You always want to see a lit­tle more, here opti­cal instru­ments help us. In the dis­tance — binoc­u­lars, near — a micro­scope. Today we will con­sid­er a dig­i­tal micro­scope with­out a screen from the Chi­nese man­u­fac­tur­er of var­i­ous optics Svbony. The dig­i­tal micro­scope mod­el SM401 con­nects via WiFi to a smart­phone, and via cable to a PC. Comes with a met­al tri­pod.

Pack­ing and scope of deliv­ery

This lot has a fast deliv­ery from a ware­house in the Russ­ian Fed­er­a­tion. Picked up a par­cel from the near­est pos­tom­at. The box with the micro­scope was packed in a dense film. The box itself with­out col­or print­ing. Inside there is a pro­tec­tive plas­tic insert, every­thing is secure­ly placed.

The device is made in Chi­na. Man­u­fac­tur­er’s arti­cle: F9376D. War­ran­ty 1 year.

Svbony SM401 deliv­ery set:

  • Dig­i­tal micro­scope

  • tri­pod base

  • tri­pod stand

  • Rub­ber gas­ket

  • Micro USB cable 1 m

  • PC soft­ware CD

  • Mul­ti­lin­gual user man­u­al (with­out Russ­ian lan­guage)

  • Align­ment card with rulers

The disc in 2022 is a bit bewil­der­ing. But the user man­u­al has a QR code for down­load­ing soft­ware to a smart­phone, and PC soft­ware can be down­loaded from the man­u­fac­tur­er’s web­site (for mod­el SV606). The micro­scope mod­el is still new, so rough­ness is pos­si­ble.

Assem­bly and appear­ance

The micro­scope is deliv­ered unassem­bled, it takes 1 minute to install it on a tri­pod. The tri­pod con­sists of an alu­minum table (dimen­sions 148x77x5 mm) with devel­oped rub­ber legs and an alu­minum rod 150 mm with an arm for a micro­scope. They are thread­ed and secured with a lock­nut. Rack and pin­ion smooth­ly low­ers and rais­es the brack­et.

The micro­scope is made in a cylin­dri­cal body (130x34 mm) made of sil­very plas­tic. Weight 75 g. Since there is no large dis­play, the mod­el is com­pact and inex­pen­sive. On the case there is a ribbed ring for man­u­al focus adjust­ment, there was a place for a small screen (14x6 mm) and a cou­ple of but­tons (turn on and take a pho­to). The micro­scope is fixed in the arm with a pair of screws with a rub­ber end­ing.

The entire assem­bly is quite rigid. Total weight of the micro­scope with tri­pod: 380 g.

At the low­er end of the micro­scope is a cam­era eye with a trans­par­ent acrylic pro­tec­tion. And on the top — a con­nec­tor for charg­ing and con­nect­ing to a PC and a wheel for adjust­ing the bright­ness of the back­light.

The man­u­fac­tur­er did not for­get about the reset but­ton, you can press it with an unfold­ed paper clip. There is no slot for a mem­o­ry card, the con­tent is stored in a smart­phone or PC.

The work of the back­light does not raise any ques­tions, it shines with a cold light, the bright­ness is suf­fi­cient.

The screen shows wel­come words, and after turn­ing on, the charge indi­ca­tion and an active con­nec­tion (WiFi or cable to PC).

The built-in bat­tery charges quick­ly enough, and when work­ing with a PC, charg­ing is also in progress. Dur­ing oper­a­tion, the upper part of the case heats up a lit­tle.


Let’s start with the HiView PC soft­ware. I liked it more than mobile, although it los­es in res­o­lu­tion.

Its main task is to dis­play an image from a micro­scope on a com­put­er mon­i­tor. And you can also:

  • Take photo/video

  • Cal­i­brate the micro­scope for ruler mea­sure­ments

  • Take var­i­ous mea­sure­ments

  • Add cap­tions and tags on the pho­to

When cal­i­brat­ing the micro­scope, the mag­ni­fi­ca­tion is shown. You can rely on these val­ues, they vary from 20 to 220, on aver­age 50 times. Onion cells, as in school exper­i­ments, can­not be seen here.

Com­plete usb cable with­out a fer­rite EMI fil­ter, so inter­fer­ence in the image slips.

Here is a human hair with­out dig­i­tal zoom. And then some pho­tos from a PC with dif­fer­ent mag­ni­fi­ca­tions.

For a video file, the fol­low­ing para­me­ters are: 1280x720 30 fps, bit rate 800 Kbps, Win­dows Media Video 9 codec.

Let’s move on to mobile soft­ware. The pro­gram is called “HVCAMWIFI”, con­nect­ing with a smart­phone via a WiFi net­work. The micro­scope is dis­played with dances, you need to enable geo posi­tion­ing and hit the tam­bourine.

There are even few­er func­tions here than in PC soft­ware, but JPEG pho­tos have a high­er res­o­lu­tion: 1920x1080.


The Svbony SM401 micro­scope can be used for sol­der­ing and mon­i­tor­ing tracks on print­ed cir­cuit boards, sharp­en­ing knives, in numis­mat­ics for check­ing and clean­ing coins, pulling out a splin­ter, and just for fun, for exam­ple, to watch insects.

At the end of the review, we tra­di­tion­al­ly list the pros and cons of the con­sid­ered device.


  • Con­ve­nient met­al tri­pod

  • Wide mag­ni­fi­ca­tion adjust­ment

  • Two types of image out­put


  • Out­dat­ed con­nec­tor for com­mu­ni­ca­tion with PC

  • Inflat­ed mag­ni­fi­ca­tion fig­ures

  • Cable with­out fer­rite fil­ter
