In September 2019, the head of a precision manufacturing factory in Shenzhen’s Bao’an District came to us. Their office building had just been expanded, but the low-voltage systems were a mess: surveillance had blind spots, access control existed in name only, and booking a meeting room for a video call meant joining a queue. I went to the site with our engineers to survey it, and the problem was not simply aging equipment, there had been no overall planning at all. Over two months we redesigned the structured cabling, replaced the entire surveillance and access control systems, and deployed the meeting room systems in a single pass. At acceptance the client said one thing: “So this is how low-voltage work can be done.” That project became our first complete case in Shenzhen, and the start of bringing our “full-package” model from Beijing to South China.
Why Shenzhen Businesses Choose Siwenlide for Low-Voltage & Cabling Projects
Business owners in Shenzhen are pragmatic as a rule. What they want is not the lowest price but someone who takes full responsibility for a low-voltage project from design through maintenance, instead of juggling seven or eight vendors each covering one small part. We have worked in Beijing for 14 years and served more than 300 enterprise clients, and along the way we built a mature full-package model. We have transplanted that model directly to Shenzhen, so local companies can enjoy the same convenience of “one contract that covers everything.”
- No template-based design: the first step in a low-voltage project is planning, and planning has to be based on the client’s actual environment. We do not produce template proposals made of a “standard server room drawing plus an equipment list.” We send engineers to the site to measure, draw and advise. In 2018, when we cabled a logistics park in Shunyi, the client initially asked only for networking in the office area. We recommended including the warehouse in the overall plan. Six months later, when the client expanded the warehouse, the cabling design was reused directly, saving the cost of digging it all up again.
- Local service response: Shenzhen clients share one trait, when something goes wrong they want it fixed right away. We currently provide a service model that combines remote and on-site support: faults that can be handled remotely are responded to within 4 hours, and anything that cannot be resolved remotely gets an on-site visit within three days. This response speed has been proven many times with our Beijing clients, and we are confident we can match it in Shenzhen.
- Documented, standards-based installation: Siwenlide is certified to ISO 9001 and ISO 20000, and every project comes with complete as-built documentation, including cabling labels, system topology diagrams and equipment lists. That documentation is a genuine asset for later operations and expansion. We do not simply hand the client a pile of equipment and call it done.
What We Have Done in Shenzhen
When a new-energy vehicle parts factory in Shenzhen’s Nanshan District came to us, phase one had to cover the entire production building and office area. The workshops required 68 surveillance points with 90-day video retention; the access control system had to connect to the factory’s existing attendance system; and the meeting rooms needed professional audio and remote video equipment. The biggest challenge was that the factory could not stop production during construction. We adopted a phased construction plan and carried out cutovers on weekends and night shifts, and in the end we delivered five days ahead of the contract date. The company has now also entrusted us with phase two: parking barrier gates and warehouse expansion.
Another client is an 80-person internet finance company in Shenzhen’s Futian District, which needed a full low-voltage package from scratch when it moved into new offices. The client stressed the need for a “professional network,” because its business involves the transmission of sensitive data. We produced a complete network segmentation design, dividing the network into three VLANs for office, servers and guests, which ensures both secure isolation and ease of later operations. From mobilization to delivery the project took only 22 working days. When the client adjusted the workstation layout at short notice midway through, we re-optimized the cabling design without delaying the overall schedule. The client’s IT manager later told me that they had approached two other vendors for proposals, and both simply “measured a few dimensions and quoted a price,” while only we provided a detailed network architecture diagram.
Core Deliverables of a Low-Voltage & Cabling Project
A low-voltage project is not simply “installing a few cameras and running a few network cables.” A genuinely professional delivery should cover the following systems, with interoperability between them:
- Structured cabling system: fiber optic installation, copper cabling (Cat5e/Cat6), data outlet deployment, server room fit-out and rack installation. This is the “circulatory system” of the entire low-voltage network, and poor planning turns later expansion into a nightmare.
- Video surveillance system: mainstream brands such as Hikvision and Dahua, 2MP/4MP HD cameras, dual backup with local and cloud storage, remote viewing through a mobile app, and night-vision capability selected to suit the scenario.
- Access control system: supports card, PIN, fingerprint and face recognition, integrates with attendance systems, manages permissions down to each door and each person, and raises real-time alerts when a door opens abnormally.
- Meeting room systems: specified according to room size and purpose. Small rooms get wireless screen sharing plus an interactive meeting panel; large rooms get professional audio plus remote video conferencing terminals. The options combine flexibly.
- Parking barrier gates: integrated license plate recognition, with monthly pass management, temporary vehicle billing and unattended operation, and integration with the company’s access control system for a single-card solution.
- Network equipment deployment: enterprise routers, core switches, access switches and wireless APs, mainly from Huawei, H3C and Cisco, backed by a complete network architecture design.
Price Reference (Shenzhen)
There is no standard price for a low-voltage project, but a reference range can be given based on company size. The figures below are based on mainstream-brand equipment and standard construction conditions; an accurate budget for a specific project requires an on-site survey by our engineers. Our commitment: no hidden costs after the contract is signed, and any additional items require the client’s written confirmation.
| Company Size | Data Outlets | Surveillance Points | Access Control Units | Meeting Room Systems | Reference Price |
|---|---|---|---|---|---|
| 50-100 staff | 150-200 | 30-50 | 5-10 | 1 | RMB 180,000-350,000 |
| 100-300 staff | 400-600 | 80-150 | 20-40 | 3-5 | RMB 450,000-800,000 |
| 300+ staff | 800+ | 200+ | 50+ | 5+ | Quotation on request |
The prices in the table are package prices covering equipment plus installation; they do not include renovation, demolition or alteration work. On equipment selection: if the client specifies premium brands (such as Bosch audio systems or Honeywell access control), prices rise by 20%–30%; if the client accepts domestic brands with equivalent specifications, the project can be kept within budget. We do not engage in cutthroat low-price competition, but we will help clients find the optimal configuration within their budget.
Frequently Asked Questions
Q: What qualifications are required for project installation in Shenzhen? Can you take on such projects?
A: Low-Voltage & Cabling Projects must be undertaken by companies holding the relevant construction qualifications. Siwenlide holds a professional contracting qualification for intelligent building systems, and can legally and compliantly take on all types of low-voltage and cabling projects. Before mobilization we provide copies of our qualification certificates; upon completion we provide acceptance reports and as-built documentation.
Q: Our office building has already been renovated — will the installation damage the walls?
A: That depends on the site conditions. In already-renovated spaces, we prioritize surface-mounted trunking and cable trays to minimize damage to the walls. For cabling that must be concealed, we use dust-free channeling equipment and repair the wall surface once the work is done. For companies concerned about their interiors, we recommend incorporating low-voltage planning into the renovation stage itself — later modifications will cost far less.
Q: Is there a warranty after the project is completed? Who do we contact if something goes wrong?
A: All projects come with a warranty of at least one year; during the warranty period, failures not caused by human damage are repaired free of charge. After the warranty expires, an annual operations & maintenance contract can be signed, covering scheduled inspections, fault response, spare-parts replacement and other services. O&M pricing depends on company size and equipment count; for a company of 50–100 people it is roughly RMB 6,000–12,000/month.
Q: Can existing equipment be reused? For example, can cameras installed earlier still be used?
A> A site assessment is required. If the existing equipment models are not obsolete and image quality meets the standard, they can be incorporated into the design of the new system, and we charge only for system integration and commissioning. One client had bought a batch of cameras from another supplier and the project stalled before installation was finished; we helped connect that batch of equipment to the new system, saving nearly RMB 30,000.
