If you have 2 DVD recorders can you hook both of them up to the same TV and play a DVD on the DVD player while you record what you are playing on the other DVD recorder?

Yes, although you may need to get a switch to select which recorder you want to watch.

The easiest solution is if your DVRs both have HDMI outputs, and the TV has 2 or more HDMI inputs. You simply select the DVR you want to watch by choosing the appropriate HDMI input. Similarly, if one DVR has an HDMI output and the other has component or composite outputs, you can also switch units by choosing the appropriate input on your TV.

If your TV does not have enough HDMI inputs (or none) then you may need to get a switching box that will allow you to connect two devices with composite or component outputs to a TV with only one set of inputs.

Can you playback video from an analog camcorder through a digital tv?

Yes, most analogue camera's have an AV output. It may have a special small plug and an adapter ending in 3 phono plugs. Red=Right audio, White=Left audio, and Yellow= composite video.

Most Digital TV's have AV inputs, which you can select from the menu.

Connect the cable to the TV, select the correct AV in, play the camera. It should now show on the screen.

Can a dual tuner dvr record 2 shows while watching a live program?

For every program being received, a tuner is required. A dual tuner allows one channel to be viewed and one other to be recorded. It is normally possible to record the channel that is being viewed, so strictly, yes, it is possible to record two shows while watching one of them. Watching a third channel is not possible.

What is the difference between 5 optical zoom and 8 optical zoom in a camera?

If you're talking about optical zoom there is no difference other than you will be closer to the viewed object.
If you are talking about digital zoom, the size of the pixels will increase and blur.
Hope that helps!

How can you convert Hi 8 digital tapes to DVDs?

Send your tapes to a video transfer service. They will have a Hi8 player and be able to convert your tapes to DVD. Some, even have the option for you to edit online or get digital files back on a portable hard drive. StashSpace.Com can do this for $7 a tape. http://www.stashspace.com/video-transfer/hi8-dvd-transfer.stm

Another option is to borrow or purchase a Hi8 player from a friend. However, in this case you still need a video capture device to convert the analog signal to digital.

If you want to convert a Hi8 or standard 8 tape to DVD, you MUST have a player.

* If you only have one or two tapes, then try to borrow a friends, or purchase a Hi8 camera. * There are plenty of folk willing to do the conversion for you ... for a price. Anywhere from $5 to $10 per tape. * If you have lots and lots of tape, consider purchasing a tape player, not a camera.

I have a lot of Hi8 tape I need to covert, so I'm looking at purchasing a player.

While you're at it, you might want the files converted to MPEG4 or DIVX, as this allows for high quality at a small file size. I plan to convert all files to both MPEG4 (for future editing) and MPEG2 (which is used to create standard DVDs).

Can a analog video cassette recorder record from a digital television?

VCRs do NOT process digital signals, analgue is the only language they understand. Therefore, you need to place before the VCR a device that has a digital tuner plus the ability to convert digital signal to analogue.

Examples of such devices are a cable / satellite set-top box, a digital to analog converter box (the converter box ONLY works IF your digital TV feed is coming from an over-the-air TV antenna, not through underground cable), and a stand-alone DVD disk recorder "with a built-in digital tuner".

Whichever tuner plus converter device you have, connect either S-Video or Composite Video AND RCA (red and white) audio output of the device to the input sockets of your VCR. Make sure that whatever "types" of video and audio connections you make are available on both ends, as output on your tuner/converter device and input on your VCR.

What are the features of a dvr recorder?

It depends on the type. The most basic DVR recorders allow a user to record a program from TV onto a disc to be viewed later. Some DVRs offer other features including the ability to skip over commercials.

How long do stores keep surveliance videos?

After extensive research on this, I'd have to say at least 30-60 days, but especially with the latest DVR systems, some companies may keep up to 2 years of footage easily.

Does DVR need to be turned on to record scheduled program?

No it does not. Technically, it never is 'off'. The two lines that come into the back of the DVR are both solid constant feeds coming in, and the DVR is constantly monitoring start times that are your scheduler.

** Additionally, it is BEST to 'shut off' the DVR when you want to record 2 simultaneous programs on different channels, so that it is not using one of the feeds to display the channel it is tuned to (even tho your tv is shut off) while the other feed is used for recording.

When the receiver is 'shut off' it will use both feeds to ensure successful recording of both programs.

Can you record from pvr to DVD?

Most DVRs have their own tuner(s) built in. So it is not a matter of recording from a TV.

A DVR can record alone without a TV being attached. The problem arises when you want to program it. You need the TV to act like a monitor and see what you are doing.

Where can one purchase a micro camcorder?

There are many places one might go to purchase a flash memory camcorder. In addition to a store like Best Buy, one might also consider purchasing from Amazon.

Can you record the video part of omegle?

Omegle should ask you if you want to download a file with the chat text in it after the chat with the other user ends, it should be a .html, .htm, .xhtml, or a .txt file. Or you could just use Windows Screen Capture by pressing PrtSc, then going into MS-Paint, then pasting, then you can save it as a JPEG Image.

What is the best digital camcorder for under 200 dollars?

The JVC Everio GZ-MG37 Hard Drive Camcorder is one of the best camcorders for under $600.

Who invented the video recorder?

"Friedrich Matthias of IG Farben/BASF developed the recording tape, including the oxide, the binder, and the backing material. Development of magnetic tape recorders in the late 1940s and early 1950s is associated with the Brush Development Company and its licensee, Ampex; the equally important development of magnetic tape media itself was led by Minnesota Mining and Manufacturing Company (now known as 3M)." huma nan

How does a night vision camcorder work?

A beam of infrared light is sent out which is invisible to the human eye. However just like a digital camera the goggles can pick up the infrared light and convert it into the visible spectrum and display it on an small lcd screen inside the goggles. Wearing these on guard duty a couple years ago I found them very strange. First all you have no depth perception and if you look at anything too bright you're gonna get blinded (temporary). Sorry I don't know the technicalities but I would find out by looking for a book at your local library consortium under "how things work". Night Vision Goggles, (NVG), work by amplifying light � moonlight, starlight - in the Near Infra Red, (NIR), region of the spectrum � approx� 600nm to 930nm, (Gen III). NVGs incorporate Automatic Gain Control, (AGC), this controls the amplification, (gain), of the NVG which helps maintains an acceptable level of contrast of the image presented to the viewer. E.g. a scene viewed under illumination from the full moon will cause the NVG amplification / gain to reduce. The same scene viewed with little NIR illumination will cause the NVG amplification / gain to increase and results in a reduction in the quality of the image being viewed due to �spangles�, (flashing pin points of light on the image), which is �noise� from the amplification / gain process. Incandescent bulbs in addition to visible light, release most of the energy produced in the NIR and IR spectrum, (heat). NVGs used by a sentry to view an approaching vehicle which has illuminated headlights, will find the NVG �blinded� by the amount of NIR being produced by the headlights, similarly NVG used by a pilot can be �blinded� by cockpit illumination � the AGC can only cope with a limited range of NIR illumination before the goggle is saturated � �blinded�. The image presented to the viewer using NVG is monochromatic � green. The image is 2 dimensional � no perception of depth. This makes operating a vehicle or aircraft using NVGs very difficult, since distance and closing speeds are very difficult to assess. Most of the NVG sold commercially are � at best - Gen II, which is very poor in comparison to the GEN III - restricted technology � currently used by the military. Passive NVG's work like this: light photons will come it (any tiny bit of light, moonlight, starlight), and come into the goggle, and it turned into electrons. then, it hits a very thin charged disc, with millions of channels in it. the electrons hit this, and going through the channels it will release millions more electrons. then, these electrons hit a phosphor screen and they basically spread the very little bit of light all over the phosphor screen so you can see. it is actually manifactured so it turns out green, because the human eye can decipher many different shades of green than any other color.

How are magnets used in tape recorders?

A cassette tape is based totally off of a magnetic system. The magnet is what reads and writes the information to the tape.

What is the cheapest DVD recorder?

It depends on the software and hard disk. Well there are plenty of cheap video recorders, to choose from to find the cheapest it would be a case of shopping around and looking for the best prices.

How do you charge a Vivitar DVR 947HD camcorder?

You don't. This DVR uses 4-AA batteries. To replace the battries look under the hand-strap for a removable door that slides open towards the bottom of the camera.

What can one do with a DVR system?

Here are a few things you can do with most DVRs: * Record movies and television shows from your cable service. * Pause or fast-forward live TV. * Use the Internet to schedule your DVR to record your favorite television show. This may require the download of additional software onto your PC and/or require you to add your DVR to your home network. * Search your cable listings by actor, time or even director. * Download and share digital photos and music from your computer and DVR. This may require the download of additional software onto your PC and/or require you to add your DVR to your home network.

Can you record a VHS-c tape in a VHS adapter in a VHS camcorder?

Yes, using a VHS-C adapter will allow you to record and play VHS-C tapes in a VHS machine. The adapter simply changes the casing format. The actual tape is the same. I'm not sure why you would want to, though. VHS tapes are cheaper and the tapes are longer.

How to record movies from a laptop to a VCR?

This is going to be tricky. First you need to have a VHS player connected to a TV to be able to record. Next, you will need a graphics card with a video out, or you'll need to buy a PC to TV scan converter. With either one of these, you'll be able to play the movie on your TV while you are recording the VCR. Please note, that playing PC files on your TV will not have the same quality as your monitor, so there will be noticable quality degradation.

How could a TV turn itself on when no one is home or in the middle of the night?

This may sound simple, but does it have a timer/alarm feature on it? I had the same problem and it was the timer. It had been accidently set by the kids pushing buttoms. Once we went into the menu and disabled the on/off timer, the problem was solved.

If your TV has a remote control, try replacing the batteries.

When my batteries start to die, the remote sometimes does things on its own (change channels, adjust volume, or turn off).

Being a Electronic Technician, I have seen Sets that have a 1ohm resistor in the circuit that has changed value, and will contribute to this problem..Just one of those things to look for..And probably the most common,if not a remote malfunction. keep remote in another room when going to bed, and make sure the timer isn't set on your tv...if it again turns on by itself, suspect a resistor problem.
