Abstract: A cylindrical secondary battery module includes: a plurality of cylindrical secondary battery cells respectively having a battery case in which an electrode assembly and an electrolyte are accommodated; a cell frame at which the plurality of cylindrical secondary battery cells are disposed; and a lid coupled to the cell frame and having a flame outlet. The cell frame includes: a plurality of plate members bent and coupled to intersect each other; and a space formed between the plurality of plate members so that the cylindrical secondary battery cells are disposed therein.

Abstract: A method of setting spatial information for defining a space in the shape of dimensional data or property information including relationship information between objects installed in the space is defined, and a video monitoring apparatus is set to be linked to the defined method. Then, based on the same, a video captured by a video monitoring apparatus provided in a space may be efficiently output on the web. Therefore, various functions may be performed in which 3-dimensional spatial information and video monitoring are linked in a very easy way.
