A commercial camera system is more than cameras. The work is choosing the right lens and housing for each view, sizing the network and storage for the retention you need, and installing it so the system still works in two years. We design, install and support the whole chain.
Most disappointing camera systems fail for reasons that have nothing to do with the camera brand. A lens is too wide for the distance, a camera is aimed at a light source, the recorder cannot hold enough days, or the network was never sized for video. The result records something, just not the thing you needed to see.
We start with what you need to see and what you need to prove. From there we specify the cameras, the recorder, the storage and the network together, and we test the views before the installation is signed off.

What a commercial camera system includes
A working system is a chain, and every link has to be sized for the job. We specify and install the whole chain rather than dropping cameras onto an existing network and hoping.
- Cameras chosen per view: fixed dome, bullet, turret or PTZ, with the lens and resolution that match the distance and the detail required.
- A recorder or video management system sized for the number of cameras, the resolution and the retention period.
- Storage that survives a disk failure where the site needs it, and a retention plan you can explain to an insurer.
- PoE switching, cabling and bandwidth planned for video rather than for office traffic.
- Remote viewing and user accounts that match how the site is actually managed.
Matching the camera to the view
The same camera is rarely right for an entrance, a loading dock and a long parking aisle. A wide lens at a doorway identifies a person; the same lens at 30 meters identifies a shape. A PTZ covers a wide area but cannot watch everywhere at once.
We test candidate views with a temporary camera or a site walk before specifying the final positions, so the coverage you approve is the coverage you get.
- Dome cameras where discretion and vandal resistance matter.
- Bullet cameras for long, narrow views such as fences and driveways.
- PTZ cameras where operators need to follow activity across a large area.
- Low-light and wide-dynamic-range models where the site has bright sun, headlights or deep shade.
- Housings and mounts that suit the surface, the weather and the maintenance access.
The network and storage decide the result
Video is the heaviest traffic on most small networks. If the switches, cabling or recorder cannot carry it, cameras drop frames, recordings gap, and remote viewing stalls. We plan the network as part of the camera system, not as an afterthought.
Retention is a business decision as much as a technical one. We ask how many days you need, whether the recorder needs redundancy, and whether any footage has to be exported for insurers, HR or law enforcement.
- PoE and PoE+ switching sized for the camera count and the cable runs.
- Recorder throughput checked against resolution and frame rate, not just camera count.
- Storage sized for the retention you ask for, with RAID where a single disk failure is unacceptable.
- A separate camera VLAN or network where the site needs it.
Installation details that prevent callbacks
A neat installation is not cosmetic. Proper mounts, sealed penetrations, drip loops and service loops decide whether a camera survives its first winter and whether the next technician can service it without cutting the cable.
We commission every view, confirm the recording and retention, and walk the system with you before handover. The handover includes the recorder location, the account structure and what to do when something stops recording.
- Cable routes protected and labelled, with service loops at each camera.
- Mounting heights and angles that avoid glare, foliage and tampering.
- Recorder and switch placement with ventilation and physical access considered.
- A commissioning check of every camera, every recording and the retention period.
Using analytics without alert fatigue
AI and video analytics are useful when they reduce the number of alerts a person has to review. They are counterproductive when every shadow, animal or cloud triggers a notification and the team stops looking.
We set up analytics around the events that matter on your site, then tune them after a period of real activity. On parking and industrial sites that often means vehicle detection and line crossing rather than generic motion.
- Human and vehicle filtering instead of raw motion detection.
- Line crossing, intrusion and loitering rules around real boundaries.
- Alert routing to the people who can act on it, not to everyone.
- A review period after handover to tune out false triggers.
Working with an existing system
Not every project starts from zero. We repair, extend and take over camera systems that were installed by someone else, including systems built around Hikvision, Dahua, Axis, Avigilon, Digital Watchdog, Uniview, Pelco, Bosch and Speco equipment.
Where the existing cameras are sound, we keep them and replace the weak link: the recorder, the storage, the network or the viewing software. Where they are not, we explain what can be reused and what cannot before quoting.

What we need to quote a camera system
A useful quote needs more than a camera count. Tell us the site, the areas you need covered, what you need to identify or prove, how long footage must be kept, and whether there is existing equipment you want to keep.
For commercial and industrial sites we usually start with a site walk. For a smaller system, photographs and a floor plan can be enough to scope the first conversation.
- Address and a site contact who can walk the property.
- A simple plan or sketch marking the areas of concern.
- Whether the priority is deterrence, evidence, operations or all three.
- Retention period and who needs access to footage.
- Any existing cameras, recorders or network equipment.
Frequently asked questions
How many cameras does a commercial site need?
It depends on the views, not the square footage. We map the entrances, the high-value areas and the perimeter first, then choose the lens for each view. A small site with two entrances can need fewer cameras than a single open yard.
How long should we keep camera footage?
That is a business decision driven by your insurer, HR and legal needs, and by how quickly an incident is usually discovered. We size the storage to the retention you choose and tell you what changing it would cost.
Can you work with our existing cameras?
Often yes. Many systems can be extended or moved onto a new recorder if the cameras support the required protocol. We inspect the existing equipment before promising reuse.
Do you install cameras outside normal business hours?
Installation timing is planned around the site. Retail, hospitality and industrial sites often need work staged outside trading or production hours, and that is agreed before the project starts.
