Real-time inventory sync between two stores starts with separating cloud software, HQ purchase-sales-inventory systems, and each store’s own bookkeeping. Networking handles cross-store access while software handles stock deduction, plus a tested checklist for sales and returns.

A friend of mine who runs a processing factory hired a technician not long ago to make the factory’s surveillance cameras viewable “on his phone.” The technician walked around, then quoted RMB 3,800: replace all eight cameras and add a new recorder. He showed me the quote and asked whether it was worth it. I…

Last week a client who runs a restaurant chain asked us a very direct question: “My daily takings all run over your networking channel — can you see them from your back end?” Fair question. It is also the one most owners keep to themselves and never voice before signing up for multi-site networking. So…

The finance staff sits at headquarters; the orders sit at the branch. Every evening, a branch clerk photographs the sales slips and sends them over WeChat, and the headquarters accountant copies them into the system one by one, phone in hand. This isn’t a joke — it’s daily reality for many owners of two stores.…

First, a word on who we are: Yuxinan is a multi-site networking product made by Siwenlide, so we have a stake in this article. This is the question business owners ask most often before deploying multi-site networking: “Once it’s installed, will the internet in my store slow down? Will checkout lag?” The answer is no.…

First, a disclosure: Yuxinan is a multi-site networking product made by Siwenlide, and we are a stakeholder in this article. So this piece won’t take swipes at competitors—it just lays out the differences between the two things clearly, so you can judge for yourself which one fits your case. In one sentence: an ordinary VPN…

There is only one sound approach to accessing HQ NAS and ERP: expose nothing to the public internet, and let branch and home computers reach the HQ intranet instead. Port forwarding and direct remote desktop connections are traps today. This article lays out the right approach, how each role should connect, the security math, and…

Whether multi-site networking is stable isn’t decided by marketing concepts. It comes from three layers stacked together: the tunnel layer, relay fallback, and the broadband foundation. This article breaks all three down, so you can judge whether a networking solution is reliable even without technical knowledge, and then verifies it by running the free version…

The hard part of centralized surveillance isn’t the video wall, it’s the network: first connect the branches and headquarters into a single network, then run your surveillance platform just as you would locally. Port forwarding is a hotspot for camera brute-force attacks; mind the bandwidth math of substreams for live view and main streams for…

Don’t buy equipment yet: POS systems come in two types — cloud SaaS and on-premises servers — and in half of all cases you don’t need any networking at all. A 30-second test, three connection options for on-premises setups, and an outage contingency checklist.

No. Requiring a public IP is an approach from over a decade ago; today’s networking uses P2P direct connections plus cloud relay, so it works even when both sites are on private networks. Three scenarios to match your case, plus a self-check method.

Let’s get one thing straight up front: Yuxinan is a multi-site networking product from Siwenlide, and we are a stakeholder in this article. So this article does no rankings; it answers just one question that many people search for but few explain clearly: is there really such a thing as free multi-site networking? Yes, and…
