Lorex Technology was founded in 1991 in Markham, Ontario, Canada, as a manufacturer of consumer and small business security camera systems. FLIR Systems acquired Lorex in December 2012 for approximately $59 million CAD, rebranding products as "Lorex by FLIR." In February 2018, FLIR sold Lorex to Dah...

Lorex Camera Motion Detection Not Working or Too Many False Alerts

Device: Lorex Security Camera System (Lorex 4K E893AB, 2K W462AQD, Wire-Free W262AQB, Fusion 4K NVR systems)

Your Lorex security camera does not detect motion events, misses recording triggers, or sends excessive false alerts from trees, shadows, vehicles, or weather. Lorex motion detection relies on pixel-change analysis and optional AI detection — either the detection zones are not covering the right areas, the sensitivity is miscalibrated, or AI filtering settings are not correctly configured for your scene.

Lorex NVR Not Detecting or Showing Cameras After Setup

Device: Lorex NVR Security System (Lorex N841, N842, N844, N861B, N862B, Fusion 4K NVR)

Your Lorex NVR does not show any cameras after initial setup, shows cameras as offline, or can only detect some cameras but not others. NVR-camera connection failures are typically caused by PoE port issues, IP address conflicts on the local network, or the cameras and NVR being set to incompatible network configurations.

Why Are My Lorex Recordings Missing or Corrupt?

Device: Lorex NVR/DVR (All Models)

Your Lorex security camera recordings are missing or showing as corrupt during playback. Check the recording schedule and channel assignment first — each camera channel must be configured for continuous or motion recording in the NVR/DVR settings. Missing recordings may mean the schedule doesn't cover that time, or the hard drive is failing.

Why Won't My Lorex Camera Record?

Device: Lorex Camera (All NVR Systems)

Your Lorex camera shows live video but isn't recording to the NVR - the playback timeline is empty or has gaps for that channel. Recording depends on the channel's schedule and recording mode, a healthy hard drive with overwrite enabled, and (for motion recording) correct motion/smart-detection settings. This guide covers checking the schedule, storage, and detection so the camera captures footage.

Why Does My Lorex Camera Have IR Glare?

Device: Lorex 4K Security Camera (4K NVR, Fusion, Wire-Free Camera)

Your Lorex camera image has a white glare or haze at night caused by infrared (IR) light bouncing off nearby surfaces. IR glare occurs when the camera is mounted too close to a wall, under an eave, or pointed at a window. The IR LEDs reflect off the surface back into the lens, washing out the image.

Why Did My Lorex NVR Hard Drive Fail?

Device: Lorex NVR (4K NVR, Fusion, Wire-Free Camera)

Your Lorex NVR's hard drive has failed or is failing - it isn't recording, reports a disk error, isn't detected, or playback is corrupt. NVRs run their surveillance-grade drives 24/7, so drives do wear out over years of continuous writing. This guide covers confirming the failure, recovering a drive that's only unrecognized, and replacing it with a proper surveillance-grade drive.

How Do I Set Up the Lorex WiFi Camera?

Device: Lorex WiFi Camera (4K NVR, Fusion, Wire-Free Camera)

You are setting up a Lorex WiFi camera for the first time. WiFi cameras connect to your network wirelessly instead of through an NVR Ethernet port. Battery-powered models need a full charge before mounting. This guide covers charging, WiFi pairing through the Lorex Home app, and mounting.

Why Is My Lorex Camera Showing No Video on the NVR?

Device: Lorex Security Camera (IP Cameras, Analog Cameras)

Your Lorex camera shows no video on the NVR - a black screen or 'No Signal' on that channel even though the camera is connected. On a PoE system the camera gets both power and data through one Ethernet cable to the NVR's PoE port, so no video usually means a cable, PoE port, power-budget, or IP issue. This guide covers isolating the cable/port, confirming power, and resolving IP conflicts so the channel comes back.

Lorex Camera Night Vision Blurry or Black and White During the Day

Device: Lorex Security Camera (Lorex 4K E893AB, E896AB, 2K W462AQD, Fusion 4K LNF2924B)

Your Lorex security camera shows blurry or grainy night vision footage, stays in black-and-white mode during daylight hours, or the IR LEDs produce a washed-out overexposed image at night. The most common cause of daytime black-and-white is a stuck IR cut filter — the mechanical filter that switches between color and night modes failed to flip back to the day position. A power cycle resets the filter in most cases.

Why Won't My Lorex Remote Viewing Work on My Phone?

Device: Lorex NVR/DVR (All NVR and DVR Models)

You cannot view your Lorex cameras remotely on your phone when away from home. The Lorex Home app shows the system as offline or times out when trying to connect. Remote viewing requires the NVR to have an active internet connection and either Lorex cloud connectivity or port forwarding configured on your router.

Why Is My Lorex Camera Image So Dark?

Device: Lorex Camera (4K NVR, Fusion, Wire-Free Camera)

Your Lorex camera image is too dark - underexposed in daylight, or so dark at night that you can't make out detail. Dark images usually come from exposure and image settings (brightness, WDR, backlight compensation), a scene the camera can't balance (bright sky behind a dark subject), or failed IR at night. This guide covers the settings and placement fixes that brighten the picture.

How Do Lorex Smart Deterrence Features Work?

Device: Lorex Camera (4K NVR, Fusion, Wire-Free Camera)

You want to use the Smart Deterrence features on your Lorex security camera. Smart Deterrence activates warning lights and a siren on compatible cameras when motion is detected, deterring intruders before they reach your door. Not all Lorex cameras support this feature — it requires cameras with built-in spotlights and speakers.

What Do I Do When My Lorex NVR Hard Drive Is Full?

Device: Lorex NVR (4K NVR, Fusion, Wire-Free Camera)

Your Lorex NVR's hard drive is full, and you're unsure whether it will keep recording or whether you're losing footage. On a properly configured NVR, a full drive should auto-overwrite the oldest recordings and keep going - so if recording has stopped, overwrite is likely disabled. This guide covers enabling overwrite, understanding retention, and adding storage if you need to keep footage longer.
