Gear Review: SJ4000 Action Camera


(affiliate links included)


I love to film my airsoft games.  Video allows me to analyze my mistakes, watch my victories, and share them with you.  The difficult part of filming airsoft is that the environment is not exactly suitable for a standard point-and-shoot camera.  I went on the hunt for a camera that was rugged enough to withstand my airsofting and would have the ability to film high quality footage for my readers.  After looking around and getting suggestions from my fellow airsofter, the Chief, I decided on the SJ4000 action camera.  After a half-year of use, I am sharing my thoughts on the SJ4000 so you can decide if it’s a good option for you.


The SJ4000 action camera has many features that make it suitable for hard core airsoft filming but still accessible to the weekend airsofter on a tight budget.  I’ll start with the stats on it and what comes in the box.

Accessories in the package:

I recommend watching THIS video for info on the mounts and accessories in the package.  I found it very helpful when I was researching the SJ4000.  (Note:  Extra cases can be a bit difficult to find.  HERE is a link to some on  It will also accept many of the standard mounting accessories available on the market.

A good thing to note is that the camera comes with the proper power adapter for your region.  I also recommend buying the SJ4000 desktop charger so you can charge the camera’s batteries without having the camera stuck to the wall.


How I Use It

I set mine up on my Lancer Tactical FAST Helmet so I can film footage that would be as close to my Point Of View (POV) as possible while still being stable.  I used an NVG mount (not included) to fit into the mount on the front of my helmet and used a “J” or Hook mount (included) and a small, straight mount (included) to get the camera to the angle I wanted.  I used sandpaper to rough up the joints on the mounts so they would hold better and keep the camera in position during a game.  See images 1 and 2 to view the parts used and how to assemble them.  Image 3 shows the camera mounted to my helmet.

You will note that I mounted the camera upside down to get it even closer to my POV and to avoid the “giant” effect that can occur if you mount the camera higher then your actual height.  I turned on the “Rotate” feature in the camera’s settings to make all my videos upright without editing.  You could also buy a head strap if you don’t have a helmet.  Just be sure that you get the camera angled right and keep it stabilized.



The SJ4000 is an amazing camera for the price.  It has all the features you need to film awesome footage of your airsoft battles.  It even has many of the features of more expensive action cameras.  I’ve dropped the case and gotten shot in the face and helmet and it has held up fine.   The included mounts are almost worth the price of the whole package, and they get you up and running right off the bat.  I love the fact that if it does break, it is cheap and easy to replace.

To check out some of the footage I’ve filmed with it, check out the Airsoft Warrior YouTube Channel.



As to be expected, the low price also comes at a cost of quality.  The SJ4000 can’t film in the extreme frame rates of higher quality cameras (therefore, it may have some blur when you’re moving fast).  It doesn’t have a touch screen or a fancy name either.

The only thing I’ve had malfunction in the 6 months I’ve been using it is the down button for selecting options in the menu has partially stopped working (it’s spring has gone out so you have to open the case and remove the camera to depress the button far enough to activate it.  So, technically, it still “works”.).   This seems to be a design flaw.


All in all, the SJ4000 is an excellent camera for an airsofter who doesn’t want to break the bank, but still requires high quality footage.  I highly recommend it.  Let me know what your favorite budget action camera is, as well as filming suggestions in the comments!

  1. Hey there TAW, great article!

    I too have the SJ and have put it through a beating over the last four months. You know as well as anyone else when I use something it had better be built well because I will find a way to beat it on the field.

    My SJ has worked without any problems thus so far, and the footage is very good for what you have. BEAR has a GoPro and in all honesty after comparison the SJ holds its own pretty well.

    To those thinking about getting a camera and don’t have a large budget, the SJ is the way to go!

    Thanks for all your info TAW, always looking forward to the next article!

  2. Very nice camera! I will probably consider getting one as soon as I can get some gear upgrades.

  3. Hey I was wondering what kind of sight you use? I also want to know your opinion on which red dot sight is the best?

    • Scroll,

      Thank you for your comment!

      I use the the Sightmark Sure Shot Reflex Dot Sight. It has a 3 MOA red dot, 4 reticle options, 7 brightness settings (I find the 2 or 3 is a good setting for indoor game play), and an aluminum body. I really like that it increases my target acquisition time in battle and makes shooting off hand a whole lot easier. Retail price is about $50.

      I also use a lens protector (I replaced the standard acrylic shield with a homemade Lexan one). It is an easy way to keep my optics safe on the field.

    • Scroll,

      There are a lot of similar sights to the Sightmark Sure Shot that are less expensive (like the Field Sport Red and Green Dot, which has 4 reticle options and a both red and green color options) . As with a lot of things, you get what you pay for. The quality may be lacking in cheaper models.

      I prefer the “open” style rather than the “tube” style red dots because you have a wider field of view and have better overall awareness on the field. I also like my sights to “co-witness” (both the red dot and the front iron sight line up). This allows me to use my regular sights if the battery dies on the red dot.

  4. Thanks.Is there a pretty good one for a lesser amount?

  5. Hi there.

    Is this the Sj4000 sjcam or the nock off?

    • Thank you for your comment, Quint! I believe that I bought the real SJ4000. SJCAM now places their logo on the front (which mine lacks), making it easier to tell which ones are genuine. Several differences can easily be noticed between the genuine ones and the fakes (fake version has a much more rounded case, bigger lock on the top of the case, etc.). I bought mine from a retailer on Amazon, but if you want to be sure to get the real deal buy it through the SJCAM website or SJCAM Amazon store.

      If you have any other questions, feel free to contact me through the comments or the “Contact Me” page under the “About The Airsoft Warrior” tab!
