Eyes of Things will develop a peephole surveillance system. Before leaving home, the user will attach the EoT device to the peephole. The device will continuously monitor for presence and/or suspicious activity at the door, sending alarms and pictures via Internet (if home Wi-Fi is available). The device will not need cables, since it will function with its own rechargeable battery. Tampering detection will be also implemented (i.e. an attempt to cover the peephole) and will also generate an alarm.
