The Lorex Edge LH314321C4 is a nicely packaged system with four cameras and a DVR with a 320GB HDD which fulfills the general needs of a home-based video security system. Based on a Linux OS with a USB connector and removable standard SATA HDD, the possibility of a homebrew system is there should anyone be daring enough to try.
Out of the box, the LH314321C4 comes with 60ft of cable per camera and a 10ft network cable which connects to the DVR. All units must feed back into the main system - since this DVR unit has no built in power surge or power backup options, installing it into a UPS or other backup power supply is highly recommended - at the very least, a surge protector. The biggest "oops" in this package is the lack of a VGA cable (or option to connect via a standard S-Video or HDMI). If you actually want to be able to configure and view your DVR, you must supply a monitor with a VGA input (ie: a computer monitor or a TV with VGA out).
You are reading this correctly: out of the box, you have zero way to monitor and configure this system. You must supply your own monitor and/or monitor cable.
Once you get past that hurdle (I had a spare VGA cable lying around from an old KVM set up and therefore hooked up this device to my TV), the initial set up and configuration is relatively simple. The difficulty of the placement of the cameras will of course vary home-by-home, but the 60' radius should be enough for most installations. Also, once this system is actually configured, you probably do not need to have a monitor hooked up to the DVR full time, which is where the remote monitoring option comes into play.
The LH314321C4 has the ability to set up a remote monitoring option which allows your system to connect directly to your local network and by using the Lorex DDNS service, from anywhere with internet connectivity. By using this method, you could hypothetically set up your own secured hosted service (where you would control the security option instead of relying on Lorex as your provider). If you are OK with the somewhat creepy option of having a live video feed into your house on the internet (secured or not), this is a neat feature to allow you to monitor your home while on vacation - or bored at work. By default, there are no audio monitoring options, so if you want sound pick up, you will have to purchase separate components. The device also has an option to plug into an existing home security system by way of a DSub9 connector - since I do not have any sensors with this functionality, I was unable to test. You also have the ability to backup the recorded video onto a PC via their web browser based application.
The DVR functionality was pretty standard - by default the cameras are set up to automatically record video from the cameras. You have the options of changing this to Motion, Alarm or Video Loss (video captured before the camera lost functionality). The included cameras aren't bad - directly from the box mine had quite a bit of red-bleed, but after fidgeting with the hue and saturation a little bit, it was much better. The black and white night vision was actually pretty impressive and seemed a bit crisper than the color daytime version of the video. These are not high-def cameras by any means, and the sample photos on the box are very misleading. These are slightly better than the standard webcam camera, and since the encoding is highly compressed, there's a bit of detail lost. However if you have the misfortune of being robbed, you will still probably have enough facial detail to identify the bad guy.
All-in-all this is a pretty standard system as far as the components are concerned, however the additional functionality added by the remote viewing and backup abilities pushes it past the "average" benchmark. And while the browser based application is rather clunky and cumbersome, it does work (hopefully Lorex will make sure to keep their firmware and software upgrades timely). In my mind, this system lost the five-star mark due to the rather thoughtless lack of a VGA cable and zero sound support. The lack of expansion options (ie: adding additional wired or wireless cameras beyond the initial four) also hurt. Still, for a good ninety percent of the homes out there looking for a DVR-based video security system, this is a good product.
