How to Power an Outdoor Security Camera

Why the power decision comes first

Power is not a detail you settle after choosing a camera. It decides which cameras are even candidates, because it decides the one capability buyers most often assume they are getting: continuous recording. A camera can only record all the time if it is awake all the time, and it is only awake all the time if something is feeding it. That is why every 24/7 camera is wired and every battery camera records event clips, and it is a physical limit rather than a feature tier.

Power also decides where the camera can go, which decides what it can see. Most bad camera installs are the result of mounting where the power was rather than where the view was. Decide the view, then solve the power for that position — that order round, the install is worth having.

1. PoE — one cable, nothing to think about again

Power over Ethernet sends both the electricity and the video down a single Cat5e or Cat6 cable, up to about 100 metres from the switch. The camera has no battery and no mains adapter outdoors, there is nothing to charge, nothing to recharge, and nothing outdoors that needs a weatherproof plug socket. It is also the only route that gives you continuous recording, a searchable timeline on a recorder, and complete independence from Wi-Fi.

What it costs you is an afternoon. You need a PoE switch or a single-port injector indoors, a route for the cable, and a drilled hole with a drip loop on the outside so water runs away from the entry rather than into it. For a run between buildings, use outdoor-rated or direct-burial cable and keep it out of the same conduit as mains. If you are running the cable anyway, run a spare — the second camera always comes later. The PoE-versus-Wi-Fi trade-off in full is in our PoE versus Wi-Fi guide, and the wired field is ranked in our PoE camera roundup.

2. A mains spur — fine if the socket already exists

Plenty of houses already have an outdoor socket by the back door, under a porch or in a garage, and a mains-powered camera on a short, properly rated outdoor lead is a perfectly good install. It gives you continuous recording and never needs charging. A cheap wired camera on an existing socket is frequently better value than an expensive battery camera anywhere else.

Two cautions. Adding a new outdoor socket is electrical work with rules attached, and in most places that means a qualified electrician rather than a weekend — price that before assuming it is the easy option, because it is often dearer than the PoE run. And a mains camera still needs Wi-Fi for anything remote, so a mains spur solves power and not signal. If neither reaches, see our no-internet camera roundup.

3. Solar — the best wire-free answer, with one condition

A solar camera with an integrated or separate panel is genuinely install-once where the panel sees real direct sun: no trenching, no socket, no recharging cycle. For a garden wall, a south-facing gable or a shed roof in the open, it is the right answer and has been for several years now.

The condition is the whole product. A north elevation, a deep overhang or a tree canopy means the panel harvests almost nothing, and you have bought an expensive battery camera you must climb up to charge. Winter compounds it — short low-angled days, and a published charging cut-off that stops a cold cell accepting charge at all, which is the detail in our solar camera winter guide. Where the model allows a detached panel on a cable, use it: let the camera watch the shaded door while the panel sits in the sun.

4. Long-life battery — for the position with no sun and no cable

Some positions have no sun and no plausible cable, and for those a camera engineered around battery life is the honest answer rather than a compromise. Blink publishes two years on a pair of AA lithium cells, which is an order of magnitude beyond the rechargeable field and turns maintenance from a chore into an occasional event.

You pay for it in capability: 1080p rather than 2K or 4K, event clips rather than continuous recording, and a wake-up delay at the start of every clip because the camera was asleep. And check where the clips go — on current Blink kits the bundled Sync Module Core has no USB port and cannot store locally at all, so plan-free recording means buying a Sync Module 2 separately. The storage question in general is in local storage versus cloud.

The two methods to avoid

An indoor extension lead run out of a window.The connection is not rated for water, the window cannot close on it properly, and the first real rain finds the joint. It also puts a live mains connection where a thief can simply unplug the camera. If you need mains outdoors, you need an outdoor-rated socket installed properly, or you need PoE — which is low voltage and immune to both problems.

A USB power bank in a bag. It lasts days rather than months, condenses inside the bag, and fails in the cold. People try it as a trial run and leave it in place; the camera is then dark for most of the time it is needed. If the only available power is temporary, a long-life AA-lithium camera does the same job properly for less money.

A short decision procedure

1. Stand where you want the camera. Decide that is the view, regardless of power.
2. Trace the shortest honest cable route from that point to somewhere indoors with mains. If it is under about 30 metres and does not cross a driveway, PoE and stop here.
3. If there is an existing outdoor socket within a short lead, use a mains camera.
4. If neither, look up at midday in winter. Direct sun on that spot most days? Solar.
5. No sun either? Long-life AA-lithium battery camera, and accept event clips.
6. Now check the Wi-Fi signal at that exact point. One bar means budget for a mesh node, or choose a camera you review on site.

The hardware for each route

The four products below are one per power path rather than a ranking: the PoE camera with optical zoom for a serious wired install, a PoE two-pack for adding cameras at sensible per-camera cost, the integrated-solar pick, and the cheapest competent mains camera for an existing outdoor socket. Their prices come live from the Amazon API and were last checked October 15, 2026. The whole category is at the cameras hub and the scoring rubric at our methodology.
