Anyone know any specifics about this security camera?




Adam


I'm looking at a 700TVL Indoor/Outdoor Vandal Proof Dome Camera 130ft IR (Infrared), 2.8mm-12mm lens, Sony Effio 12V for a friend of mine. I cant seem to find out anything about he megapixels on it.

Anyone who knows what the MP on this camera, please help me out.



Answer
You did not tell us which manufacturer or the label on it.

That is because video resolution is not measure using "megapixels". That is a resolution measurement used for still images. Video resolution is measured using horizontal row count. In this case, 700 TV lines... without knowing which camera, there is no way to know whether is is capable of high definition or standard definition video - and we also need to know if the video will be transported over coax cable or using an IP network. Knowing the "megapixel count" is only on small piece of information related to resolution and potential video quality... the video compression used, cabling system and several other factors need to be known, too.

For residential installations, I use Swann or Lorex cameras. If the camera is less than about $150, expect it to fail in about 6 months. I've burned through the cheap stuff on eBay and the low-end at cameras from several places in a couple of months. The slightly more expensive Lorex and Swann cams just keep working...

Little help with Survelliance Camera Choices?

Well a friend of mine owns a bar, and there has been a quite of few car burlgaries in his lot. I am thinking of letting him borrow a few grand to help him get a few security cameras. We have been on the internet and there are so many choices. He is not looking to go all military or nothing just a normal setup. We are looking at some dome camera, and some bullet cameras. All of the images we have seen online have been pretty good but it is hard to tell at what distances the images are from. Basically, how good is the average camera at a distance of 20-50ft in a dark area. (limited light) These cameras will not be monitored so no one will be zooming in on activity or anything like that. Are cameras even able to get a good image, like facial features at night from an average distance. I know lighting will be a factor, but what is the average capability of a security camera at night. Even the images on tv you see are rarly good enough to see who the person actually is. You can see the activity but I have yet to see to many that you can look at the image and say yea that is the guy. Any people with expierence in this your comments are appreciated. Remeber these cameras we are looking at do not have zoom capabilities they are just the ones you mount on top of a building or on a pole in the lot.


Answer
Your friend needs to look for a high megapixel security camera system. They have excellent limited light capabilities and at least you can zoom in on the image and distinguish actual facial features.

Take a look here for example:

The video you typically see on the news is absolutely useless. It's a blob for a face, and unless the criminal is so stupid that they wear some kind of logo clothing or has very obvious features, you will never be able to identify them.

The company at that link has some awesome demonstration videos showing actual crimes recorded by their cameras. And you can zoom in on the perp's faces and it's as clear as a line-up. They also have good examples of night vison superiority.

Higher megapixel security systems are a little more expensive, but they actually perform the job for which they were intended. If you have a low-res image, sure, you can see the action... but it is completely useless for actually identifying and apprehending the criminal.

High megapixel security has even worked to pick up the license plates on vehicles fleeing the scene! And you do not need zoom in capability on the camera because the image resolution is so sharp you can easily zoom in on the existing image.

Definitely check it out.
