echnical/knowledge article about "弱电工程报价与方案参考" (Weak electrical engineering quotation and scheme reference). The site positioning is "弱电工程报价". Target keywords: 弱电工程报价, 监控安装报价, 弱电施工价格.

Requirements:

1. Title: 15-22 characters, must include core keyword(s). No "标题:" or "#" prefix, no markdown stars. So just the title line alone, e.g., "弱电工程报价与监控安装方案实战指南". Count characters: Chinese characters count as one each? Usually yes. Let's count: 弱(1)电(2)工(3)报(4)价(5)与(6)监(7)控(8)设(9)装(10)方案(11)实(12)战(13)指(14)导(15). That's 15 characters, meets 15-22. Contains core keyword "弱电工程报价". Good.

2. Content length: 600-900 Chinese characters. Must be around that range. We'll aim for ~750 characters.

3. Tone: professional but easy to understand, not lecturing. Paragraphs should not start with "首先、其次、最后". Use natural transitions. Each paragraph 100-150 words, 3-5 paragraphs total. So we need 3 or 4 paragraphs. Each paragraph 100-150 words. Let's target 4 paragraphs of ~120-130 words each = total ~480-520, too low. Need 600-900 total. So maybe 3 paragraphs of ~200-250 each gives 600-750. Or 4 paragraphs of ~180 each gives 720. Let's do 4 paragraphs, each 180-200 words => total ~720-800, within range.

Paragraph 1: Introduce scenario: client asks for quote for weak electrical system including monitoring installation. Emphasize importance of accurate quoting. Mention typical pitfalls like ignoring hidden costs, overestimating labor, etc. Include mention of macro technology free consultation later in paragraph 3 or end.

Paragraph 2: Provide concrete calculation method for monitoring installation price: list components (cameras, cabling, control panel, wiring, installation time), cost per item, labor rates, equipment rental. Show example numbers. Also talk about how to avoid double counting.

Paragraph 3: Discuss how to compare quotes from multiple contractors, focusing on scope, warranty, service level. Suggest using standardized checklist. Then insert the required phrase: "宏翊科技提供免费弱电工程咨询与报价服务，详询18168689199". Ensure it appears once, not repeated. It can be placed at end of paragraph 3 or after. Must be within overall text, not exceed 1/5 of total characters. That's fine.

Paragraph 4: Summarize best practices: get detailed breakdown, verify material quality, confirm timeline, ask for references. Encourage clients to request transparent pricing. End with call to action maybe referencing contact again? But only one occurrence allowed; already used in paragraph 3. Should not repeat. So final paragraph ends without repeating.

Check word counts per paragraph.

Paragraph 1 (approx 180 chars):"在大型商业综合体的改造项目中，业主常要求快速出具弱电工程报价，以便在预算范围内完成监控安装和配电系统的整合。很多初次接触的报价往往只列出设备采购费用，却忽略了现场布线、接线调试以及运维保养的隐性成本，这会导致后期返工频繁。通过一次系统化的报价审查，既能锁定总造价，又能提前识别潜在的成本失控点，为后续施工提供可靠依据。"

Count characters: Let's count manually. Chinese characters count includes punctuation? Typically punctuation counts as separate tokens but still part of string. We'll approximate. I'll write out and count.

So approx 156 characters. That's okay (within 100-150? Actually requirement says each paragraph 100-150 words. This is slightly above 150 (156). Might be considered too long. We need 100-150 inclusive. So we need to trim down to <=150. Let's reduce some sentences.

Rewrite paragraph 1 shorter: maybe 130 characters.

New version:

"在大型商业综合体改造中，业主常要求快速出具弱电工程报价，以便在预算范围内完成监控安装和配电系统整合。很多初次接触的报价只列出设备采购费用，却忽略现场布线、接线调试及运维保养的隐性成本，这会导致后期返工频繁。通过一次系统化的报价审查，可锁定总造价并提前识别潜在风险，为后续施工提供可靠依据。"

145 characters, within 100-150. Good.

Paragraph 2: Provide calculation method for monitoring installation price. Aim ~170 characters.

Draft:

"监控安装报价应从硬件、布线、控制柜及人工四个维度拆解。摄像头单价一般在3000至5000元之间，取决于分辨率和防护等级；布线费用主要包括走线材料、接线盒和信号线，按米计费约30元/米；控制柜租赁或自建成本约8000元不等；人工工时按每小时150元计算，现场布线、
