The practical answer has three layers: thermal cameras on the fence that detect anything warm approaching, day or night; PTZ cameras that identify what was detected; and a network video recorder (NVR) with network links and backup power that keep video available to a control room or remote operator.

It captures the thermal infrared radiation every object emits according to its temperature. A person or vehicle therefore stands out clearly against the ground and fence even in total darkness, and the fence line needs no lighting. That makes thermal the main detection tool on large sites.<\/p>\n<p>Its limits matter too: a thermal image cannot identify a face or read a number plate. Thermal cameras are therefore usually linked to a PTZ camera. When the thermal camera raises an alarm, the PTZ turns to the spot automatically and gives a colour or infrared image with optical zoom. Examples on the AZEIDK site include the <a href=\"\/en\/sa\/products\/dahua-8mp-4k-ai-40x-optical-zoom-starlight-ir-ptz-ip-camera-model-dh-sd8a840-hnf-pa\/\">Dahua DH-SD8A840-HNF-PA PTZ camera<\/a> and the <a href=\"\/en\/sa\/products\/hikvision-ds-2sf8c442mxg-elw26-ptz-camera\/\">Hikvision DS-2SF8C442MXG-ELW26 PTZ camera<\/a>.<\/p>\n<p>When selecting a thermal camera, check three points in the official datasheet:<\/p>\n<ul>\n<li><strong>Detection range:<\/strong> it depends on the lens, sensor resolution and target size, and differs for people and vehicles. Manufacturers publish it per lens.<\/li>\n<li><strong>Built-in analytics:<\/strong> line crossing and intrusion with human and vehicle classification cut false alarms. Dahua, for example, describes several filtering strategies in its perimeter solution to reduce the effect of animals and the environment.<\/li>\n<li><strong>Environmental rating:<\/strong> dust and water protection and the operating temperature range must suit the site.<\/li>\n<\/ul>\n<p>We do not give detection distances or prices here because they vary by model and lens and are fixed after a site survey.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-288d606 elementor-widget elementor-widget-text-editor\" data-id=\"288d606\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"text-editor.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t\t\t<h2>When are standard night cameras enough instead of thermal?<\/h2>\n<p>At gates and around equipment rooms and stores, where distances are short and lighting is possible, fixed cameras with ColorVu or Starlight night technology are usually enough.
