    I think you will find a proper firewall will protect LAN to LAN, WAN to LAN and LAN to WAN. Both inbound and outbound. As i said if data is exiting your highly secure network then i suggest its your exit point you look at. Your lack of knowledge regarding this shows how dangerous it is to have CCTV installers configuring networks without the proper background in networking and network security. And your welcome to have my IP information and logins if i felt the need to install them, However it would do you no good as my network would be secure with a properly configured, good quality firewall. You know the kind that actually can be deemed a firewall which protects all directions.

    What I did for a living once-upon-a-time was design software for machine vision inspection systems, so I know just a little >< about how photo imaging sensors work. And, yes, digital camera photography is one of my lesser side-hobbies, so I know something of how that technology works, too. You can insist that photographic cameras not be brought up, but that doesn't change the fact they use essentially the same technology and are guided by the same laws of physics (as we currently understand them). "your [sic] adding more pixels to the same area...": Bingo! And more pixels in the same area means the pixels must be smaller. QED. Tom, the pixel size directly relates to its light sensitivity. That's the whole point of this discussion. Provably false. (I've already explained why. I'm not going to repeat myself.) It is? Please show us the ™ or ® mark on Dahua's use of the term "starlight." Please show us where Dahua's technology licensees are acknowledging the use of Dahua's patented startlight technology. You cannot, because "starlight" is a generic term for imaging sensors and surveillance cameras that perform better than others in low-light conditions. This is evidenced, for example, in this Bosch press release: Bosch introduces latest starlight technology - The ultimate 24/7 IP video surveillance cameras just got even better, where "starlight" is mentioned with no attribution. And Dahua is using Sony STARVIS sensors, as demonstrated, for example, by Dahua DH-IPC-HDW5231R-ZE - 2MP WDR IR Eyeball Network Camera and other Dahua Starlight products which also prominently mention using Sony STARVIS technology. I'm not going to argue this with you any longer. I have design background, technology experience, facts and documentation on my side. You have beliefs based on what is apparently an incomplete understanding of the technology, which is now leading you to contradict yourself.

    I'm sorry, alpalp, but I do not have a recommendation for you. Some of the more experienced guys here I'm certain might have. A lot of people like BI. Maybe it's great. But I don't trust MS-Windows any further than I can spit, so I'll never know. If one of the Linux flavours is your thing, possibly Blue Cherry DVR? I may give that a go if things don't work out with Synology.

    You're welcome. As for Blue Iris: I can't help you. I try to avoid MS-Windows. As for the "other forum": If it's the forum I think it is you'll notice they sell BI

    Ubiquiti is expensive and out of date. Plus remember you need to run along side a PC ..... It has no monitor output qvis uk sells well in Sweden...... And the viper NVR is one of the best on the market now. NVR is compatable 720p upto 4K so a long time before its out of date

    Yes that's right what will you be using the system for ...home or business use ?

    Hi. It depends on which nvr you are going to use . It needs to be compatible some nvrs are only 2mp recording some are 5mp or 4k

    As far as I understand, FreePBX is simply a project adding a working webIf to asterisk. So everything should work as it does with a base asterisk. I run a asterisk on raspbian, no special version, just the stuff that you get with apt-get.

    Hi. No need to take anything down .....your network is only used for remote viewing with only using two 5mp your ok but I would look at adding later 4mp and even 2mp is small areas or you will need to drop FPS also remember you can use any tvi camera or 4 in 1 camera does not need to be hikvision if you have not bought anything yet I would pic TVT over hikvision security industry had another report yesterday on hik hack

    Hi either use ip cameras or get yourself a capture card and use analog .....analog is out of date so I would look at ip cameras. but a nvr is always better

    There are two ways to go about this: Find the output current rating on the power supply (I assume the Lorex NVR powers the cameras?) and multiply that by its output voltage. That will give you its approximate max wattage. UPS' are rated in VA (volt-amps), but it'll be close enough. The other way is to actually measure the current draw on the AC side using a true RMS ammeter. (That's the best way.) Then multiply the measured current draw times the line voltage. Next you have to determine whether the point is to protect your surveillance system and allow it to survive short-term outages, or to have it stay up for an extended time when there's an outage. (I note you list a "12V 10" PSU. If that's 12V at 10A, which would probably be about right for an 8-camera system [assuming about 15W/camera], then your want a minimum 120VA UPS. Depending upon the design, that may give you anywhere from 5-10 minutes of uptime [SWAG]). To a degree you can extend uptime by going with a higher-than-recommend-VA UPS, but there are diminishing returns with each bump in VA capacity. Reason is reduced efficiencies as UPS VA capacity goes up. For truly extended runtime you need an "extended runtime" UPS. They don't have greater VA capacity, but more battery. (They also take longer to recover because there's more battery capacity to charge back up. There ain't no free lunches.) E.g.: With a 120W load, a 120VA UPS may give you about 5-10 minutes of uptime, but a 360VA UPS won't necessarily give you 15-30 minutes. In fact: My old power-hog Dell 1600SC server had a 700VA APC SmartUPS on it. The computer + peripherals drew about 200W. The UPS had a runtime of only fifteen minutes with brand new batteries. Speaking of batteries: Make sure to buy a UPS with user-replaceable batteries. They have about a three-year lifespan. Also: Get in the habit of doing run-time tests about every quarter or so, to extend battery life. The UPS manufacturer should have a chart listing estimated run times for each of their UPS' vs. expected loads.

    Hi there, I just want to inform you in my case I do not receive anymore the notifications on my mobile phone (gDMSS Plus) when someone rings on the door. It looks to be a general issue Dahua must solve after Google has changed the push service , see reply from my vendor : This afternoon it has been revealed that Google has changed the push service for a number of Android versions and this has impact on a large part of the Android devices using IMOU or GDMSS. This implies that Dahua must solve it, just Dahua is currently celebrating Chinese New Year, which makes the solution just waiting a bit longer. Hope it can help you if you are in the same situation.

    Any time you allow Internet access to anything the threat level goes from "very little" to "a lot," regardless of what you try to do to mitigate it. For starters: Login access to your router from the Internet should be entirely prohibited. Period. Incoming connections should be on a "that which is not explicitly allowed is denied" basis. Proper, explicit port-forwarding rules should see to that. Default accounts should be disabled. Or at least have passwords or pass phrases so incredibly long and complicated they might as well be. If login access has any "break in attempt" detection, that can temporarily blacklist source addresses that get an account i.d. and/or password wrong "X number of times in time T," that will tend to slow attackers down so badly the likelihood of success is vanishingly low. Regarding LAN security: It's wise, when possible, to use VLANs and isolate IoT devices to their own VLANs. Also: If IoT devices do not need access to the Internet (e.g.: cameras talking to a local NVR have no need to swap spit with anything on the Internet, other than to occasionally check for firmware updates), they should be prohibited from doing so, either by putting them on their own network segments, using VLANs that don't have access to the Internet gateway, or by blocking them at the gateway. (VLANs enforced by managed Ethernet switches are more secure than border-router blocking. Separate LANs, isolated with internal routers are even more secure.) Lastly: You have to put it in perspective. Unless you're a bank, government entity or some other high-value target: Odds are anybody taking a shot at you is just what we call "knob-twisting" in the I.T. security field. They'll get in if they can, but it's unlikely anybody will mount a concerted attack against you. You're probably at greater risk from what you receive in email and what you browse with your web browser than you are with your NVR and cameras.

    I can't answer any questions about how many cameras you'll be able to view at once, because I'm relatively new to video surveillance gear, myself, and it'll depend upon your software in any event. But, as a retired Systems, Network & TelCom Admin with over 25 years experience building and maintaining networks (LANs, WANs, WLANs) for a living I'm going to suggest cameras <-> switch <-> powerline <-> router <-> powerline <-> NVR is probably not going to result in a happy outcome. First of all, powerline adaptors have highly variable performance, depending upon a variety of unpredictable factors. At the very least I'd obtain a pair and do network bandwidth, latency and error rate tests between Point A and Point B, then Point B and Point C before proceeding. I'd be surprised if you got sufficient low-error-rate bandwidth to support eight video streams. Secondly: It has been my experience that most routers (and I'm making the assumption you probably have either a common consumer-grade or cable company device) tend to be sub-optimal as network switches. Particularly common WiFi routers. In my opinion, based on experience: Switches to switch, routers to route, and WiFi access points to provide wireless access. Avoid WiFi and powerline where wired is feasible. As to WiFi vs. powerline: Whichever works best, which is highly site-dependant.

    Hi I've got a Dahua IP cam & I need to change the logo that appears while I access through a web interface? Is that possible if I choose to change it from firmware file (the bin file)?

    Cheers Tomcctv much appreciated I use no-ip and set it up myself Someone advised I set up a vpn but don't know how much money and effort required. Do i need to update firmware on cameras as well as the apollo?

    I have looked at the logs and this is the first time I was hacked. The day before some IP in Russia logged in and out and then the next day was hacked by IP address in Argentina Then hacked again IP address in Ukraine. This time changing names of cameras with message to update firmware? - friendly hacker?

    I got the same error, but everything local. I got one PC and one camera. Downloaded latest iVMS 4200 (2.4.xxx). Installed storage server and format a drive. Motion detection alarms works fine, but I can´t play the recorded. Probably nothing is recorded at all. Can´t understand how to configure this software that seems to be powerful, but a nightmare to config. Thanks, Magnus

    I have to say that the standard of CCTV work I have experienced in the UK is very good in the main. I have learned a bit from remedial works, I have seen the way other's do things and in some cases I have changed the way I do things because I have seen a better way of doing something.
