CCTV Camera Basics: What You Need to Know
Thinking about adding a CCTV camera to your property? You’re not alone. More households in the UK are turning to video surveillance for extra peace of mind. The good news is you don’t need a tech degree to pick the right system or set it up yourself.
First off, ask yourself what you want the camera to do. Do you need a clear view of the front door, a wide‑angle backyard sweep, or a discreet night‑watch unit? Answering that question narrows the field and saves time when you start shopping.
Types of CCTV Cameras
There are three main styles you’ll run into:
- Dome cameras – blend into ceilings, perfect for indoor areas where you don’t want a flash‑y box on the wall.
- Bullet cameras – long and skinny, they’re great for outdoor spots because they can point in a single direction and often come with weather‑proof housings.
- PTZ cameras – pan‑tilt‑zoom models let you swing the view left‑right and zoom in on demand. They’re pricier but cut down on the number of units you need for a large property.
Resolution matters too. A 1080p camera gives sharp images, while 4K tops that but costs more and needs more bandwidth. For most UK homes, 1080p is a solid balance between clarity and data usage.
Don’t forget night vision. Infrared LEDs let the camera see in total darkness, but make sure the range matches your yard size. Some newer models use color night vision for better detail, which can be handy for identifying faces.
Installation Tips & Maintenance
Most modern CCTV kits are DIY‑friendly. Here’s a quick run‑through:
- Plan the layout. Sketch where each camera will sit, keeping power sources and Wi‑Fi coverage in mind. A wired setup offers stable video but needs a power outlet and possibly a cable run.
- Mount securely. Use the supplied brackets and screw into studs or masonry. A level ensures the frame isn’t tipped, which could skew the view.
- Connect and test. Plug into power, pair with the app, and walk through the live feed. Adjust angle until the key zones are fully covered.
- Secure the feed. Enable encryption in the camera’s settings and change default passwords. This stops random hackers from snooping.
- Check regularly. Clean the lens every few months – dust and rain can blur the picture. Also, test motion alerts and storage capacity to avoid missing footage.
If you prefer a wired system, run Ethernet cables to a PoE (Power over Ethernet) switch. That gives both power and data over a single line, cutting clutter. For wireless cameras, keep them within 30‑40 feet of the router for a reliable signal.
Finally, think about storage. Cloud plans are convenient but cost extra each month. Local NVR (Network Video Recorder) units store footage on a hard drive and usually have a one‑time purchase price. Choose the option that fits your budget and how long you need to keep recordings.
With the right camera type, proper placement, and a little routine upkeep, your CCTV system will become a silent guardian that lets you focus on daily life without worrying about what’s happening outside your door.
