A system, apparatus and method are provided for using an imaging device for surveillance. The piezoelectric layer is composed of a compound oxide containing at least lead, zirconium, titanium, and oxygen, and the compound oxide has a perovskite crystal structure. The apparatus also has an inner sleeve disposed within the tubular conduit of the outer sleeve. Light directing elements for focusing the light emerging from the lateral surface and for deflecting the light emerging from the end face are provided such that the light emerging from the end face is directed toward a light exit surface arranged opposing the light emerging from the lateral surface. The first matched filter pair may include first and second matched filters, where the first matched filter includes a multiplier operable to multiply, on a sample-by-sample basis, a sample by a coefficient. The anisotropic conductive film composition includes an ethylene-vinyl acetate copolymer, a polyurethane resin, and organic fine particles.
