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.

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, 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.

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 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.

MPX, IP, wireless, and wire-free security cameras are all powered in different ways. All Lorex MPX security cameras include a Siamese RG59 BNC cable. This cable splits into two ends, one for video and one for power. This allows you to plug the camera in near the DVR, rather than an outlet near the camera itself. IP cameras do not need to be plugged in close to the camera either. They receive their power over the Ethernet cable that is connected to the NVR. This is thanks to Power-over-Ethernet technology. Wireless cameras, on the other hand, are required to be plugged into a nearby power outlet (the wireless aspect of wireless cameras takes place between the camera and DVR). Wire-Free cameras are simply powered by rechargable battery Power Packs. Wire-Free cameras can also be plugged in to ensure constant power.

Wireless cameras are not completely wireless. They still require a power source, which means that they must be plugged in. The wireless aspect takes place between the wireless receiver attached to the DVR and the camera itself. Wire-free security cameras, on the other hand, run on batteries (or solar power), which means they do not need to be plugged in. These cameras typically only turn on if motion is detected. Without a constant power supply, however, wire-free cameras will not provide 24/7 surveillance and will have trouble in high traffic areas since the constant motion will quickly drain the batteries.
