Night Owl WM-845-624 Security System 4 5 1 1
Great price. Iove nearly every aspect of this unit I've had this system about a week. I owned a computer repair and upgrade company 20 years but had to give it up due to health concerns. The learning curve is very steep. Although the manual(s) are ok for folks that are well versed in computers they omit key information that would help one insert or check the proper settings. After I got rather familiar with the 3 settings interfaces (The windows program, the Internet browser program [only MS explorer one or more versions excluded], Chrome [certain versions] and your Android or IPhone cell phone. The cell and Internet explorer do offer as in depth for settings as does the main unit using the supplied stylish l.e.d. mouse. I was so amazed that my cheap 8 meg Huawei Vitra was able to display all 8 channels (at 8 frames/minute/best quality). The cell setup interface is very confusing. It offers a box for you to enter: IP address and serial number with an {SCAN} button to its right. Mine worked after I gave up on entering the serial number and simply put my routers IP address supplied to the DVR. Unless your ISP provides you a never changing IP address (most DO NOT) set up and enter DDNS i.e. yourname or youComanyNam@ There is no need to add or enter the http:// part of the DDNS address) I tried the scan button on my labels but that only messed up the DDNS address. Router setup, port forwarding and so on can be daunting for someone unfamiliar with their router. The easiest way to make sure you unit works via the net (but the least secure) is to use your routers DMZ option. Take note o f your DVRs given IP address. In your setup screen (click NETWORK then LAN and jot down the ip address shown. Then in your router select DMZ and enter that IP address. It's beyond the scope of this review to explain DMZ, UPNP (plug and play) and DHCP. While still in the setup phase, enter your user name and password. The ones that you used to set up your DVR. Example: Admin or admin and the password then click on the 4/8/ or16 ports (how many cameras you have operating). The email area stumped me. Hence 4 stars rather than 5 stars.. Night Owl tech support (OPEN 24 HOURS!) did their best to help me but I could never get the SMTP mail server to send any mail. I used the exact setting I had on my 4 camera system with google that I used on port 465 SSL enabled user name (with the @gmail) and password. No matter if I set it up under yahoo mail or Comcast mail it refused to send mail. I remember reading a section that if a certain item is ticked in setup that it can interfere with email sending. Hence I'm looking for the answer and came upon this page and decided to offer some help to others. I upgraded my firmware as soon as I got my systems cameras hooked up. It's possible data sent via wifi might have got corrupted but more than likely a conflict in a setting. My first inclination was to return the unit but I got a great deal on it and again it shows all 8 cameras very well be it the cell or Internet Explorer. You can even control the PTZ camera from the cell and internet browsers. PTZ stands for PAN, TILT and ZOOM. My unit only PANS AND TILTS but it is so nice scanning until I found my babies (my dogs) snoozing away. I hope that I have helped at least one person.. July 29, 2014
