Should you get a CCTV system? What distinguishes possibilities for wired and wireless home security cameras? See in our professional guide.
CCTV
For many years, CCTV has been a standard feature in stores, bars, parking lots, and other public places. It’s becoming a preferred option for security-conscious homes due to easy installation and declining costs. The other option is to choose for a complete CCTV system, which typically needs professional installation and operating infrastructure. Or you can choose a wireless security camera that is controlled by an app on your smartphone, which is often a less expensive option.
How to start using CCTV
If you decide to use CCTV, you can either purchase individual cameras or a whole security system. A vandal-proof camera costs about £450, whereas a single wired camera with a 5-meter night vision range costs about £20.
Depending on the type of camera you use, you may also need to purchase connectors and a digital video recorder (DVR) to save and watch the film.
Dummy cameras are also available for about £10. In addition to additional security measures like a burglar alarm, door and window locks, gravel around your property, and security lighting, CCTV is only one line of defence against crime.
types of security cameras contrasted
Cameras
house security cameras with wires These are the most prevalent and most readily recognisable as conventional CCTV cameras. Typically, they are mounted on a wall or other surface outside, and a wire runs from the camera to the display. The drawback is that installing the wires, including connectors and extension cables, might be challenging.
Wireless
Wireless surveillance systems
This kind of system uses digital technology to transport photos from cameras to your computer, tablet, or smartphone. Many modern security cameras can be connected to an app so you can check in on your house while you’re away. However, the term “wireless” only refers to the manner in which they transmit and receive data.
Sometimes a physical wire is required to connect them to the power. Remember that the effectiveness of your camera depends on your home connection. Therefore, if your internet connection drops, your camera’s coverage can be affected. To find out which types we suggest, read our reviews of wireless security camera systems.
All models that have been put through testing have been examined to see whether they can keep you and your information safe from hackers or other people trying to snoop on your house using the camera.

both inside and outside cameras
Whether you choose a CCTV or wireless security camera for the exterior of your home, be sure it is waterproof and has the recommended IP rating of 66.
Although there are battery-powered wireless cameras available, you will typically need to wire the camera to a power source before installation.
Make sure your cameras are placed so that they cannot be altered but can still be serviced and cleaned. Vandal-proof cameras are available, however they are typically more expensive.
There are three different types of indoor CCTV cameras: wired, wireless, and powerline networked. These hook into your electrical outlets and send images to a storage device.
Typically, a wireless model is the best option if you want an inside security camera. Check out our ranking of the top wireless cameras for more suggestions. You may even buy additional cameras and link them together since some variants cost less than £50.
Footage
Resolution of home security camera footage
The larger the number of lines, the sharper the image will be from a CCTV camera. The size and kind of the camera’s chip also affect image quality. In general, smaller CMOS chips, such 1/4″ and 1/3″ CCDs, are of inferior quality than bigger ones. Additionally, cameras with small chips typically have a reduced ability to capture light, which results in lower-quality photographs in dim lighting.
The unit of measurement for light sensitivity is the lux, which can range from 130,000 to 0.001 lux. The camera will record in low light conditions better the lower the lux value. If CCTV footage is to be used as evidence in court, you’ll need high-quality pictures that are sufficiently clear for someone to be recognised.
You need a high resolution for the best detail, but this might increase the cost of the camera and eat up a lot of storage space. Additionally, confirm that the date and time used to “tag” photographs are correct.
features of home security cameras
Storage: A PC hard drive or standalone digital video recorder are used by the majority of CCTV systems (DVR). The fact that PC-connected systems frequently include software to see the photographs is their principal benefit. This feature is also available on several DVR-based systems.
Verify that your system enables you to store photos in a common format, such Mpeg. If photos need to be downloaded and seen on other systems, like those used by the police, there can be issues. Additionally, confirm that the PC or DVR can record high-quality photos if you get a camera that can.
Remote access: With wireless security cameras, you may use a PC or smartphone to see photos online. Notifications of the activation of cameras can also be sent via email or SMS.
Monochrome eyesight at night (black and white) When used with inherent infrared lighting, which some cameras have, CCTV cameras are typically most effective in low light.
CCTV cameras that record in colour during the day and monochrome during the night are an option. The very best wireless security cameras can record video both during the day and at night.
Some CCTV cameras feature a sensor that activates them when it detects movement, which is known as motion detection. If you wish to store less video material, this can be useful. Privacy and CCTV
Privacy and CCTV
If you’re considering installing a home CCTV system outside your home, you must abide by privacy rules.
You should avoid pointing your cameras at public areas, other people’s homes, or gardens. It’s a good idea to talk to your neighbours about any CCTV plans you have in advance. Some members told us that they share a system with their neighbours, which could be a method to save money.
