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.

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:

where to install security cameras?

Keep Cameras Up High

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

Keep under shelter

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


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

Point away from light

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

Protect camera cables

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

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 offers several types of security camera systems, which each have somewhat different installation requirements:

how to install IP cameras

IP Security Camera Wiring

NVR systems utilizing power-over-ethernet (POE) technology only require a single Ethernet cable to connect camera and NVR. This cable provides both power and video transmission. Please see Security Camera Extension Cables for more information on extending the distance of your IP cameras from the NVR.

how to install Analog MPX BNC cameras

Analog MPX Security Camera Wiring

A single RG59 siamese BNC cable connects analog cameras to a DVR. This cable is really two cables in one; one is for power and the other one for data transmission. The video head of the siamese BNC cable plugs directly into the DVR, while the power head connects to an included power adapter. This allows you to plug the cameras in close-by to the DVR, rather than around the camera itself. Please see Security Camera Extension Cables for more information on extending the distance of your analog MPX cameras from the DVR.

how to install Analog wireless MPX BNC cameras

Analog MPX Wireless Security Camera Wiring

Wireless analog cameras typically come pre-paired with a wireless transmitter that connects to the BNC ports on the back of the DVR. This type of camera requires a contant power source and needs to be plugged in to an outlet close to the camera itself.

how to install wire-free security cameras

Wire-Free Security Camera Wiring

Wire-Free security cameras do not need to be physically connected to either a power source or to the DVR. Wire-Free cameras are easily paired with a wireless transmitter that uses a USB cable to connect it to the DVR.

how to install Wi-Fi WiFi security cameras

Wi-Fi Security Camera Wiring

Wi-Fi monitoring cameras are easily connected over your personal wi-fi network. Simply plug the camera in, download and sign-up for the camera's app (please see product documentation), and follow the instructions to add your camera.

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. If you would like to have your system professionally installed, please contact our recognized installation services provider.
