The SJ4000 comes in two versions. The first model named SJ4000 WIFI with built-in WIFI supporting connectivity, viewing camera through special Android / iOS mobile apps and the more basic one, SJ4000 without any mobile functionality that’s been reviewed.

That being said. The main differences between various models are expressed mostly in build quality, Accessories quality, sensor type,  functions etc.

Design & Quality

From the first impression, all items including accessories are high standard and genuine. The camera casing surfaces have a rubberized coating with Rough surfaces on the sides, making the unit durable to scratches and dirt sticking to it.

The waterproof protection casing is mostly made from transparent ABS plastic with external push spring-activated mechanical buttons, that on my personal taste are hard to press. Probably in time spring strength should weaken as the device is more used.

The product package includes many types of accessories. Clips, grips and special mounting elements, according to specific usage. For example camera, mounting unit for sports helmet or for a bicycle, special car bracket, On-body Belt clip for carrying camera etc..

Verifying  Product is  Genuine  ( SJCAM  Brand ).

Main Indicators :

  • SJCAN LOGO printed on the camera.
  • SJCAN LOGO appears when the device is turned on.
  • No English spelling mistakes on the product package.
  • Authentication QR Code label located on the right side of package As shown in the photo below.

Stills Photos :

The Camera has x4 optical zoom settings by pressing the arrow (navigation) buttons located on the right side of the camera. From my test photo quality is good, but not amazing. The shutter speed response from the moment the “OK” button is pressed is pretty fast, no complaints here.
