Let me say right at the start: this is a great little camera. I have heard so many good things about it and was so excited when I got the chance to get one. I thought it would be interesting to break from the norm and see if this camera, not often talked about here, could make a good dash cam. I know, I know many will say it looks like a GoPro and if I put that in my car etc. etc. I say yes, maybe you're right, yet it does so many things right.
I got this camera from Gearbest.com, who I have to say since they are a newly introduced seller, has been awesome with both super fast one week shipping and answering my many questions quickly. With all the fakes floating around, I had a lot of questions. They also have the cheapest price going for an SJ4000 at $84.99 with free shipping using code GBSJ4000.
The SJ4000 wasn't designed as a dedicated dash cam, this camera's main purpose is an action cam that the designer added dash cam features to. The question, are those features good enough? I say yes. I've been using this camera the past few weeks as my daily dash cam and it works great and hasn't disappointed. Everything you need in a dash cam is there. Things like auto start/stop, loop recording, the ability to set different clip lengths, the ability to lock files and even Motion Detection, all wrapped up in an easy to use interface. Of course, missing are dash cam specific things like G Sensors and GPS that not all users want or need. The SJ has very sharp video and the 170 degree lens gives very wide side to side coverage. I was surprised how wide this lens was.

I mounted it using an extra Mobius adhesive mount
The SJ4000 takes 4 seconds to start up and start recording and has a 5 second delay on power disconnect and power down. Video bitrate is around 15 Mbits per second on normal.
It can be used with the battery removed for those who don't like using batteries in hot cars. The only problem is you will lose the clock settings. In testing, the camera settings did remain without the battery, only the clock didn't save. Start up on power connect and record is the same without the battery, however on power disconnect the SJ4000 turns off immediately, yet it will save the last file.
The SJ4000 gives you the ability to lock a file while recording, just press the Mode button twice. Once to turn the screen on and the second locks the file. Normally it's only one button press when the screen is on, yet with the screen off the Mode button wakes the screen first. The good part is the Mode button is large and easy to find so no hunting to find the right button. A key shows on the top of the SJ's screen to indicate it's locked and locked files show in windows explorer with "SOS" preceding the file number and in a separate folder so it's easy to find them.
The screen is 1.5 inches and has a nice set of icons to indicate your settings. You can see I have mine set for 3 minute clips, loop recording, HDR on, 1080p and the microphone on.
There is a blinking red dot on screen, a blinking blue light on the back as well as a blinking yellow light on top to show that the camera is recording. The car mount blocks the blue recording light as well as the red charge light. My simple fix was to drill a small hole in the back to reveal the light. I plan to make it bigger in the future to make it easier to see in daylight.
Mine came with the updated LCD screen and PCB version. The only real difference is the new PCB allows for AV out/FPV, not really used on dash cams.
If your stock FW version is 20140324 and previous - you have the OLD PCB & OLD LCD
If your stock FW version is 20140329 and above to 20140527 (not included) you have the OLD PCB & NEW LCD
If your stock FW version is 20140527 and above you have the NEW PCB & NEW LCD
Pros
Super sharp 1080p video, good night performance and a 170 degree wide angle lens in a nice small package.
A good support group and easy to find information. I have been using the RC owners group http://www.rcgroups.com/forums/showthread.php?t=2090990
The mounts are compatible with the most GoPro mounts.
Easy to use interface with a good amount of adjustments
Can be used without the battery
Cons
The only real con I had with the SJ4000's performance was the Mode button being not sensitive enough and sometimes having to push it twice. Upon further research I realize this is a known problem with some cameras and luckily there is an easy enough fix.
The car cradle also blocks the recording and charging lights yet it's a simple fix with a small hole drilled in the back
The battery charge times were long for such a small battery, taking about 4 hours to charge.
Conclusion
I know many will not want to leave a GoPro looking camera in their car or on their bikes full time. I think that is about the only reason this camera hasn't gotten a big following here on DashCam Talk. Looking beyond that, it's a great camera, the video is sharp and clear and the camera gives you all the options you need in an easy to use format. The 170 degree lens surprised me compared to my A lens Mobius. The view is much wider while still being sharp.
I'm really impressed with the performance of the SJ. I think it's a great choice for someone who is looking for a great small camera at a good price and shouldn't be overlooked.
