Karachi Ki Barish Aur Load Shedding: CCTV System Ko Kharab Hone Se Kaise Bachayein

Karachi mein har saal barish ka system aur bijli ka system dono aik saath imtihan lete hain. Monsoon ke doran hamari service calls teen guna barh jati hain, aur mazay ki baat yeh hai ke 90% cases mein camera bilkul theek hota hai — masla cable ke joint, junction box mein pani, ya voltage ke jhatke se jali hui power supply hoti hai.

Agar aap ne CCTV system par 40–50 hazar kharch kiye hain to inhi chhoti cheezon ka khayal rakh kar aap us ki umar do guna kar sakte hain.

1. Pani hamesha cable ke joint se andar jata hai, camera se nahi

IP66 rated camera khud waterproof hota hai. Lekin jahan BNC connector ya power jack juda hota hai, wo point khula rehta hai. Barish ka pani wahin se andar jata hai aur pehle picture mein lines aati hain, phir camera band ho jata hai.

Hal simple hai: har outdoor joint waterproof junction box mein ho, self-amalgamating tape se seal ho, aur cable ka 'drip loop' banaya jaye taake pani cable ke sath box tak na chale balke neeche gir jaye.

2. Load shedding ka asli nuqsan surge hai

• Bijli aane ke waqt ka voltage spike DVR ki power supply sab se pehle jalata hai
• Ek 12V SMPS ya adapter ka jalna aksar 3–4 cameras ek saath band kar deta hai
• Surge protector ya achha stabilizer 2–3 hazar ka hota hai aur 20 hazar ka nuqsan bachata hai
• UPS backup se recording gap bhi khatam ho jata hai — chori aksar bijli jane ke waqt hoti hai

3. Hard disk barish ke mausam mein sab se hassas hissa

Namee aur baar baar power cut hard disk ke liye zeher hain. Surveillance-grade disk (WD Purple ya Skyhawk) isi liye zaroori hai — desktop disk 24/7 recording par 1 saal mein jawab de deti hai.

Mahine mein ek baar mobile app kholein aur 10 din purani recording chala kar dekhein. Agar purani footage nahi chal rahi to disk ya recording schedule mein masla hai — barish ke mausam se pehle isay theek karwa lein.

4. Monsoon se pehle 10 minute ka checklist

• Har outdoor camera ka junction box khol kar dekh lein — pani ya zang to nahi
• Camera ka lens aur sun-shade saaf karein (dhool + barish = dhundli picture)
• DVR ki jagah ka pani se koi rasta na ho, deewar par seelan to nahi
• Power supply ke tamam connectors tight aur taped hon
• Purani recording playback test karein
• Mobile app par notification on rakhein taake camera offline ho to foran pata chale

5. Barish ke baad camera band ho jaye to kya karein

Sab se pehle power off karein — geela system chalate rehna short circuit ka khatra barhata hai. Phir junction box khol kar cable joint dekhein; aksar wahin masla milta hai aur 10 minute mein theek ho jata hai.

Agar picture aa rahi hai lekin dhundli ya dhundhli safed hai to camera ke andar namee ja chuki hai — us camera ko service ki zaroorat hai. Hamari team Karachi mein on-site aise cases roz handle karti hai, aur warranty period mein yeh visit free hoti hai.
