Hikvision 4117 thermal imaging modification

The BOM (Bill of Materials) is just one component on the adapter board. Other required components include:
a 15*15*1.5mm copper heatsink
, a 0.5mm silicone thermal pad (can be cut to size or 15*15mm is fine)
, M1.4*2.5*2.3mm hot-melt knurled nuts, and
M1.4*4mm flathead Phillips screws.
 
Let's first discuss the features: the back is open, let's call it the "Exploration Edition" for now. It has two USB-C ports, one male and one female, for connecting to a phone or a computer (only one can be connected at a time, not both simultaneously). It has a parameter adjustment switch, allowing you to adjust parameters directly without disassembling the casing. The focus ring is knurled, providing a very good feel.
Precautions:
1. Due to the open back, be careful to prevent water and dust damage.
2. Only one USB port can be connected at a time.
3. Adjust the switch when the power is off; do not move it when the power is on. (Later I found that the OTG and USB switches were basically useless, but I was too lazy to change them.)
4. When the switch is set to CAM or OTG, it can connect to either a computer or a phone; when set to USB, it can only connect to a computer. When the switch is set to DUG, it enters parameter tuning mode, requiring an external network card.
I won't go into detail about disassembling the module; solder the adapter board. The wires are pin-to-pin; just solder them parallel to each other, as shown in the picture .
Note that you shouldn't use wires that are too thick, otherwise they won't fit. After
attaching the heatsink
and soldering, cover the front of the board with a layer of tape to prevent the components above from being knocked off during installation (don't ask me why I'm reminding you) .
Clean off the supports
and then put on the knurled nuts. Install the motherboard
and then install the adapter board on top. This step requires some patience; be careful not to damage the components below, which is why you use tape.
The rest is simple: install the ribbon cable. Note that there are two layers of foam at the shutter switch on the camera; remove them.
 
Put the cover on and screw it in.
Use a utility knife to remove the adhesive from the lens, cleaning both sides until you can screw the lens in.
Screw on the lens cap, and enjoy!
