Recently, the gate to our backyard had one of the slats kicked outward. Yep, whoever it was, they were in the yard trying to get out. We have a large mixed bred malamute, he has a nice disposition towards kids, who probably notice the person in our backyard. However, lately he has been getting some abuse and we don't know who is getting into our backyard. So, I would like to put in a hidden camera that I can access from the web anywhere at any time and/or get phone text alerts. I've check several companies and they are pricey. I'm not above building up a system, but I'm not familiar enough to know where to start. Can anyone help out? Thank you for responding in advance. Bob
I designed a camera once with a chip from Aptina. I believe the partnumber was MT9V125. It was really simple, designed for automotive guys. Its intended application was for backup cameras. All you had to do was apply power and the outputs started wiggling. The output was NTSC. You did need a lens for it though; I found a PCB mount that was plastic and cost like $5. I am not sure how far you can run the output from this part down a cable. If you need to run the signal far, you might need a signal buffer.
Wireless cameras with net access are pricey because they are hard to develop and build. It would likely take more in raw parts and asociated dev tools to build up a workable solution for single unit project. It's definitely not out of the question, but the magnitude of a project such as this would be diving into the deep end in terms of both time and money. Amazon has several sub $100 finished products that would do what you want.
I think this is prob what you're lookin for:
Cameras are bat powered, and It works from your computer or smart phone.
The Cisco-Linksys Wireless-N Internet Home Monitoring Camera is about $107 on Amazon
and Foscam FI8918W Wireless/Wired Pan & Tilt IP/Network Camera with 8 Meter Night Vision and 3.6mm Lens (67° Viewing Angle) is $78.
I don't know how well either of these work or if they are weatherproof or resistant.
Try CamWiz software plus a Logitech webcam. You can use an powered USB extender to get the cam out to 10M or more.
CamWiz can send SMS or EMS (through your provider's SMS or EMS gateway), or you can have an email sent, for "instant" phone notification of movement. Of course you need an iNet connection for this.
If you want to be sophisticared, use a Foscam PTZ cam and control it remotely (there are Foscam knockoffs cheaper than the real thing if you don't need any support... but no support isn't for the faint of heart the first time around). Foscam is cheaper than an commercial PTZ cam by nearly an order of magnitude, but you lose a lot of reliability vs. a commercial solution. A broadband connection is the only practical way to implement this. (control can be via a DN you rent, via smartphone or other browser)
These are the solutions I am currently using.
Note: you may want to have unlimited SMS or EMS until you get the bugs worked out. Receiving hundreds of EMS messages due to the grass waving in the wind can be expensive if you have to pay for each message.
Also I use Digi-Watch same as above with messaging, pre-recording,web use stc -I recommend it Have been using it for 2 years now in a security situation identical to above
With some innovation along the crack lines a free version can be had
