Off-Grid Security Cameras in South Africa: Power, Data and Storage

In short

• On a property with no grid and weak broadband, record locally and use mobile data only to alert and to view. Streaming every camera to the cloud over LTE runs to hundreds of gigabytes a month, which no prepaid bundle covers.
• For two to four cameras near the house, PoE cameras on an NVR with one 4G router are the most resilient layout. Self-contained solar 4G cameras suit a remote gate or borehole, but each needs its own SIM and bundle.
• Four 4MP PoE cameras, a 4-channel NVR, a surveillance drive and a 4G router need about 1.7 kWh a day with headroom, going by their spec sheets. That calls for a small dedicated LiFePO4 bank and a few hundred watts of panel.

Which camera setup works on an off-grid property?

Two layouts work. One is PoE IP cameras cabled to a network video recorder (NVR), which records on site and reaches the internet through one 4G router. The other is a self-contained solar 4G camera with its own panel, battery, SIM and memory card. Most properties need the first, adding the second where cable cannot reach.

The NVR layout keeps the evidence on site, runs every camera from one battery bank and needs only one SIM. Its limit is cable length, so it suits a homestead, yard or gate near the house. Check the PoE budget as well. The Hikvision DS-7104NI-Q1/4P, a common 4-channel unit, supplies up to 36 W across its four PoE ports, according to its datasheet.

A solar 4G camera needs no trench, its whole appeal at a far gate or stock camp. But its microSD card leaves with it if it is stolen, it sleeps between events to save battery, and it relies on signal at that exact spot.

A 4G camera fed from 12 V rather than a battery is different. Hikvision’s DS-2CD1043G2-LIDUF/4G is rated at 9 W maximum on its datasheet. That is 216 Wh a day, so it needs a battery and panel like any IP camera. That sheet lists its LTE bands (B2/3/4/5/7/8/28/66); check any 4G camera’s bands against your local network before buying.

Placement beats type: as the guide to layering a smallholding perimeter argues, one camera on the approach and gate beats several along a boundary nobody reviews.

How much power do off-grid security cameras use?

By datasheet maxima, a 4MP PoE bullet camera with infrared and white light draws up to 9 W, a 4-channel NVR up to 10 W, its 2 TB surveillance drive 3.8 W, and a small 4G router 7.65 W. Add them, multiply by 24 hours and add headroom: that is what the battery and panel must supply daily.

The Hikvision DS-2CD1043G2-LIU(F) datasheet gives the camera’s PoE maximum as 9 W. It peaks at night with the lights on, so the table is a ceiling. The NVR datasheet gives its consumption as 10 W or less. The WD Purple datasheet gives the 2 TB WD22PURZ as 3.8 W at read/write. The TP-Link TL-MR100 uses a 9 V/0.85 A supply.

The table adds 20% headroom for conversion and cable losses. The NVR runs on 48 V DC, so a 12 V bank needs a small inverter or DC-DC converter between them. Check its no-load draw; it runs all day. The battery is sized for one sunless day at 80% depth of discharge, which is within the LiFePO4 range explained in the battery storage guide. The panel is sized for 4 peak-sun hours, a conservative example; replace that with your site’s worst-month figure.

Power and data budget: two and four cameras on an NVR

Line	2 cameras	4 cameras
Cameras (9 W max each)	2 × 9 = 18 W	4 × 9 = 36 W
NVR (≤10 W) + 2 TB drive (3.8 W)	13.8 W	13.8 W
4G router (9 V × 0.85 A)	7.65 W	7.65 W
Total continuous load	39.45 W	57.45 W
Daily energy (× 24 h)	946.8 Wh	1,378.8 Wh
With 20% headroom	1,136 Wh	1,655 Wh
Battery for one sunless day (÷ 0.8 DoD)	1,420 Wh = 111 Ah at 12.8 V → 2 × 100 Ah	2,069 Wh = 162 Ah at 12.8 V → 3 × 100 Ah (two give only 2,048 Wh usable)
Panel (÷ 4 peak-sun hours)	284 W → 2 × 160 W	414 W → 3 × 160 W
Charge controller (panel W ÷ 12.8 V)	25 A → 30 A MPPT	37.5 A → 50 A MPPT
Motion clips: 40 × 15 s a day at 2 Mbps = 150 MB/day per camera	2 × 4.5 = 9 GB/month	4 × 4.5 = 18 GB/month
Live view: 10 min a day at 512 kbps = 38.4 MB/day per camera	2 × 1.15 = 2.3 GB/month	4 × 1.15 = 4.6 GB/month
Monthly data, recording locally	11.3 GB	22.6 GB
Monthly data, continuous 2 Mbps upload (21.6 GB/day per camera)	1,296 GB	2,592 GB

Units are decimal, months 30 days. Bitrates are your choice: the camera accepts 32 kbps to 8 Mbps, and 2 Mbps main with 512 kbps sub-stream are reasonable for 4MP H.265.

The parts, as priced in September 2026, were as follows. At CCTV Direct, a Hikvision 4MP Smart Hybrid Light IP bullet cost R1,895. The same shop listed the Hikvision 4-channel Mini 4 PoE NVR (DS-7104NI-Q1/4P) at R2,199, or R3,599 with a 2 TB drive. Tech Guy SA had the TP-Link TL-MR100 at R930. At Sunstore, a Dyness 12.8 V 100 Ah LiFePO4 battery cost R3,107.88, a Cinco 160 W panel R1,216.88 and a Victron BlueSolar MPPT 100/30 R1,932.48, with the 100/50 at R2,536.38. That puts parts for the four-camera build at R27,619.66 and the two-camera build at R18,901.00, excluding cable, mounting, the 48 V supply, enclosure and labour.

How much mobile data do security cameras use in South Africa?

On the table’s settings, a camera that records locally and sends only motion clips and short live views uses about 5.65 GB a month. Streaming a 2 Mbps main stream to the cloud around the clock would use 648 GB. South African prepaid LTE pricing covers the first easily and rules out the second.

Vodacom’s prepaid plans page listed these 30-day Prepaid LTE bundles in September 2026:

• 10 GB Anytime plus 10 GB Night Owl: R149
• 20 GB plus 20 GB: R229
• 50 GB plus 50 GB: R349
• 100 GB plus 100 GB: R449

Two NVR cameras (11.3 GB) fit the R229 bundle, and four (22.6 GB) need the R349 one. The largest covers barely a sixth of one continuously streaming camera.

The same page listed out-of-bundle Prepaid LTE data at R0.29 per MB, or R290 per 1,000 MB, so set a hard cap. Vodacom’s Night Owl terms limit the Night Owl half of the bundle to between midnight and 05:00. That suits scheduled uploads of flagged clips, not live alerts.

The layout also changes the bill. Four solar 4G cameras need four SIMs, and at 5.65 GB each, each needs at least the R149 bundle. That is R596 a month, against R349 for one router serving four NVR cameras. Compare MTN and Telkom on their current pages too, and choose the network strongest at the camera.

Should footage be stored locally or in the cloud?

Store footage locally and keep only selected clips in the cloud. A local recorder holds weeks of continuous footage and uses no data. A cloud copy protects the clips that matter if the recorder is stolen or burnt, and it costs only the data needed to upload them.

Recording continuously at 2 Mbps uses 21.6 GB per camera per day. A 2 TB drive therefore holds roughly 46 days for two cameras and 23 days for four, a little less once formatted. A 256 GB microSD card in a single 4G camera holds under 12 days of continuous recording.

Hide the recorder in a locked, ventilated cabinet, run cable out of sight, and push motion clips to a phone as they happen. The monthly security running costs breakdown covers the subscription side of cloud storage.

What matters for night vision off the grid?

Three things matter at night: how far the camera sees, how little light it needs and how many watts its light uses. Infrared produces black-and-white images in total darkness. White light gives colour but uses more power and shows people where the camera is. A hybrid mode switches to white light only when it detects a person.

The DS-2CD1043G2-LIU(F) datasheet gives the camera’s light range as up to 30 m and says it records colour down to 0.005 lux. It also offers four programmable privacy masks. Treat 30 m as the limit for detecting movement, not for identifying people. Mount the camera where faces pass within a few metres of it.

Infrared draws insects, insects draw spiders, and a web across the lens triggers alerts all night. Lighting the approach, covered in solar security lighting that lasts, also lets cameras record in colour without their own lamps.

How do you keep cameras running through outages?

Run the cameras, recorder and router from their own solar-charged DC battery bank, so that load-shedding, a fault or an overcast day changes nothing. You cannot back up the mobile network, though. The recorder has to keep recording when the nearest mast goes quiet, and on a solar-charged bank it will.

A separate, always-on circuit for security is the principle behind the security pillar. Keep it off the household inverter, so a pump or kettle cannot trip it, and size it with the measure-first solar sizing method.

A mast runs on its own backup power, and a long outage can take it down. When it does, alerts stop but local recording carries on. The alarm system should have its own communicator and battery. A dual-SIM router can fall back to a second network, and a scheduled reboot recovers a frozen modem.

Does POPIA apply to cameras on a private property?

POPIA excludes processing “in the course of a purely personal or household activity” (section 6(1)(a)), so cameras watching only your own home generally fall outside it. Once a camera covers a public road or a neighbour’s land, or records the staff and visitors of a farm business, the use is no longer purely household.

That wording is in the Protection of Personal Information Act 4 of 2013. The Information Regulator’s draft code for gated accesses, gazetted on 30 April 2026, sets CCTV retention at 7–30 days with automatic overwriting. Only footage linked to an incident is kept longer. It targets estates, not farms, but is a sensible benchmark.

In practice: point cameras at your own land, mask neighbours’ windows and the road, sign the entrance, overwrite automatically, and tell any employees where the cameras are and why.

Key takeaways

• Record locally; spend mobile data only on alerts, live views and selected clips.
• Budget from the datasheets. Four PoE cameras with an NVR, drive and router need about 1,655 Wh a day with headroom.
• Size the battery for one sunless day at 80% depth of discharge, and the panel from your worst month.
• Four solar 4G cameras need four bundles, so their data costs more each month than one router serving four NVR cameras.
• No LTE bundle covers continuous cloud streaming.
• Hide the recorder, mask what is not yours, overwrite on a cycle.

Frequently asked questions

Can a security camera run on a solar panel alone?

No. It needs a battery, because night is when it works hardest. Self-contained solar 4G cameras have both built in. For example, CCTV Direct listed the Hikvision 4MP 24/7 Solar 4G PT at R2,899 in September 2026, with an 8 W panel and a 9,000 mAh battery. PoE cameras need a battery bank sized as in the table above.

Which network is best for a 4G security camera?

The strongest at the camera. Test each network with a phone at the mounting point and height, and check the camera supports that network’s LTE bands.

How much data does one security camera use a month?

On the settings used here, about 5.65 GB if it records locally and uploads clips and short live views. Streaming 2 Mbps continuously would use 648 GB. The bill depends on the bitrate, the clip length and how often motion triggers a recording.

Do I need Wi-Fi for security cameras on a farm?

No. An NVR records without internet, and a 4G router adds remote access. Wi-Fi weakens with distance, so it suits large properties poorly.

How long should I keep security camera footage?

The law sets no period for a purely household system. The Information Regulator’s draft gated-access code suggests 7–30 days, overwritten automatically, with incident footage exported separately: a sound default anywhere.
