Elikliv Action Camera, Helmet Sports Video DV Camcorder, 4K HD Full HD 1080p Bike Bicycle Motorcycle WiFi Webcam for Vlog Cam Waterproof 10M, Car Video Recorder

Water-resistant HD Camera. A Sandisk Extreme Pro Micro SD card for USB 3-speed transfer of video content is advisable. Colour saturation and overall exposure in daylight are good but not UHD HDR. The camera mounts are what I wanted for my project. RunCam 2 4K on the pitch up/down 1/4" screw mount with velcro bottom to stick to the helmet. Worth the cash for that bit alone.

The media could not be loaded.  Ignore the specs. This isn't 4K / WiFi etc etc.It produces 1080p/720p video encoded as motion JPEG. The frame rate of the video files produces are 30 fps however if you step through them using something like mplayer or VLC player you can see that every third frame is a duplicate of the previous one making the effective frame rate 20 frames per second. This applies to both 1080 and 720p mode. The resolution is clearly not 1080p or 720p in the respective mode but looks like a lower resolution, upscaled - however I've found the image quality to be decent and can use if for reading number plates etc.The angle of the camera view is 120 degrees as advertised. The camera itself is easy to operate, one button at the lens end of the body (long hold) to power on and off, and a button at the other end to start and stop video. on and off and stop / start is accompanied with a strong vibration to let you know the button press has been responded to as well as a blue light which comes on for power and a red light which comes on for recording in progress.The video format isn't h.264 in an mp4 or mov container like most cameras but is in an .avi container and is Motion JPEG encoded. This means that if you're looking to edit in something like iMovie then you'll need to convert it to h.264 first (there are free tools to do this, one of them "handbrake", or you can do it from the command line with ffmpeg etc).As a result of the motion JPEG encoding the files are quite large. We're talking 300-500 megabytes per 3 minutes of daytime footage in 1080p (about a third less in 720p) - however as motion JPEG take a lot less processing than h.264 the battery life is a lot higher. I've tested this in 720p mode and got 190 minutes split between two rides (one night time and one day time) and also in a single ride in 1080p I got just shy of three hours out of it.There's a timestamp in the bottom left hand corner which can be turned on and off as required. When the camera is powered on with an micro SD card in it, it will create a file in the root of the filesystem called time.txt. You can set the time to be a curate by picking a time a short while into the future, writing this into the text file (vim, notepad - whatever) and saving it and unmounting the camera from your computer. Wait until 2 seconds before the time you entered and press and hold the power button. The camera will read the time from the file and set its clock then which should be pretty accurate.The video is stored by default in three minute sequentially named video files. This can be changed to be a different number of minutes by changing the 3 that appears after the date / time in time.txt. There's also a Y which can be changed to an N to remove the time stamp here also.There's no delay or dropped footage between the video files created meaning if you happen to need evidence from between the rollover between one video file and the next you'll have it. I couldn't detect a single dropped frame and when editing footage back together there's nothing missing.The camera records in a loop, whereby when the micro SD card is full, the oldest 3 minute video is deleted to make way for the next one.The camera charges through a USB cable but this is not a standard micro or mini usb B cable like you might expect but a custom cable. I think it might be hard to find a replacement should you lose it however it looks identical to the Nikkon UC-E6 cable (which can also be found on amazon). I'm not saying they're definitely the same but they're probably the same cable.The camera itself is housed in a metal cylindrical body. It's looks waterproof - it'll certainly cope with the rain.The mounts that come with it consist of a clasp that clamps around the body of the camera and gives you a standard tripod socket. There's a handlebard mount which presents a standard tripod thread to join with the clasp and also a helmet mount which again presents an angle adjustable tripod thread to connect with the clasp. The helmet mount has an adhesive pad to stick to the helmet and / or you can use the velcro straps to tie through the vents at the top of a bike helmet.Personally I don't bother with the mounts and have just cable tied the camera directly to my helmet with a small piece of foam padding under the rear to angle it down a bit.Again, the quality isn't amazing and the video is 20fps in reality but it's good enough for recording evidence and is perfect for a install and forget (other than charging it up) situation. The sound is fairly quiet and is easily overwhelmed by windnoise. Again this is nonstandard format, 16kHz PCM, mono so will need to be converted along with the video to standard .h264 / AAC for editing in something like iMovie. Personally I can't see editing being a problem unless you're using it to do performance art ranting at motorists like some people seem to want to do. AVIDemux will do a perfect job (for free on windows or linux) of cutting and pasting bits of MJPEG together and joining the sequential clips together into one video then converting the end result to .mp4 for you. It can also do image stabilisation (which the camera itself, obviously, doesn't)There's a minor gripe about the lens i.e. it's a decent wide angle lens sat behind a plastic flat lens cover meaning there's sometime a reflection of the lens itself (like a polo mint shape) barely detectable in the footage and you can get some lens flare that from street lights or the sun which is a bit worse than normal due to this but this is really nit-picking at this price).So far so good. I'm very happy with the resulting video. For £32 (using the "click for voucher" thing on Amazon to get £6 off) this is an absolute bargain.The camera is a lot less obvious and a lot more streamlined than the GoPro types that you get on Amazon.I don't think there's too much more to say about it. Very happy with the purchase :)

There is no tf cardInstruction booklet is the worst English I have ever seen.Video stopped working after 2 days.I feel swindled!

Records everything sound quality not so good but not needed

Reasonably easy to use, but dreadful sound. Distorted and loads of wind noise.

IF you are using this for making mountain biking videos, the frame rate is too low.If you are using this for a helmet cam for safety, the camera is far too blury and low frame rate to capture number plates, so it useless.Battery lasts an hours or 2 and has a very unusual charging cable (not USB variant like everything else).The title of 4k is also a lie, it is 1080 or 720 video.Just isnt worth it

The picture quality is good for the price, the only disadvantage is the battery life isn't very long, so you need to plug it in if you are using it for long distances, my husband doesn't go as far these days so it's been great and at a good price for a first time user.

The media could not be loaded.  I use this on M/C helmet, had to modify holder for it to fit. Sound pickup not to great but video coverage and footage realy good. Records in 3 minute bursts. I have had about 3 of these now. Average lifespan about 3 years then battery life starts going, but in constant use. Will last a good 8 hours. I also modified the attachment so it would fit to my hiking stick, very lightweight and usefull, not perfect but practical. With right editing equipment you can get still photographs from your shots. If you want to see quality whilst in use look me up on you tube, Mark Gibson cold fell is a good start.

The camera's best feature is the battery life and the vibration letting one know it's on or off. is useful the rear screw on cover is a good idea as well. Pity the manufacturers didn't put these good ideas into the picture quality that is TERRIBLE more likely 480p and in my view definitely NOT 4k
