Space for equipment in your remote sites is often in short supply. Racks fill up quickly, and the more space you use for support equipment (like remote monitoring devices), the less room you'll have for other critical gear. Some small sites might not even have any rackspace left at all. You obviously can't leave your mission-critical gear just sitting on the floor.
Many manufacturers only offer rack mounting. But you can't settle for that if it's not right for your application. It's important that you find the best solution for your network. You need a manufacturer who gives you several mounting options.
DPS Telecom offers several mounting options:
This option is standard and the most popular among manufacturers. Racks are either a standard 19" or 23" in width. Rack mounting requires rack ears to attach your device to the rack. While this is the most common option, the main drawback is that you're limited by available space. The TempDefender G2 is one example of a rack-mounted RTU.
This is also a standard mounting option, but it requires extra hardware. A DIN rail can be mounted to a wall or attach to a standard rack. With special brackets, devices are then mounted to the DIN rail, like books in a bookshelf. While a DIN rail on a rack does consume space, you can fit more than one device across it - making DIN mounting more space-efficient than rack mounting. The NetGuardian DIN is DIN mountable.
Wall mounting also requires special brackets, but they are simple and allow you to mount your device to any flat surface that accepts screws. They're great for mounting your gear to the inside of a cabinet door when space in the rack is unavailable. You can also mount the device to any wall. Aside from being flexible in placement, wall-mounted devices allow for easier wire access for devices with ports on both the front and back. When wall mounted, "front and back" become "top and bottom", making ports much easier to reach. The NetDog 82 IP G2 is wall-mountable.
