So I been having intermittent issues with my dash cam over the last year, it finally seemed that the problem was the memory card. Now looking further into it, the issue at hand is that most memory cards aren't suitable for the 24/7 continous writing in surveillance/CCTV mode enabled dash cams. A typical 32GB card will hold maybe 2, maybe 4 to 5, hours worth of content which means that it is probably eating through its entire capacity's worth perhaps 2 or 3 times a day. Most common memory cards are built on a cheaper variety of memory chips called TLC NAND, which have relatively short write endurance of around 3,000~5,000 cycles, which apparently translates to about 150~300 total overwrites. Examples include be SanDisk Ultra cards... Then there's MLC and SLC NAND, which without going into working detail, get more endurance. Doing some simple math, 150 total overwrites, assuming the card does it twice a day, a cheap memory card could eat through its entire rated write endurance in less than a year! My older dashcam-used memory cards, even with formatting, cuck up the camera every few seconds now. Anyway, I notice now there are High Endurance for video surveillance memory cards by SanDisk, Lexar and Transcend, advertised to handle at least 2 years of continuous recording. I'm trying out the SanDisk card, will be interesting to see if it's still problem free after warranty is over. Anyone else tried those, or other brands of cards? I'd also like to get some more data from other users about how long their memory cards are lasting in cams.

So my Finevu CR300HD and CR500HD battery went dead. Thatz the normal thing for Finevu car cameras with lithium polymer batteries. After reading dashcam forum on how others replace their battery, I going to replace mine my way. I was thinking, since the lithium polymer will be dead in one year's time, why not just solder a connect and replace the battery externally. Much easier than open up the camera again. So my journey starts : Forum read was here : https://dashcamtalk.com/forum/threads/problem-with-the-finevu-cr-300hd-internal-battery.1083/ Detailed instructions of how to strip the camera here : http://www.blackboxmycar.com/blogs/news/10846777-battery-replacement-instruction I opened up mine as per above instructions. Remove the battery, de-solder the circuit board from the battery and solder the JST connector wires. Using my dremel, I drilled a nice clean hole thru the two casings.

I am wondering how a distributor sell a item CR300HD that is listed by manufacturer for 295000KRW(SGD330 equivalent) as SGD599 here in Singapore? Are you blatantly ripping us off? Given you as the "distributor" Normally I would expect the price difference to be minimal from what they are recommended/selling!
