Everfocus IP camera EHN vandal proof serise overview

You know this camera means business as soon as you pick it up, the weight and strength of the metal housing is impressive and it can also handle the pounding of a ten pound sledge hammer.



The screws that keep the enclosure closed are a different pattern so your phillips, flat head or allen pattern won't open it. The cable glad has 3 openings for cable and you can easily attach your conduit and tighten it for a weatherproof solution, you can also unscrew the back knockout and run cable that way.

Another feature I'm really digging is the two way audio and the 3 to 9mm vari-focal lens should have a perfect monitor screen shot if your looking for a wide field of view. I just wanted to vouch for the construction of this camera for a IP weather rated outdoor solution. Check out how to network this camera and I'm sure it's something you can't handle.

Replacing your old CCTV system with HD Cameras? Good idea.

Replacing your old analog cameras with new digital HD cameras should be an easy installation, let's check out the High Definition CCTV Security System.

HD cctv is considered by many as a subset of megapixel and is defined by a specific resolution at specific frame rates with a specific aspect ratio. A camera with more than a million pixels is by definition a megapixel camera. The lowest resolution security camera with a megapixel number is 1.3 and provides 1280 by 1024 pixel resolution and is the 1080P camera.

The 720P HD camera provides images that are 1280 by 720 pixels giving you 921,600 pixels and is short of the 1 million mark, so your 720 high definition camera is not a megapixel camera but many people feel it's close enough so they call it a 1 megapixel camera. If your a installation contractor make sure your customer has a clear understanding of this. I've seen it cause issues with the end user after the installation has been completed.

Traditional analog cctv cameras providing 4CIF resolution offers resolution of 704 by 480 pixels (NTSC) or 704 by 576 (PAL) after the signal has been digitized in a DVR that corresponds to a maximum of 400,000 pixels.

When designing a CCTV system two types of coverage areas get talked about, a wide field view and a detailed specific view. In your wide field view 20 to 30 pixels are enough to represent one foot of a scene. For your detailed specific view of certain images such as cash, face identification, factory assemblies, the demand can rise to over 80 pixels per foot. Here's a cheat sheet I keep on hand just to remind me of what pixel count will fit my field of view best for my location.

Still reading? Good, because I have a about a 30 minute presentation from Everfocus regarding HD cctv. Everfocus is a camera manufacture and has been in business for many years providing solutions for commercial locations. Let see what they have to say.




Now that you know you can use your existing coax cable infrastructure your installation is already half way done! Are these HD cctv security cameras also the same as far as the construction? Yeah! Let's check out a couple from our YouTube Channel.




Here's a look at a HD pan tilt zoom camera.




Don't forget that you will need to also install a High Definition DVR for your new HD cameras. If you only need high definition at a couple of locations such as a cash register, hybrid digital video recorders are available to provide you more security at a more economical price.

Now that you have some knowledge about HD cctv are you ready for six times the resolution over traditional analog cameras. I knew it!

What type of cable should you use for your security cameras?

As you know security cameras are everywhere, have you ever wanted to know what kind of cable they use? The most common cable installed is a "Siamese Cable" that consist of a RG59 coax cable for the camera signal and a 18 gauge 2 conductor cable for the power. The jacket on the "Siamese Cable" covers both of these different cables now making it one cable and easier to pull and install.



When the 2 cables have to split at the security digital video recorder the RG59 cable gets terminated with a BNC male coax connector and the 18/2 cable attaches to a power supply. If you have multiple cameras that need power you might want to consider installing a master power supply to help keep your installation clean and organized.


It's cool how the master power supply has a fuse for each channel in case of a surge in power, you pop the fuse not your camera.

12 strand fiber optic cable by Corning Cable Systems

As you know Corning has a few different types of 12 strand fiber optic cables. Right now we're going to get to know Corning part number 012K8F-31130-29 much better.

This number is part of the FREEDM ONE design. It's flame retardant, UV resistant and the indoor/outdoor rating allows for aerial, duct and direct burial applications with no need for a transition splice when entering the building.

The tight-buffered construction facilitates easier termination for low fiber count applications in your local area network and eliminates the need for fan out kits. Color coded to the TIA-598 standard for easy identification.

The small diameter and bend radius of the cable also allows for easy installation in space constrained areas while the innovative water blocking technology is ideal for outside plant applications. The all dielectric cable construction requires no grounding or bonding and the jacket is rugged, durable and easy to strip.

Let's get a better look at this cable from our YouTube Channel



Now that you know Corning part number 012K8F-31130-29 is more than a 12 strand, tight buffered, riser rated, 62.5 multimode cable, I think your ready to pull that fiber.
