Q&A:

Landen asked How can I operate and record video from a DSLR camera 100% from a PC?

I am part of the aquatics booster club at a high school and want to mount a high quality video camera (and microphone) onto a fixed position near the pool at a high school to record water polo games. I need the video to be shot in 1080p with decent sound (able to hear whistles and call-outs). The games will be played in the daytime, and should be recorded directly onto a computer hard drive either in a nearby office, or a laptop used by the coaches (who will sit and coach in the pool area). The plan so far is to mount this rig and it’s weather proof shelter to a light pole near the pool.
The critical points are:
1.) Camera mounted high up where no one has to touch it to operate it. Everything including turning it on and off has to be done from a computer nearby.
2.) Quality video and decent audio from at least 40 feet away.
3.) No significant operating skills required. No one wants to record video or sound manually on the ground. No one will be willing to edit video or audio or sync anything. All we want to do is burn it to a DVD and be done after every game.
4.) Our budget is $10,000, though we by no means have to spend all of it. If we don’t spend it, aquatics can use it for something in following years.

Please help. Our team trains very hard and is very competitive, and we want this to last for years to come and provide video for training and for team viewing purposes. Do we need to hire a professional? Can we pay professionals to install pro-sumer equipment?

And got the following answer:

I agree with “airdogspace2” and suggest you get this done professionally.

1) Most dSLRs will overheat and shut down afer about 20 minutes of recording video. Your games probably last longer. than that.

2) Additional requirements: Power. We presume the camera is never dimounted from the pole. There are no batteries that last forever. Run power.

3) Questions: From your description, zoom is not required. Also, panning the camera up/down; left right is not required – if this is required then a whole different set of things happen.

4) Assuming the video is burned to a DVD, as which format? If playable in a computer – as a MOV, MP4 or AVI file… or playable in any regular DVD player? If in a regular DVD player, they can only deal with standard definition video, so the requirement to record in 1080p is unnecessary. If to playback in a computer as a MOV, MP4 or AVI file in high definition a single layer DVD holds only 4.7 gig of data while a double layer DVD holds 8.5 gig of data. I just did a render of a 00:03:38.00 (0 hours: 3 minutes: 38 seconds. 0 frames) of a high quality, 1920x1080p/30 edited video. It was 2.6 gig. Assuming a water polo match is 60 minutes, no one wants to edit, for round numbers, just multiply the 03:38 x 20 – rounding… we also do 2.5 gig x 20 = 50 gig of low compression, high quality video. Then it needs to be compressed. This same 2.6 gig file took about 30 minutes to compress into an MP4 suitable for use on a personal media player to about 130 meg – so that’s doable… If only 1 DVD is needed, then 4 minutes to insert a disc and burn remove the disc, mark it…

There’s more for video, but we’ll hold here for a moment… Now for audio…

If you were to position yourself where a single mic would be placed and not move, chances are pretty good you would not be able to hear call outs “from 40 feet away” – whistles you probably could… To “hear” like that over the area of a pool would need several mics placed closer to the activity – not the camera’s built-in mic – and a parabolic mic is too directional. If you have ever watched a televised pro or college basketball game, there are about 30 mics placed up and down the court and an audio person changes the gain on the mics closest to the action – and is very actively involved making adjustments. You don’t need this – but perhaps 6 shotgun mics – 3 on each side of the pool, perhaps no more than about 20 feet way mounted on a pole pointed at the pool.

Perhaps the high school has an AV club or computer club (with an emphasis on video capture/editing) that is willing to team up and provide the camera work, editing and such – even do the video providing they get to use your equipment to capture the water polo matches…

Another option is to use high quality commercial grade security cameras and high end video server/recording gear. The video burn will take a while, but the cameras can be outdoor rated and you could use the cameras for other things (security device). If go this route, $10k may not be enough.

Ice asked What size solar panel would be needed to opperate a small device needing 5 volts and 2 amps ?…..?

What size solar panel would be needed to operate a small device needing 2 amps. to run for a short times ….?

I asked this question and did get a good answer , so i thought I would be more detailed about what I am trying to do and get a final answer before I make my purchase of a panel kit. A security camera that needs 5 volts and 2 amps. to run. that is connected to a 400 watt 8 amp. power inverter. That would be attached to a rechargeable sealed 18 ah 12 volt battery. Note : I already have camera, inverter and the battery. The camera would only be on drawing power when viewing being it can be remotely turned off and on. Panel would have average sun light during the day – (est. 6-8 hours daily). So with the detailed info. : Need 5 volts 2 amps. to run my wireless camera . I have a 12 volt 18 ah sealed rechargeable battery and a 400 watt 8 amp. inverter. Camera only on a few times daily for short periods to view.
In simple terms ( new to solar stuff )…. what size solar panel in watts / amps is needed to keep battery charged up and ready when needed ? Am I correct that amp output of panel could be slightly less then the 2 amps.that’s needed to run camera being it would get the power ( the 2 amps) from battery and then panel would recharge the battery back up to full power when not on and drawing any power ?. My research tells me a 40 watt , 3 amp. panel would work ?. Thank you in advance for any help and advice. Please keep simple if possible !
Thanks for the help and advice. As I stated I already have the 12 volt battery, the inverter, and the camera.That is what I will use. It is a ac camera with a standard 110 plug to be plugged into a wall outlet. Being this is going to be used at a remote site and no power I need to use a converter.
Looking for answer based on info. I provided above. Will say the camera would be on under 3 hours a day if that helps. I just want to buy a panel with converter that will work with what I have. Thanks

And got the following answer:

you need to compute the watt hours used per day . it takes 24watts(12v times 2a) say for 0.5 hours total . that would be 12 watt hours . allowing the battery as 50% efficient so thats 24watt hours input needed. but the inverter has losses too so youre looking at say 32watt hours . A rule of thumb is that in europe and northeast US you can reckon on about 3 times peak panel output per day . so you would need a 11 watt panel to generate 32 watt hours . looked at in amps 11 watts is about 1 amp peak from the panel.
you can adjust these ball park figures depending on your estimate of the total hours that the camera runs.
I agree with Steve that a 6volt battery and panel would be better and eliminate the inverter . his approach is the correct engineering way and needs less than half the power and therefore half the size of panel for a 12 volt system . I know you want to use the parts you have so using my calculations above you have said 3hours running so i need to multiply my above calculation by 6 = 66 watt panel.
in most of US you get a higher sun level so you probably would be able to use around 45 watts panel.

Mazi asked How can I find a conbination of Solar Powered Street Light and Security Camera as a combo and at what Price?

I am working on a project that will supply Solar powered Street Light to a State in which Security Cameras will also be installed at select points on certain poles. I want to know what this will cost with the following requirements for the Street Light: 40 watts LED for the light source and 80-120 watts for the panel with battery and controller all inclusive.

And got the following answer:

A forty watt street light isn’t much of a light, even if it uses LED’s — which at present are about as efficient as a high pressure sodium lamp. Solar power runs about $10 a watt; you need 40 watts for the light, plus 120 x 2 = 240 watts for the camera (presuming that it operates continuously), which you have to double because of the cosine rule (sun doesn’t shine directly on the panel, so average power is half of peak) for a total of 560 watts solar cell capacity. That’s $5600 — assuming that it doesn’t rain.

AlanIAM asked Help finding a good set of security cameras for community entrance without electricity?

I need advice on security cameras. We have two entrances to our Colorado mountain community neither of which has electricity. We want to post cameras at both entrances and maybe one or two other locations. I am thinking we’d have to go with battery operated cameras and even better if the cameras allow the batteries to be solar recharged. To save us having to climb trees, removing memory cards, etc., we would like cameras we could drive next to with a laptop in the vehicle, download the pictures, delete the pictures from the camera, be on our way. Would be even better if we could transmit the pictures via the internet but nothing electronic out there, like a router, and transmitting pictures via satellite would like be too expensive, I think. Might someone here know of a good camera or a kit that would fit this need? Our budget is $500 max and that will be a bit of a stretch.

And got the following answer:

Check out wildlife/trail cameras with GSM connectivity – if you’ve got some sort of cellphone reception in that area.
Can’t recommend any brands or even websites, though. Most of them seem to come from China anyway.
What I can see from here, the prices for the GSM models seem a bit overrated, though (around 350$) – a German supermarket chain is regularly selling the cheapest no-GSM-model for 99 €.

If you don’t have GSM connectivity in that area, you might check if an Eye fi card works in the cameras that might be suitable for you: http://www.eye.fi, those look like ordinary SD cards, but provide WiFi connection in addition.

Oh, and perhaps run a cord down to a battery compartment at ground level. Saves you climbing that tree to change batteries unless some a**hole rips out said battery compartment (won’t do them any good with the batteries inside the camera still operational…)
