英国采购需求：安全、智能家居养老、Zigbee跌倒检测传感器、Zigbee人体感应器、Zigbee安防传感器、便利性

I'm currently exploring options for a fall detection sensor designed for elderly care, specifically one that includes presence monitoring features. I'm interested in assessing the product's performance and would like to know if you provide small quantity samples for evaluation purposes. If the evaluation goes well, we anticipate placing larger recurring orders in the range of 500 to 1000 units moving forward. I'd appreciate any information you can share about sample availability and pricing details. Looking forward to your response!
