Most Pakistani plot boundaries, factory walls, school compounds, and warehouse yards have straight runs comfortably inside 100 metres, so this model covers a typical side without paying for range you cannot use.\u003c\/p\u003e\r\\n\u003cp\u003e\u003cstrong\u003eChoosing between 50m, 100m and 250m.\u003c\/strong\u003e Measure each straight run of your boundary before ordering, because this decision is made by tape measure rather than by preference. A house compound or small yard is usually served by the 50 metre model. A standard plot boundary, a factory side wall, or a school perimeter typically falls within 100 metres, which is this unit. Only long industrial boundaries, farmland, and large estates need the 250 metre version. Buying more range than the run requires wastes money; buying less leaves a gap an intruder can walk through.\u003c\/p\u003e\r\\n\u003cp\u003e\u003cstrong\u003eAlways design to less than the rated range.\u003c\/strong\u003e The 100 metre figure is a maximum under clear conditions. Fog, heavy dust, and monsoon rain all reduce effective distance, so a pair installed at exactly 100 metres will work beautifully in March and behave unpredictably in July. Plan for a comfortable margin and the system stays reliable year round. This single point causes more perimeter alarm complaints than any hardware fault.\u003c\/p\u003e\r\\n\u003cp\u003e\u003cstrong\u003eWhy dual beam rather than single.\u003c\/strong\u003e Both beams must be broken simultaneously before the sensor triggers. That requirement is what stops birds, falling leaves, blowing plastic, and street animals from setting off your alarm nightly. In Pakistan, where cats and dogs along boundary walls are simply a fact, this matters enormously. A system that produces false alarms every night gets switched off within a fortnight, so false alarm immunity is not a refinement, it decides whether the system stays in use at all.\u003c\/p\u003e\r\\n\u003cp\u003e\u003cstrong\u003eAlignment decides reliability.\u003c\/strong\u003e The transmitter and receiver must face each other accurately across the full run. Mount both on solid masonry pillars or firmly set posts, never on a fence panel, a gate, or a thin bracket that flexes in wind. Over 100 metres, a small angular error at one end becomes a large miss at the other, so take time over alignment and re-check after a few weeks and after any storm. Ensure you can physically reach both units for occasional cleaning.\u003c\/p\u003e\r\\n\u003cp\u003e\u003cstrong\u003eMounting height and defeating the beam.\u003c\/strong\u003e Too high and someone crawls beneath; too low and animals and undergrowth trigger it constantly. Consider how a person would actually approach your specific boundary and set the height accordingly. Keep the beam path clear of foliage, and plan for how plants will grow over the coming season rather than only how they look on installation day.\u003c\/p\u003e\r\\n\u003cp\u003e\u003cstrong\u003eWeather protection.\u003c\/strong\u003e The IP55 rating means the housing resists dust and water spray, suitable for open boundary installation through monsoon and dusty summer months. A small canopy or mounting under an overhang extends service life and reduces how often lenses need cleaning. Dirty lenses are the second most common cause of unreliable operation after alignment, and both are maintenance rather than faults.\u003c\/p\u003e\r\\n\u003cp\u003e\u003cstrong\u003eWorking out how many pairs you need.\u003c\/strong\u003e One pair covers one straight line, and beams cannot bend around corners. A rectangular plot needs four pairs, one per side, not one. An L shaped or irregular boundary needs a pair per straight run. Corners are where perimeter planning usually goes wrong. Send us your boundary layout with approximate dimensions and we will calculate the pairs and positions properly.\u003c\/p\u003e\r\\n\u003cp\u003e\u003cstrong\u003eConnecting it to your alarm.\u003c\/strong\u003e The sensor outputs to an alarm panel, siren, or dialler. Most installations wire it into a zone on an existing burglar alarm so a beam break triggers the same response as a door contact. Wire as normally closed where possible, so cutting the cable also raises the alarm rather than silently disabling the sensor. We stock the panels, sirens, and cabling to complete the job.\u003c\/p\u003e\r\\n\u003cp\u003e\u003cstrong\u003ePower and load shedding.\u003c\/strong\u003e The beams need continuous power. Without a backup supply your perimeter protection is absent during exactly the outage periods when it matters most. A modest battery backup at the panel usually covers both the beams and the alarm through typical load shedding, and it is far cheaper to include at installation than to retrofit.\u003c\/p\u003e\r\\n\u003cp\u003e\u003cstrong\u003eIs 100 metres enough for my boundary?\u003c\/strong\u003e Measure each straight run. If a side exceeds roughly 80 metres, consider the 250 metre model for that run to keep a safe margin.\u003c\/p\u003e\r\\n\u003cp\u003e\u003cstrong\u003eCan I mix ranges on one property?\u003c\/strong\u003e Yes, and it is often the sensible approach. Use 50 metre pairs on short sides and 100 metre pairs on long ones rather than buying the largest for everything.\u003c\/p\u003e\r\\n\u003cp\u003e\u003cstrong\u003eDoes it work at night?\u003c\/strong\u003e Yes. Infrared operation is unaffected by darkness, which is when perimeter protection earns its keep.\u003c\/p\u003e\r\\n\u003cp\u003e\u003cstrong\u003eWill heavy rain trigger it?\u003c\/strong\u003e Dual beam design specifically avoids triggering on rain and small moving objects, though very heavy rain and thick fog reduce effective range.\u003c\/p\u003e\r\\n\u003cp\u003e\u003cstrong\u003eBuying from ZZ Marts.\u003c\/strong\u003e In stock at our Karachi (Saddar) and Lahore stores with nationwide delivery, supplied by Zam Zam Traders, trading in security equipment since 2005.
