stay away from ebay

its either the power and cable run, or that camera series is faulty. try bench testing with direct connection to a power outlet, run a tour and see what happens. Even better if you can turn it upside down to get the effect of it being installed. let us know!

get a low voltage license. write a business plan. market yourself and your company. Done. Yah i wish it was that easy. can you be a little more specific, what areas are you not confident in?

you might try a CAT5e cable with a signal booster... of course use active/passive baluns to convert to BNC. I didnt think you could actually run the far on a coax cable, hooked up to just a monitor. dont forget, when you go from the camera to the LCD, the camera is powered. when you run from a DVR to an LCD... there is no power source. let us know!

this link to the pt head is nothing like the one in the first post. clean your glasses

Although I'm sure they do exist, if you could do a write up on any IR cam that can go 600ft I would love to see it in action. pictures, reference points, etc. thanks!

there is a patent on this device! Dont go around throwing people under the bus LOL

The Real Manufacture is SAE. They are the biggest in the China. http://www.saecctv.com/en/product/ArticleShow.asp?ArticleID=157

What type of service do you perform every year?

Auto-iris allows the camera to control the lens iris to adjust for varying lighting conditions. There are often two related options as well, DC and Video - DC means the camera actually controls the iris, Video means the camera only supplies power to the lens, and a sensor in the lens controls the iris. Backlight compensation, to simplify, brightens the image so that dark objects can be seen in strong lighting conditions. This is most often used in instances where, say, the camera is facing a door where bright outside light will cause it to dim, and the lower indoor lighting means people (and particularly their faces) will simply be dark blobs. White balance allows adjustments for different "temperatures" of lighting. Incandescent light, for example, tends to have a lot more red and yellow than other lights, while fluorescent tends to be more blue/green-ish. That's why you'll often see fluorescent light over the fresh veggies in the supermarket, but incandescent over the meats. Your eyes and brain process light to compensate for such color shifts, but because camera sensors see all colors equally, they'll show those color castes, unless you adjust the "white balance" to allow for it. Slow shutter provides better low-light images by reducing the shutter speed below the normal, which allows more light to be collected by the sensor... however, that also allows motion blur to occur. Because of this, slow shutter is not normally useful for CCTV; there are instances where clear picture is more important than lack of blur, however, so this option is provided on some cameras. The Mirror option simply flips the picture left-to-right, as if you were looking in a mirror. Some cameras also allow you to rotate or flip the image vertically (top to bottom). This can allow you to compensate for a number of different installation situations. That's great, thank you. This Camera is known for Very Low Lighting conditions which is why there is a .001 LUX, BUT the reason I believe it can go so low is because of the Slow Shutter Speed. I can't see what this is useful is there is just a big blur... Why can the Sanyo See so well and this camera not? Does the Sanyo just automatically adjust to all lighting conditions? Here is the Part #VCC 4594 Also if I set the camera for night operation, will it affect day time as well? I've always wondered the difference between the "up and coming brand" and a Brand Name such as Sanyo, Pelco, etc... I'm guessing the brand name's aren't just hype...

Lately I've been reading this forum and been getting schooled, I figure I could get some true professional information. I've been trying to really learn the CCTV Market since Jan 07. It's been 3 years and I really don't know Sh*t. So if you would, please School me. I just did this job for my friends manufacturing facility. He had 10 Existing cameras already installed, so I added 54 more cameras. The camera That I put in is an Up and Coming Brand. When you take the existing Sanyo's and put them side by side with the Up and Coming Brand, there is a HUGE Difference. It's actually quite amazing. Here is what my camera is seeing: Here is what my Black Berry (No flash) Camera see's: Here is what the Sanyo Camera is seeing: With my Black Berry (no Flash) seeing this: Now the reason the Subject line reads what it does is because when I look at the sanyo camera(Below) there are no dip switches... On my up and coming camera, there are... MANY... I know what the abbreviations stand for, but what do they actually do for the camera? AI, (Auto Iris) BLC, (Back Light Compensation) ATW, (Auto Trace White) MWB, (Manual White Balance) AWB, (Auto White Balance) SL, (Slow Shutter) AES, (Auto Electronic Shutter) AGC, (Auto Gain Control) MIR, (Mirror) Y/C (Luminance (Y) & Chromincance © Obviously the up and coming brand, has a sh*t image. I'm trying learn about these settings so i can set this camera appropriately. Up and Coming Brand specs: Image Sensor 1/3" High Resolution Color Sony CCD Effective Pixels 811H x 508V Scanning System 525 Lines 2:1 interlace Resolution 540TVL (Color), 600TVL(B/W) Shutter Speed 1/2 ~ 1/120,000 S/N Ratio more than 55dB Sync. Systerm Internal Min. Illumination 0.001 Lux (Slow Shutter, 32x) Power Supply 8VDC~30VAC Power Consumption 0.8W Thanks for your help! Nick

The Nuvico EVL-800N might have given you a better recording and display resolution... The H.264 compression is suppose to be better than MPEG4.

Hey guys, I've been under the impression that an IR CUT Filter is supposed to give you the best night time picture because of the physical filter for the day/night function as opposed to a digital day/night function. what am I missing? I'm going based off of a camera I installed which offers Sony HQ1 DSP Mechanical IR Cut Filter min Lux .15 << not sure why the lux is so high. I'm getting a disgusting image at dusk and when in B/W mode its blurry. Obviously I'm changing the camera out BUT... what IR CUT Filter?? Thanks!

Actually, both are light, just different frequency ranges. We can see in the range blue to green to red, and then our ability to see light falls off just beyond the red, called infrared. Many sensors can see both the visible spectrum and infrared spectrum. Filters are typically used to create a color image. A Bayer filter is used to separate the blue, green, and red channels, and an IR filter is used to enhance the color image by removing the infrared. In the daytime, there is plenty of light, so they can afford to filter the IR. At night, sensors need all the light they can get, so they remove the IR filter and use both the visible spectrum and the IR spectrum. Best, Christopher I now understand that with an IR Cut Filter Camera that the Filter makes the camera "a COLOR camera." Without the Filter, the camera is B/W. Rory, when you say digitally enhancing the colors, are you saying there is a digital enhancer with an IR Cut Filter?

OK got it, thanks for your help I really do appreciate it!

Im not sure what your question is here, but ICR does not remove glare. When I hear you guys talk about Infrared during the day, I assume the sun. The only issue I can see with the sun might be glare or something of that sort.

Got it. Not to drag this on, but regarding Digital D/N, it's just an internal component switching modes correct?

Hey Chris, Thanks for the reply. Visible Spectrum = Light IR = Glare Glare = Bad IR Cut Filter = Stops Bad Stopping Bad = Good Picture Good Picture = Happy Thanks, Nick

OK, so the IR Cut Filter has nothing to do with B/W mode? WDR cams are used for facing doorways or windows and what not. Can you give me an instance of when this type of camera, IR Cut, should be used?

Hi, the difference with the "value Line" is the copper braid. The braid is not 95% copper but does give you 95% COPPER COVERAGE, this is the difference. We have heard people copying our cable now but being very shady about it, for instance to cut costs, the manufactures overseas will use recycled PVC which is heavier and breaks apart a lot easier under hot or cold conditions, a few years down the line service calls galore. the center conductor may be solid copper but is it the correct gauge? a lot of them try to swindle the specs. the main main main difference with solid 100% genuine solid copper cabling and 95% copper coverage "value line", "overseas manufacturing" is when both cables go from point "a" to point "b" the picture from the solid copper cable looks much better than the cheaper 95% coverage cable. EVERYONE is using the 95% copper coverage cable, you have to, in order to compete with local installers. we took a huge market away from the belden, westpenn, etc. they HAVE to put in the value line now.

how is it possible to NEVER us IR? do you mean just domes or IR in general?

Hey Guys, I was contacted by a rep from Bolide Tech. They have a H.264 Stand Alone DVR that they say is a great unit. Have you heard anything about them? I heard these units produce a blocky play back? Also, IC Realtime has an H.264, what r the differences? thanks

whats the dumbest place you've mounted a camera, or you've seen a camera mounted! of course no-one here makes any mistakes!

You Rock! Thank you very much!

Basically I need to convert Panasonic Protocol to Pelco. I can not use a coaxitron converter. any suggestions? thanks!
