SJCAM SJ4000 action camera: equipment
The device kit includes various mounting mechanisms made of durable and reliable plastic. These parts can be combined with each other, getting the necessary fastening. How to connect them is described in the instructions.
Also included is a steel cable for insurance that can withstand much more weight than the weight of the camera. In the package you can find double-sided tape for mounting the device on a fixed surface. However, it can peel off in the sun, so you should always be safe with a cable.
Airtight chamber
SJ4000 action cameras are equipped with a special aquablock, durable and reliable. It snaps firmly so that water cannot get inside. In addition, in a waterproof container there are chambers filled with air. This is done so that the camera could not drown if it falls off the mount during underwater shooting.
An additional back cover with openings on the sides goes to the aquablock. It is designed to enhance microphone performance in wet or dirty conditions when the camera is not used underwater.
Sound
The SJ4000 action camera, reviews of most users emphasize this, has a good sound: from almost five meters you can hear almost every word. Although some people are not satisfied with the sound quality. This, most likely, depends on environmental noise and build quality of a particular model. The recording here is accompanied by a superimposed music track, without the sounds of nature and ambient noise.
