If you dont mind me asking , Did you find a more reasonably priced camera system that would work out to 1000 yds , or even 600 ?

I read your posts regarding the the test of such a system and noted you mentioned wanting to look for more economical components . Was hoping you had found some .

Thanks for your time ,

Jim,

I'm sorry to say that I have not found a package of equipment that will provided a reliable signal strength hence useful image at a price I'm willing to pay. The key problem is the transmitter and antennas. Even with very directional high gain antennas on both ends you still need a combination of frequency and transmitter power that puts you into FCC licensed services.

I'm still looking and others have mentioned equipment on this and other forums so you might try a search. Maybe one of the others that have tried with actual range success will post here.

Hello,
I am a security contractor in California and do quite a few CCTV systems.
Is the system you are looking for for your range or something you can move around?
My main question is does it need to be portable or can it be hard wired. If you want wireless it will be fairly expensive. Wired can be pretty cheap.
Send me the details of your location and what you are trying to accomplish and I will help you.
Thanks.

Steve

have you checked out some of the better RC airplane stuff ? I've heard that their Trans/Rec. will range well over a mile

Fred ,

Thanks for your reply . I will keep checking other places and should I find something that seems to fill the bill I will post here .

Steve, thanks for your offer . Primary interest is in a portable wireless system that will allow bullet holes to be visible out to 1000 yds .

jimm,

I'm not trying to be a wet blanket about the wireless video idea but every body interested needs to be cognizant of the interference issues and at higher power and or with directional antennas with the regulatory authority and responsibility of the FCC.

The purpose of the FCC regulations is to insure that persons operating radio frequency emitting equipment and particularly transmitters are doing so in a manner does not interfere with the lawful use of those frequencies by others.

The so-called unlicensed bands do not require the owner/operator to be licensed only if the equipment is limited to very low output power with low efficiency antennas so as not to produce significant signal strengths at very long distances. For example, baby monitors,audio and/or video) are limited in output power and antenna efficiency so that the range is limited to a single house on a city sized lot. That way millions of units on the same or 4 adjacent frequencies can be operated with little to no mutual interference.

Licensed bands require the operator to be responsible for preventing harmful interference with other licensed and unlicensed services. Note that licensed operators are subject to not only loss of license but fines and/or imprisonment for operating outside the terms of the license or causing interference with other services.

For example, the RC equipment CJ6 mentioned does include some fairly long range video capability. However, the assigned frequencies and power output/antennas are permitted only for that use and for "intermittent brief use that does not interfere with any other regulated service". Further, even that use does actually require the operator to pay a fee and obtain a license "before first use" for RC airplane use only. This is similar to the GRS radio service,long range hand held radios popular with hunters and hikers) that while equipment is readily available on line or retail, a license "before first use" is still required.

I made a written request to the FCC to determine which service would be applicable to our use and what license fees and restrictions would be required. That was over 90 days ago and I have not had a reply as yet.

Fred ,

Thanks again , I appreciate the cautionary note . I am aware of the constraints and still hope to find something that wil work within the narrow limits . The hurdle that I see the most difficult to overcome is the limited number of frequencies that are available. I also appreciate the fact that you are trying to resolve some of the issues with the FCC.

Cj6 , sorry I did not address your input , was short on " keyboard time " and am a " two pecker",, no joking on this now ! ) so that really limits the amount of time I have to post . At any rate , yes ! , I am aware of the advances made in the rc field as I was building 1/4 scale models with 50cc chainsaw enges a long time ago . The new 2.4 technology is very encouraging as it allows a number of users to be flying at the same time without " frequency " constraints .

At some point in time this will be resolved .................just wish it was now .
