🎯 What Are CCTV Blind Spots?
A blind spot is any area that your camera does not cover, meaning suspicious activity in that zone won’t be recorded. It could be a corner, shadowed area, or just poor angle coverage.
❓ Where Are the Common Blind Spots in SG Homes?
Here are some areas that are often missed:
-
🔒 Main Door Corners – Poor angle or height
-
📦 Gate/Mailbox – Parcel thefts go unseen
-
🚪 Service Yard/Back Door – Entry point for break-ins
-
🏢 HDB Corridors – Outside camera field or blocked by grills
-
🚗 Driveway or Porch – For landed homes
-
📚 Study or Utility Room – Often overlooked but stores valuables
❓ How Can You Eliminate CCTV Blind Spots?
✅ 1. Plan Using a Floorplan
-
Mark key entry points and long corridors
-
Highlight hidden corners or dead zones
-
Position cameras with overlapping coverage
✅ 2. Use Wide-Angle or Varifocal Lenses
-
Standard lens: 70–90°
-
Wide-angle lens: 110–180°
-
Varifocal: Adjust zoom for specific coverage
✅ 3. Combine Dome + Bullet Cameras
-
Dome cams: Indoor use, discreet, wide coverage
-
Bullet cams: Outdoor, targeted view (e.g. gates)
✅ 4. Mount at the Right Height
-
Ideal: 2.4–2.8 metres
-
Avoid overhead shots that miss faces
✅ 5. Avoid Obstructions
-
Don’t point cameras through grilles
-
Avoid blinds/curtains blocking views
-
Test both day and night for IR light issues
✅ 6. Use PTZ or AI Smart Cameras
-
PTZ: Can rotate and zoom automatically
-
AI models: Motion tracking, zone alerts
-
Set app zones to ignore plants/pets
✅ 7. Do a Post-Install Walk-Test
-
Stand at all entries/corners
-
Check for full body + face coverage on live view
📊 What Camera Setup Works Best by Property Type?
| Property Type | Recommended Setup |
|---|---|
| HDB Flat | Dome at main door, bullet outside facing corridor/gate |
| Condo Unit | Wide-angle in foyer, motion cam at balcony/service yard |
| Landed House | Bullet at gates/fence, dome at door/driveway, PTZ at backyard |
🧠 What Extra Tips Help Prevent Gaps?
-
📌 Label each feed in your app (e.g. “Yard” / “Porch”)
-
☁️ Use cloud backup for footage
-
🎯 Angle cameras slightly downward
🧪 Singapore Case Study
Real Example: A Bukit Batok homeowner installed a camera pointed at their front door but didn’t cover the corridor. A thief walked just out of frame and stole a parcel. They later re-angled the camera 30° outward and added a dome cam inside. Problem solved.
