So charge a range, according to time! This is a rip-off!

Open it up. Have a look at the connections. Just remember what curiosity did to the cat.

So why are you asking us, if even the manufacturer can't fix it? $20 camera is disposable. Nothing to think about. Replace with something better.

Did you try contacting the seller or the manufacturer?

[–] [email protected] 1 points 9 months ago (1 children)

Buy a better one. Preferably wired.

Faster to (dumb) switch them separately.

Missed emails? Don't clients retry?

[–] [email protected] 1 points 10 months ago

Yes, of course. Feel free to explain it better!

The modem device bridges between the local network and the WAN. The physical medium of the WAN is designed to cover longer distances.

Modems used to use audio signaling to send data over phone lines. Nowadays they generally use higher frequencies such as radio signals or optical to send data over radio link, DSL, cable, or fiber media.

The modem device encodes and error checks/corrects, converts and transmits the data -- between the different LAN-WAN protocols / physical layers.

MoDem stands for modulator-demodulator. That implies an audio or RF "baseband" signal being "modulated" (the carrier frequency shifted) to encode the data onto the physical layer.

However, modern modems use DAC/ADC (analog-digital/digital-analog converter) modules to transmit/receive the analog signals and directly convert to/from digital (logic level) signals. They don't need the intermediate step of generating a baseband carrier frequency and then modulating it. Hence the modern modem may actually be an SDR (software-defined radio). SDR can cover a huge frequency range and any encoding/modulation -- defined only by the software!

In fact, some newer radio transceivers use SDR for its flexibility. For example, Flex / Anan radio transceivers. Some designers have repurposed commodity modem chips to create less expensive SDR transceivers. There are now Ham Radio transceivers based on this concept.

Sounds very inexpensive for a home user.

Cellular router with failover.

Aluminum has higher resistance than copper and comes with other issues. Why waste more of the power as heat? Just say NO!
