For PTZ IP cameras, how about; Panasonic KX-HCM280A Toshiba IK-WB15A or IK-WB21A Axis 214

Sounds as he was just misinformed.

Conversation with a vendor about DVRs' brough up the terms D1 thru D4 or D5 (don't remember). It was stated it was a quality rating (not exact words) regarding the recorder.

Anything with a composite/S-video/RGB/component (if there are any) outs. IOWs'; NTSC/PAL.

That would depend on your defination of the term "good". That tells me your looking at top end as being good. How about good enough?

Aren't there terms defining recording for CCTV applications?

Has anyone compared a manufactures base line camera with the step up version? Example; Panasonic WV-CP252 vs the WV-CP482 Bosch LTC-0455 vs the LTC-0955

Never heard of what??

That (edited) link I posted, is that the same 'D1' as you mentioned??

How many companies (other than fortune 500) would pay $1200 to $1800 for just a single camera (w/o any accessories)??? Recomendations for something well UNDER $500?

When you refered to "D1", my understanding there are 4 or 5 "D" specs for CCTV digital recording, or am I getting thsi wrong?

The way I have extended a 'S' video cable is NOT to use a 'S' video cable. I will 'cut' a 6' S cable, separate the two inner cables, solder a RCA fitting on each cable (four in all, two for each end) and use RG-59 with the matting connector to extend the run. The pair of cables (one for 'Y' and the other for 'C') has to be the same cable (off the same spool) and the same length. As much as I liked and used the S-VHS format, JVCs' choice for the connector and what I find within that 'S' cable just plan sucks. It's usually only 26 guage which is very fragile and tough to work with since it will break very easily. Where the very small inner coxial cable meets the connector (RCA or BNC) you need to be careful of stress., I put a couple of layers of 'Scotch 33' electrical tape (the only stuff I use) and then use heat shrink tubing to seal theat end. There are break out cables available if you can find them and don't mind paying the difference. Maniaxx is right on with his description of S video. Actually Y/C is the correct term. When S-VHS came out 18 or so years ago, I ran some tests between the same feed from composiet and then the S-video. As far as bandwidth, it was only measurable on a scope with a multiburts pattern, but the dot crawl was vey noticeable on the TV. BUT, that only depended on how good or bad the comb filter was in the set. better filters reduced the difference (composite looked better) which meant there was less of a improvement over composite when the Y/C path was used. I'm sure if you compared a 3 chip CCTV cameras composite vs Y/C out (if there is a camera that has both) the difference would be greater. AFAIK, JVC shot themselves in the arm with all their talk about S-video and having a TV with that input. I feel most thought, if you didn't have that type of set, you wouldn't gain anything. Hence, why S-VHS didn't sell as it should of. It was their 'Sony' mistake of the 90's.

The biggest issue I see with most of these 'wireless' systems are omni directional antennas as in a single rod (rubber duckie if you will). Instead of all the 'RF' going in one direction (where you want it), it gets dispersed 360 degrees. This goes for the receiving antenna also. It receives from 360 degrees. Of course this doesn't apply to 'yagi' or 'dish' type antennas on the much more expensive systems.

So are we.

I started this (edit the 'dot'); cctvforum DOT com/viewtopic.php?t=8242 Just don't know how 'good' they are yet.

Is this the 'D' categories/specs you mentioned?; hdtvmagazine DOT com/forum/viewtopic.php?t=6350

Examples?

I know LCD & analog CCTV cameras don't mix well, but there are advantages to LCD monitors; 1. Much less power consumption and heat generation, 2. Small footprint, 3. Very little overscan (huge problem with CRTs', especially cheaper ones), 4. NO convergence, varing grey scale or drift issues. 5. No geometric distortion. Since they require 1 to 1 pixel mapping from a digital source (a computer with a DVI out for example) to obtain the correct image, CCTV cameras, especially the cheaper ones look terrible on them. BUT, for non critical applications, say for an aux. monitor for a area where the viewer will be close to the screen and space is a premium, a small LCD seems to be the way to go. After searching for hours, the two names that come up the most are Tote Vision and Marshall Electronics. Both are well known names in the video production/broadcast business for monitors used in EFP (electronic field production). The problem is, they are very expensive. For what a 8 or 10" monitor costs, one could buy a high end 22" computer monitor. Then I just happened to stumble across something I never thought of, LCD monitors for cars. Small 10" and under screens designed for TVs' in cars, vans etc. for DVD players. The name that kept coming up was Lilliput (edit the 'dot'); lilliputweb DOT net/product7.html Here is the site in the UK; lilliputuk DOT com/products.php?cat=4 They have models up to 10". Many are 16x9, so you have to be sure of which one to choose since those are someone useless for 4x3 CCTV use. Some are touchscreen for computer use, but also have composite video in. At 1/3 the price of Totevision it was worth a try. In the US these are sold from either e-bay or from Amazon (w/ Amazon being the better choice). The model I evaluated is the 858GL-80TV. They have a few different 8" versions with or w/o touchscreen. This one doesn't have touchscreen or a VGA input. It was $40 less than the one that did. The 10" version (w/ touchscreen) is $40 more over the 8" w/ touchscreen. The 8" has 640x480 native resolution, while the 10" has 800x600. I didn't want/need touchscreen, and with 640x480 being close to the NTSC standard with this model made the most sense. Pluses; 1. Cost (1/2 over 'professional' models) 2. 30 day return policy (Amazon) 3. Removable stand 4. Very efficent switching power supply. Almost no draw when off, 14 watts when 'on', 5 watts if input is blank, 5. Remote control. Minuses; 1. Silver case (shown to be black in listing), 2. Very flimsy stand. Easy to tip over, 3. Very narrow vertical viewing angle, 4. Antenna connected to top of case without any tuner (adds to top heavyness), 5. So-so picture quality (no other small LCD to compare it to). 6. Propritary connector for video & power inputs. Long thin, fragile cables. I have seen these smaller portable 'test' monitors sell for around the same price. With some modification the smaller versions (under 6") could/would be a possible subsistute. If anyone else has found some other solutions, please post your finds here.

I never really got into lens specs regarding resolution. I do vagely remember that tidbit, but completely forgot about it. I guess Tamron 'assumed' one would know this. Out of all the lens with specs listed (major manufactures), until this one, that would be a bad assumption on their part as no spec included this I have seen. Anyone know of any lens spec that lists resolution?

I remember reading that. It sounded kinda odd to me. I'll give you that one. As far as coming up with a solution, at least he brings to the table the problems many are unaware of. Maybe you could bring to the table some solutions (other that IP cameras).

It surely doesn't say that! I just finished reading this test chart setup document (edit the 'dot') and discovered the same thing which I didn't know; cctvlabs DOT com/TestChart/cctv_test_chart_instructions_latest.pdf and on page 14 I see this; Comming from a television background resolution is always the whole screen, not per mm.

I understand he has something to sell (hence the warning in the 1st post), but being familar with 'sales' hype in both the consumer and 'professional' world, you have to admit what he says about the quality of CCTV images is dead on. The best CCTV image I have ever seen looks like crap compared to the worst local originating cable TV broadcast (public access) which are usually pretty bad to begin with. His "techno-babble" has far more truth then anything else I have read regarding CCTV equipment. There are too many 'sell and run' artists who will con the customer into almost anything no matter how poor the image is as long as the $$ is there. Tell us, what are the other areas where you think he is in error?

Exactly, what is/are the model number(s) of this/these cameras??

Here is the link for the pdf (edit the 'dot'); tamron DOT com/cctv/prod/assets/pdfs/HiResCat.zip Is this the 1939 World Fair??

Yea, forgot about the composite out. Well, it's still better (at least on paper) than most others except 3 chip designs. Hitachi has one around $2300 and Sonys' version is around $2500 Ok, how about this (edit the "dot"); avsupply DOT com/details/ik-tf2.shtml
