Rain, Runtime and Rig Burn: A British Field Guide to Keeping 360° Kits Alive on Location

Every 360° shoot begins with a conversation about lenses and ends, three hours later, with someone kneeling in wet grass asking whether anyone packed the spare D-tap cable. The unglamorous truth of immersive production is that the camera is rarely the thing that fails. Power, heat, storage and weather are.

This guide is for the small two-person crew shooting a heritage site in Cornwall as much as for the established unit on a six-day venue build in Manchester. The specifics scale; the habits do not change.

Start with a power budget, not a kit list

Before anything is charged, write down what each device draws in watts: every camera head, the recorder, the monitor, the wireless video link, the laptop doing offloads. Multiply by the hours you expect to run. Divide by the watt-hours on your batteries. Then add thirty per cent, because nothing on a British location runs to plan.

A multi-lens rig is hungrier than it looks. Six heads plus a recorder can pull well over 100W, which turns a 98Wh V-mount into roughly forty minutes of cheerful optimism. Bigger blocks — 150Wh, 270Wh — buy you the gaps between setups, but they also add weight to a tripod that is already top-heavy.

Venue power deserves its own conversation. A standard 13A socket will nominally give you around 3kW, but in a church hall that circuit is probably also feeding the urn and the tea hatch. Ask the venue's technical contact which circuits are on protection, whether they require in-date PAT testing for anything you plug in (many do, and it is not a debate you win at 8am), and where the distribution board actually lives.

Outdoors, a small inverter generator will keep a rig and a laptop alive all day. Petrol, ear defenders, and a position downwind of any microphones. Never assume a site has power because it has a building on it.

Batteries: swap early, label everything

The single most useful habit is to stop reading percentages. Voltage sags in cold, and a battery showing 40% on a mild afternoon in Bristol can behave very differently at dawn on a hillside in the Peak District.

Number every block with tape and a marker, log the swap times, and rotate them so nothing gets hammered. Carry at least one dummy battery adapter per camera so you can run from a larger block or mains where available. Hot-swap plates are worth the money if your rig supports them — a two-second swap beats a five-minute reboot and a lost take.

Heat is the enemy you can hear

Thermal throttling does not announce itself politely. It shows up as a dropped frame, a fan that suddenly sounds like a hairdryer, or a recording that stops at twenty-nine minutes for no reason you can find in the menu.

The fixes are cheap. Shade the rig — a golf umbrella, a reflective sheet, a bit of muslin on a stand. Keep an air gap between the camera body and any rain cover. Never wrap a rig in gaffer tape to tidy cables, because you have just insulated the thing you were trying to protect. Check that the fan intake is not sitting against a wall or a bag.

And do not leave a rig in a parked van in July. A metal box in direct sun will cook a camera faster than any shoot day.

Storage: the quiet bottleneck

A multi-lens 360° rig at high resolution can generate hundreds of gigabytes in a few hours. Do the arithmetic on your own bitrate before you travel, not on the train home.

The routine that survives contact with reality is straightforward. Two cards per rig where possible, so one can be offloading while the other records. Offload to two separate destinations, verify with checksums, and never format a card until both copies have been confirmed. An offload laptop should be on mains power, not battery, and should not be the same machine someone is trying to edit on.

If the budget allows a dedicated DIT — even part-time — take it. If not, nominate one person and protect them from being pulled onto set.

Weather: rain, wind, salt and condensation

British location work is a study in water in its many forms. Rain is the obvious one, but sea spray in Pembrokeshire and condensation in a warm venue after a cold morning will do just as much damage.

Rain covers with optical flats keep water off the lens but can soften the image and trap heat, so test yours before the shoot day. A hydrophobic coating on the front elements helps, as does a proper lens cloth and a dry box with silica gel. Dry bags are cheaper than sensors.

Condensation is the one people forget. Carry the rig in a sealed bag and let it equalise to indoor temperature for twenty minutes before you power up. Cold glass meeting warm air is a fogging event waiting to happen.

Wind matters too. A multi-head rig on a tripod is a sail. Sandbag the legs, use the lowest sensible height, and be honest about when a gust is going to take it over. On coastal and exposed sites, rig a safety line.

The one-page checklist

Day before: charge and label every block; format and label every card; test the rain cover; confirm site access and power; check the forecast and have a wet-weather plan that is not just 'we will see'.

On the day: photograph the rig setup before you move it; assign one person to power and media; log every battery swap and card change; keep spare cards in a case that is not a coat pocket.

At wrap: verify both offload destinations before formatting anything; bag and silica the rig; write down what broke, because it will break again next time.

Who owns the problem

Small teams tend to assume everybody is watching the batteries. In practice, nobody is. Naming one person as responsible for power and media — even if that person is also holding a boom — is the difference between a shoot that ends with footage and one that ends with an apologetic email.

The camera gets the credit. The power budget gets the shot.
