A surveillance system is provided including an Internet-enabled (IP) camera and nodes that determine the location of a plurality of sensors, which are wirelessly connected to the IP camera. The nodes determine the position of the plurality of sensors and the IP camera through the use of position determining techniques including multilateration, trilateration, and triangulation. Additionally, line of sight positioning methods and global positioning system devices may be used in setting up a positional awareness system, which enables the IP camera to control systems based on condition information and positional awareness.

Integrated camera awareness and wireless sensor system

An inter-digital capacitive sensor and control system are used to distinguish between rain, ice, dirt and debris on the outer lens surface of a surveillance camera. The electrodes of the capacitive sensor are made from a conductive coating such as printed epoxy or a transparent conductive oxide, that is directly deposited onto the inner surface of the lens. A defroster is spaced radially-outward from the capacitive sensor and is formed by metal deposition directly on the substrate surface.

Capacitive moisture sensor system for a surveillance camera

A cleaning method for a surveillance camera uses a capacitive sensor to determine whether rain, ice, dirt, debris or other foreign objects are present on the camera lens substrate. A determination is made whether the sensed capacitance is greater than a first threshold indicative of the presence of a foreign object on the lens. If a foreign object is indicated, the lens is sprayed with a sprayer and then a wiper is activated. If a foreign object is not indicated, a determination is made whether ice is present by comparing the sensed capacitance to a second threshold that is less than the first threshold. If ice is present, wiper and lens defrosters are activated, and a wiper is then turned on. The cleaning method may include a temperature sensor and power management for the defrosters.
