You can't use a RJ45 splitter for networking, basically they just parallel the wires from 1 to 2. To connect 3 devices together, you'll have to use a switch/hub. Basically you got the point. But it'll not be as easy as using it the way manufacturer envision you to use it.

Glad that some of you bother to read what I actually wrote instead of just selectively seeing what you want to see. Just back from Holiday !

But if a person goes up a ladder and uses the network cable and connects to the network with a laptop that has not been on the network and DHCP is off on the NVR then that is not going to work. So I will stand by my first post. As long as your network is secure there is no problem having an IP camera outdoors. As I mentioned, for most of the consumer end and even enterprises level NVR, there's no way to secure the network by using the default NVR's LAN port. You'll need to add in smart switches to harden the network. That'll need to work hand in hand with the IP cameras as well and most IP cameras doesn't support the extra layers of authentications as well. Now try this. Switch off your NVR's DHCP. Connect your laptop to the NVR, set it to a any private ip, e.g. 192.168.1.10 or 10.0.0.100. Do a scan using the discovery tool of the manufacturer. Or you could use some other network tools to scan the network. You'll be able to detect the IP addresses of the NVR and the Cameras. Now, if the IP address of the detected NVR is 192.168.0.1, change your Laptop's IP to 192.168.0.10, Gateway to 192.168.0.1, Subnetmask 255.255.255.0, DNS set it to 8.8.8.8 , you should be able to surf the net and also access the network the NVR is connected to. Don't have to take my words for it. Try it and see how by switching off DHCP only makes it harder, but doesn't make it secure. As for staying on ladder, just hook up a WAP to that Lan cable connected to the IP Camera, you can even use one that has 2 LAP Part with POE and POE bypass. Just need a couple of mins on the ladder to insert the WAP in between the IP Camera and the Network cable, and now all you need to do is be within range of that WAP to do the deed. You don't even have to be within sight.

You might want to revisit the K.I.S.S. principle. Complicated setup means the level of technical skill to troubleshoot or reinstall it at the next site will be hard. Sometimes the simplest system works best.

Very few cameras. Probably two, maximum. Yes, I'd like for them to record to something, but again, not 24/7. From what I understand you can program the cameras to record on motion, which would be handy. So there will be a DVR of some sorts. Yup, there's internet access, the power source is a house on the property that is fully wired and has all the necessary hookups. So it would run back there. The idea being I would then be able to view the feeds anytime from my iPad or computer or something. What do you think? for it to work would they essentially have to be "on" round the clock and drawing energy as a result? The system doesn't draw much power. If power is really an issues, use SSD for the DVR. The harddisk consume bulk of the power in most system. You can record on motion, however i would recommend that you set it to continuously record at very low quality and switch to higher quality when it detects motion. Do note that unless you add in outdoor motion sensor, the system will be doing Video Motion. This means that the system will analyse the images, and if enough chances occurs in the detection zone, it will trigger the event. Trees swaying will also be detected as motion. You can set the sensitivity lower, but that means you might miss the thing you want to record. There are better system that are able to minimize these false alert, but with more accuracy it also comes at a much higher price. So it comes down to your budget. Alternatively, some system allows you to take snapshots at interval. e.g. 1 pic every 5 mins, and email them to you, or store them on a SD Card. So it really depends on what you want. Netgear have a wireless system and they claimed the cameras can operate with battery wirelessly for months. (Fine Print : for few mins of viewing/recording per day). If you are able to extend your wireless network to the location where your cameras will be, that might also be a possible solution. https://www.arlo.com/en-us/ "The NETGEAR Arlo Wire-Free camera battery life lasts 4-6 months with normal usage and can be extended for optimal usage by following key settings and tips. They offer the best battery life when set up to record when they detect motion. " "Normal usage is defined as 4 minutes of viewing or recording per day with the Arlo Wire-Free camera in the Optimized setting. " https://community.netgear.com/t5/Arlo-Knowledge-Base/What-is-the-battery-life-for-NETGEAR-Arlo-wireless-cameras-and/ta-p/291 I won't recommend it though if you are looking for a actual CCTV system. 4 Mins a day.

Cheapest way to do it. Get a dashboard cam, set it up for motion sensor recording. Install it with a view of your DVR or your main door and conceal it. If you suspect any intrusion when you where gone, check the recording of the dashboard cam when you are back.

From your log, it seems like this is could be what the intruder did. After coming into your house, e.g. 5.23pm and exit out at 5.33, the intruder changed the time of your DVR so that it become 5.23pm again, in effectively overwriting the 10 mins of recording when he's present in the house. That might be how he cover his track. But then again, I'm not familiar with how this system log down events and what exactly each event specific, it could be just the timing chip is lousy and the system keep updating the time from NTP server. It's NOT normal to have so much time change event in your DVR. Either someone keep messing around with the time of your system, or your system have a really lousy timing cheap that cannot keep accurate time and keep getting NTP update to keep the time accurate. I've seen that in some cheap system or some batch of branded DVR that happens to use a batch of bad timing chip. It's also not normal to have Disk Over/Shutdown/Reboot happening. The word "Abnormal" at no. 70 should give you some indication. Either there is something wrong with the hardware of this system, or the configuration is mess up, or someone is messing around with this system.

By right, if the NAS support CIF/NFS, it should work with the newer HIKVISION DVR. Some of them required a bit of trial and error before you are able to get it to work. The DVR will FORMAT the whole partition it is assigned to for recording to it's own structure. So in order for you to use your NAS as a storage device and also concurrently use it as an extended drive for your DVR, you'll have to create multiple partition on it and mapped accordingly. More tinkering. Some NAS doesn't allow you to split a single drive into multiple partition. Only assigned different partition to different drive in the NAS. So for those if you are using a single drive, you can either use it for the DVR or for your PC. Not both. It's not a straight forward process though from my experience. No help's to be expected from the manufacturer unless you are using their NAS and their DVR from my experience.

Avoid P2P if possible. Use it only if you really cannot get all other methods to work.

Without any brand/models, I don't think anyone can advise you. Generally speaking, all NVR's password can be changed. Depends on which brand/models you are using, the UI will look different. Most of them would be in Configuration->Account Management->Users.

You don't need CMS software to do that. The Camera can managed the NAS to do recording without any CMS or computer running. But limitation is as what I said. 1 partition per camera. If you are talking about using the CMS to record to a drive mapped to the NAS, your CMS software have to be running, which means your computer on. Otherwise, you can also set the cameras to record and ftp to the NAS, using the NAS as a ftp server. However, i don't really recommend that as it makes management hard. You can't use the search/playback function of the cameras to search for the period that you want. You'll have to manually delete the files when the NAS is full. That among others.

My Exact Words.... I didn't say IP is crap. IP give better quality than Analogue at the same resolution. 720P IP give better quality than 720P HD-TVI/SDI from the same brand. But as I said, unless you are technical and familar with IP Network setup, avoid it as installing Plug and Play IP Cameras with default setting is a security risk especially if any cameras are located outside where intruders can gain physical access to the network point. And yes I agree with you. That brand has been producing substandard quality products these few years. Lots of units that fail, power board burnt and melted, cameras going losing color less than 1 year, etc. I avoid them nowadays. DHCP is not a secure way to set up your network. Also your example is crap ..... Do people connect a PC to there NVR camera port ?? Answer is no ...... Also that is local connection. Try turning off the DHCP feature of the NVR. The Plug and Play function will no longer works. Now, refer to my original words. Does disabling the DHCP makes it totally secure for NVR ? Nope. Just using the software, e.g. Videoviewer from AVTECH, SADP from HIKVISION, etc you'll be able to scan the network and find out what subnet the NVR is configured for. This is using discovery tools from the manufacturer, not even "hacking" tools. You'll be able to manually set up your laptop to the same subnet and access the network. Most NVR doesn't have MAC Filtering to restrict access from that unknown mac address your laptop present to the network. Even with Mac Address, you could clone the MAC address of the IP camera you removed and you'll have access as well. And most NVR doesn't have other form of secure authentication to restrict access to that network. Even if they have, Most IP Cameras also doesn't support it. Not these brand at least. I thought I was pretty clear on this. External camera in this case, refers to a camera installed OUTSIDE your house where intruders can easily have physical access to the camera without breaking into the interior of your house/office/warehouse, etc. That Camera would have a Network Cable connected directly to the LAN port of your NVR. It'll allow a physical entry point to your NVR. It's like pulling a network cable from your internet router and placing it outside your house. Anyone can plug a device in to that network cable and gain access to your network. Being on the same network would allow for 1. Scan the network for any available PLUG AND PLAY camera with default password, enabling the intruder to access all connected PLUG AND PLAY Cameras feed, including other cameras installed inside the property. Users have to manually configure all cameras to non-factory login in order to present higher restriction to any intruders that gain access to the LAN port of their NVR. 2. If the NVR is connected to your internal home/office network, gain access to THAT network as well. I didn't say avoid IP system. I said avoid IP system IF the installer is not equipped with the technical knowledge on how to harden the security of the cameras. Or rather, my exact words are DVR and NVR is different. Gaining access to a analogue camera's coaxial feed will only gain you access to THAT particular cameras. Gaining access to a IP camera network point that's not sufficiently secured will enable you to gain access to the network and the external network that system is connected to. Not to mentioned all Cameras feed as well if the IP Cameras are not properly configured. Do take note that there is for most NVR in the consumer market, there's no way to prevent access to the internet router that the NVR is connected to. You can only change the default password of all devices to present a harder target for intruders to attempt to acces. I didn't say avoid IP. My exact words are Like someone who try to setup their internet router, but not knowledgeable to know that they have to secure their WIFI with a password, it's best to engage someone with the technical expertise to do it. Yes, they will get the router up and running together with wifi. But unknowingly, they allow everyone in the vicinity access to their internet and their internal network. I seriously thought anyone who know the simple structure of how a computer network works would see the vulnerability of such a design. I'm sorry if that offended you. Not meaning to be personal on that. I just think you didn't take the time to read my post properly and jump in to defend IP Based System irregardless of the security risk they presented if installed by people without sufficient technical skill. I am not against IP System and I used quite a large numbers of them. It's just people are installing Plug and Play cameras in their default settings without knowing the risks involved. Just try out what I suggest, don't take my words for it. Connect a NVR to your internet router which is connected to the internet. Plug in your laptop to the LAN port of the NVR. Try surfing the net and also try gaining access to configuration of your router. Most likely you'll be able to do that. I tried that with a few brands, all works.

Wow lets answer your reply again ..... But this time YOU forget about network. Poe NVR to camera is the same as camera to dvr .... No security risk at all. As I mentioned in my other post. Don't take my words for it. Plug in your laptop to one of the POE switch on your NVR which is connected to your home/office network. You'll be able to access all network that your NVR is connected to. The NVR is essentially a router. Most NVR doesn't have Mac filtering (even that can be defeat easily by MAC Cloning), and they don't have authentication built in for devices to access from the LAN port of the WAN to the LAN. example, if your router is 192.168.1.1, your NVR is connected to your router. Your NVR's internal IP range is 10.0.0.XXX. Now, you connect your laptop to your NVR's POE port, your NVR DHCP server will assigned it 10.0.0.10 (for example). Try opening your browser, type in 192.168.1.1 on your browser, you'll see your router's configuration page. If you got NAS, etc connected to the same network, the laptop will be able to access all as well. I assumed you are not IT trained, else you would had realised it long ago.

Depends on how you power your cameras. If it's POE, then yes. If it's not, then you don't have to get POE Switch. The switch is connected to the LAN port of both DVR. It's not connected to your router. Basically it puts both the NVR on the same network so that the IP camera can stream to both NVR. NVR are defaulted as a DHCP server. This means IP Cameras connected to their POE Switch or their LAN network will be assigned IP automatically. Putting a switch to bridge them to the same network means now that you have 2 DHCP server on the same network. That's highly not recommended as it'll cause confusion to the devices on which server to get IP from, etc. Also, both NVR will be most likely set to the same default LAN IP. You'll need to manually change 1 to another IP so that there's no IP conflict. The Camera IP matters. Because now you are connecting multiple cameras to the same LAN as your both NVR. The NVRwill detect all cameras connected to the LAN. you'll need to seperate which NVR will see which camera according to their IP. Not so easy. You'll have to have some basic network knowledge to know how to get it set up.

Yup. From Singapore.

Bosch MIC7000 Supports ONVIF. So in theory you could use any ONVIF supported NVR to do recording and also connect a monitor to view. It should also comes with a video client software that allows you to do recording on your PC as well. The Decoder from Bosch videojetdecoder3000 doesn't come with a HD-SDI output. Only HDMI and BNC(SD). You could just get a HDMI to HD-SDI convertor such as this to convert the signal to HD-SDI and input to your recording system. http://www.sct.com.tw/SDI02.html You could also source a 3rd party ONVIF decorder with a HD-SDI output as well, but do note my experience with ONVIF is not all ONVIF are the same. You might need some tinkering to get it working, or not at all, or won't even be able to get it to work or work at full feature that the camera is capable of. https://www.google.com.sg/search?q=ONVIF+Decoder+with+HD-SDI+output I think you should have some compelling reason why you want to convert to HD-SDI input for your own recording system, otherwise, recording it directly using the client software should be the easiest.

Swicher - Switch between cameras at interval. you'll miss out action when it switch to other cameras. Multiplxer - Allows combining of multiple cameras feed to the VCR. Cheap will just do multiple display and record the same display to the VCR. You'll play back the same display, so each camera occupied only part of the screen. more camera, smaller. Live multiplexing was more expensive, so that's why the older one normally have different FPS. Cheap one less fps. Better one live. Better one will cycle through the cameras and store each one with whole frame. When you playback, the VCR output will goes through the multiplexer again to combine everything and also allow zooming in to each camera to view full screen, etc. However, due to the recording method, you can never achieve live FPS. It's normally only ard 25fps (or 30fps for NTSC) divided by the number of cameras you have. 16 Channels Multiplexer can only record at ard 1.5fps. VCR are time lapsed. You can use a 240mins tape to record for 24 hours, or even up to 1 week on some models if i remember correctly. They'll turn the tape slower to record. Quality is sacrificed for the length of recording, like how we set the compression quality on DVR nowadays. You got to change tape regularly and have multiple tapes to cycle through.

Sorry, never tried matching like this. I normally advice using the same brand of cameras and NVR and don't trust the ONVIF stuff. It takes a lot more effort to set that up and does not have a 100% compatible rate even if they stated ONVIF. From what I know, HIKVISION encrypted stream is only meant for their EZVIZ P2P connection. Not too sure if it is meant for their direct connection.

It's NOT the same as a DVR. The DVR's Video In Port only allows video signal in. No network traffic. Basically the NVR will act as a Router. The LAN IP port you are connecting the cameras to are like the LAN Port of your Router. The WAN Port of the NVR will act like the WAN port of the Router. Connecting the NVR to your network basically extend your internet to whichever device that is connected to the LAN port of the NVR. Any Network Device connected to that External Network Cable will be able to get on your NVR network, which is in turn routed to your home network. Most NVR internal router function is not so advance to do MAC Filtering (You can also bypass that by cloning the mac address of the camera you unplugged), or other form of advance authentication. As the NVR resides behind your router and within your internal network, it'll have access to your internal network. You could harden that up easily by placing another router(B) behind the initial router(A) that connects your home network to the internet. Connect the NVR to router(A) and your home network to router(B). Router B will block all unauthorized connection if someone tries to gain access to your home network through your NVR. However, that will NOT protect any unauthorized access to any Plug and Play IP Cameras that had been connected to the same NVR. Using Default login, the attacker would be able to gain access to all your camera feeds, including internal camera feed if you happens to connect those to the same NVR as well. You'll need to manually lock down each and every IP cameras with password. But that means a lot of configuration and it's no longer Plug and Play. You don't have to take my words for it. Connect the WAN port of your NVR to your home network. Connect your laptop to the LAN port of your NVR. If you leave the NVR at default with DHCP on, etc, you'll be able to surf the internet from your home network and also access any network storage/printer/etc in your home network. Even without DHCP, you can manually set the network setting of your laptop and do the same. Try it.

Yes. Some Brand/Model of IP cameras support that. e.g. HIKVISION. They do edge recording as well (some models). i.e. you put in a SD Card, and you configure a NAS for it. It'll record to the SD Card and also to the NAS. If the NAS is offline, the SD Card acts as a buffer and when it comes back online, it'll dump the recording the NAS missed from the SD Card back to the NAS. However, do note that the models I tried required from HIKVISION required the NAS to be solely assigned for this purposed. They'll format and wipe the NAS. So you'll have to get a NAS for this purpose only. You could tinker with it setting up, setting up multi partition so that 1 is use for the IP Camera, the others use for other purpose or other IP Cameras. This you'll have to figure out. I did get one working with 3 partition and 3 cameras streaming to it previously, but i remember it's not a straight forward process. Also, With 1 harddisk segmented to multiple area and the multiple IP cameras continuously streaming forcing the write head to jump from sector to sector to write consistently, I'm not too sure how good it is for the HDD. And not all brand/model of NAS is supported. If you ask them, they'll tell u to get their brand of NAS which is a lot more expensive than the one you could get normally, e.g. DLINK, etc. I've tried a couple of DLINK NAS, it works. I've also flush a old DLINK nas to ALT-F firmware. It works as well.

Unless you are very technical and familar with IP Network setup, I would advise avoiding IP Cameras with NVR if any of the cameras are located outside your house. Especially those Plug and Play IP Cameras. They would provide an entry point to your home network. I'd done testing with multiple brands of system and cameras and they have multiple vulnerabilities if not properly configured or proper additional network switch added in. For Plug and Play IP Cameras, it would be possible to gain access to all cameras feed without knowing the password. For DVR with Switches built in and connected to your home network, it'll be possible to gain access to your home network. If you have unsecure drives/system connected to the network, hackers would be able to copy all files. Use Analogue Cameras with Balun instead. You'll be able to utilise your existing UTP cabling.

Check if the DVR support coaxial communication between the camera and the DVR. If it does, you are best using back the same brand of ptz camera that support coaxial communication. Don't have to run rs485 cable. Otherwise, ensure that your DVR have RS-485 port for ptz control. Not all DVR have RS-485 communication port and support ptz control. If your DVR doesn't, that means it cannot control the ptz camera. You'll have to change your DVR if you want ptz control. Check out the DVR manual to see which protocol it support. You can always switch to pelco-d protocol for both cameras and dvr if they are from different brand and doesn't have any other compatible protocol. Different brand have their own different protocol, which gave them additional functions. That's why as far as possible, try using same brand. It'll take some tinkering if it's your first ptz camera to get everything right. If possible, don't install the camera first. Set it up beside your DVR, connect everything up and set up the protocol, id and make sure it works before installing. Most ptz cameras are configured using DIP switch in the cameras to set the protocol and channel. Most unbranded default to Pelco-D and channel 1. Others default to their own brand, e.g. hikvision, samsung, etc. If you only have 1 ptz, you might not need to do any configuration. Otherwise, you'll need to set the other cameras to different channels. Some requires an additional controller to be purchased to be connected to the camera to configure it. Some require a ptz controller to set the channels. That's why i suggest putting all cameras you are going to install next to the dvr, cable them up as if you are installing them, and get all configuration right before mounting them up.

Identify if it's your network viewing problem or the cameras are not properly connected to the nvr. Connect a monitor to AVH316 and see if all images appear. If they don't, configure it properly for it to appear. Easiest way is to factory reset everything and let it auto detect and plug and play. IMHO, AVH316/AVH306 is one of the most problematic NVR Models i ever encountered. Had problem maintaining a stable connection with the cameras (also AVTECH), requiring reset every now and then to get back connection to the cameras, etc. Firmware updated countless time without resolving issues, little or not support from manufacturer to resolve the issues. Replace it if you got the chance.

And yes. It's definitely a LOT cheaper than milestone. Just realize you are comparing to milestone. And like what ilk said, the cameras optimal installation location is right overhead looking down. This prevent people in front from blocking images of people behind. The CCTV camera would not not achieve the usual aim of security function as it is basically meant to look down at people's head and count them. They won't capture face, etc.

Why would you want to use a CCTV camera for head counting ? You'll get the figures, but you still need software backend for presenting the data in graphical or trending or statistical form. Combining multiple cameras data in same store or different stores needs quite a bit of integration work as well. You might be better of using purposed build system to do headcounting, e.g. http://www.retailcam.info. Price are comparable to people counting cctv cameras, or even cheaper in most case. It's able to do headcounting of a 12m doorway mounted at 3.5m height with accuracy of at least 95% to 98%. Apart from that, it also have wifi signal tracking built in. It's also able to track outside traffic, e.g. people passing by outside out of view of the cameras without turning in, customer dwell time (how long customer stay in the shop), customers return rates (how often the customer return), cross shopping (if the customer patronized other outlets), sales conversion (required integration with the pos), etc. Single integrated system with a cloud portal to view all data collected in dashboard format and downloadable in csv format. I gave up using CCTV cameras for headcounting as there's a lot of integration work at the backend to do to present the data to users. Also, most of the cheap cameras that do "headcounting" basically do line crossing counting instead. Multiple people crossing the target area will just count as 1. Overtime, it grossly undercount.
