Lorex FAQ

What Does Lux Mean?

Lux is a unit of measurement that gages the amount of light that falls on an object. In general, one Lux is equal to the light produced by one candle (one meter away). Most of our security cameras are 0 Lux, which means that they are capable of producing a visible image in total darkness with the help of their infrared LEDs. Without the infrared LEDs, Lorex cameras will still typically be able to produce decent video footage without the help of the infrared LEDs with just 0.1 Lux.

Can I Change DVR / NVR Recording Settings?

Absolutely. There are plenty of customizable options on both DVRs and NVRs. Configure general system options, scheduled and motion recording, network settings, display settings, and motion settings. You can also configure recording settings such as resolution and frames per second.

Are Recorded Videos Compressed?

Yes, all of your security footage will be automatically compressed using H.264 Advanced Video Coding (AVC). This will save you massive amounts of data and extend your recording times, without losing any noticeable quality in the footage. There is a big difference between the way analog and IP systems will compress footage, however. In analog systems, the video is compressed in the DVR while IP cameras will compress the data themselves before sending the data to the NVR. It is important to note that our 4K capable NVR (NR900) also comes equipped to handle H.265 High Efficiency Video Coding (HEVC).

What Does Pentaplex Operation Mean?

Lorex security recorders can do five things simultaneously. First and foremost, they will record footage. At the same time, you can view the live feeds, playback recorded footage, backup important files to a USB stick, and remotely control your system from your smartphone or tablet - all without affecting the live recordings.

What Does HDR Stand For?

HDR stands for High Dynamic Range. The purpose of HDR technology is to compensate for high contrast lighting issues (i.e. really bright areas and really dark areas in the same scene). The difference between the brightest section and the darkest section of the scene is referred to as the dynamic range. Cameras with this feature use a special HDR software to help balance these differences. A typical example of when this technology is especially useful can be usually found when using a security camera indoors. On one hand, the inside of the building will be appropriately exposed, but on the other hand, a window in the background will be completely over-exposed (or vice-versa - the camera will be able to see slight details outside, but the interior will be too dark). The HDR feature will try to compensate for this to allow for some visual details outside without affecting the interior lighting. It does this by creating different exposures - over-exposed and under-exposed. It will then combine these exposures to balance the lighting in both areas.

What Kind Of Lenses Do Security Cameras Use?

There is no standard lens for security cameras. Some varieties of security cameras will use one type of lens, while another variety will use a completely different type. In general, lenses can be classified as either fixed or varifocal. Fixed lenses cannot change their field of view while varifocal lenses allow for field of view adjustments within a range. A further important distinction between different types of lenses is the focal length. The focal length (measured in mm) determines the field of view. A shorter focal length will have a wider field of view while a longer focal length will appear more narrow and zoomed in. For example, the ultra-wide security camera uses a 2.6mm fixed lens. On the other hand, the motorized varifocal cameras can adjust their field of view anywhere between 2.8mm (wide) and 12mm (narrow). This allows you to choose either a wide angle view, which will let you seen most of the scene in front of the camera, or a narrow, zoomed in view of one area in particular (like a cash register).

What Does PTZ Stand For?

PTZ stands for Pan-Tilt-Zoom. PTZ cameras come with the ability to look in virtually any direction and zoom in or out. These cameras typically have a 355° rotation, 90° tilt range, and rapid 100° per second panning speed. An important feature of PTZ cameras is the ability to be programmed with extensive monitoring tours. This means that you can manually program the camera to automatically cycle between one important area to another, including zooms. Some models even come with already programmed preset tours that will continuously move from location to location for maximum coverage. You can also manually adjust the field of view of PTZ cameras at any time from any connected smart device or the DVR / NVR PTZ settings.

Do Wireless Cameras Have Night Vision?

Yes. The night vision ranges of Lorex wireless cameras are similar to the wired cameras. This is because wireless cameras receive enough power to operate the infrared lights.

are Lorex Security Cameras Vandal Proof?

Yes, and no. Some Lorex cameras come with an IK10 vandal proof rating, which ensures they can withstand violent impacts. These cameras usually come with heavy-duty metal exteriors and are ideal for lower "within-reach" installations. The majority of Lorex cameras do not come with this rating, however. This is not to say that are totally vulnerable to vandalism though. They all come with durable exteriors (typically lightweight polycarbonate or plastic) and use vandal-resistant designs to protect their cables.

What are the Differences Between MPX and IP Cameras?

The foremost difference between MPX and IP cameras can be found in the way that they compress video data. MPX cameras capture the raw video data, convert it to digital for processing, then convert it back to analog to send it over BNC coaxial cables to the DVR. The DVR will then compress the data using H.264 advanced video coding before storing it to the hard drive. Digital IP cameras, on the other hand, are more like little computers themselves. They will first convert the original analog video data to digital for processing. They will then encode the footage themselves (using H.264 or H.265 encoding) and ultimately send the data over Cat5e Ethernet cables back to the NVR for storage.

Can I Connect a Lorex System to My TV or Monitor?

Yes. All DVRs and NVRs come with both VGA and HDMI video outputs. This allows you to connect your system to your HD TV or virtually any other type of monitor. You can also use both of these outputs simultaneously to view your cameras on two different monitors or TVs.

How Do I Update the Firmware On My DVR/NVR?

You will be required to update your DVR or NVR to the latest available firmware upon system start-up. This is required to enable remote viewing of your system (you will also need to upgrade your client software or mobile apps). When notified after start-up, you will be prompted to upgrade the firmware. Click OK on the page, and enter your system user name (default: admin) and password (default: 000000). The system will then restart once the upgrade has been installed. After this initial set-up, firmware upgrades will automatically be installed as long as your DVR or NVR is connected to the internet.

How Many Cameras Can I Connect to My DVR / NVR?

The amount of cameras you can connect to your DVR or NVR depends on the number of available channels. A 16 channel DVR can connect up to 16 cameras, for example. DVR models typically come in 4, 8, and 16 channel models, while NVR's typically come in 8, 16, and 32 channel models.

What is the Difference Between NVR and DVRs?

Digital Video Recorders (DVR) are analog while Network Video Recorders (NVR) are digital. For the most part, DVRs and NVRs provide you with the same functions, such as recording, motion detection, and remote connectivity. But are fundamental differences, as well. For instance, the way that security cameras are connected and how the recorders receive incoming video. DVRs, for example, receive footage from analog security cameras over RG59 siamese BNC cables. The DVR then encodes the footage (using H.264 Advanced Video Coding) and stores it to the hard drive. NVRs, on the other hand, receive footage that is already encoded and compressed by Digital IP security cameras over Cat5e Ethernet cables.
