Backing up Your Miniature Camera Remote Control in Case You Lose It
If your digital camera comes with a mini remote control for recording and photographing, you can make cheap remote controls for backing up in case it gets lost.
If you travel a lot or take outdoor photography, youtuber thefrugalfilmaker suggests you buy some cheap universal mini remotes that can learn all the functions of your camera’s current remote. Thus, if you leave it somewhere or throw it into the river, you will still have a fallback waiting for you. If you don’t know where to get them, he recommends this DC 3V RM-L7 Remote Control Model on eBay because it uses AAA batteries instead of button cells. For about $ 4 each, you can rest assured that your camera can always be controlled remotely.
