Lorex LH108321C8B 8-Camera Network Video Surveillance System with 320GB H.264 DVR (Black) Review

My intended use for the eight camera system is home monitoring. The capability of watching my home from other locations is an important feature I plan to utilize. This is my first video monitored security system, so my comments will reflect only my observations of this equipment. I have three PCs in my home on a local area network connected to the Internet with a wireless router. I will be attaching the system to a 22 inch monitor.

After unpacking the box I plugged the DVR into the wall and then connected it to my router with the supplied Ethernet cable. Then I plugged the power supply for the eight cameras into the wall and plugged it into the back of the DVR and attached a camera to it. Then I inserted the DVD into my computer thinking it might have some essential software on it I found four buttons, one for the" user manual " (a hard copy of the manual is included in the box,) "acrobat reader" (if not already loaded on your computer so you can read the manual,) "warranty information" and "buy accessories."

When I plugged the DVR into the router it automatically got a network address and then I put the address in Internet Explorer and a log in screen appeared on my monitor. Passwords are disabled as a default, but I'm sure I will change that setting so it requires a password. When completely installed, the screen shows frames for each of the eight cameras.

The first camera I set up was in a pitch black room (it was evening. I wanted to test the night vision. As soon as someone approached the doorway they appeared on the monitor with the entire room illuminated on the screen. In night vision's usual black and white, at a distance of 12-14 feet, a face was clearly visible and identifiable. Frankly, I was wowed -- this was one of those "isn't technology amazing" moments. Next, after temporarily mounting all the cameras, I checked the playback (recording) feature on each camera (automatic default)to ensure that feature was working. So, far, no problems.

Next I needed to get a personal web address to view the cameras remotely from the Internet. On page 44 of the instruction manual the Lorex DDNS website is noted. Once there, I was prompted for my MAC (media access control) address found by going to the "main menu," selecting "advance" and then "info." At that time, a customer server name will also be selected. Perhaps this is obvious, but for security purposes, it would be wise to use something other than the address of the property. The equipment will also be registered at this time, along with a password, user name, etc. After that process is complete, an email will arrive from Lorex with some additional information that is needed to be entered into the DVR to maintain the DDNS connection.

Note, port 80 is used to view the cameras from the Internet outside of your home/business network. The problem is some people may already be using port 80 to host their own website. If you want to change it to a different port, there is information on Lorex's website on how to configure your router to forward to a different port. Then to configure the DVR to use the forwarded port, the instructions are in the user manual - Appendix C. Go to the main menu displayed on the monitor and select "advance", "network" and then use the mouse to change the web port from 0080 to something else. Select a number larger than 1024, in order to avoid using a port that may be in use by one of your other devices. Then to monitor your security cameras from the internet, enter your personal web address and follow it with a colon and the new port number. I checked the set-up from a remote address and it worked perfectly - it looked the same as viewing it on a web browser on the local area network.

Turning the DVR off is a two step process, and it isn't described well in the manual. And, the process isn't intuitive. First hold the button on either the DVR or remote control down until the DVR goes into standby mode which is reflected on the monitor. In standby mode the screen is blank but the lights are still illuminated on the DVR, so to complete the off process hold the power key in until the DVR lights go out and the fan goes off. If you just push the power button on the DVR in and then let go, nothing happens.

If the DVR needs to be disconnected or in the event of a power loss, all of the changes in settings will be lost, including the time and address. Purchasing a UPS (uninterrupted power supply) and plugging the DVR into it is an essential step to protect against power surges and power loss to ensure continuous recording and avoid repeated re-configuration. And, obviously, the user should not frivilously disconnect the system once it is set up.

Batteries are included with the remote control. Note: there are no buttons on the remote control that light-up so when the batteries are dead it will be a matter of trial and error to determine they need to be replaced. I found the remote had to be aimed straight at the DVR. It didn't respond well if the remote was pointed slightly above, below or to the side.

There is no way to mount the camera in a fixed position where it won't move. No matter what I tried there was always a little play. So, if installed outside, a camera will be vulnerable to a strong wind, an object being hurled at it or even a stick being poked at it, so if possible mount the cameras in a sheltered location.

There is approximately 30 inches of cable attached to the camera that is then plugged into the 60 foot cable. For exterior installations, that section of cable needs to be installed inside a wall because the connections aren't weatherproof. Some security cameras run the cable through the mounting bracket so it isn't exposed at the installation site, and thus it is protected from both the elements and an intruder who can simply cut the cable to steal or disarm the camera. That is not the case with this camera, so there is ample reason to install as much as the cable into the wall as possible, leaving little exposed at the installation site.

The stated temperature range for operation is 4 below zero to 140 degrees Fahrenheit. For my purposes this is an issue because in Colorado, it occasionally gets colder than 4 below. So, my cameras will be installed inside the property aimed through windows. One of the photos I attached shows the monitor with four of the cameras installed. The poorest quality of the group is the one on the upper right corner (camera 2) which is currently pointed through a window screen. That camera will ultimately be installed through clear glass, but I included it because even through the window screen, the picture on my monitor is clear and impressive. That street is 135 feet from the camera. For reference, the distances for each of the remaining three shots on the monitor measured from where the camera is mounted to the picture on the screen are 12 feet, 14 feet and the 25 feet. The 25 foot shot is the one pictured in the single monitor screen photograph, and it is quite clear.

Other than plugging in the DVR, no electricity is required in connecting the cameras, so if you have access either through an attic or basement, and a tool to thread the cables through your walls and a drill, it is a viable do-it-yourself project. Dropping the cables through the wall and fishing them down into an unfinished basement and then to the DVR will, in some locations, require more than the included 60 foot cables. On the website, additional 60 foot cables can be purchased for $24.99 each plus $4.50 for the connector needed to attach the two cables together.

Ultimately I am impressed with this system. Granted, it isn't a commercial grade set-up, but for a homeowner, the price is very reasonable and the cameras have a strikingly clear picture, even in pitch black applications. The downside for me is the temperature range, which although broad, isn't quite broad enough for me to safely install the cameras outside. Exterior installation in Colorado might always be an issue considering the number of snowstorms experienced each winter. The cameras might be frequently covered in snow and not provide helpful pictures even if the temperature range permitted installation.

The cameras work beautifully, and the computer set up was smooth. I haven't attempted to contact customer support so I can't speak to their responsiveness. For me, the wiring issue was minor, but that may or may not be an issue depending upon the installation site. So, far I am very pleased with the system. The ability to check on my dogs and my house remotely, and when home, being able to see who is approaching my driveway and front door, is to me invaluable. I don't know how the system will hold up over time, but I will update the review if I run into any problems.

Metabones Contax Yashica Lens to Micro Four Thirds Speed Booster Review

I am really happy about this adapter. Build quality is exceptional. The tripod mount is removable. I have been using it primarily with my contax/zeiss 50 f1.4, 28 f2.8, 21 f3.5 lenses as well as a yashica ML 55 macro. (The Yashica ML lenses are great, and they're great value too) Its maintained a very good image quality, eliminates some fringing, and it appears to be equal to the original zeiss lens quality. The improved f stop gives beautiful out of focus zones (bokah). The result on the above lenses is 35 f1, 20 f2, and 15 f2.5. You really need a viewfinder to focus. I have an Olympus OMD EM5. Awesome. Its fun to shoot again. The kit lens hasn't gone back on.

Product Description

The ASUS HD6950 is factory overclocked to perform 10MHz higher than stock performance at 810MHz. With ASUS' exclusive Voltage Tweak, it promises up to 50 percent faster performance.

ASUS ATI Radeon HD6950 2GB DDR5 2DVI/HDMI/2x Mini DisplayPort PCI-Express Video Card EAH6950/2DI2S/2GD5 Review

Card is built well - it's a reference card, but the HSF cover is aluminum rather than plastic like most, making it more solid and achieving slightly better cooling efficiency. Factory overclock of 10MHz.

Don't bother flashing this card with a 6970 BIOS - potentially dangerous as the memory timings and voltages are different (and this card only has two 6-pin PCIe power connectors unlike the 6970 that has a 6-pin and an 8-pin, so it obviously can't draw the same amount of power). Many report artifacting when doing so as reported by another reviewer. Simply mod the existing BIOS to unlock the disabled shaders (easy with a bit of googling). Then download MSI Afterburner and use that to overclock the card beyond what ATI's control center will allow you. I'm currently running it at stock core voltage with a core clock of 890MHz and a memory clock of 1350MHz with no problems. I encountered artifacting and crashing (only running Crysis, though) when I tried upping the voltage, but luckily that isn't even necessary to give this card a decent overclock. Also, remember to go into ATI's control center, enable AMD Overdrive, and change the Power Control Setting to +20%. You'll have an effective 6970 (or possibly better) for the price of your 6950. As long as your case has good airflow, overheating shouldn't be an issue.

Combine this card with a good CPU, and you'll be flying! Played Crysis at max settings no problem. Granted, I'm only running a 1400x900 monitor currently. That's gonna be my next upgrade...
