How to plan a CCTV system for a small business

Most camera systems that disappoint their owners fail at planning, not at hardware. Cameras end up pointing at the wrong place, cables run longer than expected and nobody knows what was installed. A short plan before the first drill hole avoids all three.

1. Start with what you need to see

Write down the goal of each camera before choosing a model. Reading a license plate at a gate needs a different camera and angle than watching a hallway. One goal per camera keeps the design honest.

• Identify people at entrances and exits
• Read license plates at gates or drive lanes
• Watch cash handling or storage areas
• General awareness of a yard, lot or open room

2. Mark camera positions on a floor plan

Place every camera on a plan or a site photo, with its field of view. Check for glare from windows, tree growth, lighting at night and anything that blocks the view. This is also the moment to decide mounting height and whether the spot has power and network nearby.

3. Work out cabling and power

Most modern cameras use a single network cable that carries power (PoE). Measure each run, note where it passes through walls or ceilings and keep every run within the cable limit for the standard you use. A cable schedule with one line per camera saves hours during installation.

4. Size recording and storage

Storage depends on the number of cameras, resolution, frame rate and how many days you must keep footage. Decide the retention period first, then size the recorder or storage to match, and leave room to add cameras later.

5. Document what was installed

Keep a drawing, an equipment list with models and quantities, and a list of cable runs and labels. When something fails in two years, this is what lets a technician fix it in minutes instead of hours. It also makes quotes between installers comparable.

If you want a tool to do steps 2 to 5 in one place, NextQ Designer lets you place devices on a plan, draw cable routes and get a bill of materials from the same drawing.
