Solar Ajax Hub BP
A solar-powered alarm
that never needs a mains supply.
Put an LTS Xpand solar module on a pole and an Ajax Hub BP behind it, and a property that has never had power gets a fully monitored alarm with photo verification — reaching detectors up to two kilometres out, and topping itself up every morning.
The sites nobody could alarm properly
A 200-hectare farm. A machinery compound down an unsealed road. A solar farm, a quarry, a set of grain silos, a construction site three months from its first permanent supply. All of them have assets worth six figures and no practical way to run power to a control panel.
Until recently the options were poor. A mains-powered hub in a shed meant trenching, a switchboard and an electrician — often costing more than the alarm. A standalone battery siren gave you noise and nothing else: no monitoring, no verification, no idea whether it was a thief or a kangaroo.
Hub BP Jeweller removes the constraint entirely. It is a full Ajax control panel — same app, same monitoring, same detectors — that simply never expects mains power. Put it behind an LTS Xpand solar module and the site stops having a power problem at all: the panel runs the alarm indefinitely and leaves capacity spare for comms and cameras.
Solar in. Alarm out. Nothing else needed.
Ajax supports powering Hub BP from external supplies including solar. An LTS Xpand LT-MSP-509X delivers regulated 12 V from a 100 W panel with a 50 Ah lithium battery on its back — which turns a battery-limited alarm into permanent off-grid infrastructure.
No return visits
A zinc-air battery is excellent until the day it runs out and someone drives two hours to change it. Solar removes the maintenance interval entirely — the site recharges every morning and the hub's internal battery becomes what it should be: a backup, not the plan.
Enormous margin
An Ajax hub is a very light load next to any camera. A single 100 W module with 50 Ah of storage gives so much headroom that a run of overcast days is a non-event, rather than something to calculate nervously.
Room to grow
The same station has capacity left for a 4G router, an IP horn speaker or a camera. A site that starts as an alarm can become alarm plus vision without new infrastructure — the pole and the panel are already there.

Two kilometres from one hub
Jeweller, Ajax's proprietary radio protocol, reaches up to 2,000 m in open space. On a rural property with clear sightlines that is enough to put detectors on the house, the machinery shed, the fuel tank and the front gate from a single control panel.
Or run it on batteries alone
Where a panel isn't practical — deep shade, a covered structure, somewhere a panel would be stolen — the hub runs on batteries alone for years. Figures below are Ajax's published values. Note the two columns: the difference between them is a design decision, not a detail.
| Battery | Type | Capacity | Power saver mode | Full-function mode |
|---|---|---|---|---|
| External third-party | Zinc-air, non-rechargeable | 12 V / 600 Ah | 72 months | ≈18 months |
| Internal NB | LTC ER34615, non-rechargeable | 7.2 V / 190 Ah | 50 months | 6 months |
| Internal NB | LTC ER34615, non-rechargeable | 7.2 V / 95 Ah | 25 months | 3 months |
| Internal RB | LiFePO4 18650, rechargeable | 6.4 V / 78 Ah | 18 months | 2 months |
| Internal RB | LiFePO4 18650, rechargeable | 6.4 V / 36 Ah | 8 months | 1 month |
| Internal third-party | Lead-acid, rechargeable | 12 V / 7 Ah | 2 months | — |
The outdoor range that covers hectares
The hub is only half the story. Ajax's outdoor range is what turns a control panel into perimeter coverage on a property measured in hectares.
MotionCam Outdoor
Outdoor PIR with a built-in camera. Sends a burst of photos on alarm so a monitoring centre can tell a person from a kangaroo before anyone drives out. Anti-masking, pet immunity, weatherproof hood included.

MotionCam Outdoor (PhOD)
Adds photo on demand and photo by schedule to the same detector, so an operator can look at the scene whenever they want — not only when an alarm fires. Ideal for unattended rural sites.

MotionCam Outdoor HighMount
PhOD detector designed for mounting well above head height, which puts it beyond casual interference and gives a better viewing angle across open yards and compounds.
AJAX107890 View product →
MotionProtect Outdoor
Wide-angle outdoor PIR with dual sensors and anti-masking, for yards, compounds and the ground between buildings. No camera, so a lighter load on the system where verification isn't required.
AJAX30658 View product →
DualCurtain Outdoor
Bidirectional curtain detector with two PIR sensors per side, covering up to 30 m along a boundary. Excellent along fence lines and building faces where a wide-angle PIR would false constantly.

Curtain Outdoor Jeweller
Single-direction curtain detector for perimeter runs — walls, gates, shopfronts and the approach to a building. A cost-effective way to cover a long straight boundary.
AJAX107870 View product →
Curtain Outdoor Mini
The same curtain approach in a smaller housing, for discreet installs and tighter mounting positions where a full-size detector would be conspicuous or awkward.

Hood for MotionProtect Outdoor
Weather cover that shields the lens and anti-masking sensors from driving rain and direct sun. On exposed rural sites this is the difference between a detector that lasts and one that nuisance-trips.

Site questions
Will it really reach across a farm?
Often, but verify rather than assume. The 2,000 m figure is open space with line of sight. In practice a machinery shed, a stand of trees or a rise in the ground between hub and detector will reduce it considerably. Use Ajax's radio range calculator during design, then confirm with a signal test on site — and plan for a ReX extender where a distant asset is marginal.
What about cellular coverage out there?
This is the constraint people forget. The hub reports over 2G, 3G or LTE, so if there is no usable mobile signal at the hub location there is no path to the monitoring centre. Two SIMs on different carriers helps considerably, and an external antenna on a 3 m cable lets you place the aerial where signal is best. Check coverage at the actual hub position before quoting.
How often will someone need to visit?
That depends entirely on the battery and the load. A zinc-air external battery in power saver mode can go years; a small lead-acid is a couple of months. Remember Ajax's figures assume ten devices — a busy site with thirty detectors and frequent photo verification will consume far more. Where visits are expensive, either specify generously or pair the hub with solar.
Can it do cameras as well?
The hub supports video surveillance with Ajax and third-party devices, and MotionCam detectors give photo verification on alarm. But photo verification and continuous CCTV are different things with very different power budgets. If the site wants recorded video, plan a separate solar-powered camera rather than expecting the alarm's battery to carry it.
Is it monitored like a normal alarm?
Yes. It reports to Ajax PRO Desktop and to central monitoring stations using Ajax's protocols, with addressable devices and photo verification. To the monitoring centre it behaves like any other Ajax system — the difference is purely that the site has no power.
Which version should I order?
The standard hub in its casing suits most installs and includes the tamper and LED. The board-only version is for mounting inside an Ajax Case, supports higher-capacity internal batteries and an external LED and tamper — worth it where you want the electronics in a larger enclosure alongside a bigger battery.
Important — design guidance, not a performance guarantee
The figures on this page are manufacturer specifications and indicative design guidance. They are not a performance guarantee, a warranty, or a site-specific assessment. Wireless range, battery life and reporting reliability all depend on conditions at the individual site.
In particular, note that:
- Radio range figures are open-space maximums. Buildings, terrain, vegetation, metal structures and weather all reduce achievable range, often substantially. Range must be verified on site.
- Battery life figures are published by Ajax for a system with ten connected devices. Device count, polling interval, photo verification frequency, signal conditions and temperature will change consumption significantly.
- Alarm reporting depends on cellular coverage at the hub location, which is outside our control and can change. Sites with marginal signal require verification and may need an external antenna or an alternative approach.
- Battery performance varies with temperature and age, and non-rechargeable chemistries behave differently from rechargeable ones in Australian conditions.
- Batteries are not supplied with the hub and must be selected to suit the installation.
- Solar performance varies with season, shading, panel orientation, soiling and weather. Solar sizing guidance is indicative only — see the full disclaimer on our solar calculator.
System design responsibility rests with the installer or specifier. LTS Security Australia does not warrant that any configuration will deliver a particular range, battery life, uptime or level of availability, and accepts no liability for loss, damage, downtime, undetected events or consequential loss arising from reliance on this guidance. No alarm system prevents crime or guarantees detection.
Specifications are Ajax Systems' published figures and may change without notice. Confirm current specifications, device compatibility and monitoring arrangements before quoting. Nothing on this page forms part of any contract or quotation.
