Action cameras are a form of small, lightweight, mountable, portable, wearable, and sometimes waterproof camcorders. They're befitting as they can be mounted on pretty much anything—from bicycles, drones, skateboards, surfboards, to helmets, body parts, and even a pet.
Sure, you can also mount a conventional camcorder, which could quite often feature enhanced functionality and performance for the price. However conventional camcorders are too heavy and cumbersome to strap onto body, your apparel, or your equipment. Additionally, the gap between typical camcorders and action camera performance is lessening as technology improves. Action cams are forever becoming smaller, lighter, and less expensive.

A camcorder (video camera recorder) is a portable electronic recording device with the ability to record live-motion video and audio for playing back at a later time. Camcorders feature three major components -- a lens that acquires and focuses light, an imager that reformats light into an electronic signal and a recorder that converts those electrical signals into digital recordings and ciphers them for storage.
Camcorders, which became trendy in the early 1980s, are also called video cameras or video recorders. Professional videographers and filmmakers make use of camcorders to create video segments and films for commercial marketing. The devices are also favored by amateur videographers.
The first camcorders captured video in one of two analog formats, VHS or Betamax formats. Recordings were stored on video casette tapes and replayed using a video tape cassette recorder (VCR) connected to a monitor, most often a TV set. As technology developed, additional formats like 8mm, S-VHS, Hi-8, digital video (DV) along with high definition video (HDV) became available. These formats provided a sharper picture, better color, additional hours of recording time and more efficient storage.
Today, camcorders capture video in an array of formats, including MP4. Most camcorders may be directly connected to a personal computer using a Universal Serial Bus (USB) allowing the video to be edited.
Just about all are Flash Memory using digital formats
Secure Digital the amount of standard-definition video you can capture at the highest quality level can range from 15 minutes to an hour on 256 MB to 2 GB memory cards.
However, the original SD memory card, which can only store up to 2GB, has all but become obsolete and superseded by SDHC and SDXC memory cards. Therefore, it will probably be both easier and more economical to purchase an SDHC card, over an SD card, provided the camcorder is SDHC compatible.
A general rule of thumb is that the higher the video quality the larger the storage capacity of the card required. For a camcorder capturing standard-definition footage, it is usually enough to use one of the lower capacity SDHC cards such as 4 GB or 8 GB. However, if the camcorder can shoot in high-definition, the memory card should ideally be 16 GB or even 32 GB. If the camcorder supports SDXC format, your best choice may be a 64 GB or 128 GB card. SDXC cards have a theoretical 2 TB capacity, but at the time of this writing, the maximum capacity readily available is 128 GB.
