who said u need 4 switches in each direction to reach ur target u will only need ONE fibre cable connected to the other switch

I understand plenty in regards how IP cameras work. Changing passwords on an IP camera is not difficult for me, all it takes is logging into the camera's HTTP(S) configuration page and performing the password change, but the issue here is that when you are going to do a 32 or even a 128 IP camera installation, having to change the password of each IP cameras one by one becomes a tedious and laborious task. With an TVI DVR, you only have to change the password of the DVR and only once, thats it. Plenty of time saved. Who cares about not being able to save stuff directly to the camera via a (Micro) SD card. I prefer things completely centralized and if you justify saving stuff directly off an IP camera for redundant purposes in case if the hard drive of an NVR were to fail, you can create a much better redundant approach such as configuring another or a few computers with a VMS installed and configured to save footage on these computers and then strategically place these computers that will keep a clone of everything saved on the NVR/DVR in a combination of onsite and offsite. Says who? There is always the risk of the power adapter of the DVR going bad or other issues and the DVR shuts down, This very same risk ALSO HOLDS TRUE FOR IP CAMERAS SETUPS, The power adapter that feeds into the PoE'd Network Switch can also go bad and if that happens all of your IP cameras goes offline, even if the NVR stays up and operational. I have installed almost 1,000 HiKVision TVI DVR's within the span of a few years and I have YET to see ONE of these DVR's fail, any failures always happens either on the DVR's power adapter, or the DVR's hard drive, things that are remediable without having to sell the customer a new DVR/change the DVR. Once again, all of your IP cameras gets their power from the PoE'd network switch and that PoE Network Switch gets its power from a power adapter, if that power adapter fails, all of your IP cameras goes offline, no question about that, there is no refuting that. Sure, you may say that not all of the IP cameras might lose power if there are a cluster of IP cameras on the far reaches of 500 feet that relies on a secondary PoE network switch that gets its power from another power adapter located on spot where that secondary network switch was installed, but if the long network cable is connected from that secondary network switch directly to the uplink of your primary PoE network switch and the power adapter failed on the primary network switch, it doesn't matter if the secondary network switch that is located 328 feet away to power those 500 feet away cluster of cameras remains operational, the network path between those IP cameras on the far reaches and your NVR/main router breaks the moment your primary/master PoE network switch lost its power source, unless you plugged in the secondary ethernet cable that goes to that far away switch directly to your customer's router instead of your PoE switch but most likely the customer would have occupied all of the ethernet ports of their router so you would have plugged in the cable to that gigabit PoE switch, the one where on my hypothetical example was the one who lost its power source. The same can also be said for other network switches you had to install, say 750 feet away, 1,000 feet away or so, any one of those can loose its power source locally affecting any cameras connected to those far away PoE network switch and all the other network switches of yours whose data unlink depends on the affected switch. So YES! There are cases where one power adapter failure that powered a PoE Network Switch can take out all of your IP cameras. Also, if you do a 8 IP camera installation and all the network cables are homerun to be back of the NVR's PoE network switch, the power adapter of the NVR can also fail, in such a case this will take out all of the IP cameras plus the NVR, if you had inserted SD cards to each one of those IP cameras as your redundancy measures those will also fail as all of the IP cameras would no longer be powered, so nothing would be recording in such an event. And what's the problem with this? I have seen IP cameras where all of the ethernet cables are homerunned to the back of the NVR, NVR's come in two modes, one with a PoE network switch already included on the back of the NVR and another where you are expected to bring your own PoE network switch, in either of the case you are required to homerun ethernet cables to either the back of the NVR or to the back of the Poe Network switch, you still have to homerun cables. With TVI you have to homerun coax to the back of the DVR and the Camera's location, I find that to be a great reliability feature. The less intermediaries you have to use between the Camera, Cable and the DVR, the more stable the connection is, the chances of future failure is reduced to a very low probability, if you use quality BNC heads you virtually dont have to worry about any point to point failures for literally ever. You are dealing with less equipment and less electronics. Here let me give your your worst case IP camera installation project: Scope of the project: NVR to be installed in the company's CCTV room located in the middle of the large premises. a few IP cameras to be installed over 1,000 feet to the north in relation to the location of the NVR A few IP cameras to be installed over 1,000 feet to the south in relation to the location of the NVR The same for west and east directions. In all four corners of the CCTV room you are required to run 1,000 feet of ethernet cable and because flimsy ethernet doesnt go farther than 328 feet without requiring network switches in between to give you another set of 328 feet to travel, you will need to daisy chain 4 network switches in each direction in order to reach the target areas where the owner wants you to install the cameras, so you will need 16 network switches, that 16 different power adapters that can go bad in anytime, chances are you are going to use the manufacturer's power adapters that came with each of your network switches, and manufacturers sometimes like to cheap out on the power adapters and you end up with a 500 mA 12 V DC power adapter for each network switch. Now fast forward 1 year after completion of the project, half of the power adapters of those 16 network switches fails, most if not all of the IP cameras are down depending on which network switch were to be affected by this. Customer is now calling you angrily complaining that in just one year most if not all of the cameras went offline. IF this was a TVI installation, all what you have to do is perform a long 1,000 feet run of a cable between the DVR and the TVI cameras, there is no further power requirements other than a SINGLE Power distribution box for which amperage I can control by buying the correct one for the load I want to run, I wont have to worry about spending extra money buying a higher amperage power adapter because the one that came with a network switch I deemed it to be too low for me to think it was going to keep on working reliably in the long run. And the other power adapter would be the DVR's power adapter. Just two power sources (DVR's power adapter + CCTV Power Distribution Box(es)) and the whole operation is powered for many years to come reliably, possibly I would have to return back to the site one every 2 to 5+ years to replace failed hard drives, but I wont have to return back to deal with some cameras having gone "offline". With an IP camera for a job of this magnitude, you have the issue that you cannot power all of the IP cameras centrally like you can with TVI cameras up to 1,000, well 1,500 feet now. The last network switch where all the cameras will be connected will be the PoE network switch and that requires a power adapter that is able to deliver many amperes in order to be able to drive all of the cameras behind that PoE switch, and because of the high amperage requirement you can't just run the power cable 1,000 feet to power it centrally, you will have to run a much bigger gauge copper cable and that would cost alot of money, specially since you are dealing with DC that on itself will require the AWG of the cable to be much lower. Sure you can run AC instead of DC and then use AC/DC converters or just a bridge rectifier with capacitor's if you prefer to build the AC/DC converter yourself. But the fact you had to run a low AWG copper cable at a length of 1,000 feet away to centrally power the PoE network switch located 1,000 feet away and chances are you would want to run multiple 1,000 cables to also centrally power all the other intermediaries (non PoE) network switches that wont require that much amperage will rapidly increase your investment, investment for which you might expect proper compensation from your customer unless you eat up the costs and agree to turn a much lesser profit. What a such a headache thinking about the possible expenditures in order to fulfill such a project using IP cameras instead of just TVI. So you see? TVI has its own set of benefits you must appreciate, you can perform a single cable run of up to 1,500 feet and dont have to deal with intermediaries. With HiKVision you are not locked into anything, Well I haven't checked and tested other software for mobile platforms, all what I know that when mobile is concerned, the IVMS-4500 app is one of the greatest thing there is, its super stable, its easy for customers to understand, specially those customers that only thinks Facebook is the internet and barely knows what "email" is. As far as PC is concerned, there is many options, you are not locked into IVMS-4200, you are use any VMS software you like and you can manually add all of your TVI cameras one by one as if they were "IP cameras" by using a special RTSP URL with your username and password included on the URL, then all of the cameras will show up on your VMS and you can take advantage of all the features your particular VMS has to offer you. So no, you are NOT locked into any particular one software. Partially that is true, because TVI IS cheaper than IP cameras for the same quality. I am not installing TVI exclusively because its cheaper and I just happen to make more money, I am installing TVI because I DEEM it more reliable, its my personal option, its what 35 years on the industry has taught me and my own observation and seeing others complain that their IP cameras keeps on going offline and that they have to constantly keep on restarting the IP cameras in order for them to appear again on the monitor. Now I dont know how cheap or how of a Chinese generic brand of such an IP camera is, but all what I know is that a great quality name brand HiKVision TVI camera can be had for $68 dollars at my supply house, a camera I know that is not going to fail me or make me look bad, a camera that is capable of capturing very clear and crisp enough videos to be able to read a license place of a vehicle a mere 40 feet away parked on a side walk where the camera is facing. To buy a similar camera from a name brand that is reliable enough to possibly not give the user uptime based issues I would have to spend about 2 to 6 times as much as what I currently spend on my motorized zoom TVI cameras. Um no way. Correction, it doesn't take me hours to post this, it takes me minutes, I type at 140 WPM, as part of me having signed up on this forum to help those asking for help, I am doing this as part of a challenge to further increase the amount of WPM I can type. I am trying to bump that number up to at least 160 WPM. So, in a sense my participation here is an attempt to further increase my rate I can type while I help others at the same time. Now, I dont know how fast you type, but if it would have taken you hours to type a reply like this one then I feel sorry for you, you will need to work on improving your keyboarding skills, there are many free websites out there that can further help in boost your WPM speed. I would not have any problems installing VMS and IP cameras, but I dont feel that the IP camera technology has met my expectations yet, I feel that its not stable enough, and that those ones (IP cameras) that are deemed Reliable Enough by the community are over priced and the equivalent TVI can be had for the fraction of the price. And sure, I am open to revisit IP cameras in the future, but it wont be now, not yet. When you enter a business store front, do you see them inform you that there are other alternatives? No, they sell you, or mention you only the things they currently stock. With all that said, when a customer comes to me asking for security via a CCTV installation project, I don't have to inform them about choices currently not available within my own business. --and no, I am skilled enough to install IP cameras if I want to, like I said before I have a CompTIA Network+ certification, I know all about networking, I have built networks, so I have a very strong networking foundation, installing IP cameras shouldn't be a problem for me since the very same ethernet cables that I have been crimping since way back before the concept of IP cameras existed, but I refuse to do so at the moment. I believe in CENTRALIZATION not in Decentralization, I believe in having just ONE server in the premises, not 32+ different servers being each one of those IP cameras in addition to the NVR that is also a server on its own. No, just ONE server is enough, the TVI DVR and all the other cameras doesn't need to have such functions. Its my own personal through out opinion to decide how I want to run my own business just like its your own personal through out opinion to device how you want to run your own business. I have perfectly valid points and there is nothing in the world that is going to convince me until my expectations in regards to IP cameras are met.

you have to 1st add ur workstation ip in the config client under workstation tab

i have the same problem with one of my clients but in his case only four videos open and the rest doesn't ,i tried using both pss and the smart pss no luck, the wired thing that all the videos load in the mobile application , the next step im gonna update the DVR's firmware and see the results. The DVR :2116 HE
