Old surveillance cameras usually send a video feed to an external recorder via wired or wireless connection. Today, you can find plenty of DVR spy cams that are capable of recording footage themselves. These devices are proving to be popular as they have the following desirable features:

Removable Memory Cards

While some models might have built-in storage, most have removable memory cards that are more convenient. These can be taken out of the unit when you want to view or copy the contents. These cards are compatible with a wide range of electronics including smartphones, Android boxes, tablets, and computers. It is easy to swap memory cards when the current one is full so the cameras can continue to record right away. They can also be upgraded up higher memory capacities if the internal card reader allows it.

Smart Designs

Spy-cams come in an assortment of designs. They are usually shaped in such a way as to blend in with their environment. Subjects must not suspect that they are being recorded so these devices are hidden in plain sight. They could be disguised as clocks, air purifiers, and the like. As such, they can be placed at excellent vantage points without any problems. They could be close enough to the subject to get vital information without arousing suspicion.

High-Resolution Video

Camera technology has improved by leaps and bounds over the years. Most used to take grainy videos that were not very useful. Now they can capture videos at high resolution and in full color. This makes it easier to identify people and things even from afar. If the objective is to catch a thief or any other suspect in the act, then you will be in a better position to do so with these new technologies.

Night Vision

Indeed, some models even have night vision capability which allows them to record things that take place in the dark with better detail than an ordinary camera. A lot of crimes take place at night so this kind of feature is excellent for security purposes. The darkness will no longer be used as a convenient cover.

Motion Activated Recording

If a camera has been placed in an empty room, then there is no point in recording all day. It would be prudent to save storage by activating only when necessary. Motion-activated recording ensures that all the action will be saved while ignoring the static.

DVR spy cams are useful tools in a diverse range of applications, especially with these features.
