Have security tv camera 47546 with a female phone jack plug on end of wire you dont have the other end how could you find out which wire is what to be able to hook up?

From the camera Black <-----------> White From the TV hookup

From the camera Green <----------> Blue From the TV hookup

From the camera Yellow <---------> Yellow From the TV hookup

From the camera Red <------------> Orange From the TV hookup

I just used this connection for my cameras when the weather trashed the phone jack connection outside. I cut out the phone jack connection then I made the connections with solder.

The above is useless here is what you want:

White=ground

Yellow=Audio Tip

Blue=Video Tip

Orange=V+ (7.5vdc)

The top part is EXACTLY what I was looking for, although the bottom part could help others.

Why silve iodideAgI a compound used in photography has much higher melting point than vanillin c8h8O3 a sweet smelling compound used in flavorings?

Silver iodide (AgI) is an ionic compound with strong attractions between oppositely charged ions, resulting in a higher melting point. Vanillin (C8H8O3) is a covalent compound with weaker intermolecular forces, leading to a lower melting point. Ionic compounds typically have higher melting points compared to covalent compounds due to their stronger bonding interactions.

When photographic film is exposed to light the salt on the film breaks down what metal is formed?

The "salt" you are referring to is actually called silver-halide and are more commonly known as "silver salts". When silver-halide crystals are exposed to light, they form a compound known as "metallic silver"

Is water the only molecule that is polar?

No, water is not the only molecule that is polar. Other examples of polar molecules include ammonia (NH3), hydrogen fluoride (HF), and hydrogen chloride (HCl). These molecules have an uneven distribution of charge, causing a separation of positive and negative regions.

What animal uses a pinhole photography to see?

The nautilus is the animal that uses a pinhole-type eye structure for vision. This primitive eye design helps the nautilus sense light and detect predators in its ocean habitat.

None polar molecules?

Nonpolar molecules have a symmetrical distribution of charge, resulting in no significant difference in electronegativity between atoms. Examples of nonpolar molecules include hydrocarbons like methane (CH4), carbon dioxide (CO2), and diatomic gases like oxygen (O2) and nitrogen (N2).

When were telescopes used to see and to photograph the planets Neptune Uranus and Pluto?

Saturn was the outermost planet known until William Herschel discovered Uranus in the late 18th Century, so unless you count this as ancient, it would be inaccurate to say that the ancients could 'see' the planets beyond Saturn.

Telescopes are first definitely attested in the early 17th Century. Photography in the modern sense (using a camera to record sharp images on a light-sensitive film, as opposed to more basic forms like the pinhole camera) didn't exist until the early 19th Century.

I'm guessing that your question arises from the (quite sensible) assumption that all of the planets were named by the ancients, but this is not the case. The 'trans-Saturnian' (if you'll pardon the term) planets were named after Greek and Roman deities by later astronomers.

Interestingly, Uranus and Pluto are named after Greek gods, rather than the Roman gods that give the other planets their names. I suppose that 'Caelus' and 'Dis Pater' didn't quite have the same ring to them.

Hope this helps.

What is abstract photography?

Abstract photography are taken of very dramatic images. It relies on more sense of form, color, and flow than it does on detail. Abstract photography minimalism digital and film photography of places and things from a different perspective.

What is oblique aerial photograph?

An oblique aerial photograph is a type of photograph taken from an aircraft at an angle, rather than directly overhead. This perspective allows for more detailed views of objects and landscapes, making them useful for mapping, surveillance, and other applications.

How is water a polar molecule?

Water is a polar molecule because it has a bent shape with oxygen being more electronegative than hydrogen, creating an uneven distribution of charge. This results in a partial negative charge on the oxygen atom and partial positive charges on the hydrogen atoms, making water a polar molecule.

Water molecules are polar with the?

oxygen atom being slightly negative and the hydrogen atoms being slightly positive. This polarity allows water molecules to form hydrogen bonds with each other, giving water its unique properties such as high cohesion, adhesion, and surface tension.

What are the long term effects of placental abruption on the mother?

I have had two boys via emergency caesarian due to placental abruption. For my first child, both of us were very lucky to survive, he was in special care baby unit for three weeks and i had to have blood transfusions, my uterus did not contract properly after delivery and my blood was not clotting. I had a priest come to see me and also wanted to see my son. It was very scary and the thought of me losing my son was unbearable. I have blocked out most of that time and tend to focus on the future. I also had a second child and was high risk. I had a caesarian planned for 5th may as i was high risk but went into labour on 2nd may. In third stages of labour i suffered a placental abruption but this time round i knew what was happening and my boy was in distress. Everything came flooding back and i was hysterical as i didnt want to lose him. Luckily after emergency caesarian he was okay no stay in the special care baby unit but i was borderline for a blood transfusion and they decided against it. This resulted in me being severely anaemic and very ill for a week or so after the birth.

The long term effects are really mental rather than physical. I have since found out that i have an iron deficiency which contributed to why this happened to me. I stay focused on the future and not on the past and count my blessings that both of my boys and me survived as there are so many cases where this doesnt happen. Neither of my childbirths hold pleasant memories but the memories we have built thereafter are brilliant ones and i wouldn't wish it any other way.

What causes water to be a polar molecule?

Water is a polar molecule because of its bent shape and the unequal sharing of electrons between oxygen and hydrogen atoms. The oxygen atom attracts electrons more strongly, leading to a slightly negative charge near the oxygen and slightly positive charges near the hydrogens.

What elements are used in photography?

Elements used in photography include lighting, composition, framing, perspective, color, texture, and contrast. These elements are manipulated by the photographer to create visually appealing and interesting images.

Why are water molecules polar?

A water molecule is polar because there is an uneven distribution of electrons between the oxygen and hydrogen atoms

Answer

A water molecule is polar because there is an uneven distribution of electrons between the oxygen and hydrogen atoms. The negative pole is near the oxygen atom and the positive pole is between the hydrogen atoms.

How can you remove felt tip pen ink from the front of a photograph?

My granddaughter (age 2) drew, with a blue felt pen, all over her aunt's wedding pictures (2 of them). I tried Windex, hairspray and carpet cleaner but nothing touched it. Then I tried a non-acetone nailpolish remover. This did the trick! Worked like a charm. This took all of the ink off and didn't touch the finish (these were professional photographs). I don't know if I would attempt this on pictures straight from an ink-jet printer, though.

How is chemistry helpful in photography?

Chemistry is essential in photography for developing film and creating prints. Chemical reactions are used to expose light-sensitive materials, such as silver halide crystals in film, to create an image. Understanding the chemical principles behind these processes helps photographers control the look and quality of their photographs.

What is a lens element?

A camera lens is actually made up of many smaller lenses; from one to twelve (or more, depending on the application). A lens element is just one of the many others that is inside the camera lens. Lens Barrel: The complete camera lens that houses the many individual lens elements. It also has the mounting hardware located in the rear, which connects to the camera body.

What are some examples of polar molecules?

Water (H2O), ammonia (NH3), and hydrogen fluoride (HF) are examples of polar molecules. These molecules have an uneven distribution of electrons, resulting in a partial positive and partial negative charge on different ends of the molecule.

Why are some outlets upside down?

Are you asking about a standard USA 120 Volt domestic wall socket containing a pair of outlets, where one outlet is positioned below the other one but looks upside down? If so, here goes:

Each pair of socket outlets is made like this: a springy brass contact strip is fitted underneath the top outlet's left hole to connect it to the bottom outlet's left hole. Another springy brass contact strip is fitted underneath top outlet's right hole to connect it to the bottom outlet's right hole.

One supply wire is connected to the left-hand contact strip and the other supply wire goes to the right hand contact strip.

It doesn't actually matter which outlet hole is the hot and which is the neutral because the system allows you to put in an ungrounded plug either way round.

If there are any ground holes these are positioned above and below each pair of the contacts described above, at the mid-way point. The top outlet's 3 holes then look like one triangle and the bottom outlet's 3 holes look like another triangle that is upside down to the top one!

Another answer

The NEC does not specify what position a duplex receptacle is placed. However, some electrical plans, such as those for hospitals, may call that receptacles be placed with the ground hole facing up. This is to help prevent contact being made with the hot and neutral with something falling on a plug of a cord. The ground prong may help protect this from happening.

The other school of thought is that with the ground hole facing down on a duplex receptacle if the plug of the cord has something fall on it the last blade to disengage would be the ground pin.

Another explanation

Reason why "ground-down" is best/safer: the socket for the ground pin should be down because, if the plug starts to work its way out from weight on the cord, the first things to disconnect will be the power pins and that all-important ground pin will be the last to go, thereby providing its protection until no longer needed because the power pins have been disconnected first.

Example of amphipathic molecule?

An amphipathic molecule is a molecule that contains both polar and nonpolar regions. As the answer above said amphipathic molecules have two ends. A Hydrophilic end or a polar end, and a hydrophobic end or a non-polar end. Amphipathic molecules are extremely important in the human body. because they function as transporters of hydrophobic material in the hydrophilic environment of the body. A simple example is that lipids (fat) can not circulate the body along with blood unless it is bonded to an amphipathis molecule or else lipids will not be able to move in the vessels and will make obstructions.

Value of p3 zoom reflex bolex with case?

The only way to see the value is on Ebay. You can search previous auctions of similar cameras, or just offer it for sale, with or without a minimum. Even if you had a catalog of values, they wouldn't be current. Good luck.

What are thermal images?

Thermal images are much the same as regular images on a camera, other than the sensors used are either designed or have filters added to respond to a specific range of the light spectrum.

For instance, most of today's cameras have an infra-red filter built into them to specifically filter out the light range. However, if it's removed, it's possible to be able to take images based on the heat signature of the item being photographed. Although the sensitivity isn't the best, in most cases it'll work. ****************

Methinks the contributor doth confuse thermal with infra-red. I believe the above answer is true for digital cameras only, but such photos are not "thermal" images. Infra-red photography can also be practiced with a regular film camera, infra-red film and filters to enhance the result also. Either method requires light to be reflected from objects to the camera...a major difference.

Thermography is the rendering of images using only heat as the energy source, which is far below the capability of any light sensitive camera as far as I know. Such a camera has sensors which work whether visible light is present or not. If you can take your ordinary digital camera and render a picture outdoors at night with NO visible light whatsoever, I will eat humble pie. See this link for more on thermal imaging. http://en.wikipedia.org/wiki/Thermography

What type of zoom results in increased magnification without a change in image quality?

Optical zoom results in increased magnification without a change in image quality because it physically adjusts the lens to zoom in on an image. This is different from digital zoom which enlarges the pixels of an image resulting in reduced image quality.

What is the frequency of infrared ray?

Infrared (IR) radiation is electromagnetic radiation of a wavelength longer than that of visible light, but shorter than that of microwaves. Infrared radiation has wavelengths between about 750 nm and 1 mm. To convert wavelength to frequency, divide the speed of light by the wavelength. Speed of light is 300000000 m/s so 1mm corresponds to a frequency of 3E11 or 300GHz 750nm corresponds to a frequency of 4E14 or 400THz if I didn't drop a decimal point somewhere.
