Nice! How many amps does your charge controller run? I imagine even 10A controller is well above what your PV panel is pushing out.

Decent IP Cam with good night vision for baby monitor
zr1 replied to MikeRatcliffe's topic in IP/Megapixel Cameras and Software Solutions
The fast-n-simple-(and kinda low cost) is one of the myriad of wifi cams out there. Nest Cam was one of the big advertisers, but there's a zillion cams out now just like them and do just as well for less cost. Wifi cams are typically indoor cams, and being Wifi, easy to plug in and go for viewing from the smartphone. But on the down side, wifi is not a solution for install and forget for months and months...they disconnect once in a while meaning a reboot (typically they'll go days or weeks without a needed reboot). But for the reliable better-than-99.99% solution, it means a wired solution. A nice IP camera (such as Hikvision as we see on here mentioned many times) wired via Cat5/6 cable to your network. Some of these do have SD-card recording on the camera and you can log in on the camera directly. Or you can use an NVR for more storage and other options. I've been liking Hik's "Exir" series for general use. -
Looking for standalone direct to tv PTZ camera with Controlr
zr1 replied to cwyatt89's topic in Security Cameras
Something has to control the PTZ and that means either a DVR or a PTZ controller (joystick, etc.) And that's how we used to do it (still do on some applications or retrofits). But at this year's Vegas show, there was a whole bunch of "mini IP PTZ domes" out and for a whole lot less than PTZ cameras used to be (Dahua had quite a layout, but also a bunch of lesser-known brands too). Even on Amazon, there's a bunch of them in the $200-300 range. Quite a few of them are doing 4x-10x optical. But there's also some 20x optical cams. Then with the higher resolution, many cams allow for digital zooming. Lay your Cat5/6, plug it into the router...everything else is simply controlled from the computer or smartphone/tablet. Even power it from a POE switch (or single POE injector). None of that 24 volt stuff, no separate RS485 wire. If it needs to be on the big screen TV, if the TV has USB input to handle something like Amazon Fire TV, then one of the Android-based USB dongles can typically get the right app and it can be controlled from the TV and a remote control. Still a bit of research to match it all up, but it's some good times we're living in! -
D1 resolution using H.264 at medium quality settings @20fps 24/7 (no motion activation) 12TB is around 55-60 days of recording. +1 on the TVI (or other high-def analog formats..AHD, SDI, CVI, etc.) They look really good and are a huge step up for the cameras that you add on (or replace). About 2 megapixel-ish, which looks great. True, IP cams go above that. The big advantage of retrofitting with TVI (etc) is cost and time where you wouldn't have to redo all your cabling and simply reuse your existing coax cable. The higher resolution does mean more storage space. And of course the cameras these days are all adjustable with so many settings to balance the data storage and image quality. Whether you run a single 32-channel DVR, or run two 16-channel DVRs and use a CMS tool to manage everything on one view. And some people even run two DVRs and simply log into whichever one they need. It goes more toward the workflow of the company and what is more efficient for them. As for which of the high-def analog formats, it'll be up to you. To me, I always thought SDI gives a slightly prettier image (even though they're all 1080P-ish). I've been focusing on TVI lately because it's easier to stock tools and inventory just for one. I do like that TVI is real flexible on cameras/DVR's from different brands without a hitch (that I've found). TVI is also an open standard (as is SDI and AHD) while CVI is proprietary to Dahua. Dahua is awesome, I just didn't want to hitch up to a single company. And last, TVI has that 1600 foot cable run capability (as does AHD). Is TVI the best? Probably depends on the situation more. But I do like it for: * retrofits * jobs where the cable runs are reallllly long

Security camera setup advise for self storage buildings.
zr1 replied to svencam's topic in System Design
The Hikvision cams and NVRs that I've been using in Arizona, they've dealt with the heat well. 95% of the time, the NVR is indoors, but for the few that have to live without air conditioning, they still work fine. But I do keep them in the shade. And I do install a fan on whatever enclosure or the NVR will heat up the enclosed space higher than the 115 degrees that it is outside. Hard drives and POE switches do ok, but they do have to be replaced more often (every few years). -
New to the forum and have a few questions I hope I can help
zr1 replied to edteach's topic in System Design
Yup, the little wifi cams do get a lot of capabilities. They still have the wireless issue of going offline, but such is the nature of our wireless at this time. I haven't worked with the SNH-P6410BMR before. I've done the SNH-1011 that people have bought and wanted me to con-fiddle for them. They do remote viewing, they do record, and the little software gizmos. One annoyance for the smartphone app for the SNH-1011 though is it won't show more than one camera on the screen at a time. -
New to the forum and have a few questions I hope I can help
zr1 replied to edteach's topic in System Design
There's multiple options to choose from that should work fine. For that kind of money, you may be looking at individual cameras that record to an SD memory card. Depending on the size of the memory card, the bitrate of the video quality you set it as, and whether you set it up for motion-only recording...then you may get several days to a week or two of recording out of such a setup. Going with a setup with a DVR/NVR, then you can add whatever size hard drive to the DVR/NVR and get a whole lot more storage. The DVR/NVR would go over your budget though. Then again, a quality system goes over the budget as quality systems just aren't that low cost. Back to budget...Yeah, you could do a few 1-2 megapixel (720P or 1080P) cams. And you'd be able to see them on your smartphone...most all of them do that these days. Depending on the smartphone app...you may be able to see all cams on your phone on one screen. Some apps though only show one cam at a time. Wireless In 2016, it's simply not as reliable as wired. So every week or three, a cam will go offline and you'll need to reboot it, etc. And even with a wireless cam, you'll still need to get a wire to it for power. Budget #2 You could go down (way down) to D1 or 960H on your budget...but that's like crap video...1930's era of video quality. Stay with either IP cameras or go with a High Def version of analog (SDI, TVI, CVI, AHD, etc.). An issue with one of those alphabets is that once you go down that road...then you stay on that road. If you get CVI, then you stick with CVI (unless you start over). -
Very well done! I like it! For some of my remote construction site projects, I've been using some Dahua 12v PTZs as I don't have a generator handy (solar + batts...which is kinda pricey$$$), so I try to keep the juice-usage low...so I just stay 12v DC and avoid the DC-AC inverter altogether. But if you've got an engine, whether the vehicle engine or a gas generator, then sure, go with the inverter setup. Winching (not the Pirate version...y'arrrrr!) The electric winches do sell well to end customers, so I have them on some remote applications. But adding a high-juice-draw device like the winch adds more stuff to the system...which adds more weight and complexity. Yeah...it sells well, but for the remote systems that I rent out and service myself, using a hand winch keeps the system simpler and seemingly lower maintenance.
-
Yes, you can totally do that and run switches in line. Cable For those longer 150' cable runs, use some quality cable (I like all copper instead of the CCA stuff). Cat5e or Cat6 should be just fine. Switch vs Hub Switch The nature of a switch minimizes unnecessary network traffic. Type of switch For simple 3 cameras, a Fast Ethernet (10/100) switch is fine. However, these days, I prefer Gigabit (1000Mbps)...but it's more effective if you've switched the rest of your network over to Gigabit. Brand of switch D-Link, Cisco, Linksis, Netgear, TP-Link, Trendnet, Asus, Buffalo I've been fine with all those brands.

Help with selecting system type based on limited internet
zr1 replied to lukeduke02's topic in System Design
For recording, the internet speed doesn't matter. The cameras and NVR can record at their highest settings if you want on the Local Area Network (LAN). Whether the Cat5e/6 wire from the camera goes back to the NVR directly or you have switches on your LAN (simply use Gigabit switches and you'll have plenty of LAN bandwidth). For the internet part of it... Most systems already have a function called a substream to send a much-lower bandwidth video portion to the internet connection. Whether by remoting in from another computer or via smartphone/tablet. So even a lowly 3G-cellular connection could handle spot-checking or remote monitoring. Even a low-512Kbps DSL would be just fine for that. And if you wanted to (from remote) you could simply click on the Full-Stream button/option to give you the high-detailed version, it just lowers the frame rate. (Some newer systems have 3-tiers of full-stream/sub-stream/mobile-device stream...and you can customize all those bandwidth numbers on many systems tailored to your internet connection. Also remotely, you could download the recorded video to you whenever you wanted, the internet speed would affect that. But for local recording? The internet speed doesn't matter. And I'd still go IP cameras/NVR whenever I could on a new system. I have solar-powered systems on cellular that record fantastic locally and I simply spot-check them as needed. I have some solar-powered systems way out in the middle of nowhere that record away even where there's no internet/cell service. And for those, I gotta drive out there to get the recording (what we used to call "sneaker-net" back in the day...hehe) -
High-Def Good choice on that. When I'm doing a new-install, I don't bother with coax/High-Def analog (TVI, CVI, AHD, SDI, etc.) and I go straight to IP systems using Cat5e/6 wiring. IP The cams can be 1 megapixel (MP), 2 (which is about 1080P like Blu-ray), 3, 4, 5, 8....it goes way up..as does the price. The sweet spot for pricing was in the 3MP range last year, but lately, the 4MP IP cams have come down in price and seem to be the best bang for the buck. IP NVR The NVR will have to be able to record at whatever the cams are giving. A midrange Hikvision NVR will take 5MP recordings or lower. Throughput - Each cam is transmitting an amount of data (such as the above-mentioned 2048kbps...most cams are adjustable too to balance detail vs data usage). A mid-level Hikvision NVR might handle 50Mbps...so more than enough. But a no-name-cheap-NVR might only handle 10Mbps...so hooking up 8 cams to the el-cheapo model might bog down the recordings a bit. Agreed, they're quite good. Agreed. Most of my small business installs like to have about a month-worth of storage. Cams This will be specific to where they need to be. Ball/turret cams Dome cams bullet cams lens (telephoto vs wide angle) weather resistant vandal resistant Brand A/B mixing We do have a common protocol known as ONVIF...it does work. But it isn't perfect. When I'm doing a ground-up install, I simply stay with one brand and it avoids the Brand A/B mixing question.

Catch * hidden cams * sometimes you already suspect something bad, but going public with your suspicion might be bad for you (company wanting to fire an employee, but without proof might face a lawsuit, etc.), so a hidden cam helps you get the information to act (or not act) * you're willing to risk using a bad thing happening to catch the act This is more common with employers that suspect employees doing things over the long term. Such as a business where the employees were taking company materials, loading it up on company trucks, and going out and doing their own work for customers and keeping all the money. In this case, the business was willing to risk losing a few thousand dollars of materials in order to figure it out, find which employees were doing it, and try to reach out to the customers they were losing. In the long run, the few thousand dollars of materials (that was pretty much used as bait) they lost was offset by the tens-of-thousands they brought back into the business. Deter * Cams out in the open * You don't want to risk something bad happening +1 on that

Compatibility of 3rd party IP cameras
zr1 replied to Retrac11's topic in IP/Megapixel Cameras and Software Solutions
The closest compatibility we have is the ONVIF protocol. It does well. But it's not perfect. Most all the time, the ONVIF devices I have play well together. When I have incompatibilities, it's usually with some semi-advanced feature not working, but most all the time, I'm at least getting an image and recording. However, when I'm doing a brand new system for a customer from the ground up, it's not worth the time (whether 1 in a 100 or whatever) in a business environment, so in those cases, I don't mix Brands and simply go with a single brand. -
I had some giant 8' boxes I brought home for my stepson (age 11) to build a fort. Of course...I wired up a little security camera (outsiede the heavy-duty box) to a 7" monitor (inside the box). He and his friends thought it was way cool to have a fort with a security system. The camera is outside, and it's an indoor ball/turret camera. Nothing special, just a cheapo analog camera I never used. It's rained a couple of times (but not super heavy) and the camera's still going. Water will kill it at some point though. I'm surprised it lasted these past two months. I bet the coming summer Monsoons will render it toast.

why should i go with 3MP&5MP ,when NVR's support 1080P Res.
zr1 replied to Subhakar's topic in IP/Megapixel Cameras and Software Solutions
It goes to the goal of a security camera which is to capture what happened. NVRs do vary, but take something such as the Hikvision DS-7604NI-SE/P. It can record up to a 5 megapixel resolution. So the 3MP, 4MP, or 5MP camera gets fully recorded just fine. Now the playback output is 1080P. Which lines up with the majority of monitors/TVs out there in 2016 being 1080P. But the recording is still in 5MP (or whatever the camera recorded it as). So on playback, if a person wants to see the higher resolution, they can zoom in and see it. Just like an iPhone or Android smart phone where the photos are captured in 8MP or higher, but the screen is only around 1080P, so zooming in on the photo afterward to see whatever detail. Same deal with the high-MP NVRs, the recording still has the detailed resolution to zoom in on when needed. NVRs with higher playback resolution are appearing. There's the Hikvision DS-7608NI-S that can playback up to 2560x1920. And a few manufacturers at the Vegas security show a couple weeks ago were showing NVRs (and cams) with 4K resolution (about 8.3MP) to line up with the 4K budding trend with TVs. How many years will we all have 88" 4K monitors in our bathrooms? 5 years? 12 years? Maybe by then, 27MP monitors will be coming out? -
IP can run over coax, but pricing is a factor. It involves using a device at each end of the coax. One by the camera and one by the NVR...for each coax. A pair of devices are about $100 on the low end, but there's device-pairs that run $200-300. For a business that has invested thousands of dollars into their coax installation (and a new Cat5e install would run thousands), IP over coax can be a dollar-saver. But for a residential situation for a do-it-yourselfer on the weekend, that's typically more than the average budget of a 3-bedroom house. So it leaves 2 other options: 1) pull out the coax and put in Cat5e/6 cable - not the most expensive, but significant time. 2) Go to one of the HD-over-coax solutions such as TVI, CVI, AHD, SDI, etc. These top about at about 1080P (about 2 megapixel-ish), so you're not getting those 3 or 4 megapixel images, but it is definitely much better than regular analog. Whichever one you go with (TVI, CVI, AHD, SDI, etc.) it means sticking with that specific type...so if you went SDI and a year or two a cam goes out, then you go get an SDI cam. Personally, SDI seems to have the slightly better imaging to me...slightly. But for my HD-over-analog customers, I'm most always using TVI for one of these reasons: * TVI allows for very long cable runs (not an issue for an average residential/house situation) * TVI is open source, so a lot of companies are on that bandwagon (unlike...say...CVI)..easy-peasy replacements * TVI is real low cost these days

With a dynamic IP, the camera just takes whatever IP address the router is giving it. That IP address will typically stay until the router and/or camera is rebooted. Locating the camera's IP address can be done a couple of ways. 1) Use the router * log into router * look for something such as "Client Table" or "Client List" which should show all the devices that the router is talking to. Some routers are better at this than others and some routers have a wireless list and a wired list. Many households with smartphones and such probably have 5-12 IP addresses on the list...one of them will be the camera then you can log back into it. 2) Search the network using software Some camera companies offer a free "camera scanning tool" which is really just a simplified local network scan. It'll locate the camera in a jiffy. 2b) Use generic network scanning software This will list out all the devices on your network with their IP addresses (kind of like option 1) above). Google for a free "network scanner" app. There's a ton for the PC, but also some for smartphones. I use the "Ping Tools" app for my Android phone in case I lost a camera IP while on an install. 3) Reset the camera to factory settings Not all cameras have this, but some do. Such as a little recessed button to hold down for 5 seconds or something.

Need help setting up a last minute CCTV system for my home
zr1 replied to riley3245's topic in System Design
If I'm understanding the options for the outside cameras: a) wireless & battery powered b) cut into the recent 2nd floor drywall and run Cat5 cable Option B is much less hassle. In 2016, wireless is still...not...there...yet. We like our security cameras to run much higher than 99.9% of the time. Because at 99.9%, they will disconnect once a week where you'll have to manually get them reconnected again. My customers would be calling me (all sorts of names ) if their security cameras went offline even once a month. Batteries Security cameras aren't giant wattage-hogs, but they do run 24/7. It might be $30 in batteries for a single camera to run for 1 day. Then you gotta either: * recharge the battery * replace the battery Plus there's battery care so the battery doesn't get wonky and won't hold a charge, etc. +1 on running a wire to the outdoor cameras then re-patching the drywall. A good installer works with that kind of thing anyway leaving no trace afterward. -
Quick Question on IP Hardware Setup before I install Cat 6
zr1 replied to Postmon's topic in System Design
I'm not fully understanding your text-based layout. Are you referring to something such as this? For PC #1 (one that is on your local network) It'll connect to the NVR easy-peasy just using the local IP address of the NVR (such as 192.168.1.108..or whatever it has been assigned on the local network). for PC #2 (outside the local network) It can connect if there's a mechanism for it to pass through the router, such as a port-forward setting on the router. -
Thanks for the advise How did you harden the NVR/DVR? Do you you use a NAS, NVR DVR? What model? Steel boxes, sometimes welded up by local companies, other times, like on construction sites, the "job box" style similar to these (different sizes have been used): http://www.homedepot.com/p/Jobsite-36-in-Long-Heavy-Duty-Steel-Chest-in-Brown-Tan-635990/203777537 The box does cut down on the cellular connection, so sometimes we have a little antenna on top. The box has 600-1000lbs of batteries in it with no wheels, so not easy to go carting off. But other layers include a fence around the job box...lots of signage, sometimes it says the video is recorded remotely via cellular (and sometimes that sign might get placed even if the DVR/NVR is recording locally...oops ). I'll mention the blinking red/blue LEDs again...they've been quite effective in some areas. This isn't the one...but looks similar with a magnetic mount http://www.amazon.com/B1L-NON-FLASHING-STEADY--WARNING-BEACON/dp/B00S466IQC/ Ya gotta test out a bunch of different flashing LED lights to find one that meets your needs. Also cameras that face each other making for no blind spots. DVRs have varied over the years, even going back to analog days. Lately, some of the LTS 8ch "Platinum" versions of Hikvisions have been the prime choice. They do well in the Arizona heat...you'll have to ask others about colder climates. A few times...we started just for kicks...but it kinda worked...we stuck a wee little cheapo "wifi cam" in the construction trailer office or under an eave if it wasn't going to rain (the things aren't waterproof) and connected them via wifi to the NVR. Not a hidden cam...but so stinkin' small they went unnoticed. They run on a 5v USB cable...so we simply used a little $30 USB battery that people use to charge their smartphones and got enough juice to run through the night. It's not a robust solution, but started as something cute, and still stick one on a site now and again as they're so small they don't get noticed. One could do the same thing with a "game cam" that hunters use to track deer before hunting season.
-
Enclosure I do remote construction sites for cam setups (with lights too). The enclosures are typically those tool "job box" style enclosures that can be locked up and look like they belong on a job site. But pricier than a plastic enclosure. What's the purpose of the enclosure? * keeping rain/moisture/dew out of your setup? * hiding from curious eyes? * security? * other concerns? Once you know those goals, then the enclosure solution becomes more apparent. A good outdoor cam is weatherproof, so then you're just talking...the battery itself? maybe a plastic marine battery enclosure used on boats? Juice for the Cam It's going to be math to calculate: * juice usage by the cams and/or NVR/DVR (an IP cam recording to an SD card might save you some juice usage as it doesn't sound like you need a multi-cam setuip) * juice usage of the cams if they go to IR (IR takes up more juice...it should be on the cam's spec sheet...if the area is lit..then get a cam without IR or turn off the IR to save juice) * juice supply capacity from the battery (also, you wouldn't calculate down to 0% for the battery...it depends on the type of battery. Some batts can only take so many trips to 0% before they're toast) There are many online calculators to figure out the math for battery usage (often on solar or prepper sites). Replenishing the Batt Do you cart off the batt every 5 days to go plug in? Take a generator out to it? Solar (doable...but yeah...more $$$ and more...complexity)
-
I do remote installs where there's no power (construction sites, etc.), and use 3 of the 250ah batts in parallel for a 12v system. But it's the lights that take most of the juice. If it was just cams, I could get by with probably 1 batt....it's just a matter of doing the math of the juice-usage...there's calculators on the net. Of course, ya gotta charge the batts periodically somehow...I've been using solar (another pricey set of variables to consider). But on the batt side, they each weigh about 175lbs, and they aren't cheap. LiON batts are lighter...but much pricier. The AGMs work well, but had some longevity issues in the Arizona heat...going to gel has helped a bunch.
-
+1 to the above Fast Ethernet (100 Mbps) works great for that number of cams for an average resolution. Check out some of the "bandwidth calculators" on a Google search. If the network is shared with...say...an office network, then I've either used Gigabit (1000 Mbps) switches for not a lot more...or I've simply run the cables back to the NVR and kept the camera network separate from the office/home network.
-
* Hide * Harden * Remote This applies to either the DVR/NVR, or the connection (or both). It takes creativity to apply any of those 3 above, and there's some great creativity above. I've done each of the above (as well as combinations) for some interesting installs. Sometimes at construction sites, it's a lot of hardening combined with really obvious signage and some obvious (and hard to get to) cams and a cellular connection on top. But each situation can mean going back to the creativity side. For example, at one location, the thieves did knock the high-up cams out of their angle and tried to steal the hardened DVR...but were unsuccessful. And since the cams didn't have a blind spot, the thieves were caught on their approach. For some really bad areas of my installs, we have some blinking LEDs through the night along with motion lights. The cams don't need the motion lights, but I've seen on cam quite a bit when the approaching person gets lit up by a motion light, they turn tail. It's not a catch-all. Not even close. It's layers.
-
Yup...that's not a thermal camera. It's a nice regular cam with infrared, so it can see at night, but yeah, not through hedges. But not thermal. That cam runs about $100-200 depending on the internals of getting a better resolution (high-def matching or a bit better than Blu-Ray). Thermal cams run a good $10,000 for a very mediocre resolution (use them for some work contracts...and they're pretty cool).
