We live in a small condo building 2 bedroom apartment. On our rear entry and exit door from the kitchen . Someone is leaving food at the at the door mat . A month ago a half size bagel was hidden under the door mat . Today when we went our in the afternoon for two hours and came back we found a small bagel that is left intentionally . We are on second floor and the condo is a small 3 floor building. Mixed race people live and different sex. We are Asian American . Please see the pictures are below. We have no enemy in this small building We haven’t had any trouble with anyone. We are a parent and a small special needs child . I can’t understand why anyone would do this intentionally to us. Making us feel bit nervous. Of course the condo association won’t allow us to install any cameras or anything upside the door or walls. Need something I can stick or hang on the small window that is on the door and attach it there so it can record whoever is going up or down or coming towards our door. Please see the pictures and suggest an affordable mini camera with WiFi and our SD card. Thank you
