The security insert enclosure configured to be deployed in a battery compartment.

Devices, assemblies, and associated methods are provided for mobile devices. An example mobile device includes a body defining a first surface, a second surface opposite the first surface, and a cavity at the second surface that receives a battery therein. The mobile device includes a locking mechanism coupled with the cavity of the body that moves between an unlocked position and a locked position at which the locking mechanism secures the battery within the cavity in an instance in which the battery is received by the cavity. The cavity and the locking mechanism are configured to prevent a contact between the battery and the locking mechanism that results in movement of the locking mechanism from the locked position to the unlocked position.

A portable electronic device includes a housing, a sensor array including a first camera module having a first field of view, a second camera module having a second field of view different from the first field of view, and a light source, and a rear cover formed from a glass material and defining a raised sensor array region positioned over the sensor array. The raised sensor array region defines a first hole extending through the rear cover and positioned proximate a first corner region of the raised sensor array region, and a second hole extending through the rear cover and positioned proximate a second corner region diagonal from the first corner region. The first camera module includes a first camera housing defining a recess at a corner of the first camera housing, and the second camera module includes a second camera housing extending into the recess.

System and methods for adapting a smart phone for use as a hybrid smart phone and smart camera, referred to as a modified or hybrid device. The modified device is based on a set of smart phone components which has its battery removed and is instead powered by alternative circuitry. The modified device is also outfitted with a variety of modifications which allow it to operate in an extended temperature range. The modified device is loaded with software and circuitry which allow it to operate automatically without human interaction. The modified device functions as a smart camera but includes beneficial smart phone functions and features.
