CCTV connectivity for remote sites

The short answer

Cameras are cheap and reliable. The link carrying their footage usually is not. Four things break remote CCTV, and in this order: not enough upload speed, a shared or contended connection, no power through an outage, and a link that was never surveyed for line of sight. Replacing the cameras fixes none of them.

If your cameras record fine locally but you cannot view them remotely, the cameras are working. The connection is the fault.

Camera problem or link problem? A test you can run today

Before anyone quotes you for new hardware, run these four checks. They take about twenty minutes and they will tell you which half of the system is failing.

1. Play back the recording locally

Go to the NVR or recorder on site and play back the footage from the period when the camera went offline. If the footage is there and it is clean, the camera never stopped. Only the remote viewing stopped — which is a link fault, not a camera fault.

2. Check your upload speed, not your download

Cameras push video out. Almost every consumer and small-business line in South Africa is asymmetric — big download, small upload. A 50/5 connection advertises 50 Mbps but only gives you 5 Mbps for the cameras. Test the upload figure specifically and compare it against the table below.

3. Watch it fail at a specific time of day

If remote viewing dies every evening between 18:00 and 22:00, that is contention — you are sharing a tower or a line with everyone else in the area. Nothing on your site is broken. You are simply being outcompeted for capacity at peak.

4. Check what happens in an outage

If the cameras have a UPS but the router, the switch and the mast radio do not, the whole system goes dark the moment the power does — with the cameras still running, recording nothing anyone can see.

How much upload CCTV actually needs

These are working ranges for H.265 cameras at moderate frame rates. Actual figures move with codec, frame rate, bitrate settings and how much movement is in the scene — a fixed camera on a quiet gate uses far less than one watching a treeline in wind.

Two things people get wrong here. First, they size against the download figure and wonder why it fails. Second, they size against the total and forget that the site also runs a lodge, an office or a weighbridge on the same link.

There is a way to cut the requirement sharply: record everything locally to an NVR on site, and only stream out on motion events or when someone actually opens the app. That turns a continuous 32 Mbps demand into occasional bursts. It is the single cheapest fix available to most sites, and it costs nothing but configuration.

The four ways to connect a remote camera site

Honest trade-offs, including where each one is the wrong answer.

LTE / 5G router with a SIM

Right when: the site has usable cellular signal, camera count is low, and you can live with variable performance.
Wrong when: signal is marginal, or you need continuous streaming. Upload on a contended cell is the first thing to collapse at peak, and data costs climb fast once cameras stream continuously. Many complaints about cameras dropping turn out to be a SIM router at the edge of coverage.

Satellite

Right when: there is genuinely no terrestrial option and no line of sight to anything.
Wrong when: you need consistent low latency, or you are in heavy rain country. Latency and weather sensitivity vary a lot by system. It is a real answer for genuinely isolated sites and an expensive one everywhere else.

Point-to-point wireless link

Right when: there is line of sight — or a path that can be made to have line of sight with a mast or a relay on a koppie — to a point that already has capacity. Gives you dedicated, symmetrical, uncontended bandwidth, which is exactly what cameras want.
Wrong when: terrain genuinely blocks every path and no relay site is available. This is what a survey establishes before anyone spends money.

Fibre

Right when: it already reaches the site or the trench is short.
Wrong when: you are quoted a build across kilometres of someone else's land. The cost and the wayleave timeline are usually the reason people are reading this page in the first place.

The three failures that actually kill remote CCTV

Asymmetric upload

Covered above, and it is the most common single cause. If you take one thing from this guide: size the link on upload.

Contention

A shared connection gives you whatever is left after everyone else. Cameras need capacity at the exact hours when contention is worst — evenings and overnight. A dedicated link does not have this problem, which is most of why it costs more.

Power

South African sites lose power routinely. A camera system is only up if every element in the chain is up: cameras, switch, recorder, router, and the radio on the mast. Backing up the cameras alone is the most common design mistake we see, and it produces the worst outcome — a system that records nothing viewable and looks fine on inspection.

What an engineered link actually involves

The difference between a link that works for five years and one that works until the first bad weather is almost entirely in the work done before installation.

Survey

Establish where the site is, where the nearest viable capacity is, and whether a path exists between them. This is measured on site and against terrain, not estimated from a map.

Line of sight and clearance

A wireless path needs more than a visible straight line. It needs clearance around that line — the Fresnel zone — and trees grow into it, seasonally and over years. A path that clears in winter and fails in summer is usually a clearance problem that was never calculated.

Mast height and structure

Most marginal paths become good paths with height. Getting the radio ten metres higher is often cheaper than any other fix, and it is the first thing a survey checks.

Equipment and spectrum

Unlicensed bands are cheaper and fine on quiet paths. Busy areas need licensed spectrum or carefully planned channels, or you inherit everyone else's interference.

Support after handover

Infrastructure that nobody monitors becomes infrastructure that fails silently. The point of an engineered link is that someone knows it is degrading before you do.

CTTX carries out the survey, designs the network, builds it with our own teams and supports it afterwards. How you pay for it is covered in the next section — and it is not a monthly line rental.

How you buy it: you own the network

This is where CTTX works differently to an internet provider, and it is the part most people do not expect.

We design the network, we build it, and you buy it outright. The masts, the radios, the fibre, the power, the enclosures — it is your asset on your books the day we hand it over. We are not renting you a line and keeping the infrastructure.

Why ownership is the better deal on a remote site

• You are not locked to anyone. You own the infrastructure, so you decide whose capacity rides across it, and you can change that decision later without rebuilding anything.
• It is a capital asset, not a permanent monthly cost. It sits on the balance sheet like any other plant on the operation, and it can be financed the same way as any other capital equipment.
• It stops costing you. A rented line costs the same in year seven as in year one, and you own nothing at the end of it. A network you bought is paid for.
• It carries more than the cameras. A link engineered for eight cameras also carries the office, the workshop, the scale, the pivots and the guest Wi-Fi later, with no second infrastructure spend.

What you actually commit to, in order

• Site survey — R3,500 excluding VAT, credited back against the build if you proceed. This establishes whether a viable path exists and what the network would cost. You are not committed to anything beyond this point.
• Design and quotation. You see the design and the build cost before you decide.
• Build and handover. Our own teams build it. It becomes your asset.
• Support. Ongoing monitoring and maintenance of infrastructure you own — separate from, and much smaller than, renting a line forever.

Whatever carrier capacity you choose to run over the network is a separate service decision, and yours to make. The infrastructure underneath it is yours either way.

For security companies and installers

If you install and monitor CCTV, the link is usually the part of the job you inherit and cannot control — and it is the part your client blames you for when remote viewing drops. You install the cameras; someone else's failing connection defines your service quality.

CTTX designs and builds the connectivity layer underneath security installations, and the network is bought outright — which means it can be bought by you or by your client, whichever suits the deal. Buy it into your own book and you own an asset on that site and the relationship that goes with it. Have the client buy it and you have solved their problem without carrying the capital yourself. Either way the link stops being the part of the job you get blamed for and cannot fix.

We design it, we build it, we support it. You keep the client. If you run sites where the cameras are fine and the connection is not, we should talk.

Common questions

Why do my CCTV cameras keep going offline?

In most cases the cameras are not offline at all — the connection carrying them is. Play back the footage locally on the recorder. If it is there, the cameras worked and the link failed. The usual causes are insufficient upload speed, a contended shared connection, or the router and mast radio losing power while the cameras stay on backup.

How much internet speed do I need for CCTV?

Size on upload, not download. Budget roughly 1–2 Mbps of upload per 1080p camera, 2–4 Mbps per 4MP camera and 6–10 Mbps per 4K camera for continuous streaming, and add whatever else the site runs. Recording locally and streaming only on motion cuts that requirement dramatically.

Can I run CCTV on an LTE SIM router?

Yes, where cellular signal is genuinely good and camera count is low. It becomes unreliable at the edge of coverage or at peak times, because upload capacity is the first thing to degrade on a contended cell, and continuous streaming makes data costs climb quickly.

Can I get CCTV connectivity where there is no cellphone signal?

Usually yes. Where there is no usable cellular coverage, the answer is normally a point-to-point wireless link from the site to a point that does have capacity, sometimes via a relay on high ground. Whether a path exists is what a site survey establishes. A site with no signal is not the same thing as a site with no options.

Do I rent the network or own it?

You own it. CTTX designs and builds the network and you buy it outright, so the infrastructure is your asset rather than a line you rent indefinitely. Because it is a capital asset it can be financed like any other equipment on the operation. Carrier capacity running over the network is a separate decision that stays yours.

What does a site survey cost?

R3,500 excluding VAT, credited back against the build if you proceed.

Do you work outside the Eastern Cape?

Yes. CTTX operates from Gqeberha and Cape Town across all nine provinces, with most work in the Eastern Cape, Western Cape, Limpopo and Mpumalanga.
