One solid outdoor video surveillance systemBy WayneA few years ago I installed a PC-based security system similar to this fromQ-See in our old house. It was quite a bit more complicated than this all-in-one setup as it involved setting up PC-based Hardware, buggy software, and13 different types of indoor and outdoor cameras.

  6. 6. At the moment, I havent permanently installed the cameras yet, as they aretemporarily placed inside and outside of the house in various locations as Ievaluate the system and determine the best placement. So lets walk throughthe system so you hopefully have a better idea of what youre getting into,and how it performs.UNBOXING:There are 3 separate boxes, in a bigger box. One has the DVR itself andassociated material. And the other 2 larger boxes include all of the camerahardware and wires. The wires for the cameras are 65 and combine both theBNC (for video) and DC power connector into one cable. This should makerunning wires much easier.The end of the cable that goes to your DVR will connect the BNC cable to theDVR, and then the DC power cable connects to a 4-way DC->AC adapter.This is much prefered to the older designs where each camera had its ownbulky transformer to plug into.There is mounting hardware for the cameras, which is rather basic. Youllwant to check this out and make sure its suitable for what and where youare going to mount these cameras into. You definitely dont want themfalling down. Ill get more into Installation later.Theyve also included an RJ45 network cable, RCA cable, Quick Start Guide,and a small USB mouse. The USB mouse is small and cheap, but you can useany USB mouse you have laying around. If you want more instructions, youcan use the included mini-CD which has a full PDF users guide. Or justdownload them directly from Defenders website. I do recommend the latteras I already noticed a few changes between the two. The on-line materialsare more up-to-date.INSTALLATION:While I do have an extensive background in computers, drilling holes andrunning wires is not my strong suite. I neither have the expertise,equipment, or time to correctly install these cameras in the new house. Atleast not to my satisfaction. We just built a house thats 1 year old and has noattic, just limited crawl space. The last house had a huge attic makinginstallation relatively simple. So Im going to leave this to professionalsonce Im ready for installation.

  7. 7. If you want to do this yourself, its important that youre comfortable drillingholes and running cables in your house. The Quick Start guide handilyincludes a drilling template for the mounting brackets. They also instructyou to use a 3/16" drill bit, not included of course. The only tool included isan allen wrench to adjust the position of the camera on the includedmounting bracket.Running the wires and mounting the cameras is generally considered the"hard part." Youll want to make sure the compact DVR is in a locationwhere it has network connectivity (for remote viewing) and of course,power. Sorry, no WiFi here.If you want to have this professionally installed, this can get rather pricey.From shopping around my area, youre looking at anywhere from $100-$200 per camera depending on how much labor is involved and how manyyou have. This is assuming you want it done "right," and not just have awires and holes all over the place. The good news is that the more you have,the less they normally charge per camera.CAMERAS:Before talking about the DVRs, we should spend some time on the camerasthemselves. Ive used equipment ranging from cheap (and useless) $40cameras to some very nice setups getting past $300+ a piece. As is often thecase, you certainly do get what you pay for.These are surprisingly fairly decent outdoor day/night cameras. Id expect topay around $100 a piece with cables for the quality Im seeing here, so its apretty good value with the DVR. There are 36 IR (Infrared) LEDs that willglow red at night, which provide the night vision. These are going to be quitevisible from the street and should provide a nice deterrent on their own. Notto mention they just look cool. :)They are advertised at 100ft night vision, but realistically, youre looking atroughly half that. Mostly because any further than this, and you really arentgoing to have any idea what youre looking at. However, if there is someambient light such as a street light, your range will naturally extend quite abit. But in 0 lux (complete darkness), it is more limited. Of course for homesurveillance, that is really more than enough.I did most of the testing in my backyard as it gets completely dark out there This page is a participant in the Amazon Services LLC Associates Program, an affiliate advertising program designed to provide a means for sites to earn advertising fees by advertising and linking to Amazon.com
  8. 8. at night. I watched as it went from light to dark, then again in the morning,when it got bright again. And the transition from night vision (B&W) to daymode (Color) was seamless. And then tested to see if we could identifysomebody (such as myself) approaching from a distance at night.For realistic identification, the subject will really need to be within about 20-40 ft in complete darkness, depending on conditions. In the daytime, this ismuch further of course. This is further limited by recording quality. More onthat in the DVR section.One last important note for the camera is how it switches from Day/Nightmode as the camera itself makes a surprisingly loud clicking noise when itmakes this change. Not a big deal if they are outside. But inside, we can hearit clicking a few rooms away. Not to mention being inside, where its darker,it switches between day/night mode much more frequently. Think partlycloudy skies where it becomes light and darker throughout the day.DVR:The DVR is what makes this package much easier to manage and setup as ithandles everything for you. I have all of the cameras plugged into the box, akeyboard, mouse, a monitor via its VGA port, and a network cable. The USBmouse/keyboard are optional, but are recommended for initial setup. Youcan switch to the IR remote afterwards.If youre comfortable playing with the setup menus for your TV or othersimilar electronics, you should be able to figure most of this out on yourown. The interface is primitive to say the least, but very functional.Otherwise, I do suggest browsing the users guide before even plugging it inas there are quite a few options you may not be familiar with.It would take a while to go through every option, so if you dont have oneyet, you can check out the owners manual. The important features areadjusting the display, setting up record schedules, motion detection, filesizes, search for recorded video, user accounts, and network (LAN only)setup.The "live view" of all the cameras is what Id expect from this setup. You canswitch cameras, change grids, pause the video, rewind, etc. The image lookspretty darn good and are certainly right about "DVD Quality." However,what you see on the monitor isnt exactly what you get when you playbackvideo, which is slightly lower quality. But still very useful for seeing what This page is a participant in the Amazon Services LLC Associates Program, an affiliate advertising program designed to provide a means for sites to earn advertising fees by advertising and linking to Amazon.com
  9. 9. went on when you were out.The claim is that you can get 2 years worth of footage on a 500GB HD. Evenif youre adding up each cameras footage together and lower the quality andFPS (Frames Per Second), thats a bit of stretch (and not all that relevant.) Isuspect if you got it to last that long, the quality would be pretty bad.Normally youre looking at 2 weeks, not 2 years. At the default rate of 30fpsand 768 Bit Rate, which is the highest, the drive is already half-full. Bydefault it will auto-overwrite old content.Thats certainly not a negative, I just want everybody have realisticexpectations as I thought the description was a bit misleading as they werereferring to "total footage." Although you can connect an external USB harddrive to extend recording and even copy videos from the internal drive. Youcan even setup recording schedules or "motion activated" recording tostretch things out quite a bit. Thats very handy, of course.REMOTE VIEWING:You will need to go through network setup and create at least one useraccount with a password. This is important to note. Out of the box, if youjust setup your network only, you can remotely view the cameras from yourbrowser. For PC users, you are limited to Internet Explorer only. I used IE9as IE8 never would install the plug-in. FireFox and Chrome are detected asincompatible browsers and wont work. And you will have to make atemporary change to your IE security settings to allow the plugin to install.I also suggest setting up a "Static IP" with the DVR versus "Dynamic IP,"which is the default setting. As the names implies, a static IP will ensure theIP address doesnt change occasionally when you have to reboot the deviceor router. Just check your router documentation to see what IP would workfor you.To access the web portal, I entered the static IP I configured earlier, intoIE9, http://192.168.1.9, installed the plug-in, and then login with the defaultlogin/pass, (admin/admin). You should change this later. In addition toaccessing the cameras in near-real time, you can access most settings hereas you would on the DVR directly. If you want to do this outside of yourhome network, youll need to make a few changes to your router to opensome ports.However, the DVR does support UPNP (Universal Plug-n-Play). If your This page is a participant in the Amazon Services LLC Associates Program, an affiliate advertising program designed to provide a means for sites to earn advertising fees by advertising and linking to Amazon.com
  10. 10. router also supports this, and its enabled, it will open the ports for you. Mynetwork setup is a bit more complicated and doesnt support this as itsoften considered a security risk. I wont go into too much detail otherwise Illnever get this review finished. So, Google it. :)Otherwise they do have some fairly decent instructions to walk you throughmost of this stuff. Since the way you do this does vary between routers,theyll refer you to the documentation that came with your router. Also onceyou open the ports, youll definitely want to make sure passwords have beenchanged and set.You can even use your SmartPhone to remotely connect to the DVR andcheck out the cameras. You will need to go into the Users accounts screenand either create a new account or enable the password for one of theexisting accounts. This is important as the default credentials wouldnt workfor the app, only web. Although once you have user accounts setup withpasswords, you can specify who has permissions to access various features,and they will work for both web and phone access.REAL-WORLD USE:So how does it really work? For the most part, it works very well. At leastonce you have everything installed, configured, and setup. :) This is certainlymuch easier to setup than it was years ago with the older PC-based setup Iused quite some time ago. My wife and I really do enjoy being able to glanceat a second computer with the cameras running. Is somebody at the door?Noise in the backyard in the middle of the night? Want to check on thehouse while youre out? Not a problem.The remote viewing quality isnt as good as it is on the DVR itself, especiallyon the phone app, but still good enough for its intended purpose.All of this combined with a monitored security system and few guns layingaround, and youve got a one secure and protected house! Of course nothingis 100% secure, and you should always use some common sense; but having8 red glowing cameras around the house serves as one heck of a deterrent. :)I did run into an issue where the DVR decided to ignore any type of inputfrom the mouse or remote control. There arent any buttons on the deviceitself, so a power cable pull was needed for it to reboot and start respondingagain. At least the timer was still going and it was still recording.

  11. 11. So thats not a big deal for now. Otherwise its been running smooth andquiet, providing what is essentially real-time monitoring and recording ofthe premises.Lets wrap this one up.PROS:+ Great value with DVR & Cameras+ Good quality day/night cameras+ 500GB DVR+ Remote browser and phone viewing+ Relatively "easy" setup process+ Generous cable length and basic HW included+ Fast DVR for near real-time viewing+ Universal Plug-n-Play Supported+ USB Storage CapabilityCONS:- Limited browser compatibility- Recorded video quality could be a bit better- Noisy Day/Night "Clicking" from Cameras- No WiFi- Cheap mouse?CONCLUSION:So this review ended up being a bit longer than expected, but there is a lotgoing on here with a video surveillance system. And theres a lot of smallerdetails that would take a Users Guide to cover. So Ill leave that to the oneDefender already wrote, which is better than most Ive skimmed in the past.:)Overall, its not perfect, but if youre looking for a good mid-range outdoorday/night DVR system for your home or small business, I consider thishighly recommended and give it a solid 4.5 stars.78 of 80 people found the following review helpful. Solid 4 stars, with 5-star potentialBy R. PrecourtIve been on the fence about buying one of these systems for a little over ayear now and finally decided on this one. This page is a participant in the Amazon Services LLC Associates Program, an affiliate advertising program designed to provide a means for sites to earn advertising fees by advertising and linking to Amazon.com
  12. 12. My needs were:* 4 outdoor cameras* Good resolution* Good night vision* DVR with network capability* Ability to view cameras from multiple computers and smartphone* Price range of $300-$350This system appeared to meet all my needs and I had noticed over the pastyear that the Defender systems seemed to have the best overall ratings. Ifurther researched the on-line manual for this system (as I frequently do forthings that Im serious about purchasing) and it also gave me comfort thatthe system would meet my needs.Ive had the system installed for about a week now and I am quite pleasedwith it. That being said, I would like to share my overall experience witheveryone, as it may be helpful for those considering this system andinstalling it themselves, as I did.I did a few things backwards, but found it helpful in adjusting the camerasonce I had everything wired.First off, the entire system was packaged very nicely - great presentation andwell organized. All of the camera cables were rolled up nicely on plasticspools. All parts were neatly arranged and well labeled.Next, I took everything out of the box and hooked up to my 40" SamsungLCD via VGA cable to test it out. Note: the manual indicates that if you hookthe DVR up using VGA to an LCD TV or monitor that the mouse and remotewill not function. I called Defender to inquire about this prior to purchasingand they informed me that the unit WILL work fine via VGA and they werecorrect. I have no problem with the mouse or remote working using the VGAport and this gives great resolution (much better than using the compositevideo cable.) The VGA cable is not included with the system, but all othercables you need are. I would recommend using VGA if you can.After hooking everything up for a test run, I found that everything workedfine. I did notice that the video connections on the back of the DVR seemedto be a bit loose, causing the video to flicker and go in and out if I moved tocables, however, once I had everything hooked up and running I have notexperienced this again.

  13. 13. I then proceeded to configure the system and do the network setup, firstly,to verify that it would actually work and do all the things I wanted, andsecond, so that I could view the cameras from my Android phone whileadjusting them, which is very helpful and allows for an easy, one-personinstallation.I had no problems at all with the network setup and port forwarding on myAT&T U-Verse router/gateway. I simply set the DVR to DHCP and let itacquire an address. I wrote all the acquired information down, then changedit to Static and input the same information (so that I dont have to worryabout the IP changing. I forwarded the three ports needed for network andmobile viewing and was viewing on my phone within minutes. Defendersnetwork guide was great and made the whole process very easy. I added theIP address to the trusted sites zone as directed and set security for trustedsites to low and had no trouble with the ActiveX install.The on-line software is very nice and allows you not only to view yourcameras on any computer, but also you can manage every setting on theDVR, just as if you are right there. And, its actually easier (in my opinion) todo this via the software, than on the DVR itself, although the DVRs interfaceis also easy to use.Now, on to the installation; here are the things that I experienced that Ihope will help future buyers install this system with less pain than I had.I dropped all of my cables from the attic down into the wall behind my flatscreen TV and routed them through an AV wall plate, along with the othercables that were already there (HDMI, VGA, power, etc.) Here is oneimportant thing to note; the cables are neatly spooled up, so naturally Iunrolled them all in the direction that they were spooled. While the BNCvideo connectors are the same on both ends, the power connectors are NOT;they are male on one end and female on the other. AND, two out of four ofmine were spooled backwards. This caused me to spend an extra day re-running one cable completely, which I had run all the way to where one ofthe cameras would be on the other side of the house, down through anothervery difficult wall to the first floor. I did not notice the problem until I wentto plug the camera into the cable and ended up with two female plugstogether. So, long story short - pay careful attention to the orientation of thepower connectors and make sure you run the cables in the correct direction(the female end should start at the DVR and the male end should be at thecamera where it will plug into the female jack on the camera.

  14. 14. After getting over that, I got the cameras all mounted and hooked up.Another thing to note is that these cameras can only be wall or table-topmounted, but not ceiling mounted, so if your application requires this, youwill need different cameras. I think some of their other cameras can beceiling mounted, but not these.The wiring goes through the mounting bracket, which is very nice and thereare slots in the top and bottom if you have to run the wire differently, as Idid with three of mine (up into the eves and into the attic.) If the camerascould have been mounted directly to the eves, this wouldnt have beennecessary, but it all worked out.The next thing Ive experienced that may be helpful to know before youmount the cameras is that the screws provided are NOT weather-resistantby any means. While the cameras themselves appear to be made very well,my screws have already began to rust after only two brief rain showers andless than one week of being outside. Easy solution - buy some exterior gradescrews from a hardware store. I did this, but again, I had to climb back up toeach camera and remove and re-install each one. I hope this saves someonea little time.Also, while setting up your cameras, heres another thing to look for. Thefirst night I had my system working, I noticed halos in the lower part of thescreen when the night vision was active. It was more noticeable on one ofmy cameras, especially when it was very dark outside (like when the streetlight across from my house would go out due to the bulb dying.) At first, Ithought that this problem was being caused by another street light furtherdown shining into that camera. I made adjustments the next day andchecked the following night - same problem. After doing some research on-line, I found people mentioning that halos can be caused by the IR beingreflected back to the camera from a nearly object, like a window forexample. Since there were no objects anywhere near my cameras, my onlyother thought was that maybe the IR was reflecting off the sun shades of thecameras themselves. I slid each one back about an inch and checked -SUCCESS! No more halos, so this is another thing to check when installingyour cameras. Instead of having the back edge of the sun shade flush withthe back of the camera, try sliding it back about an inch and you should begood. Now I have crisp, clear night vision.Each camera has a horizontal and vertical adjustment screw, which can beloosened or tightened with the included allen wrench. While the horizontal This page is a participant in the Amazon Services LLC Associates Program, an affiliate advertising program designed to provide a means for sites to earn advertising fees by advertising and linking to Amazon.com
  15. 15. adjustment has definitive `notches or `stops, the vertical one does not.This requires you to have to tighten the screw quite tight in order to keep thecamera stable. I wish that both were notched, as I had trouble with one ofmine. The screw seemed to start slipping and I ended up using a little crazyglue between the joint to keep it stable, once I had it positioned the way Iwanted. Then I simply tightened the screw as much as I could and it seemssolid now.So, Ive been using the system for about a week now and really like it. I hadplayed with all the settings, and have it set to record all channels 24/7, withmotion recording between 6:00 am and 8:00 pm. It has the capability to e-mail you whenever motion is detected, along with a snapshot of the event. Ittook some playing with it to get the motion settings more accurate and nowits pretty good. You can select specific areas of the picture to look formotion, like just the front porch steps, for example. I found that even theshadow of sunlight through the leaves of a tree moving in the breeze willcause a motion alarm, so its important to only select the areas that youneed.With recording 24/7 on all channels, at 15 FPS and 1280 bit rate, I can storea little over a week of footage on the hard drive. I elected for better qualityover being able to store more hours of recordings. For my needs, this will befine, as Ill likely know of any events that occur that I need to download,which you can do through the on-line software or from the DVR itself. Themanual mentions being able to connect an external hard drive, but I havebeen unsuccessful at getting one to work. Ive heard that you can upgradethe internal drive to 1.5TB, but apparently doing so will void the warranty,so I guess the 500GB drive will have to do.With these settings, my recorded video quality is very good. When youdownload a video file, the quality is also excellent. What I have foundlacking is that when you take a still image snapshot from a video, the imagequality is not as good, as it saves the image as 704x480 pixels. When you tryto zoom in on a still image it gets distorted, whereas zooming a video is notas bad. What I have found to work better is to play the video and resize thewindow to the desired size, then take a screen shot from there and save it.This works much better and retains better resolution.All and all, this is a solid system at a great price. The 600 TVL cameras arevery nice, with great night vision and the DVR is feature-rich, very small,and very quiet (I have it in my master bedroom in my media cabinet andcant hear it running at all.)

  16. 16. Below are my final thoughts:Pros:* Good quality outdoor cameras with great night vision and 600 TVL* Feature-rich DVR with network capabilities* Ability to view and set all functions from any computer* Ability to view cameras live on smartphone* Compact size and quiet operation* Good build quality (except camera mounting screws, noted below)* Easy connection of cameras, with power and video in one cable* Long cable length provided (65 feet) allows for flexibility of installationlocations.* Everything needed is included in the package* Excellent price pointCons:* Camera mounting screws are not weather-resistant and will rustimmediately* Cameras cannot be ceiling (or under-eve) mounted* Position of timestamp cannot be selected - only displays at top of screen,or off* E-mail alerts for motion evens do not adhere to motion recording scheduleNote: I have written to Defender regarding all of the above and they advisedthat they had forwarded these concerns to their R&D people. Not sure if anyof these issues will be addressed, but we can hope.I give the system a solid 4 stars, easily with a 5 star potential with these fewminor issues resolved.I would highly recommend this system to anyone looking for a quality,feature-rich surveillance system at an affordable price.53 of 59 people found the following review helpful.
