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.
