​
filterCamaras

Filter cameras by a specific key-value pair across all camera properties. 
filterCamaras(listCams, key, value)
​

The key parameter is normalized using normalizeString() to remove accents and converted to lowercase for matching.

The function automatically revokes previously generated URLs to prevent memory leaks. Store the returned URL immediately in your download link.
