That's old news. Where would we be without a world interested in 'firsts' and in 'records'? We'd lose our competitive spirit. We'd become an amorphous mass of undifferentiated consumers. The Olympics; the NFL and Nascar would become irrelevant. Watersheds in history would be explained as collective endeavours. Individual initiative and that never-say-die 'can-do' frontier-like attitude would give way to widespread social apathy. Collective effort? Sounds like communism. So no thanks.

In any competition of 'firsts', the US remains adamant about being ‘first over the line.’ The word 'tele-vision' implies a form of transmission. The recent Farnsworth endorsement appears to be an attempt to sideline Baird; just like Tsutomu Nakamura’s contribution to CMOS seems to have been overwritten by Eric Fossum. America can then falsely claim to have ‘invented’ two critical technologies. When Baird was transmitting recognisable images before no less an institution than the Royal Society, Farnsworth was transmitting a glowing blob. By 1927, Bell Laboratories used Farnsworth’s method to demonstrate television to the Americans. The stunt required the support of a thousand technicians to send a signal between Washington and New York (200 miles). Less than two months later, Baird broadcast signals over twice that distance from London to Glasgow with only seven men. Then, in 1928, he really showed off when he made the first television broadcast across the Pond (the Atlantic). History is written by the victors and numbers count: US population: 312 million Scotland’s population: 5 million

Found a reference to Farnworth and Baird in Wikipedia: In 1932, while in England to raise money for his legal battles with RCA, Farnsworth met with John Logie Baird, a Scottish inventor who had given the world first public demonstration of a working television system in London in 1926, using mechanical imaging systems, and who was seeking to develop electronic television receivers. Baird demonstrated his mechanical system for Farnsworth, and explained "the superiority of his system". But after watching several minutes of Farnsworth's version, "He advanced slowly, as if hypnotized, until he was standing directly before it, He stood there for some time; he turned without a word and left" (How would any academic writer know this? It reads more like a B-novel.) The footnote given by Wikipedia is Donald G. Godfrey. Godfrey is a relentless promoter of the Mormon Church. Philo Farnsworth was a Mormon. Donald Godfrey is not an impartial academic writer or researcher.

Any footnotes on the Baird-Farnsworth connection? Let's not forget Vladimir Zworykin from RCA, who invented the first CRT (cathode ray tube) in 1928 which was later used in TV. Then there's Nikola Tesla who invented the electric alternator in 1884.

Not suggesting that he changes other domes to Kalatel, Sensomatic or Molynx-D. Trying to establish why the CCDA1435 works on the CKA4820 but not on the 4NSYS. If it worked on another language, it would prove that the DVR can operate the CCDA1435. The only two remaining variables are the CCDA1435 on Pelco D and the DVR RS485 signal.

I sincerely hope that these changes work and you report that it is operating normally tomorrow. If not, and if you have all the time in the world, you could verify a couple of things. These are all last ditch measures. You could change the DVR settings to Kalatel, Sensomatic or Molynx-D to see if you could get the CCDA1435 to function at all with the DVR. All very time consuming work certainly. Plus, I have seen some evidence of firmware/software corruption so that may be a possibility. Or, you could bite the bullet entirely and pull the FCBEX480 (I am guessing that is this model) out of the Siemens dome and stick it into a generic dome for maybe $200 or less. Anyway, fingers crossed on the baud and address changes. Good luck.

Pelco also offer a Pressurized Spectra Speed Dome filled with nitrogen. This unit has the distinct advantage of internal alarmed sensors which warn of changes to pressure, temperature and internal moisture beyond defined limits. This unit is rated at IP67 which is well above the standard Spectra's IP66 rating. The minimum operating temperature is relatively unchanged at -51.11°C Excerpt from Nitrogen Pressurized Spectra:

Blast freezers will only reach as low as negative 60°C. Most claim to reach only as low as negative 30°C or negative 40°C. The coldest medical/lab/research freezers are hard pressed to reach negative 150°C. Beyond negative 100°C is rare. Arctic conditions bottom out at negative 89.2 °C (− 128.6 °F) which is the world’s coldest recorded temperature taken at the Soviet Vostok Station in Antarctica in 1983. At -150ºC we approach the realm of cryogenics. For a standard blast freezer, at around -60°C to around -30°C you may be able to use the Pelco IV which Schneider claims can handle -51°C. The problem of cold air moving over the dome would worsen matters. A position protected from the air blast would be optimal. Axis tout an arctic speed dome which they claim can operate at a sustained -40°C. (I don't recall the fine print regarding wind speeds.) This is still 11°Celcius shy of Pelco's claimed minimum sustained operating temperature. In other words, you may get away with a standard Pelco dome. The excerpt below details Pelco's claim for the Spectra IV Environmental Pendant:

Lancillotto, the CCDA1435 uses a RS485 Termination Switch on the rear of the dome drive - next to and just above the BNC input. See diagram and my arrow below. Please take a look at it on your CCDA1435 This switch should be set to the ON POSITION.

That is an outdoor IR bullet with an IP66 rating. The IP66 means you can spray it with a garden hose without a problem. This camera was not intended for an enclosure.

It strikes me as a marketing ploy to say indoor/outdoor. Obviously if a camera can work outdoors it can work indoors. (There was a chap from Arizona a while back who was also lamenting about heat shortening the life of his cameras.) If your weather is not extreme; i.e. very hot or very cold, then you have two fewer problems to face. Otherwise, enclosures, recommended box cameras and auto-irises are very reliable and robust.

Tommie. you are a bloodly little liar. My first system was up and running well before I had ever heard of this forum. The Pelco protocol conversation was in cctv history i.e. what person was behind Pelco's push to dominate the market. That historical question has never been answered - certainly not by you. N.B. You destroy threads with your never-endling nonsense. You have spent most of this thread whining at me with stupid comments rather than looking at the issue.

Very funny joke. It has never occured to me but, yes, surely there have been folk who have installed perfectly good, expensive cameras outdoors without any enclosures. They probably just didn't think through what they were doing. Sometimes you do see a box camera under a porch without an enclosure. You might just get away with that, though I'd still use an enclosure even in a protected outside position. Better safe than sorry.

Supernaut, you don't yet know how good the advice is that you have gotten here. These recommendations have saved you a lot of money, time and headaches. These items are the highest bang for your buck that you are ever going to find. (And you could easily spend a lot more money and get a less effective solution.) So, if you are serious about dealing with that neighbour, get on the phone and order what has been recommended. Time is a wasting. Also, just buy generic BNC cables. They are adequate for your needs and easy to install. What about a Power Supply?

1. In temperate climates, the moisture and condensation is not a problem.2. Heat can be a serious problem in warmer locations. It is then a good idea to use enclosures with separate shrouds to take the direct sunlight off the body of the enclosure. 3. Not all indoor box cameras are suited to outdoor installations. Check the manufacturer's recommended maximum and minimum operating temperates before purchase. Even with an enclosure, you may still have to be conscious of extreme heat but not so much extreme cold because the better enclosures can come with heaters. 4. Obviously all box cameras must be placed in housings when installed outdoors. Box cameras have zero weatherproofing.
