1. A detection device, comprising:
a processor configured to:
receive, from an infrared temperature sensor, a temperature signal associated with an heat emission of at least one individual within a monitored area;
receive, from an electrostatic-charge-variation sensor, a charge-variation signal indicative of a variation of electrostatic charge associated with the at least one individual;
jointly process the temperature signal and the charge-variation signal; and
detect a presence of the at least one individual within the monitored area based on jointly processing the temperature signal and charge-variation signal.
