My arthritis still has me working on my workbench so I started piddling around with my train cameras again. I ordered a new SQ23 and it is still on the slow boat from China.I got to looking to see if I could fit a cube camera in a locomotive. I have several Proto E8s sitting around (don't particularly like them) and after getting into one I found out there is room for an SQ8 inside the Proto E8, if you want to put some elbow grease to it.I chopped a fairly large chunk out of the front frame and the SQ8 fits perfect.I did the initial cuts with a Dremel cutoff disk then the ⅜” metal cutter.I finished angling the remaining frame pieces with an 8” metal file.I used Amazing Goop to attach the SQ8 to the frame.The Proto shell just drops on the frame.If you make the shell so it’s easily removable it can be removed to have access to the camera controls and SD card. The micro USB connector is easily accessed for charging the onboard battery.I can pull the shell without disturbing the frame or wheels on the track to press the control buttons on the SQ8.The SQ23 that hasn’t arrived is a bit larger and I’m not sure it will fit inside the E8.Mel My Model Railroad http://melvineperry.blogspot.com/ Bakersfield, California I'm beginning to realize that aging is not for wimps.
mkepler954I decided to go with a 9V battery rather than track power to maintain a clear, uninterrupted picture on the TV.
Yes, for this application, track power is overrated, even though it seems like a tempting solution. Most of us will use one of these rigs for a few hours a year. If there's space fior them, best to keep it simple with batteries.

On my latest camera car using the SQ13 camera I didn’t add any lighting but it needs some light in my tunnels. The SQ13 doesn’t require much light and I’m kicking around adding a single 5mm super bright Warm White LED. There is enough room to add an LED a bit above the camera. I went with the pan mount on my recessed flat car primarily for using it for filming my scenery where it doesn’t require lighting.Two 3mm LEDs probably would work, one on each side of the SQ8 through SQ13 cameras.Mel My Model Railroad http://melvineperry.blogspot.com/ Bakersfield, California I'm beginning to realize that aging is not for wimps.
I'm interested in acquiring a camera for my layout As well. I have two tunnels that have no access (no lectures, please, I understand my mistakes!) and occasionally need to retrieve a derailed or uncoupled car Or stalled engine. I am curious if there was any ambien light in your tunnel trial or just the engine headlight? Also, would the engine headlight be enough illumination if the camera was mounted to a flat car being pushed by the engine. Thnx.
I just received a Microcam Wireless Surveillance Camera Kit w/ Receiver & Mini Wireless Camera bought on eBay. I decided to go with a 9V battery rather than track power to maintain a clear, uninterrupted picture on the TV. A trial run thru a dark tunnel with only a loco headlight worked perfectly. The camera's antenna was able to pass thru 8' long tunnels with no problem. I will install it on a dummy diesel with a bright LED bulb. I'm a happy camper and thanks to all of you for your ideas!

Hey Mel-I'm thinking something like this might help with the overall darkness and gloom of my videos.Did you mount the additional headlights on the pusher engine behind the camera car? Does the light from all six LEDs shine through the front cab windows?
EDIT:
I don't have any lighting on my camera car. The window lighting is in a E7 with a pinhole camera onboard. Sorry I have several camera cars and camera locomotives.
Yes.
Does that cause any mysterious shadows or anything?
No shadows.
Were these LED headlights in addition to the F7 headlight?
Yes, I added three 3mm super bright LEDs behind each window, total of 6 LEDs. I paralleled them each with it’s own resistor. I made a housing to not only hold them but also to block the light from the cab and side windows.
Do the LEDs require some sort of shaped nozzle port to direct and focus the light to shine down the track?
The LEDs are recessed in the housing about an ⅛”.
Do your AA batteries power the headlights, or are they receiving power picked up from the tracks?
I use two Lithium AA size batteries (total 8 volts in series) for my onboard 5 volt electronics and a 5 volt regulator from 8 to 5 volts.
I'm thinking along the lines of fabricating a flatcar with some low-level ditch lights and some high-level raccoon hunting lights. Do you have any recommendations how to fabricate such a thing?
I would make them easily removable.
The flat car itself is simple enough. Just a flat piece of styrene with bosses fore-and-aft to attach the trucks with screws or bolsters. I will need the type of trucks to pick up power from the tracks if I go that route.
I would use a commercially made flat car, no sense making things harder.
Any advice? Or, I think I have enough room for two or possibly three AA batteries or AAA batteries behind the camera. Any advice on that kind of power arrangement?
I really like Randy’s idea of using a DC to DC converter to get your 5 volts. Unless you plan on using your camera car a lot I would just operate on charging the batteries and not ues track power. I have an onboard charger to keep the two Lithium cells charged because I sometimes use my camera car all day long just dinking around.
For an hour or so of use you could use the onboard camera battery and just use a single Lithium 1000ma battery for lighting. I single 4 volt Lithium 1000ma battery will run the LED lighting a long time and you wouldn’t need an onboard charger or a 5 volt regulator. Just resistors in series with the LEDs and a switch to turn them off.

RR_Mel I thought I would mention the camera lighting in tunnels. The SQ7 through the SQ13 have very good low light level video. I have a camera pusher E7 that I installed 6 super bright LEDs recessed in the front windshield that I control the on/off by DCC decoder and with them on the video is brighter than daylight. The normal LED headlight is more than enough light for the cameras to see the tunnel walls, track and ties.I made a battery cover for my camera car because the VOF (view of field) sees the top of the on board batteries. I use portion a F7 cab as a battery cover and installed a 3MM Super bright Warm White LED in the headlight and it has plenty of light for the SQ cameras. The video looks like looking out the window over the F7 hood. Kinda blows it though when I pan the camera.

EDIT TO ADD a photo to show that a rechargeable 9V battery easily fits in the bottom of an N scale double-stack well car. In this scenario, the camera would sit far forward against the ladder handrails.

rrinkerThe problem with a phone camera is that it needs a whole lot of extra parts to actually generate a usable image - in a phone, most of that is integrated in the main SOC
is a smartphone camera different than a common web cam?
i don't think it's so much the size of the electronics as the size of the camera, the lens.
if cameras have a standard interface, can you use the electronics from a $20 webcam put in the B unit with the small smartphone camera in the nose?
the advantage of a wireless webcam over a baby monitor is you don't need to be w/in RF range. the remote operator of a loco can view the webcam in the nose of the loco he operates remotely to see signals
i wonder if we would be having this discussion if it weren't for the virus
The problem with a phone camera is that it needs a whole lot of extra parts to actually generate a usable image - in a phone, most of that is integrated in the main SOC. More and more custom image processing is being done to extract quality images from such a tiny sensor - it's much the same as film, the larger the starting point, the finer the details and the more you can enlarge it without losing said details.

GregThere are a bunch of micro wireless pin hole cameras that will easily fit in the front of an A unit diesel. Most of the cameras are very small (⅜” cube) and have a 6” to 8” ribbon cable to the transmitter.I have an older camera that is about ¾”cube. It has a 2.4ghz transmitter that is powered from a 9 volt battery. The matching receiver has NTCS video out. It worked very good for many years.With a bit of chopping I think a SQ8 to SQ23 could be worked into a A unit diesel.The SQ8 is on the nose of a Athearn BB frame.

anyone familiar with the cameras from a phone that might fit in the nose of loco, electronics in the B unit?
RockCity Wow I didn't realize how deep this well was! I bought the Akaso 4k from Amazon and attached to a flatcar with a rubber band. I can push it, or pull it. Can't pan, but I don't care. Use IsmartDV app on my iPad to control it. Edit the video on the computer. Upload to YouTube. Not a lot of time & effort invested. Probably not the quality you guys are getting, but I'm good with it.

I really like what I see of the AKASO EK7000 . . . . but the size worries me. It looks like it will barely clear my straight on tunnel portals, I have two portals on 32” radius and I had to position the track carefully to pass 85’ passenger cars.I worked up a scale drawing of the AKASO camera on a Bachmann flat car in a Pre-Size tunnel portal.I have 5 Pre-Size HO single track tunnel portals.

I pull the SD card and plug it into a USB adapter then download the video as an AVI file in Windows. The AVI files are huge, the higher the resolution the larger the files. I’m not into video editing, I have Adobe Illustrator but I haven’t tried it.I worked with video for years but had someone that new how to use the software, I was always the equipment guy not production.Normal room lighting has always worked OK for both the SQ8 and SQ13, no noticeable grain. The onboard IR light works OK too but at the loss of color.My LED lighting works good in tunnels, better than the onboard IR lighting.Mel My Model Railroad http://melvineperry.blogspot.com/ Bakersfield, California I'm beginning to realize that aging is not for wimps.
I've made a coupla videos with the SQ11. Nothing earth shaking, just to get a feel and see what's what. Don't know yet how to edit them or upload them or post them for access on this forum. The MVI files are very large: about 500MB for a four-minute movie.
By comparison to cab videos I've seen online . . . the images are dark and grainy and pretty much out-of-focus. Close-in objects are the most out-of-focus. Trackage is oddly distorted and snaky. According to the button pushing schema described in the (translated) instructions, I should be in high-res 1080P mode. Colors are not sharp and vibrant.
The layout room is well-lit (to the naked eye) with 5000K daylight LEDs. The camera shows a fairly even illumination for most of the movie. Going into a tunnel, it gets dark for a second or two, then adjusts to where the inside tunnel lining is discernable, then blindingly white on exit, then a second or two before getting back to ambient toom lighting.
Can anyone post a suggested workflow explaining setup, lighting, action, and whatnot? Or, should we start another thread? I'm all set to piddle around and explore the possibilities, and I'll start by searching this forum (and other fora as well) for related threads. I'm only about $14 into this aspect of the hobby, but I am curious to see how things go.

rrinkerRecorded locally and then transferred will pretty much ALWAYS result in a cleaner video.
Certainly, a lot of the budget cameras provide less than wholly appealing output. Many drones are built with little thought about RF issues. But there's a trend towards Hi-Def, even with the liive feeds. The hardware is getting better, smaller, and with lower power consumption. A $30 camera today is an amazing thing vs a $30 camera from 5 years back.
But that's the low end of the scale. At the higher end, DJI and others are making some fine stuff that displays minimal if eny issues. I don't play much with that (I already have a hobby, model railroading), but unless one needs hi-def for recording or other need, the imaging from a live TV signal is pretty darn good these days in most cases. 3
Three flatcars trying out for the coveted position of SQ11 camera car.
All candidates allow the car with camera (0.9"x0.9"x0.9") to pass through the bridge portal.The obvious choice is to use the staked(less) flat car, but I'm leaning towards the open gondola because the camera sits a little higher and 'hangs ten' all the way over the front gunwale. This allows the wide-angle lens (140 degrees) to get a better picture without the lower half of the image showing the floorboards of the car.
Plus, the plan is to mount the camera on a form-fit 'load' for the gondola. This would allow me to simply remove both camera and stable base when not in use (or when doing movie download or editing).
Here's the clip that comes with the camera. The crossbuck bowtie sort of thing is connected to a spring-loaded tie clip with a very small screw. The plan is to fabricate a rectangular mass that fits fairly close, but not too snug, in the gondola. I want the base to have a fairly heavy weight to provide some motional stability to the camera.
Note: Yes, I realize this N scale stuff does not exactly match the thread title or directly answer the OP's question, and I apologize if I may have hijacked the thread (though I wouldn't be the only one), but several knowledgable members have posted information and advice here that seems to me to be useful and entirely appropriate.
The problem with direct RF is that the micro-arcing you get between the wheelsn and track, wheensl and pickups, and the motoor commutator and brushges all consipre to insert broadband interference in the RF signal - scratchy looking picture, dropouts, etc. Even on non-so-inexpensive drones with live broadcast cameras, you get interference from the motors and drive electronics, and most of those are brushless motors. The suppression circuitry you need to cancel this out tends to interfere with DCC control signals, and motor BEMF (remember those capacitors on Bachmann motors, which cause issues with BEMF and PWM drive, even when it's not from a DCC decoder?). Recorded locally and then transferred will pretty much ALWAYS result in a cleaner video.
MisterBeasleyThese days, I would go with a camera that records rather than transmits the video. It would need to be easily accessible to get the memory card out of the camera and into your computer to viewing.
It's worth noting that my Eachine DVR/LCD provides a slot for a TF card to record, as well as doing live video. The recorded video is usuall better quality than that taken over the air.
The combo camera/transmitter I use also has selectable power. Running around and underneath a layout, yep, the video will sometimes cut-out at the lower powers, but using them is best unless they prove inadequatehen use only the power needed. It's designed for drone use so there's more than enough power at the higher settings to reach a mile or more.
My camera has an RF link to a TV input device on channel 3 or 4. I liked it because I could watch the output in real time on a big TV. But, I seldom did. These days, I would go with a camera that records rather than transmits the video. It would need to be easily accessible to get the memory card out of the camera and into your computer to viewing. It would not have real-time capability.
I also had dropouts on my camera, which picked up track power and was designed for DCC. I still had dropouts, so I tried an on-board battery instead. I realized that the problem wasn't power, but intermittent loss of the RF signal transmitting the image.
It takes an iron man to play with a toy iron horse.
RandyI gave your idea a shot with goodies on hand, a 1⅜” x 2¼” DC to DC Buck Converter, too big to fit on a HO flat car. Rails to a 1 amp bridge direct to the converter, I set the converter to 5 volts and it works great on my bench test track (48”).I just set the camera (SQ13) with the 3 amp Buck Converter on a flat car for the test. The flat car has Mel Kadee coupler pocket wheel wipers, no glitching in the video.I powered the rails with my Prodigy Advance and pushed the flat car back and fourth with an Athearn SD40 with a MRC 1730 decoder.

One little thing to watch is that some switching power supplies, of the type that might be used to do voltage-to-voltage conversion or keep LiPO batteries float-charged correctly may emit RF interference that might couple to nearby sound decoders. Shielding methods do exist but it may be better to anticipate this than troubleshoot it after the fact.
