If it's a "book" you want, this is the best... PhoenixCCTV : author Title: CCTVStuff Everyone in our industry should read this: Vlado Damjanovski CCTV /// look it up.

dude... what is a "8800 DVR" ??? Please be more specific to brand and provide details for reference. Maybe Kodicom DVR cards???

good job Jasmine... Looks to me like Dudu man is ready to buy from you. He did not read between the lines to notice that your DVR is limited. You have your USA distributor ready to purchase. Your customer service is 100 percent! How about your products?

Wow... have not been here for a few weeks. You boys are way of the subject! I really do appreciate all of the comments on resolution and why it is all whacked out. thank you Amir for your in depth explanation of TV lines and pixel ratings... but... at the end of the day, none of this means "sh$t" if you do not make it simple. To simplify, 1. Specs on cameras and DVR are all wrong.(no matter the manufacturer) 2. For TVs, the highest resolution is 350 lines. 3. For CCTV systems, the highest resolution is 525 lines. 4. You need megapixel cameras to get really high resolution video (see below for disclaimer) 5. most important : make things easy to understand for everybody with no lies. Now, back to megapixel: high cost, need special housings that can be used with mega-pixel cameras, network problems, internet problems, and lens problems... you dig??

Its been a while since I tested your technology... so yes, maybe you have some new specs.. tell me.. Can you playback more than one channel on the local machine? Does the unit have a network speed throttle? Or network speed display? Are you using H264 "on chip" technology or software based compression? What CPU does the unit use? what speed? Can the unit recycle video without creating a slower working environment?

Correction: Sony, who makes the CCDs and DSPs, rates all 512x492 cameras at 330TVL. Over the years, our industry has increased the TVL resolution to 380~420 for this CCD. TVL ratings are good if you have charts and can test the products. My point is this: If you want 470~480TVL, you need 768x494 EP. If you want 520~540 TVL you need 768x494 with the HQ1 DSP. All you have to do is look for manufacturers who actually write "HQ1" on the camera specs. This is easy to verify since Sony only makes one model of HQ1 DSP. Take a look at the DSP on the back of the camera board.. it should say "CXD3172AR". If doesn't, you just got swindled! I know a few manufacturers that are not on the high end of the spectrum who take pride in correct specs for high resolution cameras. Yes, they cater to discerning customers that want to buy real technology versus exaggerated paper specs. Shany, Everfocus and Eclipse to name a few that have specs within range of reality. My gripe is with companies like IC realtime, Cop, and Ateck who sell 512x492 (330~420TVL) cameras as High res 480TVL or higher. Sure, maybe they don’t know the difference, but I bet they do and just don’t care to lie. If you want proof, just visit their websites and check the specs.

Does anybody have anything good/bad to say about the ASIS show this year?

Have any of you actually used Auto-tracking in the real world? Sounds great in writing and works great in a controlled room environment, but once you apply to the real world, it usually becomes a real nuisance and fails to perform its tasks correctly. Notice the carefully phrased description: occasional presence of people or vehicles If you have a situation with little to no motion and a controlled path with no obstructions (trees, building, etc) then motion tracking is awesome. Otherwise, firmware based motion tracking for PTZs is limited in logic. I have used some extremely advance and expensive software based motion tracking that anticipates motion and can track multiple objects crossing each other, and sadly it still fails.

Hi Jasmine, Nice to hear from you! Glad to see that you have a bit of "spicy" in your blood. Funny, you never talked this way when we met at your factory. I have tested all of the chinese h264 DVRs platforms, including yours. To be fare, your DVR is actually pretty good and the most complete from the selection, but still limited for my taste. My favorite is Hangbang but they also have a big problem with network choking. So, at the end, no real winners. oh and by the way.. I can clap with one hand!

Oh.. and by the way… my original “fitâ€

Hi boys!! Sorry for the interlude.. had to take a break to visit ASIS in Atlanta or IP camera central as I call it. Now where were we? Good point survtech.. and I would add that even if the difference is minimal, I do not want to pay HQ1 (520~540TVL) prices and get SS-11X (470~480TVL) quality..also, there is a big difference in price for the components on the manufacturing side. I hope you see my point. Now Chromatic... Way to go off subject dude! It's not the fact that you did as much as how you did it. PC based DVR?? really? Everyone makes these toys man... does that make everyone a manufacturer?? You take a "back seat" attitude to these unethical practices.. I can give you a history of camera specifications and why companies like Arm are so infuriating to me. unfortunately, you have already proven that you are a waste of time for me with your post. Maybe you should throw a little fit yourself every once in while.. you know, prove that you are alive and actually care. It's called passion. If anyone need to get out of this industry, its people that see these problems and say nothing/do nothing. Gday!

Very good!! Finally.. a few guys that get it... its all about the pixels baby! Just one example: (best way to spot a fake) Sony 1/3 CCD Color Camera 520 TVL • 1/3" SONY CCD High Resolution • Super High Resolution 520TVL 0.001 Picture Elements: NTSC: 512(H) x 492(V) Anyone see anything wrong with these specs?? This camera is 420TVL at best. I can show you a bunch more, but why bother.. most good techs and distributors know that these things are out there and avoid them. Now, who wants my "black list" of companies doing this?? The admin on this forum should do the same... create a black list!

very good questions but we are discussing TV lines... not effective pixels.

Ahh.. finally a worthy adversary (in northern). You are correct regarding Samsung and Panasonic. I was hoping someone had enough experience to bring this up. Unfortunately, most of the cameras sold today (including all of the ones we are discussing) are Sony or Sharp. The Arm 600 is a Sony HQ1 rated at a max of 520~540TVL by every reputable manufacturer in the industry today. The explanation that Rory gave earlier on this thread was right on the money. Except for the that statement about not seeing a difference between 480TVL and 520TVL (HQ1), everything else is 100% correct. Your Arm 600 is a good camera, but it's not 600TVL.. it's 540TVL max.. still a lie... gotta call a duck a duck! Thank you telespy for knowing the difference. These guys like going through life with blinders on... too sad.

Another dude that believes everything he sees on a website or catalog. Arm does not make anything.. they buy it in for the lowest possible price in China. Same stuff you buy all over the web for alot less. What type/brand of CCD/DSP on this 620TVL camera?? What about effective pixel rating?? Don't know... thats because companies like ARM don't give this info. This should be enough to never buy from them.. but instead, you boys run to them and pay extra for a 480TVL cam.. Like I said before, I've got an 800TVL camera too... do you believe me? better yet, I've got some cheap beach front property in Vegas for both of you...
