We do have a couple of cameras, one megapixel IP and one HD-CVI license plate capture camera that may work for you, however there will be a few things to keep in mind. You can see the cameras available here: http://www.securitycameraking......9-ctg.html

The 6-60mm camera (IPOB-TP2MP250L660-W) will give you the furthest distance and these cameras are generally made to capture faster moving objects such as cars. At night time, you'll be able to see up to 250ft away while the infrared LEDs are illuminated. This camera is a 12v camera but can also be powered using a POE switch. This specific camera can only record at up to 30 frames per second so if you're planning on shooting cars that are driving by at a faster speed, I would suggest going with the other camera that is capable of recording up to 60fps. This will help with capturing less motion blur from the speeds but you'd be fine with 30fps if you're pointing the camera at a location where cars must slow down such as an entrance or exit, or anywhere where there may be an access controlled gate. You can also record at 1080p resolution which would give you pretty nice clarity in comparison to most standard analog cameras.

I never recommend using a battery as a power supply for surveillance cameras because you'll be limited in the amount of time you can keep the camera running before you have to re-charge it again. You may be able to purchase or create a battery bank for larger record times, but this would take up a lot more space than you'd probably like.

If you're planning on viewing these cameras remotely, you would actually be accessing the recording device and not the cameras themselves. For the CVI bullet you'd need to go with a tribrid or HD-CVI DVR. You'd then port forward your router in order to see the cameras that are connected to it remotely.

These cameras are really not the best solution for mounting in a car, but we have had some customers who have successfully set up our products in vehicles and love it but it's a specialty type of setup that we do not support. There are companies out there that manufacture cameras made specifically for vehicles, but we do not carry these types of systems at this time. We also do not have anything that's both wireless and battery powered so if you're looking for that I'm sure a quick google search can help you locate a few companies that deal with vehicle specific surveillance systems.

If you do decide to go with our system, we do offer free tech support for the life of the product and we can at least guide you in setting up the camera and recording unit so that you can capture the best possible footage using our system. If there's anything else we can help you with, feel free to contact us here anytime or call us during normal business hours Mon-Fri 9am-8pm EST.
