Wonwoo is famous of the manufacturer for housing in Korea. a lot of Korean manufacturers like to use its housing. they do not have own Dsp but they have shown good cameras.

D-WDR - digital WDR. the DSP will be Hawk from Nextchip.

We will test it soon and post it here. Monalisa(600TVL) Vs W5(or A1) (600TVL) Blue-i(580TVL WDR) Vs A1 WDR version (600TVL WDR) Blue-i is building up quite good reputation now.

Sony effio is great DSP. over 650Color TVL plus WDR and it will use different CCD(ICX662XKA, ICX663XKA) of course, some effio modules will have different CCD. effio is one of the most waited products in 2010. i heard from our R&D it has 3 versions and 3rd version will be the best. we are waiting for it with others. even though it is great, must compare each module with effio. I Just heard Samsung will show SV-5 - 650Color TVL plus WDR. they will show it at IFSEC show. it is time for us to be busy.... which one will be a winner in a market Effio or SV-5?

Hi Larry, Can you put me in the Manufacturer group? i am very excited to become a member of it now. Is it possible to be a member of different group at the same time?

we were in SecuTech Show 2010. There was no guests !!! from North and East Europe and US because the volcano eruption in Iceland. it becomes Asian show this time. anolog - new product 650 resolution by Effio, our 620 Color TVL product, other 600TVL(chipset by Samsung Techwin, CNB, LG, and etc) NVR - seems same as Japan show 2010 it seems the stand of IFSEC is not filled now cause we have been requested to book a stand till now.

YES. No Doubt. if there is one more like here, let me know.

Hi, i also recommend CNB products. the two products you are thinking to choose may be good even made in China but when i see the selling price you wrote, they can be poor quality ones. you should look for high spec like Sony 1/3" Super HAD CCD 540 Color TVL ICR IR LED over 25pcs (enough for 20m view at night) IP66~67 or Brand products such as CNB, KT&C and Taiwanese ones.

Hi, I know the dsp name of "Hawk" is from Korean manufacturer(NEXTChip). but i have not heard of Hawk-IV. you can PM me for further information.

620 Color TV line camera is out. it is developed with 12 bit A/D technology. 10 bit A/D technology in current ones. will it be top of camera in terms of resolution?

Since late of 2009, Major Chip makers are producing DSP for 1. 600TVL(Color)~640TVL 2. 700TVL(B/W)~750/800TVL Good looking All-in-one concept for outdoor use Others would be same

Sony says 520TVL in tech spec for HQ1, manufacturers say 540,550TVL. it is possbile because this is analogue. Sony products also say 540,550TVL.

I vote one for you. most spec say 0 Lux for cameras with IR LED. by the way, which camera(NO infrared) has the lowest illumination? Why dose not camera spec tell us about which IRE when telling min. Ill?

Hi everyone, i am studying about DSP(or ISP or SoC) for our new products lineup. 1.samsung Techwin W3 W4 SV4 W5 2.Samsung electronics A1 3.Next Hark series 4.Sony SS-1M HQ Effio 5.CNB Monalisa 6.LG XDL? 7.Honeywell except the above, if you know anything good PM me or Please write down here the name of DSP and manufacturers. one favor which do you like most among them? Thank you for your help

Hi i have heard that the warrantee of Sony CCD is 2 years. What about Sharp and Samsung CCD? Which manufacturers do provide the longest? Which camera maker do provide the longest warrantee?

This place is very good to share informaiton and to learn something i do not know. WELCOME.

If a CCTV camera hires Sony CCD or some major component with 2 yr warrantee and if the CCTV Camera provides 3yr or more yr warrantee. How should end consumers understand it?

I have to strongly disagree. While chipset will have an effect on the potential quality of a given camera design, there are far more factors that can adversely affect the end product: power supply design, ancillary circuit design, parts selection, production methods, quality control and a whole slew of other factors come into play. You could have two cameras that employ exactly the same chipset and one could be far superior to the other due to the other's cheap circuitry, shoddy production line and/or poor QC. That is often the primary difference between high-quality goods and cheapo stuff! I am with you 100%. forgot to say that.

Thank you very much however well, i am a manufacturer but maybe i can look for a chance for our next NVR products supporting 64 CH full HD.

Dear all, I am very glad to know this place. As i am the person in security business field, I would like to share my knowledge as far as i know. especially the latest analog CCTV. You can ask especially Korean DSP(Digital Signal Processor) now Korea releases the latest DSP most.

first of all, IR Dome design is very important. expensive one is better. I think there would be lights where the camera is istalled. If the white ring is happened by IR, the white ring would be looked like the ring with a lot of small rounds.

Hi, as a manufacturer would like to say it depends on chip(DSP) maker. for instance the DSPs (W3~W5) from Samsung Techwin are same for Samsung Techwin use and local use. It seems Sony dose same thing. When manufacturers say it has 'A' brand DSP, it needs a doublecheck carefully with 'A' brand DSP brochure which can get on website.

It seems Trustpass becomes the major income for alibaba.com. They called me very often to have trustpass. of course, as a private company, it is free to have any kind of activity for income. BUT how the private website gaurantee trustable companies. When something bad happens and they can pay for it, they can get paid for trustpass service.
