okay Spytown, what we need now is an image comparison between the 3 of them in the same location, day, night, and pitch dark Good looking out by the way but why you gots my right mouse button disabled

It is a Halogen Lamp, so it will use halogen Bulbs, if you can find them in the local Home Depot? Do a search on google though there are tons of sites that sell them. Here is one source, check the bulb inside the Illuminator and match it up under the Halogen section if possible. http://www.bulbs.com/default.asp?page=products The lens is the width of beam, the lens will have the filter as you said, to filter the IR that is produced, such as 730nm, 830nm, 950nm. The greater the filter is, the IR amount is decreased, and the IR gets less visible. So a 730nm filter will produce the most available IR for a specific Illuminator. Retail the UF500 bulb is $164. Here are the General Specs on the UF500: Extreme Infra-Red flood lamps are optically precise units incorporating high quality precision filters, gold-coated or aluminium reflectors and optimised lenses. Other than the bulb replacement there are no user repairable components within the unit and it is, therefore, sealed for life. Do not, therefore, attempt to dismantle or gain access to the unit other than for bulb replacement.

Im using the Extreme CCTV Uf500 IR Illuminater, the bulb lasts approx 2 years, and then requires replacement. It is NOT a regular bulb that you can buy anywhere, though it looks similar. We buy a couple to have on hand all the time. That unit you posted is a generic unit, OEM, we used them in the beginning and chucked them after a couple months as they just didnt do the job. I cant say what bulb that uses though. Are you saying you buy a whole new unit after a year? The Extreme Replacement Bulbs are around that price Retail, but the IR is extremely better, 490' with a Spot Beam. Even the UF100 will beat that, and is the same idea, replacement bulbs. UF500 - approx distances

It is cheap Now, what they do with that compression is a whole different thing .. mind you even the cheapest DVR on the market with MPEG2 is very high quality, just lacks a ton of features and other things. That network software it uses is one of the worst Ive ever used by the way, but hey, its cheap

I got a reply from GE US, im waiting for the serial number as they as ked for t that for some reason,now this is the DSR-2000 though so may be a little different, the board is different I think, but maybe just as it misses the Mux part. Anyway, worse case I can get 2x160GB 5400rpm Recerts from Tiger in Miami for $75 each for now, then I can play with the old one some more. .. High crime night club so needs to be recording 24/7.

Its the seller that sells them crap and they dont know any different ... i say if they have the funds, sell them something good, show them the 2 side by side and let them decide. Yeah and that 0.0003 lux is actually going to be almost 0.03 Lux in reality, if that.

I wouldnt buy it You're better off with the Ganz D6000 color dome camera if you just want an indoor color dome, as the Ganz is 1/3" while that one is just 1/4". I wouldnt trust neither of them for low lighting though, neither have the CCD Chip for low decent lighting. Both use the same Chip.

ive used a 64MB onboard video before .. no issues ..

or you can use this one bahamassecurity.com/ip

I hear yah about the PCB but do you think this would work regardless, i havent got any response from GE yet, so I need to try something .. but i cant order this without being sure as it costs $600 time as it lands down here .. If i had time and client could spare time without it for a couple days, id do what you said with a PC power supply, if thats the only reason for the 5400rpm drives, though I though there was other reason?

Thanks, thats the info I needed Ill check it out some more this week. Rory

Wavelet is also a very high quality compression, but I think it takes up even more space than MPEG2 or MJPEG. Search is your friend http://www.cctvforum.com/viewtopic.php?t=1975 http://www.cctvforum.com/viewtopic.php?p=16383 http://www.cctvforum.com/viewtopic.php?p=21903&highlight=jpeg2000#21903 So to answer your question, JPEG2000.

they dont need to be formatted, as its RTOS Nucleus. They use master and slave settings as with IDE drives in PCs. Im working on the DSR2000 right now and upgrading the drives, will let you know, basically it has 2 ports, which can hold 4 drives using 2 cables. If you only bought it with 2 drives it would only have 1 cable for example. Also depends on which DVMRe you have, and how old it is. Its supposed to be 5400rpm or used to, im waiting on reply from GE on that as they are very difficult to find now.

I have Extreme CCTV cams at Luxury Homes, and even more recently, just a nornal home The GE DN cam is good.

Yep, it is over $300. KTC-2000DN Nah, the XP1 was a waste of dollars. Decent camera but I dont really sell the GE Box cams anymore, switched to Extreme. See the CCTV Catalogue on the home page. Just been busy with software, havent had a chance to update the online catalogue, no Bahamians look at it so wasnt a priority lately

Relying on DVR motion detection though .. Take a look at the Optex products, they have wired and also wireless. Basically anything you can think of, can be done without a problem, with Geo or Without it.. Ive not used Geo's full capabilities either, maybe scott J can shed some light on it, or someone else. I think we are in the wrong thread though

its just turning daylight now what do you want Geo to do for yah? They have data in and outs for that. I personally use Optex for outdoor beams, etc, you could tie them into the DVR easily. Or just use Motion Sensor Lights, they are the cheapest solution, like $30. I have a couple clients that use it even in their retal store. Rory

no IR really works on Bullet cameras, except in small spaces like rooms, etc. Even the provideo I listed wont do anything short of the following, For any IR to work, it needs to reflect off something, Unless you use an IR that Floods the area (UF500). Bullets can be annoying as people can move them. Ill check out the Sanyo Day Night dome and give some feedback on it. Otherwise the WZ30B5 high res BW Vandal Dome will work. But if you need a wall mount, then the WZ46 is designed for that. They can always add IR if needed. I would suggest motion lighting anyway for security, as well as a decent alarm system, maybe some yard beams.

Also. quality will depend on your DVR and Monitor used. And an LCD will not provide as clear video as a CRT. Also if you use the Geo DSP output it will be much better quality as it is basically analogue video, but you will need a TV or CCTV Monitor. Rory

the provideo one is 420TVL, this is it here, same exact model I use: http://www.ezalarms.com/ezStore123/DTProductZoom.asp?productID=26802 Course then I could also point you to the WizKid BW High Res Bullet Camera, not much different in price but higher res and longer warranty

Thanks man Okay, Quality between a 480 and 420 will depend on the brand name and products you are looking at. 420TVL BW can look alot crisper sometimes than 480 TVL Color as it is in monochrome only and does not need to produce color, basically. Some will argue that all cameras are Color from the start, and then a BW camera basically cuts out the chromo which then produces a monochrome image. Also, not all 420TVL BW cameras will give the same quality image, for example Provideo has a cheaper BW 420TVL Bullet, but ive used it and it sucks compared to the CVC-325 BW Bullet camera's quality. BW cameras go as high as 600TVL. No thats not overkill, heck Im viewing and recording 480TVL cameras in 720x480 mode and it makes a huge difference from even 640x480 mode. If you want color 480 is the highest you need for DVRs right now, though there are some such as Sanyo and Bosch that claim 520 and 540TVL with their cameras, basically it is digitized is all. Only High res Day Night Bullet with an Auto IR Cut Filter that I could recommend is one posted by Spytown previously, the Provideo CVC-7706DNV. Ive never actually used it personally but seen it in action, and others on this forum have used it, Specs are impressive for a Bullet camera. Ofcourse dont expect it to match up with an Extreme CCTV camera, but at what it cost it comes pretty close. Price wise it may be out of your budget, it is EXpensive ... i like to use BW in low light, and color where there is light, myself, as I know I cant afford that camera

See if you can read anything out of this article http://www.dpreview.com/learn/?/Glossary/Camera_System/Effective_Pixels_01.htm I know though alot of Bullet cameras claim 480TVL, the active pixels are less than that found in a Box camera with 480TVL from a brand such as GE. You can notice it when you put them side by side, it makes a huge difference. If you want to see them let me know, Ill post them here, same store, 2 different cameras claiming 480TVL. Ill have to wait until daylight now though. Once again, you get what you pay for Effective Pixels By Vincent Bockaert Effective Number of Pixels A distinction should be made between the number of pixels in a digital image and the number of sensor pixel measurements that were used to produce that image. In conventional sensors, each pixel has one photodiode which corresponds with one pixel in the image. A conventional sensor in for instance a 5 megapixel camera which outputs 2,560 x 1,920 images has an equal number of "effective" pixels, 4.9 million to be precise. Additional pixels surrounding the effective area are used for demosaicing the edge pixels, to determine "what black is", etc. Sometimes not even all sensor pixels are used. A classical example was Sony's DSC-F505V which effectively used only 2.6 megapixel (1,856 x 1,392) out of the 3.34 megapixel available on the sensor. This was because Sony fitted the then new 3.34 sensor into the body of the previous model. As the sensor was slightly larger, the lens was not able to cover the whole sensor. So the total number of pixels on the sensor is larger than the effective number of pixels used to create the output image. Often this higher number is preferred to specify the resolution of the camera for marketing purposes. Interpolated Number of Sensor Pixels Normally, each pixel in the image is based on the measurement in one pixel location. For instance, a 5 megapixel image is based on 5 million pixel measurements, give and take the use of some pixels surrounding the effective area. Sometimes a camera with, for instance, a 3 megapixel sensor, is able to create 6 megapixel images. Here, the camera calculates, or interpolates, 6 million pixels of information based on the measurement of 3 million effective pixels on sensor. When shooting in JPEG mode, this in-camera enlargement is of better quality than those performed on your computer because it is done before JPEG compression is applied. Enlarging JPEG images on your computer also makes the undesirable JPEG compression artifacts more visible. However, the quality difference is marginal and you are basically dealing with a slower 3 megapixel camera which fills up your memory cards twice as fast—not a good trade-off. It is similar to what happens when you use a digital zoom. Interpolation cannot create detail you did not capture. Fujifilm's Super CCD Sensors Normally sensor pixels are square. Fujifilm's Super CCD sensors have octagonal pixels, as shown in this diagram. Therefore, the distance "d2" between the centers of two octagonal pixels is smaller than the distance "d1" between two conventional square pixels, resulting in larger (better) pixels. However, the information has to be converted to a digital image with square pixels. From the diagram you can see that, for a 4 x 4 area of 16 square pixels, only 8 octagonal pixel measurements were used: 2 red pixels, 2 blue pixels, and 4 green pixels (1 full, 4 half, and 4 quarter green pixels). In other words, 6 megapixel Super CCD images are based on the measurement by only 3 million effective pixels, similar to the above interpolated example, but with the advantage of larger pixels. In practice the resulting image quality is equivalent to about 4 megapixel. The drawback is that you have to deal with double the file size (leading to more storage and slower processing), while enjoying a quality improvement equivalent to only 33% more pixels.

Also remember thermal image is the same in the day as it is at night ... so its not like Infrared Day Night Apps .. just incase FYI

id like to see that Yeah I saw Flir featured on a Helicopter progam one day (one of those COP chase programs), saw the name on the video and searched for it, they definately have Thermal down packed.

I forgot to mention, the WizKid and Extreme's are better for wall mount apps. So is the Hunt so Im told. I am in the next room didnt you know
