Will this be my best option you think?
i use the VDS2500 alot. it is also your cheapest option. by the time you have bought coax / power cable/ power supply.
the VDS2500 comes with its own power supply to run two 12v cameras at a range of upto 1300ft. you will only need to use your coax you have as power and both videos are transmited down the one coax. plus you will also have data that can be used to switch lights or detect motion alarms.
Where can I buy this?
