Abstract: In some implementations, a system is capable of managing keys for encrypting media streams over UDP communications between a media source and an associated server. A key is initially generated for encrypting a media stream captured by a media source device associated with a monitoring system of a property. A first instruction is provided to the media source device and over a secure communication channel. The first instruction causes the media source device to encrypt the media stream using the key when received by the media source device. A second instruction is generated for decrypting the encrypted media stream. The second instruction is provided to a computing device associated with the property. The second instruction causes the computing device to decrypt the encrypted media stream when received by the computing device.

Abstract: A circuit for direct current (DC) offset estimation comprises a quantile value circuit and a signal processor. The quantile value circuit determines a plurality of quantile values of an input signal and includes a plurality of quantile filters. Each quantile filter includes a comparator, a level shifter, a monotonic transfer function component, and a latched integrator. The comparator compares the input signal and a quantile value. The level shifter shifts the output of the comparator. The monotonic transfer function component determines the magnitude of the shifted signal and provide a transfer function signal. The latched integrator suppresses transient characteristics of the transfer function signal and provide the quantile value. The signal processor is configured to calculate a weighted average of the quantile values to yield a DC offset estimate.

Abstract: In some implementations, techniques are described for detecting abnormal installations in a property monitored by a monitoring (e.g., security) system. For instance, an aberration engine may be used to detect an abnormal sensor or system installation within a property based on comparing detected installation data against local installation patterns of local providers within a certain proximity to the property. In some examples, the attributes (e.g., installation time, components used, number of tests performed, etc.) of a monitoring system installation, including installation of components of the monitoring system, may be compared to average installation times of other nearby installations to detect abnormalities in the installation.
