11. I have seen Video Transmitters priced from $100 to over $15,000. What are the differences?

Answer #11. For professional applications you want reliability, stability, a quality picture, and good sound. The cheap “Video Senders” you may have seen usually have poor picture quality, may not pass a color signal and will not stay tuned since they are not crystal controlled. They also use AM transmission for cost reasons. Just as FM radio sounds better than AM, FM Video has a 15 dB advantage in signal reception over AM Video. It is also immune to interference from many more sources than AM. Even some of the wireless video systems selling for $2000-5000 use AM. Avoid all non-crystal controlled and all AM Video systems. The Professional video transmitters used by broadcasters for short range transmission cost up to $25,000 and are all FM. DPL-Surveillance-Equipment is using clever design and the latest highly integrated, technology to give you virtually this level of performance for a fraction of the price.

12. What frequencies should I use?

Answer #12. If you do not fit in an FCC regulated service such as broadcast, public utility, etc., or, you don’t want the hassle and expense of applying for a license, then you currently have two choices. Under FCC part 15, low powered video transmission is allowed between 902-928 MHz and 2.4-2.483 GHz. The 900 MHz band will yield better range than the 2.4 GHz band and has fewer dropouts due to multipath reception problems. The 2.4 GHz is now the standard band for Wireless computer networks (WLANs) and also Microwave ovens.

13. Do I need to worry if a Video Transmitter and Receiver are FCC approved?

Answer #13. Yes! You and /or your customer may be liable for severe penalties and fines if caught. NOTE: If you see a Video transmitter for sale that can be received by an ordinary TV set or tuner without its own receiver, it is not FCC approved.

14. What distance or range can I expect with a Video Transmission system?

Answer #14. Unfortunately it depends on a huge number of variables such as transmit power, antenna type, building construction, height above ground and surroundings. Inside, metal shelves, filing cabinets and other metallic objects may greatly reduce the range. INSIDE: You can expect a range of between 50 to 200 ft. inside a modern steel building, depending on the antenna type and location. You may have better results in brick, wood and other non-metallic buildings. The number of floors or walls the signal will penetrate is dependent on their composition and antenna type and placement. OUTSIDE: DPL-Surveillance-Equipment has tested its transmitter and found that in an urban area, about 1000 ft (328 m) is realistic. In a more rural setting, a one mile (1.6 km) range is reasonable. Our advice is purchase our system and see if it works for you. Call us at (800) 548-2939 Access Code 01 and we will assist you with the set-up assistance you may need.
