Hey Everyone, Having an issue where my exports in avi format are not properly sync'd. The raw format looks good. The video gets ahead of the audio. I've tried different camera/mic setups with different VMS. I've used Axis P3204, P1346, P8221 (Axis Mic) with Milestone Professional, Milestone Corporate, and Exacq. Driving me nuts because the customer needs avi files. I was able to get it close using YAAI, but that's not a solution. The customer isn't a video editor. Any ideas? Thanks!

Exacq is a reliable system and as a plus it has clients on Windows, Mac, and Linux (which is rare). If you don't want to invest in a huge storage server, get one with enough processing power to do the video and add an ISCSI device if needed for archiving(synology is my favorite). I've got Exacq servers that have been running without any problems with a couple of years (thank you Linux stability). Another road to look down is Avigilon and Milestone. Since you have mostly done analog, Avigilon would be a good road to go down since it is fairly straight forward if you are not technically proficient in IT. As a plus their cameras are fairly economical. Stay away from the cloud, with that many cameras the client will almost need 40Mbit/s upload with 32 cams. IMHO, cloud surveillance is not near ready for production use. If you want RMR look at doing a maint. contract or equipment monitoring via a network monitoring software and establish some sort of SLA (much lower overhead but requires some technical know-how). Most of the cloud providers offer low storage at a premium cost and the camera is required to have internet access to record video. Side note, if you want to reduce your cost a little, you can get buy with running Cat5e since the runs won't be Gbit. Only reason I would run Cat6 to cams is if I expect interference (just my two cents). I would also recommend Axis over Vivotek if you can. Good luck w/ your project and let me know if I can help!!

Don't use Axis Camera Station, I've talked to rep's from Axis and they said they wouldn't use their own software. "We are a hardware company not a software company" -their words. I've tried to use Axis Camera Station and it was clunky software and slow. While Avigilon is not my first choice, I have used it before with encoders and it works fine. You may want to try using Milestone and the Axis encoders (you can get a 30 day trial from their site to give it a shot). Good luck w/ you project!

I've used two of the ones listed above, the axis and mobotix. I usually go with the mobotix unless there is a budget constraint then I'll go with the M3007. Image quality seems better with the Mobotix.

SSL = on SMTP Server = smtp.aol.com SMTP PORT = 587 SEND EMAIL = (your email) SEND PW = (your pw) RECV EMAIL = (your email) Also make sure that you have a DNS server in your network settings. Try 8.8.8.8 as the server so it can resolve the smtp server. Also try it without the 00 in the port number.

There has to be a recv email otherwise how does it know who to send an email to? The send email and send password authenticate to the smtp server. The recv email is who gets the alert email.

Google "AOL SMTP Settings" and the recv email and send email will most likely be the same. The password should be your password. That should get you going or close at least.

Cheapest way to do it is going to be buying an access point from say Best Buy and put it up there. If you had roughly $200 to spend, I'd try putting in 2 Ubiquiti Unifi access points (one downstairs and one upstairs) and then you would essentially have a 1 large wireless network.

What is the weather like there? You may not need heated and cooled enclosures. If the lighting is good and cost is a factor I'd go with Axis M1114-E outside and M3204 for the inside. Sure they are probably more expensive that the Dahua, but in my experience you get what you pay for. And with the Axis you won't have to have a DVR or VMS, you could record straight to a NAS device. I've had good luck with the Synology product line. Not sure what the recording requirements are, but I'd start with a 2TB NAS. Good luck!

A little google work didn't net any results that seem worthy. Not trying to be an Axis fanboy here, but the P8221 audio module can do this too. You just create an event that when audio goes to this level, close this relay. Might be a little too pricey for your application but it would get the job done. POE too!

I've used this feature with Axis cameras, you can set events to be triggered if the audio reaches the configured threshold. This functionality is built into the cameras, but you need to make sure it either has a built in mic or one is attached to it. I'm sure a lot of other manufacturers have this same feature.

That really depends on what you are looking at with the camera. Pretty much means that it sends an I-frame(entire image) every 1/4, 1/2, 1, 2, 3 or 4 seconds. A general rule of thumb is the lower that number, the better the image but the higher the bandwidth and storage costs. For fairly low activity scene a higher rate is fine, and for busy shots go a little lower until the video looks right.

Just creating a camera VLAN won't decrease traffic at ton, close to the same amount of data will remain to be passed, just now the switch has to tag it differently. If you have a 100Mbit port, that is the same capacity whether it is a trunk or access port. Sometimes trying to VLAN everything on networks just over complicates the network. Essentially a VLAN separates a broadcast domain. Can you make 30 cameras saturate a network? Absolutely Can you configure those cameras optimally to reduce network loads? Yes. It really depends on the network and camera choice. The bandwidth of a 720p camera is a lot different than a 5mp camera. Find any network bottlenecks, look at switch bandwidth usage, do some bandwidth calculations, then determine the best route to go. You don't have to have a fiber backbone, but a Gbit backbone is probably a must. Without more information on the current network, it is impossible to accurately help you.

A few factors here that can play a role. What is the signal level? Is this in an area that would have a lot of noise in that spectrum? LOS isn't everything, you also need to make sure you clear the fresnel zone. And just because an ap can handle 54Mbps doesn't mean that is what you get. As the signal gets weaker, the available data rates decrease. If you ping the cameras, what is the delay? Have to done a speed test from one end to the other? There are a lot of things that can be causing low bandwidth or latency and a lot of things that can help you out. Wireless links can be tricky if you haven't worked a lot with them.
