Part 1

Why?

Shooting long range target is a lot of fun, but it`s a pain to drive down to the target to see the results.
Unless your shooting at a range where you have target service(Highpower) or using steel, seeing holes trought your optic past 400yds is tricky.

Many solutions are available if you have the funds to persue them, but if your like me(cheap), you want a solution that does not break the bank.

My solution is not exactly cheap, but is versatile enought to justify the money spent.


The problem;

I shoot at a military range where we used to have access to a target monitoring system in which the sonic boom of the bullet passing trought the target would be detected and display on a screen with 1 mm precision.

We got spoiled with this system for a couple of years and budget cuts terminated our access to the system.

I wanted a system that would allow multiple users to monitor they`re targets.
The system had to be affordable, simple, easy to pack/unpack and easy to use.

The articles I read on a couple of forums where interesting, but did not satisfied me since the equipment where limited to that task only.

I was looking for a system that could use equipment that I already have or could use for other things.

The WiFi technology is everywere, I am sure that most of you use it at work and probably at home.
Therefore, you already have and are familliar with the equipment.

Also, since WiFi is mainly design for computers.
The possibilty are endless, hardware,software,etc.

I bought an Ipod Touch for many reasons, but having a ballistic software in a compact package was very interesting.
The Ipod using the WiFi technology was a bonus.

Again, I wanted something that all my buddies could use and many already had laptops or planniing to buy a Palm/Ipod.



PART 2

What you need

Display;
Laptop, IPod, Palm, anything that will receive and display a WiFi image.
Use whatever you have now. (I will be referring to the IPod in the following text, but all info applies to other display except in regards of software,
web browser being the exception)

Camera;
They are called network camera and are distinctive by there Ethernet connector(RJ-45) and WiFi antenna.
I suggest to pick a camera from the list below as they are compatible with Mobiscope software live feed video(IPod).
http://www.mobiscope.com/cameras/


To transmit over long distance, you will need a signal booster and antenna.

Antenna;
I strongly suggest you go with a Yagi or Patch antenna. They are directional antenna that will transmit the signal mostly towards your position(20 degrees).
An Omni antenna will transmit 360 degrees, therefore less range for the same transmission power

Signal booster;
Your camera will transmit the signal up to about 20'.
You need to boost that signal to reach your shooting position and IPod.

I started with a booster that attach itself directly into the antenna output of the camera and up to the Patch antenna. I had no problems and work perfectly at 600 meters.
I changed the booster because I wanted a model that would be able to handle multiple cameras.
More on this later.....


So, you have your IPod,camera, booster and antenna.
Once you switch everything on, you'll need to set your IPod to the WiFi network of the camera in the "Settings" Apps.

Operating with a web browser
Open the Safari web browser and write the IP address of the camera.
A picture from the camera will appear. You will need to refresh the address every-time you want to update the picture.
Bookmarking your camera address makes the process easier.

Operating with Mobiscope
Go to "my camera" press "+" and write the camera IP address and select the model and brand of the camera in the selection"add camera model"
Some camera might have a "user" and "password" protocol to fill up before you can access the feed.
Don't worry about it, this info comes in the camera's manuel and you'll need to enter it only once in the Mobiscope program.

Operating with a laptop
The software provide with the camera will allow you to have a live feed video.



Multiple cameras and displays transmission.

My primary goal was to find a system that would allow multiple users to monitor they're targets with the same base of transmission.
The other design I read about where limited to one or a few users, the WiFi system can handle multiple cameras and displays.
That is where you can save $$$$$.

Our shooting club agreed on paying for the antenna, signal booster, router(2) and switch(16 port), cost was less than 1 000$ ca.

Any member who wants to use the system has to bring his camera, ethernet cable and IPod. 110v outlets are provided.

How it works.

Shooters place they're camera in front of the target, run the ethernet cable from the camera to the switch.

The person in charge of the system plugs in the switch to the router and antenna.
Another router, called a repeater, is on the shooting line.
This router will receive the info from the antenna down range and retransmit to the IPods.


The tricky part is done by our WiFi supplier who configured the routers to communicate together before we deployed them.
This part is beyond my expertise and you will have to get the info from your supplier.
Actually, I would make it a condition for sale, that all components are configured before buying them.
The configuration is done once and can be downloaded to your hard drive in case it needs to be reloaded.

Cost;

1 user = 650$(detail below)
IPod = 250$
Camera = 200$
Signal booster for 1 camera = 100$
Antenna = 100$

Multiple user add 450$(detail below)
Router repeater = 150$
Switch = 100$
Signal booster for multiple cam = 300$

PS; A BIG THANKS FOR ARROWHEAD FOR ALL THE WORK HE PUT IN TO THIS SYSTEM.
HE MADE THS POSSIBLE!
 
you suck. seriously.

ok you don't. that's f**king awesome dude!!!!!!!!!!!! I wish we had something like that at Volkes. But 24 cameras? could that be handled?

do you not need to boost your laptop as well? or not, because it's only receiving not sending anything to the camera?

side question, do these boosters work good in a house if you just want to increase your wifi range for internet surfing in a room far away from your router?

and also, what's the deal with those target frames? what are the things folded down to the side? backers of some sort? pop ups? I wonder if that's what they are intending to install at Volkes?
 
Here are some more pictures of the prototype of the single shooter system

All the system fits in a mobile tool box


Power pack inside tool box for the camera and booster


The antenna can be mounted directly on the tool box. At the time I used an "omni" antena it gave me signal up to 850y, past that the signal fades rapidly. If you use a YAGI or PATCH antena like ssgp2's you should in theorie have a range of 1600-1700y but we have not tested it yet



IP camera with signal booster


Router in the vehicule to receive and distribute the signal to the ipods/laptops (there is a magnetic antenna on the top of the truck) The reason to have this router on the firering line is because if you shoot in prone position your ipod/laptop will have a hard time receiving to signal because you are to close to the ground. Any domestic router can do the job...


Image of the target on the ipod. The ipod is in an arm band for jogging on my forearm, this way its very easy to access it and at the same time its protected from de rain

For now we have a 16 port switch (1 port for antena and 15 others for camera) we went up to 10 cameras on the system at the same time without any problem but the be honest I have no idea if you could do it with 24 cameras at the same time., but if you can find a 25+ port switch I dont see any reason why it would not work...

No need to boost the laptop, the router in the vehicule does the job

Never tried to boost the internet signal but yes it would work

The target frame are the military electronic target system, the targets folds on the sides when not in fonction

You don't need a 25+ port switch just get two 16 port switches and connect them together.

Only problem I can see is 802.11Gs bandwidth. Since a such a long distance you probably are not getting the G speeds anyways that limits your bandwidth even more. So if you have 24 cameras sending out data at the same time, depending on the resolution of the camera picture you might get extreme lag. However since all you really need is just a simple picture it probably shouldn't be a problem if you lower the settings as much as possible.
 
Once you get to a point where your system does not perform well because of the number of user.
All you have to do, is buy another antenna,router,booster.

If you limit the system at 10 user, that is 60$/each + your IPod/laptop.
Compare to your membership card, that is cheap!


The nice thing about the live video feed, is that you dont have to refresh the pics every time you shoot
 
Indeed it's worth the money spent. It work well and it's fairly easy to use.
Thumbs up guys.
 
I'd pay someone to install a 12 camera system at my club, then sell special membership packages to allow people to use it. anyone want to do a quote
 
this is a cool idea , i have the same setup when i go huting/targets , but i use satellite's to send the pic's to my notebok/phone


ok. 3g wireless card on my notebook , and have a cam pluged into the computer or wireless ip cam.

then all i do is log on the the ip cams ip/web site and view my pic's/videos on a iphone

this way i can be where ever i want.


take a look at this may be a beter idea , 3g wireless ip cam.

Hi Slavex, if you want I can kit put a kit together for you, all you would have to do is plug it in when you receive it

pm me if your interested :)
 
Can you break down the cost of your system?
Cost of camera
Cost of the Cell phone contract with this service.....

These are all great ideas.
One thing to keep in mind is how large of a target you want to view with the camera and if you are going to be able to see the bullet holes.
If you are using a shoot N see target or shooting a painted gong this likely won't be a problem.
If you are trying to record shots taken on large paper targets it's going to be harder to see the hits. With a 640x480 camera sensor it will be tough to make out hits on anything larger than about a 4' wide 3' tall target. There just isn't enough pixels per inch of target to give you a sharp enough image to make out the bullet holes which might only be 1/4" square.
Of course higher resolution cameras are available, but then they are also more $$$.
 
did you consider using a swtich at the target line, and running cat 5 / 6 to the firing line, with one router at the firing line. no boosters and antenas to deal with.

cat 5/6 might max out at ~200 meters though.
 
We have a reasonably long range computer network bridge setup using Netgear access points. The antennas are about 1' x 1' (18 dbi and $50 on eBay) and the Netgear mid/high end access points running at Super G speed, 108 Mb/s. Retail price for each access point is about CAN $180 but we got them on eBay for about $25 to $40

We are at 4 to 500m without any problems but could easily stretch it by putting amplifiers on the transmitters and get a couple km out of the setup.

There are lots of high resolution cameras coming onto the market really cheap. We just got one to make up a custom inspection rig and it was $75, but not an IP camera. Colour resolution is 420 TV lines, Sony CCD camera and lenses are interchangeable.

Here is a good workable setup for a camera system

Outdoor IP camera with high resolution Sony CCD $300.
8 port router at target end $50 with cameras hard wired into it.
Netgear access point as transmitter (WG-102)- eBay $50
2 antennas ebay $150
1 Netgear 2 channel access point/transmitter (WG-302) eBay $50

At the line end, your laptop, wireless device, etc would simply connect to the WG-302 which is the receiver and also the DHCP router and you have multiple access to the cameras.

If you have power anywhere near your targets, you can go with conventional cameras connected to a computer at the target end to manage the cameras, and then wireless to the line, as it would be a much cheaper, and simpler system.

Or you can use conventional cameras and a USB converter connected to a laptop. A 4 camera port to USB adapter is about $75 and any cheap laptop will do as a controller at the target end. Can all be battery powered.

dumb question: isn't the camera vulnerable or is it somehow protected from the shooters?

In our case in Farnham we're limited to 600 meters. At that distance if the camera is on the ground some 3 feets under the bull the risk is fairly low to none unless you did'nt check your turrets or the weather is really nut.
However if you're not as confident in your abilities it would'nt be much trouble to put some protection in front.

OK, But...

That sounds fantastic.... but.

Excuse me if I missed this in the explanations but.
Where I'd use this I don't think they,ll want an ant. sticking up above ground.
(people in the butts)
And
there is no sourse of Hydro.


Will it work with the ant. below ground out to 1000 yds ?
Will it work off of batteries?
Will it work for just me ?
