Focusing The Lens Using The Webcam Method
Quote:
Personally, I would not advocate trying to force the lens to turn with pliers without first carefully picking off all the glue, and on mine that required getting access to the underside of the lens module by taking out two more tiny screws so you can lift the circuit board out of the case. When you do that, I'd advise not touching any of the soldered connections with your bare hands. I bricked two old 808's doing that. I wrapped my circuit board with masking tape to insulate the bare connections before handling... Better safe than sorry. Whatever you do make SURE you hold the square lens holder base securely when you finally turn the lens barrel so you don't apply any force on the ribbon cable connecting the lens holder to the circuit board. I found my fingers were too big, and the lens barrel too small and too hard to turn without my fingers blocking the camera image while I turned it. I used tweezers to grab and turn the lens barrel so I could turn it and see the image change while holding the camera fixed with my hand. For reference, turning the lens counter-clockwise when looking from the front the focal point will move closer to the camera, and clockwise moves it further away. I used the webcam display method to focus, but found that the normal 640x480 native web cam video size a bit too small for my eyes to see distant fine detail well enough to get the best focus. So, I used VirtualDub editor, which has a nice video capture function under the "file/capture AVI..." menu. To use this, first connect your camera and toggle it into the webcam mode before booting Vdub. Then select the above menu item, then under the "device" menu, select your camera which should show up as "USB PC camera (direct show)" and you should see the normal 640x480 image on your PC display. If that image is not large enough for your eyes, click the "video/stretch to window" menu selection to enlarge the image to whatever size you can drag your window borders. I will be finishing my "focus hocus pocus" tomorow... hopefully with better light than we had here today! I will try to get good focus across the entire display from corner to corner. This may mean that both the center and edges are a VERY TINY bit "out of focus" because I don't think the cheap lens can get both areas in their best focus at the same time... we'll see. |

AviDemux Filters
I tried some AviDemux filter tweaks on my original HD key cam video test clips to reduce the over-saturated (to my eye) color, increase the brightness a bit, and sharpen the detail slightly.
This not only made the colors look more natural, but also brought out detail in shadow and under-exposed areas, and lessened the camera's center "hot spot" and edge vignetting a bit, an unexpected bonus. The clips were cropped and combined with one click of a custom (one-line!) AviSynth script icon, which does its magic and outputs the stream into Vdub for final saving. Here's an abbreviated before (left) and after (right) side-by-side comparison video. For best viewing, click on the video player window title to go to Vimeo, then expand the player there to full screen and toggle "scaling" off in that window to view the video in normal size. The sharpness tweaks are most noticeable if you pause the video and look at the edges of distant trees, etc.
<edit> CRAP! Vimeo did not render these in full 1280x720 frame size, so the full screen with scaling off method I mentioned only shows them half size, which makes the changes much less visible. Oh well, if you're interested you can download my original upload within one week of today's date. <edit> |

Tom,
Very obvious differences between the 2 before and after enhanced videos. Which of the 2 you think is closer to natural colour? I've tried using the free AviDumux to stabilise one of my videos but It didn't turn out very good. Are you using the premium AviDemux? |

Hope you are able to fit the lens on both your cameras! I like to put it on my planes as it makes the movements look smoother because of the wider angle of view. It is not GoPro quality, but at least you don't have the irritating GoPro bending horizon.. ![]() ![]() /Jan |

Despite the small inconvenience, I would much prefer to have some intact files than none at all. If I am recording 6+ hours of continuous video and then, because of power loss or whatever, the recording fails, I don't want to be left with a heap of scrap. Give me file parts any day! I may have underestimated the manufacturers, but truth is that you should never put all your eggs (files) in one basket - and never touch a running system... NEVER |

Hi guys,
I joined the club and finally got a HD from Diana (hxelepro360) He removed the time stamp for me but the file creation date is a year off. How is this corrected? Never mind I found it as I was supposed to! I'm really glad I found the thread before I purchased the HD. The fob thread is and was most informing. I'm stoaked how this thread took off and is still climbing! PC Galaxy(ebay) has 4gig class 6 micro sd cards for 7.5 bucks, 12 bucks from TW in 5 days. The HD cam only took 8days, now if Hobby King could get their act together like the others! |

I just got an email from internet-shop365 that my camera shipped today. When I ordered it last week they were out of stock, which would have been nice to know prior to ordering. They sent me an email to say they would be getting them in on the 10th, which they did, so no harm no foul. Can't wait to start messing with it.

If you click on my Avatar, you'll find links. There's one that Tom hasn't listed yet, but I can't confirm it's good. It was a little cheaper ($0.10), but now is about the same. I click every day because sometimes they have sales, but seems shorter supply now is keeping prices up.

Thanks for those who provided feedback on the close/continue recording function. Valid points. I'm not a .MOV fan to begin with, so never dug into it's file structure. But it seems strange that it does not leave enough room for updating it's header without shifting the entire data space if files get large. Oh well... don't want to get into that any further.
I got feedback from my vendor "camera guy" that they can modify the camera firmware for continuous recording if there is a demand for it. He also made ta similar case (having something rather than nothing) against doing it. Since we already have a pair of firmware patches that toggle the date on/off while keeping the close/continue ON I asked if they can provide a new pair of firmware files that toggle the date on/off while keeping the close/continue function OFF. That way a user can pick his preferred flavor, and toggle back if his taste changes Something for every one!

Tom - no sweat, we are all in this together! I saved my links to my "blog page" for my own convenience, they link direct to the cams not the the store, which then would require further search. Just easier for me to quick scan for prices, but requires updating which I might not do.
I don't know if my 5th vendor is one of the 8. Anyway keep up the good work! |

What does this mean? What is a bad public atom? I had some short test clips on the SD and thought they were erased, is why the vid is number 8. Its the second part of a test run attempting to see what the thing could do on the brim of my hat (hat cam) the second part works as do the other test clips. the first part that will not work is 1.58 GB (1,705,705,472 bytes
Error -2002: a bad public movie atom was found in the movie (PTDC0008.MOV) thanks Tom J PS: there times when this thing will connect quickly on my PC and other times the my computer just doesn't see it for a few min. Also this is when I first plug it in after using it, the red charge light is on. Perhaps it won't read until it has charged some? |

I get an annoying "cracking" sound on the recording only when I have the car charger plugged in. Did anyone else experience this? I guess its not possible to remove it somehow, is it?
Heres a sample from a 2 hour test vid (filled my Kingston 8GB).

They propbaly meant "corrupted byte"... As with the other keycam, make sure it is close to fully charged before doing anything with it.

Also, I got similar static burst at about 1 sec. intervals in my first test clips in some, but not all, of the test clips which I merged and posted earlier. The only explanation I have is that all the clips were taken in and outside the front and back doors of my house. The clips shot inside on the bottom floor and just outside the back door have the static bursts. The one upstairs and outside the front door do not. I have both wireless internet and wireless digital phone router/base units in close proximity to the clips that had the static bursts. Noise pick up from those perhaps? I have no explanation... only hunches. |

I had assumed (really bad idea, I know), that when the battery voltage got dangerously low, the camera could sense that, stop recording, and save the file. That may have been a bad assumption! I am doing a test right now with a partly discharged battery to see what happens to a file when the battery gets low. If the file is totally lost lost, I would not want to risk that. And knowing how many of the old 808 cameras had problems with the battery not lasting very long, the 20 min stop/save/continue sequence is not so bad after all. I know there are one or two people working on an external power source for the camera, and perhaps they would still like to have a continuous recording option? If so, please respond to this post and I'll advise my contact accordingly. |

BRB, going try it now...
Will edit this post!Edit - Nope, no go! I tried a few times, and most of the time the computer never even detected it. The lights blink and all just like when using it on Win7, but the computer just didn't see it. A couple times it did show up as a removeable drive as normal. No dice for webcam mode on XP though. (I used XP Pro SP3) |

It works exactly the same in XP Pro as you described on the previous posts - push and hold shutter button, then power button until yellow LED comes on, then XP chimes that it has detected a new USB device. Bingo. Your suggestion about using Vdub works wonders as well, and I got my cam focused using this exact method. Eureka! Thanks again, Tom clx1 |

Windows 7 Home Premium with ReadyBoost
This is FYI for Windows 7 Home Premium who are playing with sticking a thumb drive and configuring 4 GB or so on a thumb drive for extra cache. Well, I just noticed the playback of several .mov HD videos were hanging up for a couple of second on the video but not on audio. Scratching my head I wondered what was different. The different was the thumb drive was plugged in and configured for 4 GB of Readyboost extra cache. When I removed the thumb drive the videos no longer hung up. I will try reconfiguring the Readyboost on the thumb drive and see if the problem occurs again.
Bill EDIT: I simply removed the thumb drive configured with 4 GB for cache and plugged it back again. The video playback hanging up did no recur. Go figure. |

The focusing has turned into 3 day ritual with lousy weather and poor lighting combined with this new Vdub/webcam issue. I got a small range of lens position defined... just need to tweak it within about a one notch band on the lens ring. It's looking like the positon the lens was in when I got it was VERY close to being as good as it gets! I'll just shoot some short videos at various points in my lens rotation range tomorrow and run them side by side to pause and look at fine detail to see which is best. Hand holding the lens and trying to focus just has too much motion to clearly see what's what for me. |

Hey Tom, just an update... After seeing other's have the camera working on XP, I decided to investigate further... I was using the front USB ports on the XP machine. I've had issues with those in the past, but only powering external hard drives. (A 2.5" laptop drive in a case, and no external power supply. Not all USB ports will supply enough power to run up the spindle!) I crawled under the desk and hooked a USB cable to a rear port, and what do ya know?! Webcam mode works like a charm on that machine now! Might be something to consider. Try a different port and/or cable, maybe it'll work for you?

New External Power fo the HD Key Cam!
Look what was just sent to me by my "HD Camera Guy":
http://cgi.ebay.com/Key-Chain-HD-Camera-DVR-Video-Recorder-Webcam-30fps-11-/160531252866?pt=LH_DefaultDomain_0&hash=item256068 8682 The new package of accessories for the HD key cam includes an external "emergency battery charger" for just $2-$3 more. You probably have questions, because the ad doesn't tell anything about what it does! I THINK it may function just like the car charger to power the camera while it records in parallel with the camera's internal battery. I have already asked the HD Camera GUy these questions, and may have answers by tomorrow morning: 1. Will it allow the camera to take power from it AND the camera internal battery in parallel and take video at the same time? 2. What is the capacity of the emergency charger battery (mAh?). 3. How much recording time will the camera have with both it’s internal battery and the external one connected? 4. What kind of battery in the emergency charger (e.g. LiIon?) 5. How much does the emergency charger weigh? 6. Are you selling the emergency charger by itself for those of us who already have the camera? If so, what will be the cost (including shipping?) I think it would be possible to just substitute any single cell lipo for the one that is in the external "charger" and record for much longer periods. That would make a continuous recording function much more desireable if it takes the camera's internal limited record time battery out of the equation. I'll post more when I know more. |

Will the internal battery (if partly charged) take over if I disconnect the USB while recording? What happens if I reconnect the USB after a few seconds? I am hoping that the camera continues recording without interruption, and will continue until the card is full. If this is not the case, then this is a BUG, IMO. Now about your firmware idea. Its a bad idea How is the manufacturer expected to supply and keep synchronized 4 different firmware versions?(timestamp on + split files, timestamp on + big file, timestamp off + split files, timestamp off + big file). Also, there is always an element of danger when updating firmware. I hold my breath every time I have to update my motherboard, video, router, telephone etc. There is only one clean solution, and that is a parameter file similar to that used for setting the time. If the camera has been designed with too little internal memory, then it most probably won't be possible to use a parameter file. My suggestion for your "HD camera guy": (to replace the current date file - forgot the name) File name: Params.txt File Contents (// is comments, should be ignored by firmware so that we can have a documented parameter file): Date: 20110112 // YYYYMMDD Time: 150549 // HHMMSS DateFormat: DD.MM.YYYY // or any combination, e.g. MM/DD/YYYY, MM/DD/YY, DD-MM-YYYY, etc. TimeFormat: 24 // or 12 (with AM/PM) Timestamp: OFF // or ON Split: Y // or N This is similar to a suggestion that I believe you made yourself and is similar to the (old) DOS/Windows ini files. The order should not be important and using parameter names makes the file flexible if other parameters are added at a later date. The file should be automatically deleted once the parameters have been set. Any serious firmware programmer should have used a configuration file from the start, but I doubt that the programmers have a clue what end users want or may want, which is a pity. Maybe through you, we have at last a chance of telling the manufacturer what WE want. Keep up the good work, and maybe you will go down in Keychain history

Does anyone know what the thread size and diameter of the lense barrel is on these cameras? While I'm waiting for mine to ship, I am looking into some possible lense replacement solutions. I have found some prototyping lense adapters made for OmniVision sensors that could possibly be retrofitted.
My goal is to make a m12 x .5 adapter so that any of the hundreds of available m12 x .5 lenses out there could be used with this camera. I feel that the vignetting issue could easily be solved by using a higher quality lense than the one that comes with these cameras. I have found some very capable lenses that are relatively inexpensive, with FOVs ranging from 97 degrees up to 127 degrees. Of course, they can't be used in conjuntion with the stock lense, so this would take some serious modification to the case, which I have no problem doing. It would also require some surgery to the actual sensor assembly, which I am ready to do if it will yield some worthwhile results. I probably should have ordered a half dozen cameras to cut up ![]() Doug |

You guys are brave. I bricked yet another standard #3 just by trying to focus it. I didn't see any sparks or smoke, but there was a brief, acrid electrical smell. Then it was a paperweight. I was being careful, too. I wouldn't dare try it again with the basic #3, much less the new HD models.

I checked how my 808HD record movies until the end of the battery. The camera was loaded until it extinguished until the red LED.
I turned on the camera. I pressed the shutter button and the camera recorded a preliminary 10000kbps. Recorded the two parts after 20 minutes and an approximately 1.5 minutes. After removing the files I loaded the camera again until the red LED is extinguished. I turned on the camera, pressed the button twice Power / Mode button and then shutter. This resulted in the camera started recording under 7000kbps. I continued to the end. Recorded the two parts after 20 minutes and one about 2 minutes. Recorded movies can I play with VLC media player 0.8.6c, BESTplayer v.1.0, BESTplayer 2105, Dziobas Rar Player 0.009.52, plus DivX Player v 8.1.2. Avidemux 2.5.4 The application reads and treats all parts recorded on the camera. VirtualDub 1.9.9 The application reads only the last part recorded on camera less than 20 minutes. |

Since you said manually stopping the recording works, that makes me wonder if the date removal firmware we install is a full copy of the firmware or just a patch for part of it. I'd ask the vendor to replace your camera if he cannot find a solution.

Some Lens Focusing Tips For the Discriminating User
I've gotten to the point where my final lens tweaking will be done during a bright sunny day. According to the weatherman, we can expect one here sometime about mid-March
, so I'm going to post what I've found helpful for me to get that "best" focus. But I'll give fair warning you have to be anal about it to do this!I think most of the camera videos I've seen posted here show the lens comes fairly well focused from the vendor, so unless you really don't like what you see, my best advice is not to bother with refocusing! I'll skip the part about removing the glue on the lens so it can turn and taping over all exposed circuit board components to avoid shorting and static discharge, and get right to the actual focusing nitty gritty. I could NOT convince myself I had the best focus by viewing a web cam display on my PC because of too much motion while hand holding the camera, difficulty in turning the lens and not blocking the view at the same time, and no way to really compare one setting with the prior one at both far and near distances other than by memory. But YMMV, and this may be good enough for you. My goal was to optimize distant object focus (for AV purposes), while getting the depth of field as close in as possible before the distant focus deteriorated. And good focus across the whole video frame if possible. I used my focus as received since it was pretty good and a good starting point, then I marked one of the "indent valleys" in the knurled ring on the lens barrel with paint (so it doesn't scrape off while focusing), with a matching line on the fixed base. There are twelve of these valleys, so they are 30 deg. apart, and I'll call the rotational angle between two valleys in the following procedure as one "notch". Here's what I did:
Good luck with your focusing efforts! |

I love your thoroughness. So, does it appear as though clockwise or counter clockwise was the right way to go to dial in your focus for Aerial video? I tried 1/4 clockwise and it was lousy. Then 1/8 turn CW and didn't like it so I reset it to original. Also, I noted the camera guts is one tight fit in the case. It took multiple attempts to tediously place the innards in the right location so the lens was positioned correctly and case closed up tightly without forcing the screws to close it again. I did NOT have that problem with the two Basic V3 key cams. Bill |

In any event, I think there's no right or wrong direction to try to focus better. But if the normal position were always slightly towards the near field as the old 808 cameras seemed to be, then clockwise rotation (moving the lens closer to the CMOS sensor) would generally move the focal point further out as we've discussed before. Your smallest test rotation of 1/8 turn was equal to 45 deg. My "one notch" initial turn was only 30 deg., with each 1/4 notch fine tuning increment being only 7-8 deg. So you may have over shot the decent focus range on both far and near sides with your larger rotations, making both look much worse. If you try it again, use the "one notch" or smaller increments. I haven't put my case back on yet, waiting for that sunny day final test, but I think the larger capacity battery is the main reason for the new tighter fit. |

Tom, I understand now. I probably did overshoot the sweet spot. I was lucky enough to not lose my paint mark. The pudgy lipo just barely fits in the case. I ready to order the emergency battery power accessory for $3. I bought 16 Eneloop 2000 mah AA's (the zenith of NiMh batteries) to power my DX6i and DX7 Transmitters. That means I have four extra batteries to use elsewhere. One of those would give me a lot of video time with HD camera. Bill |

The parameters (just a few bytes) must be saved to the non volatile memory which is the SPI chip (the one with the 8 legs) in this case. If the processor has some non volatile memory, this could also be used. The parameters MUST be saved to non volatile memory - please make sure that your contact guy understands this. Failing to do so will result in loss of parameters if the battery is disconnected. The #3 SPI memory is split into two parts, the boot code and the firmware. I assume that the #11 has the same mapping. I don't know if space has been reserved for parameters in the non volatile memory. If no space as been reserved for parameters, this is a VERY BAD design, and making a universal firmware could become a bit more tricky.... |

I wanted to see whats inside the auto plug so I opened it up and slid out circuit board...I see a date but I doubt it could be used for the model of camera unless you knew they packaged them together from factory... ![]() |

I happen to have my camera out of its case right now, so will post some pics of both sides of the circuit board shortly.
While your car charge is open (if it still is), can you tell us how many wires in the cable going to the camera are soldered to the circuit board (looks like just two (+ and ground) from you pic. How are the remaining wires in that cord terminated? Quote:

finster, can you say what's written on the 8-pin chip in the charger board? I can't make out anything from the picture.
Well, in the picture I see a coil, and that suggests this is a switched supply to efficiently generate 5VDC from the car battery, with switching done by that chip. But I don't see anything suggesting that any USB intelligence is there. So if this charger is special in some way, it would have to be in the way the data pins are connected. Has anyone succeeded in charging an HD using a dumb wall wort USB charger? |

PS3 controllers can be charged with dumb chargers, but the controller gives no feedback that charging is taking place. When connected to the PS3 USB it blinks, on a dumb charger it does not. I have heard that by raising the voltage on pin 2 it does communicate with the led, but I haven't tried it for fear of bricking! (they are more expensive than HD808's)

!It has already been mentioned by a user in a prior post that a generic wall wart USB charger will NOT charge this camera. I just tried it, and the red LED does not light which is the normal charging indicator. Does that mean that it really is NOT charging, or does it just mean the dedicated charger is not connected, making you THINK it is not charging? I haven't done any tests to confirm either way, but I did plug in my smart wall wart USB charger that came with my JAZZ HDV178 camera, and it DOES light the LED, which goes out after a while indicating it did put in a charge, I guess. Some tests with a dead battery would be needed to tell for sure what's going on. |

Here's the pics of the HD Key Cam circuit board. What is the difference with yours that you mentioned? Were you able to determine how the USB data pin wires are terminated? |

I have not attempted to charge this with a PC yet but I did notice the red LED coming on momentarily when I used it as a webcam. And I know my non-powerd USB port on my PC has successfully charged other devices like smartphones which have 1200mAH batteries, so they are likely rated at 500mA output also. clx1 |

I also used a Blackberry wall wart charger when I tested mine. I just tried it again, and saw the red LED flash for a fraction of a second when I plugged it in... might have missed that the first time. I then tried my JAZZ "smart" wall wart charger, and the PC USB port, with same results. The red LED flashes like this then goes out when the battery is fully charged. The first time I tried this with the jazz charger the red LED stayed on for several minutes before going out, so I assume it was topping off the charge during this period. And it could be the wall warts have some kind of lithium charging safety circuitry in them that terminates the charge at slightly points, making the LED act differently, too. If I had time and desire, I'd just measure the voltage on the battery after different charge cycles with different chargers and see what the battery is doing directly from its output wires. |
