, just like wireless.
