Mianwali, 110 km from the workshop
In Mianwali, the heat writes the specification
Summers here are harder on equipment than anywhere else we cover. It is not the peak temperature that does the damage but the length of the season: months during which nothing, including the recorder in the back office, ever really cools down.
So a Mianwali quotation is not a Chakwal quotation with travel added. Housings, mounting positions, power supplies and where the recorder lives are all decided differently, and they are priced in from the start rather than offered as an upgrade.

What the heat does, component by component
Useful whoever you buy from. If a quotation for a Mianwali premises does not mention any of the right-hand column, it was written for somewhere cooler.
| Component | What heat does to it | What we specify here |
|---|---|---|
| Cameras | Sealed housings bake in direct sun, and the infra-red cut filter and the sensor both drift as temperature rises. Picture quality degrades before the camera fails outright, so it goes unnoticed. | Mounted under an eave or a purpose-made shroud wherever the building allows it, never on a south-facing wall in open sun by default. |
| The recorder | The component that suffers most and gets the least thought. Recorders are usually put wherever the cable is convenient, which is often a hot cupboard with no airflow. | Sited in the coolest lockable room available, with ventilation above and below the door if it must go in a cupboard. |
| Hard drives | Heat is the main determinant of drive life. A surveillance drive rated for years of continuous writing gets a fraction of that if it runs hot, and it fails without warning. | Surveillance-rated as standard, sized to your retention, and health-checked at every maintenance visit rather than left until playback stutters. |
| Power supplies | Cheap supplies lose regulation as they warm, and the symptom is cameras dropping out at dusk when the infra-red raises the draw — blamed on the camera almost every time. | Distributed rather than one shared unit, mounted out of direct sun, and specified with real headroom over the calculated load. |
| Air conditioning | Units here run most of the year, not seasonally, so servicing intervals that suit Chakwal are too long for Mianwali. Dust and continuous running compound each other. | Serviced twice a year rather than annually, with the condenser coil cleaned properly rather than the filters rinsed and the job called done. |
The same heat that breaks equipment also runs the meter
Mianwali has both an enormous summer cooling load and excellent irradiance, which is a good combination for solar. The catch is that panels themselves lose output as they get hotter, so a system sized from a best-case summer figure will underperform in exactly the month you bought it for.
We size from three months of your actual bills rather than from roof area or an optimistic yield table. It sometimes produces a larger number than a competing quote, and the reason is explained on the page below.
How we size a systemQuestions from Mianwali
- Why does equipment fail faster in Mianwali?
- Sustained heat rather than peak heat. Electronics tolerate a hot afternoon; what shortens their life is weeks of never cooling down, including overnight. Every component in a camera system has a rated operating range, and here they spend months near the top of it.
- Do you charge extra for heat-rated equipment?
- No, because we do not treat it as an upgrade. Outdoor housings, shaded mounting positions and a recorder sited in the coolest available room are how we quote Mianwali jobs by default. Specifying to fail in eighteen months and selling the replacement is not a business we want.
- How far is Mianwali, and what does travel cost?
- 110 kilometres, about two hours each way, PKR 5,000 for a dedicated trip. As with Attock we batch Mianwali work into planned runs, so jobs booked together share one travel charge between them.
- Is solar worth it in Mianwali?
- The irradiance is excellent and the summer load is enormous, which is a good combination. The caution is that panels lose efficiency as they get hotter, so a system sized from an optimistic summer figure will disappoint. We size from three months of your actual bills instead.
Booking together lowers the travel
Mianwali jobs go out on planned runs. Several premises booked on the same trip share one travel charge.
