Wireless security cameras are a popular choice for homeowners and tenants alike, no messy wiring, no drilling through walls, and setup can often be done in under an hour. But here’s the part that catches many people out:
💬 “If they’re wireless… how do they get power?”
It’s a fair question, and the answer is: wireless CCTV cameras still need power, just not for transmitting video. In this post, we’ll break down exactly how you power wireless security cameras, your options, pros and cons, and the best way to set up a wireless system in your UK home.
🔌 Are Wireless Security Cameras Truly Wireless?
Not exactly. When we say wireless CCTV, we’re typically referring to wireless data transmission, meaning the video feed is sent to your NVR or phone over Wi-Fi, not via a coaxial or Ethernet cable.
However, most wireless cameras still require a power source to function. This can be in two main forms:
✅ 1. Mains Powered Wireless Cameras
These plug directly into a wall socket using a power adaptor.
Pros:
- Constant power supply
- No need to recharge
- Reliable for 24/7 use
Cons:
- Needs a nearby plug socket
- Less flexible positioning outdoors
🔧 Tip: Use wiring accessories to hide and protect power leads for a tidy install.
✅ 2. Battery-Powered Wireless Cameras
These run on rechargeable lithium-ion batteries.
Pros:
- 100% wire-free
- Great for renters or temporary installs
- Easy to relocate
Cons:
- Needs recharging every few weeks/months
- Cold weather can affect battery life
- Limited recording time for some models
Some high-end models like the HikVision: DS-2XS6A87G1-LS/C36S80 (2.8MM) use solar panels to top up the battery, but this is less reliable in the UK’s cloudy climate.
🛠️ Choosing the Right Power Option for Your Home
Here’s a quick comparison to help you decide:
| Power Source | Best For | Needs Recharging? | Installation Difficulty |
|---|---|---|---|
| Mains Powered | Permanent installs, 24/7 monitoring | ❌ No | Moderate |
| Battery Powered | Renters, temporary setups | ✅ Yes | Easy |
| PoE (not wireless) | Full coverage, pro installs | ❌ No | Requires cabling |

❓FAQs
Q: Do wireless CCTV cameras need internet?
Only if you want to view footage remotely or receive alerts. They can record locally to an SD card without internet.
Q: Can I use a power bank to run a camera?
Technically yes, but not ideal for long-term use. Power banks are better for short-term setups or emergencies.
Q: How often do batteries need to be charged?
It varies. Some last 1–3 months, others only a few weeks, depending on usage and motion activity.
Q: Are mains-powered cameras safer than battery ones?
Generally yes. They offer consistent uptime and aren’t affected by cold weather or battery drain.
So, how do you power wireless security cameras? In most cases, it’s either via mains power or rechargeable batteries, each with its own pros and cons. While wireless data makes installation easier, powering your cameras still takes some planning.
If you want a long-lasting, reliable system, we recommend exploring a PoE-based setup like Hikvision's 4K CCTV kits - which deliver the best of both worlds.
