I tried using heatsinks in the 3518e chip.. but it doesn't work.. this is because heatsinks only work if there is cooler ambient temperature.. but the inside of the top201 is like inferno.. next i'll try to connect pure aluminum directly from 3518e chip to metal case and see the rate of heat...

Picture attached is a Flir thermal camera picture of the top201 that maps its processor temperature.. it shows about 67 degree Celsius.. maximum operating limit is 70 degree Celsius.. but the camera is put in open air with good ventilation.. but when you hide it on top of ceiling of inside small...

It can focus but only half *single* thread left so if you touch the lens.. it can fall down inside.. so it either must be glued or the posts cut shorter. But then using the pinhole lens. the field of view is quite small. Now I understood why the stock lens is bigger.. because it's no longer...

I tried replacing it with a pinhole lens (see attached).. it can barely fit because there is no screw left and the posts that hold the pcb is quite long. Does anyone have any idea how I can cut the 4 pcb support to make it shorter so the pinhole lens can be adjusted more front to have enough...

I did that and everything for 5 hours.. I removed the enclosure, exchanged it with each other.. removed the wiring.. and exchanged it too, etc.... and the same color banding appears in one.. the other seems to have banding too.. but not colored... accrording to the following...

if settings of the two similar models are exactly the same and it is the sensors that is the culprit.. what cause different noise patterns in the identically(manufactured) sensors of the *same* model.. is it electron doping or more of the circuitry quality? is it like in the semiconductor where...

But I have 2 pcs of exactly the same model.. both same low light target side by side.. the other doesn't have the moving color bands.. is it possible sensors of similar models can vary in the noise patterns?

I have this 1080p pinhole camera with ultra low lux sensor.. when lights are very low.. I'm getting moving color banding artifacts (like in this attached picture where you can see horizontal color line banding.. it's very dark area really). What is the exact terms for it.. is it normal?

Here's how the 720p compare to the Hi3516 1080p... Its like the image is taken from the 720p part of the 1080p.. in other words, the 720p image has narrower field of view top and down compared to the 1080p.. and they seem to resolve similar details.. The top201 is confirmed to work with NVR...

I just got my top201 and opened the case and remove the p2p sticker and take picture of the pcb (see attached image).. I can't see the "e" in 3518e.. how do you *physically* distinguish between a 3518c or 3518e (only 3518 is written). Also note the pcb is different from the genuine 3518e that...

in other words, you can hack and watch the feed of any top201 by simply plugging a dahua NVR into any lan port of the building, office or home and the bugs in the onvif implementation removes the need for any password in the NVR. Try it.

Has anyone noticed that when you use an NVR with the top201 (and it's like), you can view the feed even if the password is different? With the CMS software, you can't view it if you don't use the correct password.. but using the dahua NVR.. it can be viewed irregardless of password. What part of...

I tried using a 720nm IR filter and 850nm IR filter (these can block all visible light below the wavelength). But my 1080p pinhole camera (my top201 coming in 3 weeks) with one of those IR block (similar to the IR cut switcher) can still detect objects with both the 720nm and 850nm IR filter...

Any tried IR photography with the top201? 10 years ago I owned my IR filters for IR photography where visible light are blocked and only IR light passing thru.. I Have filter from 650nm to 1000nm (noting visible light is from 400nm to 650nm). My question is to what IR range is the sensor of the...

Thanks for making me realize clear can be called a filter too.. it filters the photonic density and reorient the angle of propagation of the bosonic quantum field.

It's more commonly known as double filter. But even as "dual filter".. clear is not a filter. what does it filter.. hmm.. maybe dust? Therefore it must not be called a dual or double filter. Agree? Btw..do you know were top201 get the lens? Is it available separately elsewhere? Because most...

I jus ordered one like it and it's coming in 1 month. I just want to something for now. Why is it called dual filter( most dual filter including one I ordered)a.. are the glasses glued on top of each other. Why is single filter not sufficient, any clue?

Has anyone got a disassembled stock lens of the top201? please take apart the ir filter off the lens and take picture how it looks like (lens and filter).. my order of the unit wil come maybe in 3 weeks time and I have to decide whether the ir filter in the lens can be re used with the pinhole...

Can you please confirm that the attached picture I posted earlier has IR filter really glued on top of the sensor? The supplier doen't know since he just got it elsewhere fully assembled. Why is it colored violet? Second. Where to buy this electronic IR filter (any link or url.. tnx).. why is it...

The following attached picture from an 1080p Hisilicon 3516c.. note the fixed IR filter over the sensor.. where can one buy like that so I can put it over the sensor of the 3518e of the Top201? I need to use pinhole lens which doesn't have built in ir block. Btw. can you take apart you top201...

Does anyone know how long can rechargeable batteries last running the Top201 without direct AC power.. let's say motorcycle lead acid batteries.. or something smaller (or smallest that is possible)?

I spent 2 hours researching all this. I think the *fixed* IR filter is put right on top of the sensor and not part of lens coating. So no matter what lens you use, IR filtering works because the IR film is right on top of sensor. Why do you believe it is in the lens coating in the case of the...

So the Top201 is as reliable in component degradation as full fledged CCTV cams like dahua, hikvision, axis?

can the top201 run 24 hours 7 days a week all year round decade long without burning? Can it last that long? what component of the pcb can get broken first?

i already ordered a top201. id like a confirmation that it can accept pinhole lens like below before i ordered such lens. tnx

Don, found the data sheets of the two in your previous message. So 3518e is really newer than 3518c. Maybe most aliexpres seller sells one based on 3518c is because it's cheaper? anyway why is there many misinformation the 3518c has more features.. for example in...

Say, has anyone successfully replaced the lens in the original top-201 (post #1) with a pinhole lens? See attached picture and below.. would it work? http://s.click.aliexpress.com/e/bDyOtJms

such complication.. lol.. for us consumers who just want to know how many percentage less performance we get from 3518e... hope someone can just give numbers. anyway. what puzzles me.. the original top-201 based on 3518e is only available in www.buyincoins.com located in the US (for only $21)...

The datasheet are inaccessible. I think the summary is that the older 3518e has better sensor (sony HAD) but older chipset than the newer 3518c that uses other brand sensor not so good as sony's? Right? If anyone has seen datasheet comparison of them. Please share them because the site datasheet...

Is the Hi3518e really more advanced than the Hi3518c? But the following URL say otherwise: http://www.mvteamcctv.com/news/What-is-the-difference-between-Hi3518C-and-Hi3518E.html Right now let’s come to notice the Sepecification between the two chipset Hi3518C and Hi3518E(you can study more...
