Abstract: An apparatus, such as a doorbell, may include a doorbell housing. The doorbell housing may include a front surface facing exterior of a premises and a rear surface facing interior of the premises. A camera, doorbell activator, motion sensor, and/or light source may be at least partially positioned within the doorbell housing. An antenna may be positioned within the doorbell housing. The antenna may be configured to send a wireless signal comprising data to a data receiving device inside the premises. A reflective member may be positioned within the doorbell housing and configured to reflect at least a portion of the wireless signal that is sent toward the front surface of the doorbell housing.

Abstract: Disclosures relate to a sensor system and arrangements having different sized removable spacers. The spacers may be mixed and matched as needed or desired to compensate for misalignment conditions. Further, different spacer combinations and adjustments may be guided by a security management computing device. Variations in configurations of mounting surfaces, such as door and window assemblies, may be accommodated. Alignment of a transmitter or a receiving device, e.g., a magnetic device, with respect to a transmitter or receiving device despite misalignment of the components due to, for example, uneven surfaces of a door or a window, or a respective frame may be achieved.
