I don't know what impressed the buyers who gave this camera a 5/5 star rating. I chose this camera because I liked the look, the features and once fitted it fits well in my car as if it was part of it from the factory, but unfortunately it has let me down and it is money wasted. The camera only works when I start the engine, because that's how I have the electrical system in the car set up, and when it's in on mode, it turns off/on quite often and only stops when I unplug it, wait 20 seconds, and then turn it back on (sometimes it doesn't work the first time and I have to repeat it a second/third time). At first I thought I had a problem in the car's battery, and sure enough I already had a weak battery, but it wasn't that, because after replacing it with a fresh new one, the problem persists, although not all the time, but at least twice a week for sure, and when I drive more often, several times during the day. But since it's a fixable problem on the spot by me, I'm not advertising it - I don't want to wait 30 days for a service verdict that there's nothing wrong with the camera with a recommendation to have the car's electrics checked because of such things: ), you know, but I believe this is only a defect of one product out of a hundred produced, so it is not so much a negative as a possible occurrence of such a defect. Among the negatives I rather include the software features and the instructions for them. I still haven't figured out how to use GPS through the camera. I suspect that the GPS here is only for finding the location via the camera, rather than for navigation (I wouldn't use it anyway, as the camera has a small display and it wouldn't be safe either). I didn't find radar detection, although I wouldn't want to use it, but I don't know if I have it on or not, and if it's actually there. Even before anything GPS I would rank very difficult to use - many times one has a problem to get even only to the date and time settings and not to other functions, so by the time I manage to click through, I have nerves in a bucket and lost time. More than once I almost threw the camera out the window because of it. If I have an accident and need to show the police a record, I don't stand a chance because I haven't even gotten to that function. I'm not saying it isn't, but the very complex camera controls make it hard to discover the camera's functions. You can throw the manual in the trash, as you will only understand how to mount the camera and how to plug it into the power. You won't read anything essential to the functions of the camera, and how to operate it. Many times it happens to me that the recording doesn't automatically turn on at all, yet it is set, and I have to turn the recording on manually, so I'm already at the end of my trip and only then I find out that the camera didn't record at all (yes, I should have checked before the trip, but you just don't deal with such things and notice it randomly and for the price of the camera I would expect, that these functions would not deactivate by themselves) and many times it happened to me while driving, that I was standing at a red light and the camera did not record after the car moved, so if I was involved in a car accident, I have no proof and I could only thank the manufacturer for making a camera that does not help the victim, but rather the perpetrator of the car accident. And I will stay with recording, many times it happens to me that when I check via PC if the camera recorded the whole video, I find that the car camera, which was supposed to record an hour-long journey and recorded everything during the whole journey, but still did not capture the essential points of the video, better to say, there are only a few seconds of the video and not the whole video. Despite the fact that I had a very difficult time setting the settings to record the entire video, the camera does its own editing, so in the event of a crash I would not have footage of the moment of the collision. It may be suitable for those who make videos professionally and earn money from it, but such edits are not suitable for people who get a camera because of damage to their property - their car. I gave it one full star, but if that were an option, this camera would only get half stars, even if only for somehow working. I have 4K recording set on the camera, and having already played back even those edited videos on my 4K ultraHD TV for a test, I doubt that the camera produces 4K quality recordings - it's not essential, but if that's the reason for the price, I confirm that the camera has 4K only on paper, but the reality is different and therefore not worth the price. Alza should think very hard in the future whether it is the right place to offer these M7 car cameras from TrueCam to customers.
