Is recording down or only live viewing? Is the issue permanent or intermittent? Scope definition usually narrows the fault much faster than changing equipment at random.<\/p>\n<h2>1. Camera is Offline or not visible<\/h2>\n<h3>Possible causes<\/h3>\n<ul>\n<li>Power or PoE loss.<\/li>\n<li>Damaged cabling or poor termination.<\/li>\n<li>IP conflict or changed camera address.<\/li>\n<li>Switch-port or VLAN issue.<\/li>\n<li>Incorrect credentials in the NVR\/VMS.<\/li>\n<\/ul>\n<h3>What should be checked?<\/h3>\n<p>Check switch link status, PoE status, IP reachability, cable and RJ45 termination, then NVR\/VMS configuration. If several cameras fail together, inspect the shared switch, uplink or power source before assuming multiple camera failures.<\/p>\n<h2>2. Live View works but there is no recording<\/h2>\n<ul>\n<li>Review recording schedule or event-recording rules.<\/li>\n<li>Check HDD\/Storage health, errors and available capacity.<\/li>\n<li>Confirm the channel is enabled for recording.<\/li>\n<li>Verify date and time because incorrect synchronization can place footage under a different timestamp.<\/li>\n<\/ul>\n<h2>3. Video freezes, drops or is delayed<\/h2>\n<p>IP CCTV interruptions can relate to <strong>Bandwidth, Bitrate, Packet Loss, Uplink capacity, PoE stability or Storage throughput<\/strong>. Randomly lowering image quality is not a root-cause fix; identify the bottleneck first.<\/p>\n<p>For larger networks, see <a href=\"https:\/\/aytechnology.org\/en\/enterprise-network-fiber-infrastructure-egypt\/\">Enterprise Network &#038; Fiber Infrastructure<\/a> and the <a href=\"https:\/\/aytechnology.org\/en\/poe-cctv-system-design-guide\/\">PoE CCTV Design Guide<\/a>.<\/p>\n<h2>4. Poor night image or IR reflection<\/h2>\n<ul>\n<li>Clean the lens and protective cover.<\/li>\n<li>Check for nearby surfaces reflecting IR, such as a wall or glass.<\/li>\n<li>Review camera angle and scene lighting.<\/li>\n<li>Adjust Exposure, WDR and IR settings according to the model and environment.<\/li>\n<\/ul>\n<h2>5. Mobile app works locally but not remotely<\/h2>\n<p>This normally concerns <strong>external connectivity<\/strong>, not recording itself. Check internet connectivity and P2P\/Cloud status or the VPN\/remote-access design. Do not expose CCTV devices directly to the public internet or open ports without an appropriate security assessment.<\/p>\n<h2>6. Cameras disconnect at night when IR turns on<\/h2>\n<p>Higher power consumption when IR activates can expose a weak <strong>PoE Power Budget<\/strong>, power supply or voltage problem. If several cameras fail at the same time, review the switch power budget, supply and UPS before replacing cameras.<\/p>\n<h2>7. NVR is slow or Playback is unstable<\/h2>\n<ul>\n<li>Compare total incoming bandwidth with the NVR specification.<\/li>\n<li>Check disk health and storage capacity.<\/li>\n<li>Review stream count, resolution, bitrate and frame rate.<\/li>\n<li>Verify LAN stability when playback is performed over the network.<\/li>\n<\/ul>\n<h2>Quick troubleshooting table<\/h2>\n<table style=\"width:100%;border-collapse:collapse\">\n<thead>\n<tr>\n<th style=\"padding:10px;border:1px solid #e2e8ee\">Symptom<\/th>\n<th style=\"padding:10px;border:1px solid #e2e8ee\">Start by checking<\/th>\n<\/tr>\n<\/thead>\n<tbody>\n<tr>\n<td style=\"padding:10px;border:1px solid #e2e8ee\">Camera Offline<\/td>\n<td style=\"padding:10px;border:1px solid #e2e8ee\">Power\/PoE \u2192 Cable \u2192 IP \u2192 Switch \u2192 NVR<\/td>\n<\/tr>\n<tr>\n<td style=\"padding:10px;border:1px solid #e2e8ee\">No Recording<\/td>\n<td style=\"padding:10px;border:1px solid #e2e8ee\">Schedule \u2192 HDD\/Storage \u2192 Time \u2192 Channel settings<\/td>\n<\/tr>\n<tr>\n<td style=\"padding:10px;border:1px solid #e2e8ee\">Video drops<\/td>\n<td style=\"padding:10px;border:1px solid #e2e8ee\">Bitrate \u2192 Packet Loss \u2192 Uplink \u2192 Storage<\/td>\n<\/tr>\n<tr>\n<td style=\"padding:10px;border:1px solid #e2e8ee\">Poor night image<\/td>\n<td style=\"padding:10px;border:1px solid #e2e8ee\">Lens \u2192 IR reflection \u2192 Lighting \u2192 Exposure<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<h2>When is a technical site assessment better than trial-and-error?<\/h2>\n<p>When the fault repeats, affects several devices, spans multiple switches or buildings, or involves storage, PoE or fiber, a structured assessment with documented tests and results is more appropriate than repeated component replacement.<\/p>\n<p style=\"padding:16px;background:#f7f9fb;border-left:4px solid #f4ad38;border-radius:10px\"><strong>For companies and projects:<\/strong> see <a href=\"https:\/\/aytechnology.org\/en\/service\/cctv\/\">Business CCTV Services<\/a> and <a href=\"https:\/\/aytechnology.org\/en\/enterprise-cctv-system-design-egypt\/\">Enterprise CCTV System Design<\/a>, or <a href=\"https:\/\/aytechnology.org\/en\/enterprise-project-request\/?ay_service=cctv-ai\">send a project\/fault review request<\/a>.
