The network infrastructure must therefore be sized to support this traffic without degrading system performance.<\/p>\n\n\n\n<h5 class=\"wp-block-heading\" id=\"h-largura-de-banda-necessaria-para-transmissao-de-video\" style=\"padding-top:var(--wp--preset--spacing--30);padding-bottom:var(--wp--preset--spacing--30)\"><strong>Required Bandwidth for Video Transmission<\/strong><\/h5>\n\n\n\n<p class=\"wp-block-paragraph\">CCTV cameras, especially high-resolution models such as 1080p or 4K, can consume significant bandwidth. The traffic generated by each camera should be estimated considering:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Camera resolution:<\/strong> Higher resolution generally increases the amount of visual data that must be encoded. For example, a 4K stream can require more data than a comparable 720p stream, although actual bitrate also depends on codec, frame rate, scene complexity, and configuration.<\/li>\n\n\n\n<li><strong>Frame rate:<\/strong> A stream configured at 30 frames per second (fps) normally requires more data than a comparable stream at 15 fps. Frame rate should be selected according to the operational need for motion continuity.<\/li>\n\n\n\n<li><strong>Video compression:<\/strong> Codecs such as H.264 and H.265 reduce bitrate and storage requirements relative to uncompressed video.

Beyond traditional DVR and NVR appliances, larger or more demanding systems often use dedicated recording servers managed by a VMS (Video Management System).<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Common recording architectures include:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>NVR (Network Video Recorder):<\/strong> Used in IP-camera systems, an NVR receives and records video streams over the network. It can support remote access and centralized recording for multiple IP cameras.<\/li>\n\n\n\n<li><strong>DVR (Digital Video Recorder):<\/strong> Used with analog CCTV systems, a DVR receives video through coaxial interfaces and digitizes\/records the signals.

The following factors should be considered:<\/p>\n\n\n\n<ol class=\"wp-block-list\">\n<li><strong>Camera resolution:<\/strong> Higher-resolution images, such as 1080p or 4K, can increase storage demand, although actual consumption also depends on codec, frame rate, scene complexity, and bitrate settings.<\/li>\n\n\n\n<li><strong>Frame rate:<\/strong> Higher frame rates, such as 30 fps compared with lower values, generally increase recorded data volume when other parameters remain similar.<\/li>\n\n\n\n<li><strong>Video compression:<\/strong> Codecs such as H.264 and H.265 reduce storage requirements compared with less efficient or uncompressed formats. H.265 can provide greater compression efficiency in suitable implementations, while actual savings depend on encoder implementation and configuration.<\/li>\n\n\n\n<li><strong>Recording retention:<\/strong> Required retention directly affects capacity. Systems retaining video for 30, 60, or more days need proportionally greater storage unless other recording parameters are changed.<\/li>\n\n\n\n<li><strong>Camera count:<\/strong> More cameras increase aggregate recording traffic, processing requirements, and storage capacity.<\/li>\n<\/ol>\n\n\n\n<h4 class=\"wp-block-heading\" id=\"h-solucoes-de-armazenamento\" style=\"padding-top:var(--wp--preset--spacing--30);padding-bottom:var(--wp--preset--spacing--30)\"><strong>Storage Solutions<\/strong><\/h4>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Recording servers:<\/strong> Recording servers can use surveillance-rated drives and<a href=\"\/blog\/o-que-e-raid\/\"> RAID architectures for<\/a> continuous 24\/7 workloads. Drive type, RAID level, controller design, rebuild behavior, throughput, and failure-domain strategy should reflect the required availability and retention.<\/li>\n\n\n\n<li><strong>Cloud storage:<\/strong> Cloud architectures can provide scalability and remote access but depend on connectivity, bandwidth, service availability, cybersecurity, and recurring storage\/egress costs.<\/li>\n\n\n\n<li><strong>Local servers:<\/strong> Dedicated on-premises servers provide direct control over storage, performance, expansion, redundancy, and integration and are common in medium and large deployments.<\/li>\n\n\n\n<li><strong>Edge storage:<\/strong> Some IP cameras can record locally to memory cards or embedded storage.

This can reduce storage but requires careful tuning so relevant activity is not missed.<\/li>\n\n\n\n<li><strong>Scheduled recording:<\/strong> Recording policies can change according to time schedules, such as after-hours operation, when this matches the security requirement.<\/li>\n\n\n\n<li><strong>VMS recording servers:<\/strong> A VMS can combine continuous and event-driven recording, alarm integrations, analytics, retention policies, and centralized configuration.

Resolution should therefore be selected according to the task.<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>720p (HD):<\/strong> Can support general monitoring where fine detail is not a priority, subject to the required scene coverage and image density.<\/li>\n\n\n\n<li><strong>1080p (Full HD):<\/strong> Common in many surveillance applications, but suitability for recognizing or identifying people and license plates depends on image density, geometry, lighting, and scene conditions rather than resolution alone.<\/li>\n\n\n\n<li><strong>4K (Ultra HD):<\/strong> 4K cameras provide a larger pixel count that can be useful for wide scenes or applications requiring greater detail, while also increasing bitrate, storage, processing, and lens-quality requirements.<\/li>\n<\/ul>\n\n\n\n<h4 class=\"wp-block-heading\" id=\"h-lente-e-campo-de-visao\" style=\"padding-top:var(--wp--preset--spacing--30);padding-bottom:var(--wp--preset--spacing--30)\"><strong>Lens and Field of View<\/strong><\/h4>\n\n\n\n<p class=\"wp-block-paragraph\">Lens selection is critical to CCTV performance. Focal length and sensor format determine field of view and image density at the target distance. Lenses may be fixed or varifocal depending on the application.<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Fixed lens:<\/strong> Provides a defined focal length and field of view, suitable where the required scene geometry has already been established in the design.<\/li>\n\n\n\n<li><strong>Varifocal lens:<\/strong> Allows the focal length and field of view to be adjusted within a defined range, providing flexibility during commissioning and scene optimization.<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">The <strong>horizontal field of view<\/strong> should be selected from the operational requirement. Wider views cover more area but reduce pixel density on individual targets, while narrower views concentrate detail on specific zones such as corridors, gates, or entrances.<\/p>\n\n\n\n<h4 class=\"wp-block-heading\" id=\"h-condicoes-ambientais\" style=\"padding-top:var(--wp--preset--spacing--30);padding-bottom:var(--wp--preset--spacing--30)\"><strong>Environmental Conditions<\/strong><\/h4>\n\n\n\n<p class=\"wp-block-paragraph\">The installation environment is another decisive factor. Outdoor equipment must be selected for water, dust, temperature, corrosion, UV exposure, vibration, and other site conditions. An enclosure rating such as <strong>IP66 or higher<\/strong> may be appropriate depending on the exposure.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Indoor areas may require less environmental protection, allowing greater emphasis on imaging performance, form factor, tamper resistance, and architectural integration.<\/p>\n\n\n\n<h4 class=\"wp-block-heading\" id=\"h-analiticos-de-video-embarcados\" style=\"padding-top:var(--wp--preset--spacing--30);padding-bottom:var(--wp--preset--spacing--30)\"><strong>Embedded Video Analytics<\/strong><\/h4>\n\n\n\n<p class=\"wp-block-paragraph\">Many modern cameras support embedded video analytics. Depending on the model and scene, functions may include motion\/object detection, person or vehicle classification, counting, abandoned\/removed-object detection, and specialized recognition functions. Analytics should be specified by measurable use cases and validated under representative conditions rather than assumed from the feature name alone.<\/p>\n\n\n\n\n<h2 class=\"wp-block-heading\" id=\"h-instalacao-do-sistema-de-cftv\" style=\"padding-top:var(--wp--preset--spacing--30);padding-bottom:var(--wp--preset--spacing--30)\">CCTV System Installation<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">With the design completed and components selected, the next phase is physical implementation.
