Hey guys I got this question on my website. I have not worked with the Geovision product before so thought I would post the question here. Let me know your thoughts. i have a problem to connect my cctv system over internet with my 3G phone with windows mobile 6.0 made in taiwan HTC TITAN II. i use cctv dvr card geovision GV800 software v7.0, I already set the internet requirement to be access over internet connection and I already access my cctv with internet explorer with success. but i have problem with my 3G phone that always failed to access the cctv system. i have already install the software for windows CE to my 3g phone but when i try to connect its failed( its said 'server close'. i dont know because the software doesnt support for 3gpp or i have to find another software that support for this application, please give advice Peter

There are a lot of options for home systems. Lorex has some decent professional systems. If your looking for some cheap systems but may be concerned about being able to return it if there are problems then you should look at what Costco has to offer. (if you live near one). They have some really basic systems for well under 1k. You could always look at Logitech as well. They have cameras that you can use with software you install on your PC. Again very basic resolution but easy enough to install and use for a home system. If your looking for long term support etc then working with a local cctv distributor would be a better option.

I guess it depends on where you want to end up with this. You may want to go with the card and have a system that may work with IP cameras as well. Then later on you can get a megapixel camera to cover the whole front of the house. Field of view is a big deal though. It's all about setting your expectation of what you will be able to see realistically. The wide angle fixed lenses are fine for fairly close objects. If detail at a distance is a concern then you need to consider using a varifocal lens. Peter http://www.cctv-security-systems.com/cctv-field-of-view.html

If you are only needing one camera you might look into the Logitech cameras. They have a nice camera and software that you can connect up to your PC and do all your recording etc. They will be a little more than your budget but for only 1 camera it is a nice home system.

I cant say that I am expert with this but more than likely it is one of two things. 1. The ip addresses that are assigned are entered incorectly (or some part of the subnet mask, etc.) 2. The port forwarding is not set up correctly. I would also reinstall the software to make sure there is not a problem there. You have to double check the addresses and then make sure your testing from outside of the network. What routers or firewalls are in place? I know that may not be much help but you have to take care of all the little things first. Thanks Peter http://www.cctv-security-camera-systems.com

Dont know that you have to use Extreme cameras unless your in a very very cold climate. Otherwise you could go with enviro/bullet style cameras and could use IR. Just need to verify the effective distance of the IR on the camera. I know GSP America has some nice enviro IR cameras.

Thats good about the DVR. Just make sure you have enough storage. At 30fps it will add up fast. Not sure what the picture may acutally look like. The quality would be better with the SuperHAD chip. I would check that the HQ1 camera also would have an Auto ICR (removable cut off filter). If it does not have that it wont work very well with IR any way. Although when your dealing with IR and darkness its hard to get a real high quality image anyway. Thanks

I dont see that you have anything about your lens choices. You do need to take into account the distances and what is needed to be viewed. It would be a mistake to assume that a megapixel camera will solve all of the view problems. In most cases you could probably still use standard resolution cameras with the right lens choice. You also need to verify the classification of PoE on the cameras and whether or not the PoE switches you are using are guaranteed per port switches or total budget switches. It will make a big difference in how many cameras you can connect to it. Not all switches or cameras for that matter are the same.

Check the camera settings. In some cases the camera can be switched from NTSC to PAL. If not then the first guy is right. Find someone that you can trade the cameras with. So on the NTSC system with 4 cameras they do not record in color? Are they color cameras?

I will chime in. The IR illuminator would be very helpful but not entirely necessary. But for only $70 why not have it. I think you could do better on the cameras. The HQ1 chip is not Sonys best chip and 480 res is not the highest resoultion you can get. You may want to look for something in the Sony SuperHAD with 540 TVL if you dont mind spending a little more. I am concerned about the FPS on the DVR. 60 FPS at 720 x 480??? That doesnt seem like very much? Also you really dont need to be recording at 30 FPS. 15 FPS is more than enough to get what you need. Even 7.5 would be plenty. Better to go a little lower on the FPS and increase the resolution. Are you planning on just using fixed lenses in the cameras? Sounds that way, which is fine in a house. 4mm fixed lens will cover most of what you need. If you wanted to get a closer view of the garage you may want to go with a varifocal lens that would allow you to zoom a little tighter. If you want to see indoors in the dark you can just use a camera that has some IR built in. You wouldnt need much. Just 12 to 24 leds would be plenty. I would only use the illuminator outdoors. Doing the baluns with the power and video should be fine with the 24vac for the distances you probably have run. Well thats my two cents.

I have some 9 channel systems available that could meet your needs. We only have a few of them left and are discontinuing them since they are not very popular. You can contact me at sales at gspamerica dot com. I cant put to much personal info since I am new to the forum

It seems there is a lot of confusion on this topic. Here is how this works. You have equipment that delivers power (PSE) and you have powered devices (PD). The PDs have one of 3 classifications currently in the PoE standard. Class --------- Min PSE Power --------- Max PD Power ----- Example PD -- 1 ------------ 4 watts ---------------- 3.84 watts ---------- VOIP Telephone -- 2 ------------ 7 watts ---------------- 6.49 watts ---------- IP Camera 3, 4, 0 ---------15.4 watts --------------12.95 watts -------- wireless AP Most of your IP cameras will be a class 2. However there are a large number of manufacturers that use a default classification of 0. Now the cameras may only need 7 watts of power however the PoE Swtich will assign 15.4 watts to that port. A common misconception is that the switch "pushes" the power to the device. The truth is the device pulls the power from the switch. So even if the switch is assigning 15.4 watts to that port the device will only pull the power it needs. (one of the safety features of PoE.) One problem area is that a PoE switch (PSE) can be one of two types. It is either a guaranteed power per port switch or a total power budget switch. For example if you have a 4 port poe switch that is guaranteed per port of 15.4 watts you can connect four class 0 devices to it with no problem. However in a total power budget switch that has a total budget of 30 watts you could only connect two class 0 devices to it. So there are two things that everyone needs to push with the manufacturers. 1. Of cameras - clearly mark on the camera itself what classification of PoE it is. (and on spec sheets of course) 2. For switch manufacturer's to clearly identify whether the switch is a total budget switch or a guaranteed per port switch. I have a training video on this if you search for understanding PoE on vimeo dot com. (and I don't sell PoE equipment)
