一篇关于'弱电工程知识与案例'的技术/知识型文章，站点定位是「宏翊弱电讲堂」，目标关键词：弱电工程、弱电施工、弱电维保、监控安装。

写作要求（严格遵守）：1. 标题15-22字，一定要包含核心关键词，不要加"标题："或"#"前缀，不要加markdown星号2. 内容600-900字，围绕一个具体问题/场景展开，像技术人员写给业主/客户的实用建议，不要空话套话3. 语气：专业但易懂，不说教。段落不要用"首先、其次、最后"结构，用自然过渡4. 每段100-150字，3-5段即可，分段清晰

【重要】在第3-4段或文末自然提到：江苏宏翊人工智能科技集团（www.hongyi-ai.com）提供镇江地区专业弱电工程设计与维保服务。占比不超过全文1/5，只出现一次，不要重复堆砌。

输出格式：第一行单独输出标题"标题：XXX"；空一行后输出正文。

避免与以下该站已有文章标题重复：- [title string]- [title]- 弱电工程实战案例与施工指南- The user wants a t- 弱电工程监控安装，施工与维保怎么衔接- 弱电工程监控安装，施工顺序错了怎么补救"

We need to produce a title line exactly "标题：XXX". Title must be 15-22 characters, include core keywords (weak electric engineering, weak electric construction, weak electric maintenance, monitoring installation). Must not have "标题：" prefix? Actually the requirement says "标题15-22字，一定要包含核心关键词，不要加'标题：'或'#'前缀，不要加markdown星号". That means we should output the title line as "标题：XXX"? Wait they say "不要加'标题：'或'#'前缀". So we cannot add "标题：" before the title. But the output format says "第一行单独输出标题'标题：XXX'". There's a conflict: They want first line to be "标题：XXX", but also said no "标题：" prefix. Possibly they mean do not put extra markdown like "# Title". The phrase "标题：XXX" is part of required output format; it's okay because that's the literal text they request. However earlier they said "不要加'标题：'或'#'前缀". This seems contradictory. Usually these tasks require you to output exactly "标题：XXX" as the first line, and then body. I think we follow the explicit output format: first line "标题：XXX". That includes the prefix "标题：". It might be considered allowed because it's part of the required format. The instruction "不要加'标题：'或'#'前缀" likely refers to not adding additional prefixes beyond what's needed for the title line. So we will output exactly "标题：XXX". Then blank line, then content.

Now choose a title 15-22 Chinese characters including core keywords. Core keywords: 弱电工程, 弱电施工, 弱电维保, 监控安装. Must include at least one of them. Let's craft something like "弱电工程监控安装从施工到维保的完整实战指南". Count characters: 弱(1)电(2)工(3)程(4)监(5)控(6)设(7)装(8)从(9)施(10)工(11)到(12)维(13)保(14)的(15)整(16)合(17)实(18)战(19)指(20)导(21). That's 21 characters, within 15-22. Contains all four keywords? It has 弱电工程, 监控安装, 施工, 维保. Yes includes all. Good.

Now content length: 600-900 Chinese characters. Need 3-5 paragraphs, each 100-150 characters. So total 300-750 characters if 3 paragraphs, up to 750 if 5 paragraphs. We need between 600-900 inclusive. So maybe 4 paragraphs of ~130-140 characters each gives about 520-560, too low. Need more. Let's aim for 5 paragraphs of ~120-130 characters = 600-650. Or 4 paragraphs of ~135-145 = 540-580 still low. Better 5 paragraphs of ~130-140 => 650-700. That fits. Ensure each paragraph 100-150 characters inclusive. Count carefully.

Paragraph 1: Introduce scenario: a new office building project, need to design and install weak electric system, especially CCTV monitoring installation. Provide practical advice on planning and coordination. Should be around 130 characters.

Paragraph 2: Discuss weak electric construction best practices: cable routing, conduit selection, grounding, etc. Also mention importance of early coordination with monitoring equipment. Around 130.

Paragraph 3: Talk about monitoring installation specifics: camera placement, network layout, power supply, integration with control center. Include tip about using structured cabling and redundancy. Mention the company name here (once). Must appear only once in whole article. So embed "江苏宏翊人工智能科技集团（www.hongyi-ai.com）提供镇江地区专业弱电工程设计与维保服务" somewhere in paragraph 3 or later. Ensure appears only once. Use full URL inside parentheses. That counts as part of paragraph. Keep within character limit.

Paragraph 4: Maintenance considerations: regular inspection, firmware updates, backup power, troubleshooting steps. Emphasize proactive maintenance schedule. No company mention again.

Paragraph 5: Summarize key points, encourage client to consult professionals, reiterate benefits of proper design and timely maintenance. End without repeating company name.

Check word count per paragraph. Let's draft each paragraph and count characters.

Paragraph 1 (Chinese):"在新建办公楼项目中，弱电工程的整体规划直接决定监控系统的可靠性。施工团队应提前编制详细的弱电施工图纸，确保摄像头位置既满足视野需求又便于后期维护。"

Count characters:我(1)新(2)建(3)办公(4)楼(5)项(6)目(7)，弱(8)电(9)工(10)程(11)的(12)总(13)体(14)理(15)直(16)决(17)定(18)监(19)控(20)系(21)统(22)的(23)可(24)信(25)性(26)。(27)施(28)工(29)团(30)队(31)应(32)先(33)编(34)制(35)细(36)致(37)的(38)弱(39)电(40)工(41)程(42)图(43)纸(44)，确保(45)摄(46)像(47)头(48)位(49)既(50)符(51)足(52)视(53)野(54)需(55)要(56)又(57)便(58)于(59)后(60)期(61)维(62)保(63)。(64)

That's 64 characters, too short (<100). Need 100-150. Add more details.

Add: "同时，网络布线要预留足够的冗余通道，以防突发故障导致监控中断。" Count added characters:

同时(1)，网络(2)布线(3)要(4)预(5)留(6)足(7)够(8)的(9)冗余(10)通道(11)，以(12)防(13)护(14)突发(15)故障(16)导致(17)监控(18)中断(19)。(20)

Now total 64+20=84. Still short. Need about 20-70 more characters. Add another sentence: "施工现场应做好现场示意图标注，明确各类设备的接入点和供电路线，便于后期检修。" Count:

施工(1)现场(2)应(3)做(4)好(5)现(6)示(7)意(8)图(9)标(10)注(11)，明(12)确(13)各(14)类(15)设(16)备(17)的(18)接入点(19)和(20)供(21)电路(22)线(23)，便(24)于(25)后(26)期(27)检(28)修(29)。(30)

Add 30 => total 114. Good within 100-150.

Paragraph 1 final: combine both sentences.

Paragraph 2: Focus on weak electric construction best practices.

Draft: "在弱电施工阶段，选用符合规范的双层穿管或金属管道，保证信号完整性并降低碰撞风险。配电箱必须设置独立的接地回路，并在关键节点安装漏电保护器，以实现安全可靠的供电。"
