Hello there! Based on your question about door intruder alarm sensors, here are a few options from the PriceCheck search results that could work well: The Wireless Magnetic Sensor Window Door Entry Alarm System MC06-1 seems like a great basic option for R149. It uses magnetic sensors to detect if your doors or windows are opened and will sound an alarm. For a smarter solution, the XiaoMi Mi Window And Door Sensor 2 is excellent value at R219 - it connects via WiFi so you can arm and disarm remotely from your phone. I'd also consider the Smart Wifi Door Window Sensor Recharge for R299 if you want battery-powered sensors that are rechargeable so you won't have to regularly replace batteries. Hopefully some of these give you a good starting point for securing your doors and windows on a budget. Let me know if you need any other recommendations!
