1. Poor Camera Placement

One of the most common mistakes is positioning cameras in the wrong locations. Cameras that are too high, too low, or pointed in the wrong direction often miss important activity.

Common Placement Errors

• Installing cameras too high, reducing facial clarity

• Mounting them too low where they are easy to tamper with

• Pointing cameras toward bright light sources

• Ignoring hidden or blind spots

How to Avoid This

Identify vulnerable areas such as entry doors, backyards, garage entrances, and side passages. Cameras should be placed 8 to 10 feet above ground to capture a clear view while staying out of reach.

---

2. Ignoring Camera Field of View

Many homeowners install cameras without checking their field of view, leading to incomplete coverage. A wide-angle lens captures more space but may reduce detail, while a narrow-angle lens captures more detail but less area.

How to Avoid This

Before installation, test the camera’s field of view using the mobile app. Walk around the area and check coverage gaps. Adjust angles until you see all critical zones.

3. Installing Cameras Facing Direct Sunlight

Pointing cameras directly at sunlight creates glare, shadows, and overexposure, making footage unusable. Bright light sources like streetlamps also reduce clarity at night.

How to Avoid This

Install cameras under shades or eaves, angled slightly downward. Use WDR (Wide Dynamic Range) cameras for areas with strong light contrast.

---

4. Poor Cable Management and Wiring

Loose wires, exposed cables, and improper connectors are common issues, especially in DIY setups. Poor wiring results in unstable video signals, flickering footage, or complete power loss.

How to Avoid This

• Use high-quality cables designed for CCTV

• Keep power and video cables separate

• Avoid sharp bends in cables

• Secure wires using clips and conduits

For outdoor setups, ensure cables are waterproof and concealed.

5. Not Securing the DVR/NVR Properly

The recorder stores all surveillance footage. If it is easily accessible, intruders can disable or steal it to destroy evidence.

How to Avoid This

Keep your DVR or NVR in a locked, hidden location. Choose a model that supports cloud backup or remote storage for extra safety.

---

6. Using Low-Resolution Cameras for Large Areas

Some homeowners choose low-resolution cameras to save money, which often results in blurry or pixelated footage, especially when zooming.

How to Avoid This

Use at least 1080p cameras for clear image quality. For wider areas such as driveways and backyards, consider 4MP or 5MP cameras.

---

7. Not Setting Up Motion Detection Properly

Incorrect motion detection leads to too many false alerts or, worse, missed activity. Many homeowners leave default settings unchanged.

How to Avoid This

• Adjust sensitivity levels

• Enable motion zones

• Schedule alert times

• Disable detection for irrelevant areas such as trees or traffic

Proper calibration reduces unnecessary notifications and improves system accuracy.

---

8. Ignoring Night Vision Configuration

Even good cameras fail at night if IR (infrared) settings are wrong. Reflections, glare, or obstructions can interfere with night vision.

How to Avoid This

• Clean the camera lens regularly

• Avoid installing cameras behind glass

• Ensure no objects block IR LEDs

• Choose cameras with IR-cut filters for better clarity

---

9. No Backup Power During Outages

Many homeowners forget that CCTV cameras need backup power. Without it, your entire system goes offline during a power cut, leaving your property unprotected.

How to Avoid This

Use a UPS or inverter to keep the DVR, NVR, Wi-Fi router, and cameras running during outages.

---

10. Not Protecting Cameras From Weather

Rain, heat, moisture, and dust can damage CCTV cameras if not properly protected. Even outdoor cameras can experience faults when exposed to severe weather.

How to Avoid This

Install cameras with IP66 or IP67 weatherproof ratings. Use protective housings to shield cameras from direct sunlight and heavy rainfall.

---

11. Neglecting CCTV Maintenance

A well-installed system can still fail if not maintained. Dusty lenses, outdated firmware, and loose connections can compromise footage quality.

Maintenance Checklist

• Clean lenses monthly

• Check cable connections

• Update DVR/NVR firmware

• Review storage health

• Test night vision regularly

---

12. Not Securing the CCTV Network

Modern CCTV systems often use Wi-Fi or cloud connectivity. If not secured properly, they become vulnerable to hacking, unauthorized access, or surveillance breaches.

How to Avoid This

• Use strong passwords

• Update firmware regularly

• Disable default login credentials

• Enable encryption for data transmission

• Use a separate network for cameras if possible

---

13. Installing the Wrong Camera Type

Different areas need different camera types. Dome cameras, bullet cameras, PTZ cameras, and IP cameras each serve unique purposes.

How to Avoid This

Select the right camera based on location:

• Dome: indoor, discreet monitoring

• Bullet: outdoor long-range coverage

• PTZ: large open areas

• IP: high-resolution remote monitoring

---

14. Not Considering Storage Capacity

Many homeowners install cameras but underestimate how much storage they need. Low storage means deleted clips, overwritten footage, or gaps in recording.

How to Avoid This

Use an HDD designed for surveillance (not regular desktop drives). Choose storage based on your recording duration, resolution, and number of cameras.

---

15. Setting Cameras Too Close to Each Other

Overlapping coverage from cameras placed too close results in wasted angles and unnecessary redundancy, while other areas remain uncovered.

How to Avoid This

Plan coverage zones before installation. Ensure each camera covers a unique area while slightly overlapping for security continuity.
