CCTV Installation Guide: Best Practices | Queen

Good installation is as important as the camera itself. Here is what professional CCTV installation covers.

Planning coverage

Cameras are positioned to cover entrances and blind spots with the right angles and heights, avoiding backlight and obstructions.

• Cover entrances and key areas
• Avoid blind spots and glare
• Right height and angle

Storage and remote access

A proper recorder (DVR/NVR) with enough storage, plus secure remote viewing on your phone, complete the system.

• Adequate recording storage
• Secure mobile remote viewing
• Backup power for reliability

Installation: where the result is decided

Most disappointing CCTV cameras systems are not faulty hardware — they are poor installation. The decisions taken during installation matter more than any specification: correct positioning matched to each point's purpose, proper cable of the right type and gauge, and a clean documented layout that makes future faults quick to fix.

What matters for this system specifically

Aim each camera at a written purpose before mounting — a gate, a face, a plate — because "general coverage" gives a picture of everything and useful detail of nothing. Avoid pointing a camera into a facing window: backlight turns anyone entering into a black silhouette. And ask for a night-time check at 10pm, because a camera aimed perfectly at noon can be useless when most incidents happen.

Ask what the handover includes: a layout drawing, credentials, and a maintenance contract with a defined response time. A system handed over without these becomes hostage to one technician.

The main types, and where each fits

Choosing CCTV cameras starts with knowing the types rather than the brands — each was designed for a different situation, and matching the type to the situation matters more than the price:

• By connection: analogue HD over coax (cheaper, reuses old cabling) vs IP over network with PoE (scales, higher resolution).
• By placement: indoor vs weatherproof outdoor (IP66+).
• By night vision: infrared (black and white) vs full-colour night cameras.
• By movement: fixed vs PTZ that pans and zooms over a wide area.

Below the type, the details decide the result: component quality, correct positioning, and adequate supporting infrastructure. A mid-range choice installed correctly beats a premium one installed poorly.

Before you decide

Ask for a survey before a price — a number given over the phone is a guess that changes on site. For this system in particular, ask specifically about storage — how many days of retention this system actually gives, in writing — and for a night-time site check before you accept it. And ask what happens the day something fails: who responds, how fast, and whether the handover left you the documentation to let anyone service the system.
