Walk into any security shop and you will hear the same pitch: more megapixels, more cameras, more everything. But after installing CCTV systems across factories, offices, hospitals and housing societies since 2016, we can tell you the truth is simpler. The right CCTV system is not the most expensive one. It is the one designed around your site.
This guide walks you through the decisions that actually matter when you are planning CCTV installation for a business, in the same order we work through them during a site survey.
Before thinking about brands or budgets, walk your premises and list what genuinely needs watching: entry and exit gates, cash counters, storage areas, machine floors, parking, and corridors connecting them. This list, not a round number like 8 or 16, should decide your camera count.
A common mistake we see is buying cameras in even numbers to fill a DVR, then discovering the one blind spot that mattered was never covered. A proper CCTV site survey maps every critical zone first and places cameras to overlap slightly, so there is no dead angle between them.
Most sites need a mix. A typical factory setup we install might use bullets on the perimeter, domes in production and office areas, and one PTZ covering the yard.
HD analog systems are economical and perfectly adequate for smaller premises: shops, clinics, small offices. They deliver clear footage at a lower cost per camera.
IP camera systems cost more but bring higher resolution, better scalability and access to AI features like intrusion detection and face recognition. If you are wiring a new premises or planning to grow, IP over structured cabling is usually the smarter long-term choice, because the network you lay today carries whatever camera you buy tomorrow.
Storage is where many installations quietly fail. Recording days depend on camera count, resolution, frame rate and disk size, and an undersized hard disk silently overwrites the footage you needed. As a working rule, decide your retention target first, 15, 30, 60 or 90 days, and let your installer size the NVR and disks to meet it.
Also ask about motion-based recording. Recording only when something moves can multiply your effective retention without adding disks.
Two identical camera kits can perform completely differently depending on who installs them. Neat, labelled cabling, correct mounting heights, proper power supplies and configured remote viewing are what separate a professional job from a weekend job. Insist on a walkthrough and training at handover, and ask what the AMC covers, because cameras that are never cleaned or checked degrade quietly.
A useful way to think about CCTV budgets: spend on glass and storage, save on decoration. Camera sensor and lens quality decide whether footage is usable evidence or a blur, and storage decides whether the footage still exists when you need it. Those two deserve the money.
Where can you reasonably save? You do not need 4K everywhere, 2MP and 4MP cameras remain excellent for general areas, with higher resolution reserved for faces at entries and number plates at gates. You also do not need a monitor wall if two people will ever watch it; mobile viewing covers most small businesses. And resist paying for AI analytics on every camera when only your perimeter and entries genuinely need them.
One place never to save: power. Cheap power supplies are the single most common cause of flickering, rebooting cameras we get called to fix. A proper PoE switch or quality SMPS costs little extra and removes an entire category of faults.
Can I view the cameras on my phone from anywhere? Yes, every system we install includes configured mobile viewing over the internet, with secure login.
What happens in a power cut? Cameras go down with the power unless you add a UPS to the recorder and switch, which we recommend at least for the recording side, so the system resumes cleanly and no disk corruption occurs.
Will cameras work at night? All cameras we specify include IR night vision; the honest caveat is that IR range varies by model, so gates and perimeters get cameras with the reach they actually need.
