thanks milkisbad, I'll try that.7 >>>>edit - works great, thanks again. -

Dirk_D replied to Numb-nuts's topic in Installation Help and Accessories
It's not so bad.... lately we use monitors that dangle from the neck, prop on the chest, or hang it from the camera. Much of the time the sun is on another side of the building, or you can turn... not a big problem IMO...of course, sometimes for outdoor cameras, depending on what's being installed, the connections are inside the building so we have to 2 man it anyway at the end. Years ago probably in 2006 I had an eyeglass monitor, it was supposed to simulate a 50" screen at 10 feet or whatever. They looked like what Jeordie Laforge (sp) from Star Trek TNG wore, and they sat high enough on the nose that peripheral vision was still there (see the ladder and surroundings). ......will/way..... -

What do I need to do to view a Hik camera on my phone via wifi using my phones web browser? -

" title="Applause" /> "fixed it" " title="Applause" /> Luckily it defaults to Autotest when the selector switch is completely removed. It only took a few minutes after poking around to see the familiar screens. I think the Fluke CableIQ is what I'd have got if this didn't work, the LRAT seems to be a simplified version of my etherscope, the microscanner2 just doesn't seem to fit my particular needs (I'd like to be able to stress test & store result).

Tom, do you know if there's an Android version of that app? https://play.google.com/store/search?q=+Network+Analyzer+Techet -
sure would be nice to find a retailer who would let me play with these.

Will Cat6 wowrk better than Cat5e for a 350 foot run?
Dirk_D replied to ANiforos's topic in Installation Help and Accessories
direct burial is going to be a mess....I've only used it once at a gas station and it was not fun at all - the cable was heavier & much stiffer, and flooded with some sort of silicone - very difficult to work with. Standard cable in a conduit will be just fine. I guess the direct burial is to protect from damage to the cable & wire insulation from rocks & dirt. Standard cable will fail in underground conduits due to breakdown & then water intrusion, but if you handle it somewhat carefully you should get 10-20 years out of it. 5-8 if you don't, less if you nick it, damage the insulation. -

what don't you like about it, or what doesn't make sense? -

I think so.....haven't tried that. Throw it on the charger between uses if the low battery indicator comes on. It charges fairly quickly and maintains a charge for a good amount of time. As for overcharge protection, it seems to have it. There's a charge indicator that turns off once charged - the instructions warn against leaving it plugged in all the time though. HTH. -
Serious Facial Recognition: Still Snaps?

I've been very impressed with Axxon Next,,,, a few issues, and I haven't played with it for a couple of months, but there's definitely promise with their system. -
I bet you'd be happy with the uni-t, I have 2 of their meggers, and then I also picked up their UT81B scopemeter last year just for fun. I don't know your use/budget, there's lots of options.... the next "cheap" multimeter I wanted to get was the BK precision 2709B but I don't think it's as protected as the flukes (I have lots of yellow & gray meters floating around). I bet you'd like the Fluke 115, I got one for one of the guys that.....I didn't care so much if it got lost. They're (fluke) padded, reliable, and maybe not the absolute best, but they're an easy choice. http://www.amazon.com/Precision-2709B-Auto-Ranging-Multimeter-Millifarads/dp/B004O8Z89C/ref=sr_1_1?ie=UTF8&qid=1405732352&sr=8-1&keywords=bk+precision You can waste a lot of time reading/watching reviews: I bet a lot of the guys here have some reliable ways to test coax..... hopefully someone else will chime in.

to meg the cable, disconnect both ends and make sure they're not touching the ground. Take one lead from your VOM & connect it to a good ground, & then touch the other lead to each conductor in the cable. A megger will kick out 500-5000 volts while reading the same thing (resistance to ground). Ideally you'll get OL, or >500megs to 1+ gig-ohms to ground....... it's an art, so is knowing how to interpret the #s. I sat a bunch of fluke meters (107, 117, 87V) side by side to do comparisons, and they were all surprisingly close, I was reading a ~800K-ohm short to ground at the time.

don't forget to add the fudge factor, and at least one payment on your rocket car made of gold. And the tax man.....never forget the tax man - he'll flatten your tires real quick.

I wouldn't trust your readings. If you got a 0 ohm reading your meter is probably shot. Sounds like you need a little practice/tools/experience. First thing, if you want to test the cable, test the cable. Direct short at the far end (get a feel for it, you should get readings in ....I dunno, I don't test CCTV cables like this (but I test others) no higher than 10 ohms, or in that neighborhood for <200' runs....probably closer to 3-6 ohms. If you try to "test" the cable while it's connected to a camera, you're likely to get 300K-ohms to 1.5meg-ohms, again ballpark but useless #s. I think you'd do better to check the composite video signal voltage. should be ~1.4 VDC, peak to peak iirc I just pulled an analog bnc from an analog dvr to "test" the cable going to a camera, it read ~1.1vdc & ~1.3 meg-ohms.
-
have you megged the cable? That's a quick and easy way to check for that kind of failure. How did you determine the failure? I have a couple of Uni-T 513 meggers, but a decent multi-meter should be able to point out obvious faults.. this stuff really is an art.

I just received a SD42C212S-HN but it came with a defective CD-ROM disk (bubbled label), I've been tooling around on Dahua's site downloading everything that looks promising,,,,,but not having much luck so far. All I know so far is its default ip address is 192.168.1.108 (I haven't changed the ip address on any of my machines yet so I can plug into it that way I was so impressed with Hik's SADP software, I almost expected it to take care of this Dahua camera for me too..... So what I'm looking for is: Dahua's SADP software default username & password http://www.dahuasecurity.com/products/sd404242c212s-hn-456.html http://www.dahuasecurity.com/download_2_2.html

I got it - thanks dexterash. Is there a good program for Dahua that's comparable to Hikvision's SADP? I bot some cameras from the Ne word, seems like they had another program.....I'll have to look for the disks.

RG-59 Siamese Quality Issues

I like your plan - be sure to report how it works. Why aren't you going w/ POE/ IP cameras? Cost I guess This equipment is really getting good and cheap. -
Joystick controllers for PTZ cameras

Not as advertised. Wrong picture, wrong description, wrong linked manual - it's like a car stereo remote with a RJ45 connector on it. -

http://www.ebay.com/sch/i.html?_trksid=p2047675.m570.l1313.TR1.TRC0.A0.H0&_nkw=HVT-2603&_sacat=0&_from=R40 That seems very low price, but again would be limited in functionality but then I suppose you get what you are prepared to pay for. I like to squeeze every last drop of juice out of my devices and although it's like having all the eggs in a single basket I prefer that in this case. The blue charger has a mini-usb charge port, stops charging when it's full from what I can tell (instructions say otherwise). I'd avoid the first one you linked, the ST893 (your second link) will suit you well. The HVT-2603 (skip the one with the "t" at the end of the model #) does everything the ST893 does but has a tone generator, and also an IP Scan function that's really neat - select "scan" in the menu and it quickly lists all the IP devices on your network. -
so I connected to my server from a HTPC, moved 6 movies from one hard drive to another (both SATA, both on the same machine), and I've noticed that the max throughput I seem to get is around 40 MB/second, with this many movies transferring at the same time they ranged from >20MB/sec to 5MB/sec. So I remoted into the server, moved about the same amount, but was getting 150MB/sec. I was doing cut/paste sitting at the HTPC, and since it was taking so long I thought I'd stream a movie from Netflix....... "not taking up any of this PC's bandwidth" I thought... WRONG! The bandwidth to my HTPC was being consumed moving this data. This server is running WHS2011, the OS on my HTPC is win7pro.
