CCTV surveillance system me sabse high-resolution 4K camera lagwa lena bhi bekar ho jata hai agar camera galat angle par mount kiya gaya ho, lens par direct dhoop pad rahi ho, ya camera itna uncha laga diya jaye jahan se sirf logon ke sir (heads) dikhein lekin face identify na ho sake.
Professional security planning ka basic rule hota hai: "Har camera ka ek specific objective hona chahiye — Detection, Recognition ya Identification."
Is practical installation guide me hum Rajbala IT ke certified surveillance engineers ke standard blueprint ko explain kar rahe hain jisse aap apne home, retail store, warehouse ya commercial complex me maximum coverage achieve kar sakein bina unnecessary extra cameras ke kharche ke.
1. Golden Height Rule: Camera Kitni Unchai Par Lagayein?
Height selection surveillance efficiency ka sabse critical factor hai:
- Optimal Height: 8.5 se 10 Feet (2.5 to 3 Meters)
Is height par camera normal human reach se bahar rehta hai (tampering ya tod-fod se safe), aur angle aesa banta hai jisse entry karne wale insaan ka face direct eye-level identification frame me capture hota hai.
- Common Mistake: 14–16 Feet Par Camera Lagana
Log aksar first-floor balcony ke bottom par camera mount kar dete hain. Itni unchai se camera broad overview to deta hai, lekin cap ya helmet pehne shaks ka face kabhi identify nahi hota — sirf top-of-head capture hota hai.
2. Strategic Camera Placement Checklist
1. Main Entrance & Gate:
Hamesha camera ko gate ke samne facing direction me lagayein taaki entry aur exit karne wale har vehicle ka number plate aur pedestrian ka facial profile capture ho sake.
2. Cash Counter & Billing Desk:
Shop ya showroom me billing counter par 2.8mm wide-angle dome camera seedha cash drawer aur customer exchange area ke upar mount karein.
3. Corridors & Hallways:
Lambi corridors me 3.6mm ya 6mm lens camera lagayein jo narrow focal length ke saath door tak clear coverage de sake.
4. Perimeter Walls & Blind Spots:
Boundary walls par do cameras ko aamne-saamne cross-angle (Criss-Cross Pattern) me lagayein jahan ek camera doosre camera ke dead spot ko cover kare.
5. Parking & Loading Bays:
Vehicles ki overall movement aur loading-unloading activities cover karne ke liye outdoor weatherproof IP67 bullet cameras ka use karein.
3. Lens Focal Length Ka Sahi Chunav (2.8mm vs 3.6mm vs 6mm)
Camera body ke andar lens size decide karta hai ki coverage kitni wide hogi:
- 2.8mm Lens (Wide Angle ~ 100° View):
Chote rooms, office cabins, lift, aur shops ke liye best hai jahan wide area ek hi camera me cover karna ho.
- 3.6mm Lens (Standard ~ 80° View):
Main gates, driveway aur normal home security ke liye balanced choice (coverage + facial clarity).
- 6mm / 8mm Lens (Narrow Telephoto ~ 50° View):
Lambi boundary wall, factory driveways aur entry gate par number plate reading ke liye.
4. Sunlight & Direct Backlight Glare Se Bachne Ka Tarika
Agar camera east ya west facing wall par aese laga ho jahan subah ya sham ka suraj seedha lens par chamke, to 'Direct Glare' ki wajah se poori image black silhouette ban jati hai.
Fix:
- Camera ko thoda angled mount karein taaki suraj direct frame me na aaye.
- Hamesha True WDR (Wide Dynamic Range 120dB) enabled cameras choose karein jo bright background aur dark shadow dono ko balance karke clear face reveal karte hain.
5. Weatherproofing & Cable Conduit Planning
Outdoor cameras ke liye:
- IP66 ya IP67 weather-rated metallic body bullet cameras choose karein jo barish, garmi aur dhool jhel sakein.
- Sabhi wire connections (BNC / RJ45 / DC Jack) ko waterproof PVC camera junction box ke andar seal karein. Wires ko khule me latakta na chhodein.
- High-grade heavy-gauge PVC conduit pipe me wire lay karein taaki rodents (chuhe) cable na kaat sakein.
