High Definition Wireless Micro/Mini Video Camera with a Live Feed

Hey guys,

I am having trouble figuring this out. I understand that Arduino cannot process video streaming but I would like to either use it as a way to trigger a recording of a live stream or control turning on and off a wireless camera and its transmitter but this is not my current problem/project.

My project is looking for a mini camera with these specs:
Size: Smaller than half the size of your palm - preferred to have long and thin rather than wide and flat (camera + transmitter)
Transmission distance: 1000 feet (+/- 50 feet) or 300+ meters
Resolution: 480p or higher
Recording duration: t>=2 minutes
Durability: Sustain 7G acceleration force (excluding the Jerk)
Frames: 30+ fps
Operating frequency: 5GHz > 2.4GHz
Other specs: NTSC preferred

Does anyone know of any cameras that meet these specifications or point me in the right direction? I have looked at numerous spycam websites and RC Toy sites and still cannot find anything that meets these specs. My next solution would be to use create my own by buying parts through websites (sparkfun, adafruit) but I do not know enough about video equipment and compatibility. Any helpful information would be much appreciated.


To meet your specs you may need to expect to spend significant $$$. Are the tx/rx locations fixed or moble? Below are some can companys that have been around a while you can study for your equipment.

Another question:

What is the best way to have a RCA video video output converted and connected to this lcd screen? https://www.adafruit.com/products/358

Use a processor with significantly more power than an arduino. I suggest an ARM chip with a built in LCD driver like the type used in mobile phones. It is not a simple project to do, although you might think it sounds simple.

Grumpy Mike, correct me if I am wrong but my next options if I choose not to go the ARM processor would be to use a digital output camera with my thread's stated specifications and use that in junction with the screen from adafruit or to find a pre-fabricated 1.8 inch (or 2 inch) lcd screen with a built in RCA to digital conversion.

I do not think you will find a digital camera that has an output suitable for feeding directly into an LCD, the two use very different sorts of signals.

What type of communication does the lcd use? I thought cameras had outputs of either analog or digital with monitors adhering to one or the other.

The LCD uses a parall interface of 18 or so signals. A digital camara can output data in a number of diffrent formats but not parallel RGB like an LCD.

Do the two screens have a similar communication connection? If not, what are the different types of "raw" LCD connections that are similar to the ones provided in the links below? Would the controller in the 2nd link be able to work with the adafruit lcd screen? http://www.adafruit.com/products/618 http://purdyelectronics.com/pdf/ANDpSi020TD-LED-KIT.pdf

How would I use or convert the two products in the link below? Are they even compatible or would I still be left with the same problem of needing a microprocessor/controller? http://www.sparkfun.com/products/8826 http://www.adafruit.com/products/358

Grumpy_Mike: The LCD uses a parall interface of 18 or so signals. A digital camara can output data in a number of diffrent formats but not parallel RGB like an LCD.

In conjunction with my previous post and your post: Does this apply to all LCD's to have 18 (or so signals) or are they varying to some degree? If they vary, how are they categorized?

If they vary, how are they categorized?

They are not.

LCDs have virtually no standards associated with them. There are no names for interface types, they use different signals and timing, they are virtually all propitiatory. That is why your questions have no answers. Some processor chips like the ARM chips used in mobile phones have configurable LCD drivers to allow a large number of different types of LCD to be accommodated but not all types. Most LCDs are obsolete in 6 months, you can get industrial ones that have a longer life but not over 3 years. Then the remaining stocks are dumped on the surplus market and when they are gone they are gone.

That will definitely limit my receiving end of the project.

As far as NTSC cameras with output wires of red (power), black (ground), yellow (video), is this the same for all NTSC cameras with just three wires with a similar configuration of power, ground and video? Is a composite camera always an NTSC camera? If not, is an NTSC always a composite camera? I see the two often together when I am searching for the cameras. Either way can a composite camera have more than three wires for only the power, ground and video (no audio)?

Reference for later to read and ask questions (I'm on lunch break at work):

How to write video from RCA to micro SD using Arduino? I may be over my head and yet that is another project. I am probably jumping the gun on this. http://www.ladyada.net/products/microsd/

How to write video from RCA to micro SD using Arduino?

Simple you can't. The arduino is not fast enough and does not have enough memory.

Is a composite camera always an NTSC camera?

No there are PAL composite outputs as well.

is this the same for all NTSC cameras with just three wires with a similar configuration of power, ground and video?

Nearly, this would apply if it were a colour camera, if it's black and white it aint NTSC ( it stands for Never Twice the Same Colour :) )

can a composite camera have more than three wires

The word composite gives the clue, the other sort you can have is component with a separate signal for R, G, B & sync, there is also S-video plus a lot more, see:- http://en.wikipedia.org/wiki/List_of_display_interfaces

Thanks Mr. Grumpy. You have been very helpful. That wiki-site came in handy.

I'd rather ask a stupid question here than at the online retailers:

Can the lcd + controller still operate without any keypad connected? Basically no inputs to the controller other than the video feed telling it what to do with no OSD menu pop ups. http://www.purdyelectronics.com/pdf/ANDpSi020TD-LED-KIT.pdf

While that controller and display looks like it might do what you want I would advise caution. There is very little information about the controller, especially the inputs to it. Try and find out more information before parting with cash. There is not information in the sheet to answer your question.

Okay, I was trying to limit myself to a mini screen. I’m considering other options now. What kind of converter and/or cable would I need if I were to record and stream the wireless video on a laptop? The wireless receiver would still have the RCA output.

I’m currently waiting for a response from the company selling the mini 1.8" screen. If this route does not seem likely, I will brainstorm more ideas on top of the laptop one.

The reason I was wanting to use a 1.8" lcd or 2" was because I have a very old game console sitting in my garage and decided to reverse-engineer it. I de-soldered the two keypads on it and mapped out all the buttons through analog voltage readings. Basically what I had in mind was to create a water bottle rocket, with a live feed in the tube, use the sub assault as a controller to launch the rocket from a distance and watch the action on-board. It is a bunch of mini-projects combined into one. The lcd, transmitter/receiver, camera, xbee wireless controller are all sub projects. If space allows it, I utilize all the buttons on the game console to have a video feed switch between two cameras which I have not decided if I want two cameras in the rocket or one hacked onto the game console and one in the rocket.

I will more than likely have to attach the wireless receiver externally on the console. It is the lcd I was hoping would add a wow factor to my project as well as provide a dark space to easily see what is going on and also record if possible.

to record and stream the wireless video on a laptop?

Do you mean onto a laptop rather than on a laptop? You need a video adaptor, the sort that you use to transfer video tape onto a computer.

Look at security transmitters for video transmitters. Also have a look at model rocket websites it is the sort of thing they do all the time.

Not sure if I understand your question. I want to watch what is being recorded on the camera that is on the bottle rocket in real-time. Real-time as in when the rocket is 50 feet in the air after 1 second, I want to see this with my own eyes speculating the rocket from a distance as well as seeing what it looks like from what the camera on the bottle rocket that is sending at the same time. I understand that there may be a slight delay in this transmission but I want it to be near the same time (real time, live, stream, or any non-english words that can express what I am envisioning). So I want to watch the bottle rocket move by watching through an lcd screen, laptop or other portable screen and also quickly glance at the rocket with my own eyes as it moves with respect to time. Does this answer your question?

Thanks, I will have to look into security transmitters. I have looked through numerous rocket and remote control hobby sites and forums and a lot of hobbyists use the eye goggles which are fairly pricey. I would like to constrain my project to the mini lcd.

I believe I found a video adapter on NewEgg called the Dazzle: http://www.newegg.com/Product/Product.aspx?Item=N82E16815144044

Your best be is to do google searches like below and visit model rocket and rc airplane sites. In years past I've seen x-10 wireless video cameras pit in model rockets. Some of the DIY drone sites should also have cam discussion areas.
