An apparatus, such as a network device, may include a housing. The housing may include one or more side walls that define a top rim of the housing. The housing may include a top wall. The top wall may be positioned vertically below the top rim. The top wall may have a concave or other shape and include a plurality of apertures configured to provide airflow from the interior of the housing to the exterior even when objects are placed on top of the housing.

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.
