I want to make a surveillance system so that I am able to have a camera or two at my house and one or two at my office (about 1 mile away). They need to be able to see at night and perform well outside as thats where the majority of them will be.

I would like to be able to have them all tie in together so that I can view them remotely from one place, or preferably my cellphone or a laptop.

Thank you in advance for any help!

Start with a budget. Is this worth $1,000, $5,000 or more to you?

Also, since you don't seem to have any specific data network or security camera experience, you might consider hiring this out or contacting a reputable security company to do the work for you.

Being a mile apart tells me you will need two different systems. One home, one office. The biggest reason is the two different local area networks (LAN) used that will connect to the internet.

There are essentially two ways to do this.

1) Analog cameras connect to a DVR, the DVR connects to the LAN.
In this scenario, there are two options. One has the DVR being accessed remotely so there are data network security and segmentation issues to deal with otherwise the video data could easily overwhelm a poorly designed network. The other has the video being sent to a "service" - most of the manufacturers have this - and to see what your cameras see, you log into their network.

2) IP network based cameras are on a LAN. The camera views are accessed remotely so there are data network security and segmentation issues to deal with otherwise the video data could easily overwhelm a poorly designed network. If video is to be stored, then add in a computer of appropriate horsepower and hard drive size to store the video.

In all cases, be sure to add a battery back up system that powers the cameras, DVR, router, hubs switches, computer and whatever else is associated with the security camera system. It would be silly to have a "power outage" cause a security camera outage.

Cameras rated for outdoors, with night vision (infrared emitters) will cost a little more than small indoor type cameras. At the consumer grade level for analog cameras (that connect to a DVR), plan to spend at least $150 per camera. Lorex and Swann make decent ones. If you need "vandal resistant" or decide to go with IP based cameras, expect to spend around $2,000 per camera. Pelco makes good ones. If Pan-Tilt-Zoom functionality is required, the camera price increases to around $3,000.

The DVRs at the consumer level start at about $400 for a decent 4-channel system. You may need to add a hard disc drive if the one included is not large enough. An 8 or 9-channel DVR weighs in at around $650. A good Pelco DVR will be in the $5,000 range.

There are several more permutations, but the gist of this explanation is that your simple question does not necessarily have a simple answer.

can you record from the video channel on your tv?

my security camera must be set up to be viewed from the video channel on the tv. so, while the tv is acting as a monitor as long as i am sitting there i can see whats going on in my yard, which is the purpose of the system. I need to record-not sit and watch the tv for 8 hours. I'm trying to see which neighbor is throwing trash in my yard. I have been told you can not record from the video channel. But this is the station the camera must be on. any ideas.


Answer
Just take whatever cable is going into the video input of your TV and run it through a VCR, then you can record it.
