How to Install Security Cameras

Installing security cameras is easy with Lorex. A world leader in Do-It-Yourself security systems, our intuitive products are designed with customers in mind. They feature simplified installation processes that save both time and money. With that said, there are still a few important questions that need to be answered before installation can begin.

What you need to install surveillance cameras

What do I need to install security cameras?

A security system from Lorex includes everything you need to get your system up and running right out of the box. Each camera (whether sold separately or as part of a system) includes the necessary parts to connect and mount your cameras. Each camera typically includes:

  • 60ft of cable (either BNC or Cat5e - per camera)
  • The mounting kit (screws and anchors)
  • A power adapter and/or receiver

Common household tools, such as drills, screwdrivers, and a ladder are also typically required for installation of security cameras, or for making final adjustments and positioning.


Where should I install my security cameras?

Outdoor security cameras from Lorex are weatherproof, meaning you can install them where you need them most. Once you have determined the areas that need the most coverage, optimize installation locations with the following tips:

Install security cameras up-high on ceilings or walls

Place cameras up high

This will protect cameras from vandalism and provide a wider coverage area

Try to install security cameras under shelter to keep it safe from rain and dust

Keep under shelter

This will reduce the impact precipitation has on the quality of security footage

Point monitoring cameras away from the sun or direct light sources

Point away from light

Mount the camera so the lens is pointed away from sources of light

Avoid trees or foliage to maximize home security footage


Don't make obstructions the point of focus to maximize the field of view

Try to conceal all video and power cables for your home monitoring cameras

Protect camera cables

Install on the side of buildings, soffits or ceilings to conceal the cables

Keep home cameras in obvious locations to deter intruders and thieves

Obvious placement

The mere appearance of security cameras can deter potential intruders

All Lorex security cameras come with Quick Start Guides that document how to install them, along with tips and other guidelines. For more on security camera installation and ideas please see our guide on security camera planning and positioning.

How do I connect security cameras?

No security installation is ever going to be the same. The connections each system uses, on the other hand, follow general patterns to make the installation process easier. Lorex typically offers three types of security camera systems, which each have somewhat different installation requirements:

Analog MPX security system installation

MPX analog security system wiring

A single RG59 siamese BNC cable to connects camera, power and DVR. This all-in-one cable provides power and video transmission. The video head of the siamese BNC cable plugs directly into the DVR, while the power head connects to an included power adapter.

How to connect MPX security cameras
Digital IP camera connection

PoE security system wiring

NVR systems utilizing power-over-ethernet (POE) technology only require a single Ethernet cable to connect camera and recorder. The Ethernet cable clicks into the back of the NVR and IP camera. This cable provides both power and video transmission.

HD IP camera installation
Wireless security camera connection installation

Wireless security system connections

There is no need to run video cables through buildings or underground. This also allows you to easily change the cameras location. Connect camera to a power outlet. Then a small wired transmitter attached to the back of the DVR connects wirelessly to the camera.

How to install wireless security cameras

Security camera extensions

The distance between a security camera and the recorder can typically be increased. Each type of security camera does this in a different way. Analog MPX cameras can be up to 800ft away from the DVR using a single run of BNC cable. PoE (or HD IP) security cameras can be extended with the help of a PoE switch, and most of our wireless cameras are comptaible with our wireless range extenders.

Lorex systems are user-friendly and can usually be installed by customers without professional assistance

Do I need an installer?

You may wish to hire a professional to install your security system, however Lorex security systems are designed to be DIY friendly, and many of our customers get them up and running quickly. Our security systems come with detailed installation instructions and include the parts needed to install them yourself.
