Top 5 Security Camera Installation Mistakes (and How to Avoid Them)

A security camera system is only as good as its installation. We've walked into countless properties where the cameras were technically fine — but the installation was so poor that the entire system was essentially useless.
Here are the five most common security camera installation mistakes we see, and how to avoid them.
Mistake 1: Poor Camera Placement
This is the number one issue. Cameras pointed at walls, mounted too high to capture faces, or angled so that the sun washes out the image every afternoon.
How to avoid it:
- Mount cameras at 2.5 to 3.5 metres height — high enough to prevent tampering, low enough to capture faces
- Point cameras away from direct sunlight to avoid glare and backlight issues
- Ensure overlapping coverage — no blind spots between cameras
- Always do a test view before finalising the mount position
A professional installer will do a site survey and plan camera positions on a layout before drilling a single hole.
Mistake 2: Exposed and Messy Cabling
We see this all the time — cables dangling from walls, taped to corners, running across floors. Not only does it look terrible, but exposed cables are vulnerable to:
- Weather damage (rain, UV)
- Rodent damage
- Vandalism or tampering
- Accidental disconnection
How to avoid it:
- Use PVC conduits for all cable runs
- Run cables inside walls or along ceilings wherever possible
- Use cable trays in server rooms and utility areas
- Never use electrical tape as a permanent cable management solution
At EyeNox, clean cabling is non-negotiable. Every installation gets concealed conduits and professional cable management.
Mistake 3: Inadequate Storage Planning
Installing 16 cameras recording at 4K resolution on a 1TB hard drive? That gives you roughly 3-4 days of footage before it starts overwriting. For many businesses, that's nowhere near enough.
How to avoid it:
- Calculate your storage needs based on: number of cameras × resolution × recording hours × desired retention period
- Use surveillance-grade hard drives (not regular desktop drives)
- For large setups, consider RAID configurations for redundancy
- We typically recommend 15-30 days minimum retention for businesses
Mistake 4: Ignoring Network Infrastructure
IP cameras rely on your network. If the network is unreliable, your cameras will drop frames, lose connection, or fail to record. We've seen setups where cameras were connected to the same router as 50 office computers — leading to constant buffering and dropouts.
How to avoid it:
- Use a dedicated network (separate VLAN) for security cameras
- Install a PoE switch rated for your camera count — don't overload
- Use Cat6 cabling (not Cat5) for future-proofing and reliability
- Ensure your NVR has a wired connection to the switch — never Wi-Fi
Mistake 5: No Backup Power
A power outage shouldn't mean your security goes down. Yet many installations have no backup power for cameras or NVR.
How to avoid it:
- Install a UPS (Uninterruptible Power Supply) for the NVR and PoE switch
- For critical areas, consider battery-backed cameras or solar setups
- Ensure the UPS is rated for at least 2-4 hours of runtime for your setup
The Bottom Line
Most of these mistakes happen because people try to save money with DIY installations or hire unqualified technicians. A professional security camera installation costs a bit more upfront but saves you from:
- Repeated service calls
- Unusable footage when you actually need it
- System failures at the worst possible time
At EyeNox, we handle CCTV installation with a focus on getting it right the first time. Every installation comes with a 12-month workmanship warranty.
