Q&A
[1]
- Electronic locks generally cost
between $70 - $400 [2].
- Normal locks do not have
forced entry detection [2].
- The only locks that allow
remote unlock are the more
expensive versions [3][4].
- Other electronic locks do not
have the ability for the user to
see what phone was used to
unlock the system [2].
[3]
[4]
Proposed Features:
- Reasonable pricing at
mid-market value,
approximately $200
- Forced entry detection
feature notifies the
owner upon attempt
- Door entry information:
Number of entries,
Phone used to unlock,
etc.
The system is wired directly into the customer’s electrical system and is
therefore as reliable as the power supply. In case of power outage, the system
can be powered from the backup power supply for a 24 hour period.
[5]
The system will notify the homeowner via SMS if a forced entry is
attempted. The user will also be able to secure area with cell phone
via SMS.

Description
The device must be able to communicate with the user via Short
Message Service (SMS), allowing the user to lock/unlock and to
notify the user if the door has been locked or unlocked.
The Smart Lock Security system must be powered by a 120VAC
source. A backup battery with a current range of up to 3A is
required to power the device in the case of a power outage.
The device must provide an additional method of access and system
configuration at the physical location of the device.
The LCD screen must display the correct information to the user.
Some of the required information will be a menu with multiple
options and further instructions based on user’s decisions.
The device must be able to detect unauthorized entry when the
solenoid is in the lock position.
